Firefox 技術支援討論區

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?

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

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?

closed private window w/ 'history' display open. Now the Private window always displays the 'history' sidebar every time it's opened. ps: old system i can't afford to replace running vista with latest FF v. available for it. Works great for what i want to do. Thanks.

I am configuring a new desktop. My university uses Duo for 2-step security. When I use Firefox 106.0.5, Duo returns "500: Internal Server Error". Edge works. I'm assuming this is a new problem since I haven't located any other mentions of it so I'm assuming that this is either a new problem or particular to the University of Alabama.

I have e-bay on firefox Vista and (Microsoft and when I click on item watching and go into the item to move it to my watch list it will not work....... it this problem and I do believe due to the support on the computer. With said this is the only thin not working, it did it before and I remove fire fox and re-installed and it did work but this time I did the same and did not work.

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!
