Firefox Support Forum

I have been using Firefox for over a decade. My doctors systems use MyChart for communication with patients. All of a sudden, it takes minutes to load ANY and EVERY page. Their IT says it is Firefox is not compatible with MyChart. Why all of a sudden is it not compatible??? I don't want to use Edge or Chrome....especially edge.

Prompting window for primary password failed to show up after this upgrade.

1. when I opened Firefox, it did not show up. 2. when I opened about:logins, it did not show up but alerted that I should enter primary password to access passwords. There was a "Log in" button after the alert, but nothing happened after I clicked that. 3. I can't access any of my password unless I remove Primary password.

Any idea?

Windows 11 system info:

Edition Windows 11 Pro Version 23H2 Installed on ‎17/‎06/‎2023 OS build 22631.3672 Experience Windows Feature Experience Pack 1000.22700.1009.0

I get the message: "Uh oh, we couldn't load this page at the moment. Thank you for your patience as we work on this. Please try going back to the home page or logging out" when trying to login to a patient portal site. I have previously logged into this site on numerous occasions and I can login using Safari. I've cleared the cache, cookies and history, rebooted Firefox and even threw in a few chants for good measure - nothing helped! I've not changed settings recently either. I'm at a loss, can you please help? Thank you, Edouard Cantin.

For several months I have been experiencing very frequent tab crashes and overall freezes in Firefox. I have tried removing all extensions and starting in safe mode, but nothing has solved it. I have reinstalled Firefox and updated all of my drivers. There doesn't seem to be any pattern to what causes the crashes and freezes. They can happen any time and on any website. They happen around 5 times an hour. I do not know how to troubleshoot any further.

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

Didn't have this problem before but after a couple days ago, I didn't know what changes happened to my computer but most of the program wouldn't work except I have to run it as administrator. The download problem occurred when suddenly my FF always froze no matter if I closed it or not. So I just refresh my FF and copy my profile from the old backup data that FF generated and just pasted all of them on my new profile. The problem is that after I tries to download warcraft 3 maps from google drive, the download always occurs as failed. I don't have this problem when I tried it with Edge. Running FF as admin doesn't worked either. Neither as when I run FF as refresh without any extension. Downloading stuffs with IDM (Internet Download Manager) does not have any problems. Just now, I try to download a .xlsx files from my workplace websites. After I click on the download or the file itself, nothing occurs as if nothing happened. This is giving me a headaches so I came here to give it a try if anyone can help me fix this problem.

Hello,

I am experiencing an issue related to the Vanguard anti-cheat system used by Riot Games, specifically in relation to League of Legends. After installing the game and Vanguard, I am unable to open Firefox. When I try to launch Firefox, nothing happens. However, if I change the name of the firefox.exe file, I can start Firefox on a different profile, but it only works for a short period before becoming unresponsive. None of the options or tabs respond after that.

Could you please provide assistance on how to resolve this issue?

Thank you.

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine

When using amazon the login and page load times are excessively long. More often than not I can open MSN, load amazon, login, and find what I'm looking for before Firefox has completed signing me in or searching for an item. This is not a once in a while problem, it happens every time with amazon, some times worse than other times. Ive deleted and reloaded Firefox, cleared all history and tried as many other things that I could find online to try, none of which helped.

When ever I play a game, the video I have playing (yes I need that stimulation) all of a sudden just freezes I can hear the audio but the video just freezes unless I click back onto the browser

Every time I attempt to download a file today, no matter what it is or where it's from, it pops up saying that the download failed immediately. I can download through Edge or other browsers, just not Firefox (or any Firefox offshoots like LibreWolf). Not sure what's causing it, I've run a whole gambit of troubleshooting options, including:

• Checking my connection
• Checking my drive's space (plenty)
• Changing the download path
• Reset the download folder in about:config
• Rebooting my computer
• Clearing my downloads
• Trying a new profile
• Run a MalwareBytes scan
• Closed MalwareBytes and turned off my firewall
• Ensured OneDrive is disabled
• Refreshed Firefox
• Did a clean install

Nothing works. The only thing I found that gives me any kind of clue is this error message in my about:support: ""NotAllowedError: Could not create unique file in `C:\Users\[my name redacted]\AppData\Local\Temp' (NS_ERROR_FILE_ACCESS_DENIED"" It seems like Firefox is trying to write to Temp and can't get the permissions, but I'm not sure why that would be or how to fix it. I have tried googling my butt off, but I'm not finding anything helpful - I may just be blind.

If anyone has any idea how to fix this, it'd be much appreciated!

i updated my browser and now everything is gone, my extentions wont open as its in "safe mode", none of my browsing history is saved anymore. should I delete firefox and reinstall it?

Dear Firefox support community

Greetings from southern Germany, near Lake Constance :-)

I have issues since a few months that Firefox loads website only when I actively click on the app and put in foreground. Then the tabs start loading. Why is that?

After startup of Windows 10, I usually run a little batch script of mine starting various applications such as Outlook, Notepad++ etc, including Firefox along with my favourite websites, just like this:

start "" "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" https://de.wikipedia.org https://www.google.de [and more...]

So Firefox loads and opens all the tabs in the background, while other apps such as Outlook or Notepad++ come in the foreground. I read mails etc. before I decide to check e.g. Wikipedia. So it might take 5 minutes after Firefox got opened before I actively put it in the foreground. THEN I see no websites got loaded, and THEN Firefox starts to load the websites, which then takes the normal amount of time of a few seconds.

I wonder why Firefox does not load all my requested websites directly after start in the background.

An annoying side effect is, when still in Outlook and clicking on a website link in an email, it won't open in Firefox, most likely due to that reason that Firefox still waits for all the other websites to load. I need to put it into foreground, wait for the loading process to complete, and then go back to the email and click on the link again.

Any ideas would be greatly appreciated!

Many thanks in advance for your assistance & Best regards Volker

After update to 126.0.1 I cant access two of the four windows that are open. They are still listed under the Window toolbar option but clicking on them reveals nothing, as if hidden except they are not in the Mac toolbar. Not sure if this is a new feature or glitch, any help would be great, the two windows I can't currently access contain alot of tabs I need.

I have used Firefox exclusively for years. I use Hushmail but recently I am missing the respond to email bar that was always there. I have to use Edge and Chrome (but not a fan of) and Hushmail works like it used to. Something about Firefox must be the difference. Can you help me?

I refreshed Firefox last night. Now, Facebook doesn't display images--it displays about half; the rest are blank boxes. Facebook closes while I'm typing. A game I've been playing freezes and I have to close it and re-open it. Telus email seems to be fine. My Google results are in massive type and I can't adjust it.

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Thanks.

Firefox 126.0.1 Mac OS Sonoma 14.5

Everytime I select Firefox-Settings.. the Settings window opens and then crashes

This crashes with Troubleshoot mode selected

Partial crash report included below.

After rebooting a Windows 10 computer, and starting Firefox, two Firefox Windows open. The second one opens Yahoo on it's Tab with no other Tabs open. Before booting, there was only one Firefox window open. This has happened before in the past.

Could this be fixed.

I have also reported several times that at times, Bookmark folders are found missing but found in strange places where I did NOT move them. I have been told that this could be possibly caused because of my very large Bookmark file. It would be very nice if this was resolved. I have reported this at bugzilla.mozilla.org.
