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
