Firefox Support Forum

Hello this is Don. I am using Win10 with Firefox 120.0 64 Bit as my default browser I am having a problem with logging in to The Sony Community Forum where I help Sony users. I enter my email as my Sign in ID then press enter to get to the password screen and it goes to the spinning grey circle on a white screen. My Memory and CPU gets really high and my browser locks up and I have to go to task manager and End Task for all Firefox processes to unlock it. I have no problem getting in to the website with MS Edge but I hate using it but I have to in order to sign in to Sony Community Forum and help users. I have have done a full system scan for malware with Norton, MSERT, Malwarebytes and Windows Defender. I have done a REFRESH of Firefox and I have even uninstalled and re-installed Firefox and nothing helps. I have it set to auto clear everything under History including Cache and Cookies. There is something about this Forum that for the past week will not let me in. I have emailed my Sony Advocacy leader and he is having the Web Site Team looking into it. This is the only website I cannot log in to. I have used Firefox for years and do not want to have to go to something else.

Respectfully, Don

When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

Yo, Linux sysadmin here and been using Firefox forever.  Surprisingly I have this ancient 12 year old System76 laptop that I use for nearly everything (got a newer Lenovo that I been meaning to switch to but no time).

Using Debian 12/13 with Gnome 43.6/X11.  Can't quite figure out this issue though.  Besides being a sysadmin, can have other side jobs/projects going on as well, so can have 5-10 windows open in different workspaces, sometimes with hundreds of tabs all together (big fan of the Auto Tab Discard add-on and about:memory Minimize Memory Usage to keep performance up and resource usage low).

Been noticing this issue for the last few versions where suddenly, after random amount of Firefox uptime (can be after days of perfect performance) my keyboard input aka typing gets extremely laggy, like 30 seconds behind for all keystrokes, except: Ctrl-F instantly brings up the Find in Page bar, and Ctrl-C instantly copies to clipboard.  Ctrl-V, however, 30 seconds lag, Ctrl-A also....  Mouse is fine though and can right-click and paste instantly or use other menu options.  Happens anywhere in Firefox too: in address bar, in the find text box, in the preferences, in my saved passwords, haven't found a place with no lag.

Have searched around for some hours now and only found suggestions to disable accessibility service, but accessibility service has already been disabled for a while now.  Everything else in my Gnome desktop session is running fine.  Restarting Firefox temporarily solves the issue but is highly annoying and interruptive with as much as I have going on sometimes.  Due to timing randomness, starting Firefox without certain add-ons is impossible as I can't spend days at a time without any of them.  Just have to open a text editor and type what I need to in there, then paste with mouse, until I can find a good stopping place to restart Firefox.

Have included most of the info from about:support in the Troubleshooting Information.  Spent quite a bit of time looking at all my modified preferences, nothing popped out but if there's something you think I could include to help, let me know. Thanks

Why is when I leave multiple windows open with multiple open in the windows, the next I go to look for the window it's closed. Sometimes it happens when Windows updates, sometimes it doesn't.

Why I'm asking this question here is ridiculous! I never get an answer. Anybody else had a issue with this? Is there a Browser that doesn't do this, I'm fed with FireFox!!

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

When I have to change a setting on my LAN printer, an HP, I should be able to access its built-in settings module. Firefox will not let me access the printer because it doesn't have a trusted certificate.

So I get a blank page with the message: "we could not verify the certificate: reason = untrusted" and doesn't give me any options. In versions past, I recall an option to connect anyway if I trusted the site.

If there is a setting that lets me enable the option to continue anyway, where is it? Alternately, is there an exception list, perhaps by IP address, that will allow the browser to connect? Perhaps another solution?

I can't be the only one who is encountering this issue.

Thanks,

Ed

I have used Firfox for many years as my main browser...I just upgraded to Sonoma on two Macs and Firefox is nu-useable on both... I waited for the new update and somethings were working but still can not depend on the browser to work... Can you help...?

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

Most recent crash report ID: bp-bd37576c-c5ef-419f-a031-fe1910231123

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.

I'm using Firefox 120.0 on an iMac running OS 13.6.1. When browsing in an open window, merely moving my iMouse (no clicking) causes the display to zoom in and enlarge the display a huge amount that is much larger than normal zooming can produce. Please provide a solution.

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

At first Firefox opened and then immediately closed. Then it simply wouldn't open. I uninstalled it. Changed my profile (as per a suggestion in Support I read about). Reinstalled it. It opens now in "safe/troubleshoot" mode for a few moments. I checked the crash report and there are no current crash reports which might help me with the problem. I can't log back in as it keeps closing after I enter username and try to enter password - i don't think its a password issue - it closes all the time even at other places. I'm at my wits end and don't want to abandon Firefox. Any thoughts appreciated. Many thanks, A

Hi,

I lost all my bookmarks because I forgot my Firefox account password and didn't realize they were in the cloud (I thought they were stored locally). I don't have any bookmarks backups, but I did recently back up my Macbook via Time Machine. Would Time Machine be able to recover my previous bookmarks? If so, how?

Thank you.

Dear Support Team,

I always receive popup messages when trying to play a youtube video. "Ablockers not allowed". But I haven´t installed any adblocker. I am not sure, but I think this erreor occurs since the last Firefox update (?). Had never before this error. See file attached (in German).

I am using Windows 10.

Thank you in advance for your help ! Best regards Chris

Hello, from Terminal Servers, it is not possible to browse the Internet via FortiGate's explicit proxy from the Firefox browser, while there is no problem with Chrome or Edge. When the user tries to browse external sites, the proxy sends the error page "You need to authenticate to use this service". It seems that Firefox does not pass user authentication to FortiGate. The proxy authenticates users per session via Kerberos tickets.

Firefox version: 115.5.0esr

I also performed the following settings to pass the Kerberos ticket to the proxy without success: https://people.redhat.com/mikeb/negotiate/

I also noticed that it is not possible to change the "network.negotiate-auth.allow-proxies" setting from "false" to "true." Is this my problem? Is it normal that it cannot be changed?

Attached are the settings.

Thank you in advance.

Firefox hangs when I try to maximise the window. If the firefox window is covering half of my screen and I try to maximise by clicking on the window button at the top right, it hangs. I get a message "firefox is not responding, wait or exit." Then I have to select close, and start it again to work. This happens occasionally, once in every 2-3 days.

On the first load of the day FF partially loads a page then freezes that page. Links are dead and can't type into any text field. This will happen with multiple tabs then suddenly everything starts to work with no further issues. Note: the browser does not freeze.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD
