is there a complete list of config entries?

more options

today i created a new profile to FF to start over. i noticed that some config settings i set a few years ago (and kept them with each upgrade) no longer work/exist. FF seems to somehow kept them in his "memory" and they working fine. i tried to create them manually but FF doesn't recognize them.

these are the config entries in question: browser.tabs.animate browser.fullscreen.animate

so i want to know if there is a complete list by Mozilla of all config entries so i can take a look.

Did you toggle toolkit.cosmeticAnimations.enabled to false on the about:config page like I posted above?

No. There is no complete list. Such a list would be unmaintainable because of constant changes and differences between Firefox versions. Some prefs are hidden and appear only when you create them yourself.


A lot of animation prefs have been moved to one single pref named toolkit.cosmeticAnimations.enabled that covers them all.

The list in about:config is fairly complete, but of course, without detailed explanations.

The source code file which has a lot of the preferences also is light on the explanations:

https://dxr.mozilla.org/mozilla-release/source/modules/libpref/init/all.js

The mozillaZine Knowledge Base has articles on a lot of longstanding preferences.

I generally throw the preference name into a search engine when I need to learn more about it. If that doesn't work, then I'll try the source code site.

oh ok, i understand.

and i liked the "browser.tabs.animate" because of the animation when i create a new tab. i have a rather old and slow pc and more animations, mean slower response.

O.M.G you're a lifesaver. i looked at the source page but it's too long and i don't understand most of them or they aren't obvious.

i googled about "toolkit.cosmeticAnimations.enabled" and i saw some nice stuff. https://bugzilla.mozilla.org/show_bug.cgi?id=1366060#c3

thank you :D
