I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

I am using Mozilla Firefox 64-bit with version 107.0 on Windows 10 21H2. I connect very often to HTTPS websites without a valid certificate. Often with certificates issued by themselves. Before it was always enough to say "I trust this website" once. Now the question comes again and again, whenever I connect. What could be the cause of this?

20 GB RAM usage, pagefile takes up all space on C: - 300 tabs in Tree Tabs

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,

Peter B. (I'm PC enthusiast)

When on youtube or any video website, when I click the PiP button on the side of the video, instead of having the video popup on the screen I have a new windows (only visible in the windows taskbar) which is invisible.

If I try to hover the (empty) preview in windows, it should hide everything else and show the window, but nothing happens as if the popup create a window but stops in the middle.

I tried with Firefox (v107.0 64-bit) and Firefox dev edition (v108.0b6 64-bit), same problem. I tried disabling every addon/theme, same problem. I tried disabling hardware acceleration, same problem. I tried Troubleshoot mode, works correctly.

Before re-installing Windows it worked normally. What could be the problem ?

Hello there! I have a strange issue where only the URL changes when I press the back button, it seems to happen randomly, but it isn't only happening to me, I was in a discord call yesterday when I saw it happen for my friend too. See attached gif for an example. Any idea what could cause this, or how to fix it? I haven't found any other threads about this, but I haven't looked very hard.

From time to time when maximising the Firefox window, the top 20-80 pixels or so are replaced with a white bar.

It is usually possible to grab the window by clicking somewhere next to the address field, and thereby move the window downwards, alt double clicking there which set the window to "not full screen".


Right-click in any of the "white" areas - which is located inside the FF window - opens the Windows desktop menu.

screenshot 1 - "not full screen" (all is fine) screenshot 2 - FF in full screen mode (title bar vanished - replaced by white space) screenshot 6 - right-click in white space opens Windows desktop menu

Found a few reports that seem similar but not identical to this one. Rebooting the computer usually helps but after a while the problem returns. It is a rather old machine, and quite possible that this is not caused by FF, however, only FF suffers from this behaviour - any other application works "normally" (i.e. you see the title bar and buttons when the window is maximised).

Try: https://www.youtube.com/watch?v=0fiVciCs8zU which ironically won't play in private! Every time you press the play button you get about half a second of play before pausing. In standard mode it plays just fine.

I'm on macOS's Firefox Developer Edition 108.0b3 right now (arm64/M1 CPU). Though my current version is a bit outdated, this problem appeared several months ago and still bothers me to this day.

When I, or any another application, opens a new link in Firefox, the browser _doesn't initiate the request_. So the address bar changes, new tab opens, but absolutely nothing happens afterwards, I'm just getting blank page. In order to get site opened, I have to click the address bar and press enter. Rarely, even that does not help and I have to press enter one more time again. The same applies to the basic links too - on this support website I practically had to click every link twice to get it opened. The click even is clearly registered: I see the :active state for a second. But afterwards, nothing happens, just like event got canceled in browser (clearly not JS error since it not only happens with links). It doesn't matter which site I'm using, where I am (even start page has this bug), and don't really seem to be connected to the extensions I'm using (recently I had high RAM usage by extension, and being unable to determine which extension uses RAM I disabled most of the untrusted extensions, which do not have cup icon given by Mozilla or not very popular), so I practically use _mostly_ clean Firefox now.

Before going full reset, I wonder if anyone happen to have the same issue?
