The hard fork was "Waterfox Classic", which just became unsustainable to maintain. Rather than support for XPI (which is just the packaging for Firefox webextensions), the current version of Waterfox does still support bootstrapped extensions - in theory anyone can still write one, with access to all the privileged JavaScript APIs typically not accessible to MV2/MV3 webextensions. It's not widely used though, there are two repos I'm aware of that take advantage of this: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master... https://github.com/onemen/TabMixPlus/

Though for the full value I personally really also need some sort of interface that can show individual page visits in order to answer the question "What other pages did I visit at that point in time?" (sometimes I don't remember the right keywords to find a certain page again, but only some other page I visited during the same browsing session). The built-in history view is only of limited value here, because it always only shows the most-recent visit, so as soon as you visit a page again, it moves to the front of the list again and loses its original place and history context. As usual, there used to be an add-on for that, which was subsequently broken by the move to webextensions (and even if somebody wanted to rewrite it, the webextension API doesn't cater for its full functionality). Thankfully some kind soul has maintained a version

Keyconfig and other legacy extensions are still available for modern Firefox with a modified userChromeJS: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master...

UI customization is fortunately still alive in the wake of XUL extensions. A /r/firefoxcss mod has a wonderful collection of code snippets that they maintain, which you can browse here: https://mrotherguy.github.io/firefox-csshacks/ and they created a userChrome.js loader here: https://github.com/MrOtherGuy/fx-autoconfig My favorite customization repository is https://github.com/aminomancer/uc.css.js - which really tests the limits of what is and isn't possible with userChrome.css and .js. My favorite feature is the implementation vertical tabs, without the use of extensions. Some legacy extensions are maintained and can be found here: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master... (although you will need to use xiaoxiaoflood's userChrome.js loader AFAIK). Honorable mention goes to the Firefox CSS Store, which can be foun

Personally I've found https://github.com/xiaoxiaoflood/firefox-scripts/tree/master... very nice and almost indispensable – working versions of DownThemAll [1] and Norwell History Tools hacked to continue running on modern Firefox. [1] Yes, by now there's an official Webextension version of DownThemAll around again, too, but that's too much hobbled by the limitations of the Webextension API, i.e. can't download to outside of the official Downloads directory, can't intelligently/properly handle file name conflicts with already existing files [2], etc. [2] Most importantly, the Webextension API doesn't seem to have a "skip the download if the file already exists" option – it's only overwrite, rename the new download, or prompt, and Firefox doesn't even support the "prompt" option.

And history is equally bad. Internally the browser stores each individual visit to a page, and also the full history trail in case you clicked on links, but the built-in UI only shows the last visit for each URL and nothing else. Additionally, when I do a history search, there's no way to jump from a search result back to the chronological view (though as soon as I open the result, the chronological view becomes useless anyway because it only shows the most recent visit, which after opening the page becomes of course "right now"). The problem is that quite often I might not remember the exact search terms to find a page again in my history, but can remember and find some other pages I know I visited beforehand/afterwards/etc. If I had the full chronological visit history (plus access to the link trail if necessary), I could just look thro

It's quite a rickety process ever since XBL was removed in 72. This repository is usually the preferred base if you're interested though https://github.com/xiaoxiaoflood/firefox-scripts

They didn't just broke them by necessity of rewriting the browser, though – they then actively blocked them on regular browser versions (non-Nightly/Developer Edition/etc.). Case in point: With some limited maintenance and a compatibility shim for loading them, a number of old add-ons are still working on current Firefox versions: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master...

If you're interested, DownThemAll has been ported to support newer Gecko versions: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master... Waterfox G3+ supports installing bootstrapped/XPCOM extensions :-)

For things you use regularly enough I agree, but history eventually expires. Also the default history UI is rubbish about surfacing connections between pages – when searching history, you can't get the browser to take you from the search result back to that actual point in your browsing history that search result is coming from, then then browser only shows you the last visit of each URL anyway even though internally it stores older visits, too, and it doesn't allow you to see connections between pages (I opened that link from this page etc.). So if you know the right keywords to directly find a page again it's fine, but if you only know that before (or after) visiting that page you visited a different page, and you can only find that different page in your history you're sort of stuck. As usual, the best extension for dealing with that p
