Firefox Support Forum

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 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 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 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

I am using Firefox version 112.02 with Windows 10 and am being told by some websites that my browser is out-of-date and that I cannot continue. Then today I was purchasing tickets for a show and the checkout was blocked by another message which said "Firefox Can’t Open This Page. To protect your security, **********.co.uk will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

Please advise how these measures can be removed or disabled as they are a perfect nuisance.
