Firefox Support Forum

Problem I had two versions of Firefox open. Window "A" (my primary window) had many open tabs. Window "B" had only three tabs open. Like a knucklehead I accidentally closed the wrong window, "A". Upon restarting only the "B" version was there.

Possible Solution Two days ago I cloned my "C" drive as a backup. Although the Profile folder on the backup will only have 90+% of the tabs - I can gratefully live with that. I just need to know what files to copy over from the backup drive Profile folder to the messed up drive's Profile folder. I am hoping it will be that easy and I can copy the tab files and not the entire Profile folder. Thanks.

Previously visited links of eBay items are not showing up in "purple". eBay has increased the length of those links beyond 255 characters which seems to have triggered this issue. I can click one item on a listing search page and it will be purple as long as I open a second tab when opening it. But when reloading the same list, the same item is not purple as they always used to be. Actually, a few still are, and those have the shorter URL. The links do show in the history record. This is very annoying, I can't imagine I am the only one who is finding this. It has persisted through the last two updates. This needs to be fixed.

First, this post is basically Congratulations for Firefox upon working almost flowlessly under this extreme heavy load without crashing. Saving/loading sessions works well. (which is unexpected but makes me _very_ happy :-)) Firefox exits properly without any exceptions, no matter how long it runs, or how many times the PC is sent to STR mode meanwhile.

Second, everything is fine, except RAM usage. No matter how many RAM is installed, Firefox takes up all of it after a few days of normal operation. I have recently upgraded my PC from 16 to 24 GB of RAM only for this sole reason to see if anything changes, but it did not produce any noticable change, except that it takes 5-7 days for Firefox to fill up all the RAM instead of the 3-4 days before. Disk space on C: drive was nullified by Firefox as the paging file went up to 50 GB.

I want to hunt down this thing. I have approx. 300 tabs, 2 addons, and Hardware Acceleration is disabled since otherwise Fox hangs several times a day (have to be killed from outside). Pics are attached. https://addons.mozilla.org/hu/firefox/addon/tree-tabs/ https://gitlab.com/kroppy/TreeTabs

I'd like to get suggestions where to start.

1. Disabling or replacing the adblocker ?
2. Inspecting memory usage on Process Manager (about:processes) and Task Manager (about:performance) pages ?
3. Installing some external tools like Firemin ?

Please don't suggest neither safe mode nor disabling all addons, since that makes it impossible to reproduce this amount of load, which is the primary reason behind the symptom.

I PrtScr'ed Process Manager and Task Manager, see that RAM sizes per page are normal in Task Manager, but not in Process Manager (10 times more).

CPU usage is totally normal for this load, even when memory is in the heaven. See the TaskMan pic. (I suppose that's because of ad blocking)

Thanks for any ideas,

Twitter Video Streaming in Firefox on an older computer (Windows 7) does not work. The videos don't play (just audio). I logged into my same Twitter account on Chrome on the same computer and Twitter video streaming worked perfectly. Please fix the disparity.

Everytime I try to close my Firefox browser window, it just stops. There are multiple processes taking in excess of 200 or 300K in memory that seem to be causing the problem. I have to manually end the process just to close Firefox, and it is quite annoying.

I just checked, my Firefox is up to date. Yesterday I deleted and re-installed Firefox, but it's still doing the same thing.

This is kind of driving me nuts to be honest. I have Chrome, Opera, and Edge also installed on my computer so I'm ready to jetisson Firefox but thought I'd see what the community has to say first.
