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)

I am currently having problems with my Firefox browser. For example often if I type something into the google search box at the right of the address bar and hit return nothing happens until I go down and select Bing instead of the google setting. Also in hotmail (I am on a desktop) if I go to reply, the original is now ether twice. This does not happen if I use Google browser. But I prefer Firefox as I have used it for years.

My concern is if I delete Firefox and reinstall it, I may lose some of the settings or bookmarks that I have set over the years.

Any suggestions? Please simple as i am old and not computer savvy.

Your help would be so appreciated. I am currently on Firefox 107.0 (64 bit)

Thanks, Anthony

After moving to Firefox 91.9.1esr I found problem with System theme 1.2. The color of tab add button was changed, and the button is not visible with my Windows 7 classic windows system theme. So, I'm trying to find a way to port System theme 1.0 color scheme to newer firefox versions.

Creation of a simple theme with firefox color extension works. But it is unable to recreate the effects related to active and inactive window color changes. As, I had to use bitmap to get the OS blue color transition pattern.

It seems the system theme is stored in omni.ja file. Modification of the omni.ja seems to be not a practical solution. So, it would be a better way to create an addon theme with the same code as the System Theme 1.0.

The first question is, if it will be possible to create a theme with the same code as a system theme has. Will it be able to perform the same way?

The next question is: Where the source code of the system theme is? I was unable to find it in the Firefox source. It seems, it is not stored in any obvious location.

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.

Hello :)

I'm using Firefox 107.0 on macOS 12.6.1 and I'm having weird issues with the displayed font. It appears on the startup screen of Firefox and on websites (see screenshots attached).

The garbled font is called ".SF NS".

I've tried turning the option "Allow pages to choose their own fonts, instead of your selections above" on and off without success.

I have also tried enabling and disabling hardware acceleration - also without luck.

The issue does **not** appear in safe mode. Unfortunately resetting the theme and disabling all extensions hasn't helped either :(

I have also downloaded and installed a font called "SFNS Display" but the issue persists.

Uninstalling Firefox (with AppCleaner) and reinstalling hasn't fixed the problem.

I don't know what else to try. Can someone help me please? :)

I have a recent problem with mouse hover with Bookmarks in the Menu bar. Basically; it no longer shows the URL info in the drop down box, only a blank, box appears. I am using Windows 7 and the current Firefox 107.0. It appears to be a Windows 7 issue, because I have the same problem on my Win 7 desktop and Win 7 laptop, but a laptop with Windows 11 is OK.

The really odd part is this. If I run Firefox in troubleshooting mode in either Win 7 machine, the problem goes away, and the drop down box works fine, and displays the URL info. If I manually disable my add-ons in normal mode on either machine however, the problem does NOT go away.

One last odd point. On my desktop, when I am in normal Firefox mode, and look at Bookmarks in the History tab from the menu bar, the last (bottom most) bookmark, and ONLY the last bookmark WILL display the box info correctly. On my Win 7 laptop the same effect occurs, but the last (bottom most), bookmark will sometimes work properly in other folders, such as Other bookmarks for instance.

Also; the URL box does work properly with the ‘Show your bookmarks’ button, and the bookmarks menu if I use the “Open application menu”. These options produce too much ‘white space’ however, and are not as convenient to use. The drop down box works fine with other browsers, but Firefox is my favorite browser. I have searched the Internet and the forum, and not found a similar problem.

Attached are two photos showing the result in normal and troubleshooting mode. Thank you in advance.

Hello! Sites like Gartic Phone and Whiteboard Fox do not respond to my Huion tablet pen. I don't think Firefox recognizes the pen as a drawing device.

I have done some troubleshooting and have figured out that this is a Firefox specific issue: Google Chrome and Microsoft Edge both respond to my pen on those sites. I saw another person was struggling with this exact same issue, but the thread was archived with no response.

How do I fix this? Was there something I missed in the settings?
