Yes! FF PMs and designers seem to HATE user customization, add-ons and power user capabilities yet those are the main reasons I came to FF and why I still use it. While FF is still the best browser for me (barely), it's only achieved this by all the alternatives enshittifying and dumb-ifying their browsers even faster than FF. As it is I have to spend significant effort under the hood customizing UserChrome scripts just to maintain minimal usability. (...and thank the heavens for Lepton (https://github.com/black7375/Firefox-UI-Fix), a regularly maintained, well-curated, all-in-one collection of essential Firefox fixes (which can each be turned off individually via flags.)
Firefox has enshittified itself if your reference point is the original Firefox of the early 2000s that unseated Internet Explorer's dominance. User customization has steadily eroded since version 4 when they started copying Chrome, from multi-process to removing the statusbar to introducing the hamburger menu to the insane practice of incrementing major version numbers into the triple digits.

Give Pale Moon a try and ignore the FF fanboy propaganda of it being oLd aNd iNSeCuRe. It isn't, it's regularly updated to keep up with Google dominated web standards and security patches, and runs on an independent fork of Firefox's Gecko rendering engine. It is not a mere rebuild like Librewolf, Waterfox etc but a separate browser that retains all the full customizabiity of pre 2017 Firefox with full XUL extension and NPAPI plugin support.
