Firefox Gecko, "which we lost"

Firefox Gecko, "which we lost" Evolution is on, and weaker, slower and ineffective organisms are dying out. Not so long ago we spent in the abyss of the history of the Opera-1? looking somewhere into the distance, silently listening behind the sobbing of sympathizers. Unlike the body of the last animal from the Red Book, it could still be used for 2-3 years, and the users did not look like necrophiles. A similar situation is repeated with Firefox on the Gecko engine with the latest most convenient version of ???. There is a lot of useful and habitual functionality, not only built-in, but also in add-ons (extensions). Even reduced performance is not the basis for the transition to a new version, if several useful functions are lost with it. And with the old engine there is something to lose
Let's take a look at the list of what else you can use in the old version of Firefox and with what successes there is a replacement and restoration of this in new versions. What is completely new, for which it is worth all to throw and forget. (Actually, it's not necessary, because you can open the old and new versions at the same time.)
context containers (March 2018).
Nevertheless, the presence of the already running version 56 "Gecko" with a number of old add-ons - there is an argument to at least continue to use them until the new ones are ponabeobutut. In fact, unlike the earlier versions of Firefox (up to approximately 25-30), when more than about 2.5 GB (about 20 running tabs) were used to expand the occupied RAM, the latest versions of 5X continued to work even at 5.5 GB, and only the general lack of memory in the computer (at whom as, but I on variants with more than 8 GB of RAM did not test). Let it be slower, but the pages open and perform their functions.
Therefore, I revised the latest versions of Firefox (51-56) in advance, in October-November 201? to see how well they support the extensions at the time. I personally have a couple of dozens of extensions for a long time, which, undoubtedly, not everyone will survive the engine change, but they have a benefit and convenience, so it was interesting to prepare in advance.
It turned out that without any profiling (the ability of Firefox on the same computer to work with different accounts simultaneously in the same OS) it was possible to run in turn different installed versions of Firefox and install various add-ons on them. In addition, as a separate version, a development (beta) version of Firefox was installed to simultaneously see what awaits us. The history and account of Firefox at such transitions began to be a little confused, getting then to the older, then to a newer version, but in general this approach allowed choosing the most convenient stewardess .
Why choose among a few? The fact is that the developers of the extensions started to fuss and change the extensions, so it was not only necessary to look at the browser, but also to choose the version of each extension (add-on) that worked in this version of the browser. In particular, I wanted to find the moment when Firebug was finally abandoned, because the built-in debugger is still unstable (sometimes the DOM tree is missing). With him it turned out that Firebug was abandoned to the 51st version and I decided that it would be inappropriate to dig further and look for what version works.
With versions 51-56 it turned out that earlier versions become more and more primitive, with obsolete expansion bugs in particular, so if you keep the old Firefox on your computer, it is advisable - one of the last two versions (55 or 5? taking into account minor indexes - choose the last ).
In this case list of releases Firefox we see any versions for any OS, and, in particular, for the 56th version we see that the last stable release is ??? (or ??? you can try if you do not want to see the list of add-ons of the formal record as "obsolete").
Note that if you already have a stable latest version of Firefox on your computer that is more than or equal to 5? and you want to install the old one, I would recommend using Firefox profiles , so that you never get confused with accounts and their history and the simultaneous inclusion of different versions. But for the purposes of the experiment, if you know well what you are doing, you can do it without it, but do not run different versions at the same time (there will be no troubles, but not the desired one, but started at the moment, as far as I remember). But if the new version of Firefox stands as "developer" (beta) or "Aurora" (alpha), then they are able to work on their own with different profiles and accounts, because the registry uses different hidden data, and therefore, to deal with the profiling system do not have to.
Then, for those who want to install their usual add-ons, you need to carefully and carefully dig into the history of versions of each addon - they change and often become incompatible, tk. developers try to keep up with the current version and site offers the latest versions, often claiming that for this version of the browser and this add-on, "there are no working extensions."
So, I installed the correct add-ons for each of the installed versions of Firefox and tested them. With the described approach (it was, I will remind you, in October 2017), each version worked without profiling, did not affect one another (if not run simultaneously), and it was possible to evaluate the optimal version of Firefox for old extensions. It turned out that the last old version of ??? fits best, and the messages "out-of-date extension" can be ignored. This version supports the most recent versions of addons I use, so it proves to be the most acceptable.
There is a problem with the security update of this version. It is not considered to be LTS (long time support), so updates do not come out to it, and already from February-March in the window of Firefox messages appeared about the need to update the version. But while she does not refuse to work, although vulnerabilities or errors can somehow play a role - here the user is left to himself and his common sense in terms of when to switch to the current version with the Quantum engine.
There is another option - to use LTS, which Mozilla calls ESR (Extended Support Release) with the number 52.x.xESR. For example, now there is with the release date of 26-Mar-201? i.e. we see a constant work on this release (win-linux-mac) and 17 releases, starting from 06-Mar-2017. Unfortunately, then you have to put the old versions of add-ons, namely they keep some users from moving to Quantum.
How are things with the new add-ons?
Briefly - very much, about 40% of interesting addons are buried and not supported in Quantum, and some of the most important addons work badly, with errors that are not in the add-ons for version 56. Not for everyone, of course, these add-ons will be "the most important" I, for example, mean by these words 2 addons - Tab Mix Plus and Session Manager. Some of the add-ons work relatively well (errors are not identified or insignificant): Adblock Plus, Greasemonkey, Stylus, Colorful Tabs, uBlock are the ones that had to be tested and used in beta versions 59 and 60.0b11 at the moment. For their versions you can follow here , but, in general, in each branch of releases in releases Firefox have automatic update tracking, which if desired (not recommended) can be disabled if you want stable browser properties.
The statement above should not be understood absolutely - there will always be errors in add-ons, and add-ons will not be needed for someone. I describe here only my own opinion and experience, which for the other set of addons will be different.
List of resurgent addons
Their authors continue to support Quantum on the new engine as WebExtensions.
ColorfulTabs new , old - colors the backgrounds of the headings of tabs. It was actively supported earlier and aspired to be compatible with other addons, continues this approach now.
Tree style Tab - heroically reborn, the author did not give up, but the new is still worse. Most likely the interface API Quantum is not enough and not debugged, so see the second list below.
Im Translator - A shell for Google translation between many languages. It felt good the year 2 last, it settled, but the transition to Quantum led to temporary instability of the interface, which did not prevent it from using.
S3.Translator - Another shell, also normally survived the transition between the engines, and while her developer was looking for new forms of expression interface, which in the end was beneficial.
Tab Session Manager - session manager, not strongly tested by me, but can be an alternative to the vanished super popular Session Manager
Imagus - Show enlarged images when hovering the mouse and some more hotkeys for viewing pictures. It is very useful to less open subpages and new blocks for viewing or when an increase to the native size is not generally provided on the webpage - quite a frequent case, it turns out.
The list of addons, "which we lost"
Based on this experience and evaluation, I will quote the "swan song" of those add-ons that will be irretrievably gone, but could or have been useful throughout the history of Firefox Gecko.
Previously, every year or two I brought the lists of add-ons that I used, and some of them turned out to be useful: for Fiferox on 1? 2012. , Firefox 29 (2014) . Later, for quite a long time, there was no need to revise the lists of add-ons, the stability time stretched as far back as 4 years. For our time this is a terrificly long time. And we conclude their work with this "swan song", maximally delaying the end. Therefore, the list was not published immediately on the release of Quantum, and not everyone needs this list, but someone "will break through nostalgia."
So, we accept the list of swan songs from the group of addons selected during the years of use. (By the way, to find more extensive lists of other authors - just type in the search for Yandex or Google or Habr the words "Firefox addons" or "Fifefox addons".)
Tree style Tab - old versions of - with a tree-like style of tabs, saves from the number of tabs, folding the branches of dependent tabs; long-standing and legendary addon, constantly standing in front of the rest in terms of the number of functions and supporters of its use. He did not die, it exists for Quantum and uses the hardware capabilities of the new sidebar of the browser, but has such shortcomings now (Win7 /10):
when you return to the saved list of tabs in the sidebar it forgets the levels of their nesting, but keeps their order; if you do not use sessions, then you can work;
there are errors when turning on and off the sidebar - at times the tabs do not work in it, but fortunately, the tabs are always duplicated in the horizontal bar at the top (or bottom), even when not needed;
It is impossible to remove the horizontal tabbed bar if it is not needed (when using the sidebar).
There are, of course, a number of minor other shortcomings (problems with the size of the headers of tabs - they always were, but in the old version everyone found their niche solutions - in particular, not all the options are right, if you want the ColorfulTabs add-on), and in Basically - it works. And with the new version - their inconveniences, which someone seem insignificant, but not all.
In the rest, apparently, work on it is actively being conducted, and once all of a sudden he will arrange everything, but for the time being - no. Already a lot of factors can affect the quality, and the OS used too.
Speed ​​Dial, only old versions of - the famous patriarch of addons, the answer to the Speed ​​Dial Opera at a time when this interface was revolutionary. Now his ideas are implemented in each new browser, with one exception - this is user-controlled, and those implementations are always "not very". Instead of the built-in tabs in Chrome, vying to offer options, analogs. Often the complexity of analogues ruins their stability. The same in Firefox - has always been stable.
OmniBar - combining address and search strings. A constant loser because of the freedom of the Gecko interface. Once it was stable, then I lost this property, or it was not supported in Win. In Quantum, it seems, is no longer needed. But why there in the list of "Items into the toolbar" the element of the search string is saved ??? Maybe, once the built-in association "does not shoot"?
Classic Theme Restorer, only old versions of - the one that is important for the transition period (from the 28th version), an addon that allows you to gently abandon the add-on bar, postponing its demise, reducing the height of the address bar and restoring some control keys on the interface elements. Formally, it is logical that it is not further supported, but was most useful for customizing the interface.
Session Manager - session manager; it seems that he was favored by the browser team, he was officially recommended, and suddenly, he came to an end. Probably decided to move the functionality to the browser? But so far this functionality is not visible, and we have to look for a replacement in a new engine.
Simple Add-on Manager - makes viewing and managing add-ons, user scripts and user-oriented ones much more compact, more convenient and does not lose any value. Since it is strongly tied to the old interface - it is logical that in this very form in Quantum is not supported. But there is as yet no substitute for him (is there now?).

Tab Mix Plus - Tabs manager, died with the old version. Was very popular. I even helped to fix something in tabs that the Tree Style Tab could not do, and I had to turn them on both (the pole is still Classic Theme Restorer). Not always such a bundle worked equally in different OS. The last year or two all settled, but now it has collapsed. (Do we get used to it?)
We mention 3 very specific, but necessary in the old engine addon for developers.
It's All Text! - allowed to edit textarea-fields in his or her own text editors (there was a button for jumping over there). But this is not the main thing. The main thing - it helped edit the userbenches in your editor. As - described here: . Pay attention - not in the new display mode, but in the old (first version), without the syntax highlighting. And it suited for years, and there was no other way of working with user-oriented languages. they are pretty tightly integrated with the addon Stylish. Or the browser interface - or your own text editor. Of course, your editor was more convenient.
Now in Quantum it's gone, for the display of user interface appeared an interface similar to Chrome, and in it once (but not immediately) there were buttons for importing and exporting to Mozilla-format of user-defined styles (when editing a specific style). Adding extra Ctrl-C - Ctrl-V, which successfully allows you to do without this addon (I repeat - for the old version of showing the user experience without highlighting) We killed a mammoth, and he was useful.
ViewSourceWith - You could look at the source code of the page in your text editor. It was especially useful for a long time when there were few dynamic pages, and the Web Inspector (which by F12 or Ctrl (Cmd) -Shift-I) was still small.
UserCSP - Managing the Content Security Policy (CSP) for debugging or for generally running scripts in some places, at least in your browser.
And one that became unnecessary a little earlier (more than a year ago and before the 51st version - the older ones did not check, because many other add-ons in the 51st already began to look worse than their latest versions), because he himself to itself broke and ceased to be supported - Firebug. He went somehow ingloriously, and flopped long before long, so we will not talk about him bad.
This list is very limited and subjective, but it can help remember some extensions or the last time to find out about what they were. Or what seemed impossible in a browser without extensions is possible.
Should I use Gecko next?
For more than 90% of Firefox users, the answer is "no", due to the fact that they do not use add-ons (extensions).
The answer is entirely determined by your interests in the old extensions. Continued use of version ??? shows that it is too early to write off and because of the stable operation of old and "lost" extensions, working with it is more comfortable. Of course, you need to test the web pages of your projects on a new engine, taking into account a number of factors specific only for you, and it's still acceptable to use it, just like you used the old Opera 12.x earlier than those who used to its interface.
You should also remember about the lack of security support for the browser version 5? but about the availability of such support in 52.x.xESR (update this version regularly).
The transition does not cause problems, the pages open faster, but why choose something that is still less convenient due to the disadvantages of add-ons? Everyone decides this, based on the usual add-ons for the old version of Firefox. And for a large part of the users of this question is not at all, because it has the main browser - not Firefox. We look at the actual statistics of using browsers in RuNet: .
