Firefox Support Forum

Unable to download jpg file complete. Get error message and image down will have .part after filename.jpg. DeepDreamGenerator.com site from user 'file manager' view. Can download ok if I right click image to show in new tab. Cannot find adblocker to disable which was DDG Team suggested was happening. I can download from file view in MS browser. Problem started after latest update.

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 on Firefox version 102. It assures me I am up to date. My credit union insists I must be on version 107 to log in. I was able to download and install version 107, but it gives me a different icon and none of my bookmarks are there. It is like I installed it new rather than upgraded. I have no bookmarks, setting, etc.

YouTube videos not working with Firefox since recent updates. Videos start to load but don't don't complete. Firefox is the only browser with this issue. Have tried three other browsers without issue.

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,

-- Windows 7 Ultimate SP1 64 bit Firefox 106.0.5 (latest autoupdated) no firewall nor any antivirus - since 20 years with no infection ... AMD FX-6350 Six-core ASUS M5A99FX PRO R2.0 24 GB DDR3 1600 MHz Sapphire Radeon HD 5750 1GB (AMD Catalyst 15.11.1, Nov 18, 2015)

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?

I'm porting a chrome extension to firefox: it clearly loads on the page as I see some of it working. But other things are not happening. There are no errors in either the page or the background page. So I wanted to set a breakpoint in my content page, and I followed the instruction on this page: https://extensionworkshop.com/documentation/develop/debugging/#debugging-content-scripts Which clearly shows extensions icons in the Sources/Main Thread.

But for me, there are none. The first screenshot is from the page where the extension is loaded no extension is listed, the second is from the background page for the temporary extension.

Upon restart, Firefox has kept dropping (not loading) hundreds of tabs. 555 tabs, as also listed in my sessionstore, but after loading is finished, only about 330 is actually loaded of those. Previously, there have been similar issues with different sets, and loading the full set over, and over again, sometimes the full set or very close to the full set is loaded, indeed. But it is clear that there's a bug or at least a very inconsistent behaviour in the code somewhere. How can this be propely troubleshot and fixed? Happy to help. Thanks.

I can't open amazon.com. I've disabled my antivirus and have tried in 'troubleshoot' mode. I have cleared my cache. I have flushed my DNS. It's been going on for days. I keep timing out. Other sites do not exhibit problems. Chrome DOES open amazon.com quickly.

having lots of problems with watching videos on youtube sound breaking up and videos stoping been having this since it updated ok on microsoft edge browser no prob but would rather use firefox than windows shit

After the second to the last update to Firefox I started experiencing an information pop up message "Could not determine any profile running in backgroundtask mode!".

Is there a fix for this?

Thank you.

Hi,

with a lot of effort I edited three times all my container entries at about:preferences#containers, but the changes were not overtaken correctly.

Now I want to start from the scratch without having to create a new Firefox profile. How can I delete the container entries permanently ? I already tried uninstalling and reinstalling the extension, but the entries were still there afterwards.

Thanks

I want to be able to use Firefox like I did before! Tired of having to re-log-in to programs that I didn't used to have to before I cleared cache, etc.

Hello, I somewhat recently noticed (maybe about a month ago) that my overflow menu disappeared and an "Extensions" menu appeared in its place.

I've already created a new profile and switched to it, with no success and I'm not sure what else to try or why it went away to begin with (and why this Extensions menu is now here and won't go away).

Any help would be greatly appreciated

When I do a search I need search result links that I click to remain purple so I have a record of where I’ve already been. This is no longer working instead the links stay blue. Please help: thank you in advance.

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 :)

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? :)
