Haha, it doesn't work like that. There is a VAST amount of prefs being added and removed in each and every new release of Firefox, even more so on the Nightly branch. It's impossible to document a list of pref changes.

You shouldn't need to sort by date to know what pref you want to configure. You should get in and out of about:config quickly. What exactly are you trying to achieve?

What exactly are you trying to achieve?

There's a new white screen with a "loading flower" showing up sometimes when I click on an idle tab. It's probably a "tab discarding" feature (which is totally new for Firefox, but has been on Chrome for some time). I wish to disable that.

Not that know of I have never seen and you are the 1st to mention this. I would think it maybe malware 1st before Firefox put a flower on. My system rocks so if there was a flower I would never see it if is fast.

Is sorta the grey circle that gets bigger to completion while a Tab loads but not for discard that I have seen. If it is this your talking about it is only a bother if slow system/internet I would guess. No, do not know what it is called.

No, I'm not talking about the loading circle before loading a page. I'm talking about a flower like loading white screen that sometimes shows up when I click on an idle tab. It is a tab discarding function as it was never present on previous versions of Firefox.

Hello, [...]

Solved! Solution here: https://support.mozilla.org/pt-BR/questions/1187472

Solution: You need to create a userContent.css to change that white flash to a dark gray / almost black. This also changes the color of the brief white flash before a page loads. Perfect for night. Go to about:support in your Firefox browser, click the button labeled "Open folder" in the Profile Directory section. A new Explorer window will open, now create a chrome folder and inside that folder, create a new text document labeled userChrome.css not .css.txt. You may need to enable the File extensions type to be shown via the View panel under Show/hide section. Open the newly created .css file and paste this into it, save it, close it, restart Firefox. .tabbrowser-tabbox { background-color: #a9a9a9 !important; }

That was very good work. Well done.
