Firefox Community Forum

I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?

When File Explorer of Windows 11 25H2 tries to access and open an icon-file in the FF (144-64bit) profile's 'shortcutcache' folder, explorer gets Access Denied. The account running Firefox has admin rights.

Looking to the ACL of the profile folder containing the folder 'shortcutcache' show no reason for the blocking. Trying this with a new profile did not help.

Developer edition seems to be blocking Today's Deals when browsing amazon.com. Regular firefox does not do this. Suggestion on what to do to fix it.

Also trying to browse distrowatch give the following: Warning: Potential Security Risk Ahead.

I've been having an issue with picture-in-picture (PiP) mode where the subtitles and rewind/fast-forward buttons (rr/ff) won't follow the video into the small player for Disney+ specifically. I have no issues with YouTube or any other site. The subtitles and rr/ff just stay with the original video player on the site while the video is in PiP mode. I can see the subtitle button on the PiP player, but it is grayed out and I can't click it. I've updated both Firefox and my computer (Windows 11) and reinstalled Firefox, cleared cookies and cache, and still no dice. Any advice? Thanks!

(In the screenshot, the PiP player isn't showing video, but I think that's just because of Disney's anti-piracy software - I can see the video in the PiP player on my screen.)

I'm on Firefox mobile, and I keep having this issue, and trust me, I've searched for solutions, but they just haven't worked out. Wverytime I open the Firefox app, it asks me to "get started". I've had Firefox for nearly a year now and it's my default browser. The only thing I can think that could be causing this issue would be me recently syncing my account onto my computer, but that was a little while ago and it used to not do this every time. Now it is. Please help?

I get the server not found error on almost anything.

Hmm. We’re having trouble finding that site. We can’t connect to the server at [literally almost any site] If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

The site usually loads after I wait like 2-3 mins before reloading the site, or I force reload it around 7 times, but I cannot find a way to make the issue go away. I have refreshed Firefox, I have uninstalled and reinstalled it fresh, I have opened Firefox in Troubleshooting mode and the issue persists. I am at the end of my wits. Someone please give me something else to try.

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?

I have disabled uBlock Origin, Enhanced Tracking, tried Private Mode, Troubleshooting Mode to no avail.

I have also cleared cookies & data. This appears specific to v131. Any suggestions??

Firefox told me to update Firefox. I had to get help from Apple support to do so. Now the new version takes forever to load anything. I can't read comments from other people on my Facebook posts. Amazon takes forever to show the products that I am looking for. I saved both versions of Firefox when I updated, so how do I find the previous version to use? It was much better on my computer.

I just installed Mozilla VPN but when it's active my internet connection stops working. Pretty sure whatever protocol it's using is the problem with the WIFI signal, but I can't find how to change the protocol like every other VPN service allows. How do I change the VPN protocol? There is strangely no article already on this site for this common problem.

The browser just shuts down when one tries to create a new flow ... obviously there is not a way to screenshot this ... one suspects this is a javascript issue.

Details:

• OS - Debian 12 (Wayland | Gnome 43.9)
• Nightly Version - Debian Repo (mozilla-deb - 1.0) | 132.0a1 (2024-09-23) (64-bit)
• URL / Actions - make.powerautomate.com > New Instant Cloud Flow > Name it & Select Manually trigger a flow

What Else Have I Tried?

• Ungoogle Chromium - Absolutely fine, no add-ons
• Firefox mozilla-deb - 1.0 130.0.1 (64-bit) - Absolutely fine, no add-ons
