Firefox Support Forum

K, so I've read numerous posts on trying to recover my bookmarks. Notta, zilch. Getting the usual messages when trying to import from the backups, etc. 15 backups and none are working. Anyone know how to trace what application Firefox refers to at launch regarding, "another application is using the file" message?

Thanks for reading.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

Hello, I cannot get videos to go into full screen in FF as they used to before latest update. Tested on various sites. There are no controls shown on YouTube unless i either hide the taskbar or scroll down both of which is a nuisance. On some sites the task bar stays at the bottom which it didn't used to do. link text

Hello Firefox Community,

I hope this message finds you well. I am reaching out regarding my website (Mazterizes), and I am keen to ensure its optimal performance and compatibility with the Firefox browser.

I have noticed "https not valid" when accessing my website through Firefox, and I would appreciate any insights or suggestions on how to address this issue. Additionally, I would like to ensure that my website adheres to best practices for compatibility with Firefox.

If anyone has experience or expertise in troubleshooting compatibility issues or has insights into Firefox-specific optimizations, I would greatly appreciate your input.

Thank you in advance for your time and assistance.

Got a problem on two separate computers: Mozilla Crash Reporter keeps popping up when Firefox is not even running. I'm guessing that my antivirus avast is interfering with the update service. I'm I right or wrong? Otherwise, does anyone know how to interpret this? This is the report:

This report also contains technical information about the state of the application when it crashed.

I didn't know if this needed to be in Privacy and Security Settings or Cookies, so please feel free to move this to wherever it fits best. Here is my problem. I have saved logins on a lot of sites that all work perfectly. There are several websites that I have multiple accounts that all have their login credentials saved. My problem is that there is one specific website that until recently was operating just fine, but in the last week has started a nuisance issue. When I log into the website I select the login profile I need and everything starts off just fine. About 5 minutes later, whatever I am working on gets hijacked by a dropdown appearing in the upper corner of the screen that lists the six logins that I have for that website. If I continue to try typing, nothing happens (as in, the dropdown list stays there and whatever form I was typing on no longer has any data being entered). If I press ESC, the dropdown list goes away but it also closes down the form I was using. If I use the mouse and click anywhere on the screen, then the dropdown list goes away and I can continue using the form I have open. About 5 minutes later, or if I open up a new form, the dropdown list comes back and I have to do this all over again. I have talked to IT of the website and they stated that they have never seen this issue before. Other users that also use Firefox have never mentioned this to them before. Is there a setting that I need to change? Do I need to clear the cookies for this website? Do I need to just delete all of the saved login information and then re-save it? Thank you for your help.

I am experiencing an extraordinarily strange issue. I have reinstalled windows on to new SSD drive to troubleshoot and I have verified the problem is apparently Starfield+Firefox=problems. Specifically, when I run starfield it corrupts something in windows and prevents my Web Browsers from working forever afterward until I run system restore. I have done this 3 times now. As soon as I run Starfield, Mozilla Firefox starts crashing tabs and crashing on opening quickly and repeatedly. I have used system restore to restore my system on the new HD and it fixes Firefox. But when I run Starfield again, Mozilla becomes corrupted. I was using Mozilla Firefox because my Edge and Chrome won't run without status_access_violations every 5 to 10 minutes. But Mozilla Firefox ran flawlessly since June 2022 until I opened starfield. Aside from this, my PC is reliable, fast and stable. Starfield itself runs flawlessly and smooth in Ultra-Detail. I have a Core-I7 7700K, an RTX 2080 Super and 16gb of Gskill 3200 DDR4 ram on a Gigabyte GA-X170-SLI-CF motherboard. I DO NOT overclock any components as I prefer system reliability. Also I have had starfield since the early access release last Thursday August 31st and have been fighting my computer ever since with fresh windows installs on blank hard drives trying to fix this. I have run out of options. I am writing this to you on my Office Laptop as it doesn't have browser issues. Please route this report to the appropriate support personnel, thank you!

Edit, I also tried 3 different pairs of 8GB G-Skill DDR4 ram sticks. I have also tried the other channel. I am pretty sure its not the ram. If anything something with the motherboard, or possibly I need a bios update after some random windows update. I have seen that before too. But I am more looking for what variable could the 2 programs be sharing that opening one perma-bugs the other until a system restore is run.

Edit 2, Reply from Bethesda was that they seem to have closed the request with the comment "Thank you for your feedback.". As I said they didn't have any options to report a bug they create in a 3rd part program.

I can't find any way to add to the list of document types and applications. I know I must have done (because they are different from my wife's options), but now she needs to add one, and there is no immediately obvious way to do this. How do I add a new entry in the list in Settings/General/Files and Applications/Applications?

Thanks,

Tony

What am I supposed to do about this new problem?

"XUL Runner This profile was last used with a newer version of this application. Please create a new profile." I did create a new profile. I have like 4 different profiles now from every time I've had to reinstall Firefox because it keeps crashing and freezing.

Firefox V102.0.1 up to date. Right click to open link in new tab - new tab is displayed, link is shown in new address bar, nothing is displayed in the window. Thoughts?

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

After restarting my computer last week, I suddenly couldn't reach ANY websites on my computer. I tried changing security settings. I tried deleting Firefox and reinstalling it. Still, to no avail.

I don't have any problem reaching websites via Firefox on my laptop or my mobile devices. I also have no issues with using Google Chrome or Bing.

For some reason, though, I'm suddenly having the same connectivity issue using Zoom, citing Firewall and Proxy issues (I'm a single, home user). I tried turning my security program off, and that didn't help. I also did a scan using the security software and it could find no malware.

I have tried restarting the computer, and powering off and restarting the router. No help.

I'm not sure why I'm suddenly getting this issue with my desktop. I have Dell ProSupport, and while they're trying, they haven't been able to nail anything down.

Any ideas why this would suddenly happen, and only to Firefox? (and, for some reason, the Zoom connectivity?)
