I followed instruction several time to uninstall and reload fresh and Firefox will not run, except in safe mode. This issue has happened once before and I solved it by reloading it fresh but this time I cannot get it to run.

Hello,

Recently I was forced to install some "stuff" on my work laptop. Unfortunately, I am not quite sure what they installed. I have contacted my IT department and all I've gotten in response is that "we haven't blocked any browser or sites."

Since this update, I find that Gmail will eventually show an error and when I go to refresh the page, the loading screen never completes. Additionally, Youtube will eventually declare that I have no connection and at that point I can no longer open new browser tabs.

I have updated Firefox, used troubleshooting mode, removed extensions, turned off ad blockers (uBlock Origin), and nothing seems to work—these issues always appear again eventually.

I would greatly prefer to not use Chrome, so if there is anything I can do to fix these issues I would be all ears to know what it is.

Thank you, John

At random, whenever use a search box on a page, Firefox will lock up. The "loading" icon on the tab will animate as normal, but the entire window won't respond. If I press the show desktop button and then try to reveal Firefox, none of the windows will appear. I'd have to go into Windows Task Manager and be lucky enough to terminate the correct process containing the tab, or else I'd have to start all over again.

If you visit a website frequently and want to wipe delete a website from your historical record, Firefox blocks on the UI thread to do this.

In my experience, depending on how often the site is visited, the single thread on a processor can be pegged for many minutes, consuming gigabytes of memory.

If this is not a bug, then it is a very poor user experience. I was only able to resume after terminating the application in Task Manager.

Version 100.0.2. Desktop. Windows 10.

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

I cannot open OneDrive with Firefox. I tested Safari and Chrome to see if they have the same problem. They both were able to open OneDrive. The only Firefox extensions I have are Adblocker Ultimate and Print Friendly & PDF.

About two days ago the cursor started disappearing / flashing when browsing in Firefox. It does not mater where the cursor is placed on the screen either the arrow or the hand will flash when moving. My system is a windows pro 10 system with all updates, last updates for W10 were made a couple of weeks ago, on Firefox whenever it asks to upgrade I do it.

Specifically: 1. If the mouse is stationary there is no cursor, if I move it the cursor flashes. 2. When the system comes up and I launch Firefox all is OK for about 2 – 3 minutes then the flashing begins. 3. If I stop Firefox ie “X” it and restart it the flashing occurs within 0 – 30 seconds. 4. If I restart the PC steps 2 & 3 repeat.

I have two other PC’s Windows Home, and Windows 7, as well as a laptop with Windows Home all with Firefox 101.0.1 all up to date all do not have the above issue. This does not occur with any other programs. I have two monitors, tried Firefox on each makes no difference same problem.

I have tried searching the internet and all I find is about Caret which is off. I uninstalled Firefox and installed it. That made no difference.

Any assistance will be appreciated.

Thank You

The latest update for Wondows 10 prevents Firefox (and Edge) from loading. Everything works fine once I've uninstalled the latest update so the problem is clearly theirs. I can't be the only person experiencing this problem but contacting Microsoft is next to impossible. I wonder if you can: 1) alert them to this issue; and 2) pressure them to fix it as constantly uninstalling the updates is a pain!

Error message when accessing business websites which use Cloudflare: "ERROR 1005 ACCESS DENIED DUE TO ASN 9009". This seems to be because Firefox is using ip addresses which are blacklisted. This has been checked with blacklist services such as DroneBL. I am not using a VPN. I constantly clear cache & cookies from Firefox and then restart the computer. I am not ignorant or stupid. Why is Firefox using blacklisted ip addresses? Is it because of M247? Is there any way around this extremely annoying problem? Thank you for your response.

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

Solutions tried but unsuccessful: 1. Checked page size. It is correct at (80 x 297mm) 2. Cleared browsing history, cache, site settings, etc from start of time. 3. I have put print_resolution to 0 in about:config 4. I have put scaling to 1 in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 5. I have put shrink to true in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 6. I have alternated values (1 and 9) of paper_data in about:config (https://support.mozilla.org/en-US/questions/1297631) 7. Uninstalled ticket printer driver, rebooted PC and then installed again (Xprinter XP-80C). 8. Uninstalled Firefox completely, rebooted PC and downloaded again from Firefox website. 9. I have tested on a Laser A4 printer from Firefox on that same PC. Works fine. 10. Attached is the scanned picture of print from Firefox 100. Firefox 100 11. Another attached contains the scanned picture of print (correct one!) when I re-installed Firefox 64 link text

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

Hi.

Using Windows 10. Suddenly, Mozilla gives the "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window" message. I've tried all steps listed on the help site except reinstalling Windows 10, as the comment made said this would require reinstalling programs that did not come pre-installed on my PC, which I don't want to do if possible. I have uninstalled Mozilla, and the install stalls at about 70% with the aforementioned error message. Any help would be greatly appreciated! Thanks.

I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.

Hey, Twitch dosnt work for me (error #4000) and neither do Reddit videos. Pictures and Youtube works and I could not find a solution online. Thank you for providing this awsome browser. please keep fighting for privacy.

Dear Admin,

My firefox browser can't shown the correct myanmar unicode script when I type in google page and other websites also shown the wrongly font scripts that are unable to read. I'd asked to google and they said it is the font rendering problem and advice ask to your team for help. Please take a look and advice me how to fix it. I'd installed myanmar unicode font in browser and set as default. Other websites which are use Myanmar unicode are also shown the wrong script in firefox browser. The browser version is 103.0.1(64bit).

Thanks for your kind response, Htet Aung

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.
