Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

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)

Hello Firefox Support Staff,

I use Firefox on a Windows 10 desktop PC.

Firefox often crashes when I close the browser by clicking the X either at the top right or the tab.

Please let me know the type of information you need to debug.

Thanks, Sam

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.

firefox is my goto browser-tons of bookmarks etc-always kept UpToDate along with my dell MS10 laptop - today laptop boots up fine, outlook and MS edge work fine, but firefox will not start up, even in Administrator mode - searched for help - tried the run command firefox.exe -p, and also tried to create new profile ( as suggested ) that didnt work either- i would hate to uninstall and reinstall ! any help besides that ?

I have been a Firefox user for most of my time on a computer and that's a lot of years. A regular site I visit is Townhall.com. A few months ago I could no longer play videos because the link (video screen) would not appear. The text below where the screen should have been appears. I worked with Townhall on this and we could not solve it. Interesting was that periodically the link would appear but now doesn't appear at all. So I am forced to use MS Edge for Townhall videos.

Then it happened on another site I frequent - RacerX.com. When I try to play a video I get a blank screen with the message: "Unfortunately your Targeted Advertising privacy settings prevent us from showing you this YouTube Video. Please update your consent to see this content." I cannot find anything in settings which should cause this. I changed nothing. Settings are the same as they've been for years. So now for RacerX videos I have to use MS Edge.

I would prefer to continue to use Firefox as my browser but switching back and forth is not productive. As much as I do not want to make MS Edge my default browser it looks like I will have no choice unless you can help me solve this issue.

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

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?

Firefox On Linux Persists with a problem that many webpages that are useful,such as wikipedia,youtube or any others crash the browser because for no reason,it returns an error message saying that i have multiple tabs open when there are only 2 tabs shown at the screen at one time,is this normal? i found this out in 100.0.2 and no,some useful websites like troubleshooting or websites with multiple file links for example can still run like they normally would

Hello there. Ever since the latest update (to 115.0.2), I've been experiences random crashes. It's only happening with these 2 sites: https://www.mapsofworld.com/ and https://www.buongiorno.sk/ (there may be more but I haven't discovered any others as of yet). I open the sites and FF immediately shuts down. And then, after I restart it, there are no crashes listed in the logs (about:crashes). I've tried everything. Cookies, cache, a "refresh", a fresh install and I've also checked my system and HDD for errors but nothing helped. Any idea what I should do? The problem seems to be on your side, not mine

I've encountered a very weird behavior: when selecting where to save a file or selecting a file to upload, the browser hangs 100% of the time.

Even when I go to about:memory, click Load, the path selection window appears - regardless of whether I select a file or close the window, the browser hangs and the window stops responding. I tried waiting for several hours - to no avail. Only restarting helps. Same with the upload selection window - regardless of whether I selected a file to upload or closed the selection window, the browser hangs. Before freezing permanently, the mouse cursor stops moving, then lags around a bit before recovering.

I tried cleaning download history, cache, recreated profile, restarted without extensions, in safe mode, disabled antivirus - always the same result.

Please advise me, maybe someone has encountered something like this - I really don't want to start using Chrome. My OS is Windows 11. Thanks in advance.

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

I play a game at Vegas World. It's basically a free online slot machine site. I have played it for years with Chrome. Recently switched to Firefox. Playing an auto spin slot game, Firefox gets slow and hangs after about 25 spins. Chrome will go for 10,000 spins. So, Firefox is useless on game sites. I don't really expect a fix or solution. And I don't actually expect to use Firefox by the end of the day.

Recently my Firefox crashes sometimes when downloading a file for example from Yahoo mail. This is not happening always, but sometimes when downloading a file. I have the latest version of Firefox, Windows 10. I changed password, deleted cookies, did full virus scan, but the problem still persists. Is this an issue of the new version of Firefox and will be fixed with the new update of Firefox ? This is happening only with Firefox and not with other browsers.

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

Every day. Videos won't play. sometimes one restart of firefox will fix it. sometimes multiple restarts are required before it'll work. The loading bar at the bottom of the video (on the seek bar) indicates the video is loading but it won't play. There have been times where I have disabled every single add-on and it would not work. Add-ons do not seem to be the cause. I have tried it in a private browser window with no joy. I have refreshed firefox, I have uninstalled and reinstalled it. I have tried disabling my antivirus. I have tested videos on websites in other browsers with no issue. The issue seems to be with the video player itself. overlays seem unaffected, I can use the seek bar and it shows the captions. I have tested different websites including Youtube, Vimeo and Steam. I tried many tens of times to get it working today to no avail. finally when I closed nearly all my tabs, the video worked (but I had also opened TOR and run avideo in that), I am not sure if this is the cause. If the cause is having multiple tabs open, this is an issue for me. I have a learning disability and likely ADHD and I have a set of tabs as my homepages so I don't forget things. If It's not the mutliple tabs, then what else can I do?

On my laptop (121.0 on doze 10) I have no problems but on my desktop Firefox (121.0 on doze 10) started to struggle with Google a few months ago. Sometimes the Google site doesn't load, sometimes it loads but doesn't connect (no auto-complete, no search) and if it does work the result links often don't load when clicked. It's like Google falls asleep and then, when it wakes up, all is fine, until it nods off again. I have followed advice provided, cleared cache, cleared cookies, removed plugins and extensions, reinitiated and reinstalled. Running in safe mode seems to help, as in pages seem to load faster, but sadly does not eliminate the problems. Other browsers on this machine are not affected. No time sync issues.

Any suggestions?

TIA

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.
