Firefox Support Forum

all of a sudden , I need to update fire fox,have reinstalled it. It won't run the download, will not connect to sites I have used in the past.They want a newer version of fire fox,I have windows xp.

I'm trying to sync from Windows XP to Windows 8.1. When I sign in on XP I get a completely blank page and a few buttons. When I click on 'Reconnect to sync' I get the message "Blocked by Content Security Policy. This page has a content security policy that prevents it from being loaded in this way. Firefox prevented this page from loading in this way because the page has a content security policy that disallows it". What other way is acceptable?

For many years I use Firefox 52.9.0esr on my WinXP computer. And for even more years I have been struggling unsuccessfully with the following problem.

Under "C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Profiles\2b9qepw7.default-1469870616368\cache2" there is a folder named "entries", that is constantly inflating! It is now 49.5 GB huge! I can not delete it. Deleting process does start, but doesn’t continue even for a bit or finishes ever. I’ve tried to delete the cache via Firefox preferences unsuccessfully. Even manually via Windows Explorer, even in safe mode (F8 when the computer starts), even with TotalCommander. The folder’s size just suddenly changes to zero when I click on it, but not the real space it’s occupying on my hard drive. I even uninstalled my antivirus and tried all the methods again – to no success…

I have added a video of what happens on my drive if I click on this folder in low resolution: https://drive.google.com/file/d/1E_gqf4s31m7Gr7taW5iUOUzkwe8Oi7iT/view?usp=drivesdk In high resolution: https://drive.google.com/file/d/1EaLROHC2p510CvP24nO83wplEkaAgrA9/view?usp=drivesdk

Please help me to solve this problem!

Thank you very much in advance!

I have many computers, all with the same operating system, all with the DEFAULT Firefox install. Only on one computer do I get the "firefox content security policy" error and only when trying to log in via the "sync" tab in Firefox Options to synchronize that computer with the others.

I am a retired computer technical consultant. I'm no pedestrian user. I've been researching this problem for about a year. I've gotten nowhere. My research has come up with no answer for this problem, though there are answers for firefox content security policy that address other problems.

I am a hardware and applications software guru. I have no experience with javascript, and I suspect this IS a jafascript issue.

Can you help me?

Thank you, Graham Fisher

I am using the latest version of Firefox (112.02 32-bit) with Windows 10 but am being blocked from certain websites by the Cloudflare security app because it says that my browser is out-of-date. This was particularly embarassing when I was trying to buy tickets for a concert recently and was unable to access the venue's online payment system.

It may be that Cloudflare is confused because I occasionly use an older version of Firefox (52.9.0 32-bit) with an earlier version of Windows. How can this issue be resolved so that Cloudflare does not block legimate access to websites when I am using the most up-to-date version of Firefox?

Hello. I cannot watch videos from invidious.snopyta.org on my laptop with Firefox 52.9.0, because a message that says "No compatible source was found for this media." appears in place of the video player. However, the videos from that website do load correctly on my other PC with the latest Firefox version, and they load correctly on this laptop as well when using Google Chrome. The video found on this site, which I think is a webm, plays correctly.

What video format does invidious.snopyta serve and why can't it be played by Firefox?

I got a "Secure connection failed during a connection to duckduckgo.com. I am using WIN xp and Mypal browser. I get the same message if I try Firefox. What do I do now?

W10 Pro (sys info & TS info are below) I run both w/32-bit 91.4.1 esr & 64-bit 95.0.2 on the same machine. I tried to manually upgrade the esr to 64-bit but am told 'unable - system incompatible' and get the W XP & Vista support ended at 52.9...I'm running 32-bit 91.4 AND 64-bit . Help me understand if/what is incompatible so I can manually push my esr to 64-bit. Getting to 64-bit from 32 (per help page) says to just download and run the 64-bit ESR setup.exe. That fails...same issue...incompatible. FF setup thinks my OS isn't W10 Pro....so does the ESR FF 'application menu'...and the TS info. My ESR is set as the default browser app. AND I don't have any (known) issue with the 64-bit 95.0.2 Advice? Do I need to uninstall the 32-bit esr strangely I am already running 91.4.1 32-bit esr...says HELP/about.??? I'd like to know what esr is actually running...I presume 32-bit. Thx, wgk
