When Mozilla releases the 90 apocalypse, at which point I will go to the 90esr- to at least avoid anything else untoward for a year - and since I understand that Mozilla, in its infinite wisdom, will be stripping out all the proton-disabled items in about:config, I'm wondering if anyone knows if carrying over those proton-disabled prefs in my 89 user.js to the 90 (which does currently register all of them) will continue to work if saved to the 90, i.e., if they will still be able to override the disastrous proton UI? That is, unless I have this all wrong, thinking that a user.js is supposed to be able to override prefs elsewhere.*

*Assuming Mozilla doesn't also completely remove the user.js in the 90.

Whether it's technically support or not, would still appreciate an answer.

Thank you

The browser.proton.enabled pref is still usable in Firefox 90.

I read that prefs like browser.proton.places-tooltip.enabled will eventually be removed and browser.proton.enabled will be used instead.

Thanks for that, if that holds, that will be a huge relief.

Thanks again morat.

Understood, should still be able to disable the proton UI in the upcoming 90, which is excellent news, but still curious to know if what I originally proposed - moving the user.js with everything proton there disabled in the 89 over to the new 90 - would in fact actually work if Mozilla stripped out all those about:config prefs to disable the proton UI?

If the devs removed a pref in the source, then the same pref in the user.js file won't do anything. It won't even cause an error. The app doesn't check if the prefs in the user.js file are obsolete.

Basically what I was thinking when I thought it over. If the pref no longer exists, then nothing for the user.js to override and replace.

Uh oh, I had it wrong that the 90 was the next esr version. Looks like it's the 91, not the 90 that loses the proton prefs. Meaning the next esr will be 91, with no way to disable the proton UI. This means that I will basically be in deep shit with the next esr when the 78 goes EOL. At that point, no way to avoid the catastrophic proton UI - at least not by way of about:config. (Currently, the 89 with various CSS and proton disabled - 99% imported from the 78esr - is all good, and was counting on simply moving the 89 profile over to the 90. Tested already with 90 beta.)

Firefox 91 will drop disabling Proton. This includes removal of the currently available "Proton" preferences and @media (-moz-proton) @media not (-moz-proton) rules.
