Diễn đàn hỗ trợ 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?

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!
