Diễn đàn hỗ trợ 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

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.

A few days ago I was told via message that firefox will stop support for windows 10. I ungraded my system to windows 11 and downloaded the appropriate version of firefox. Now I'm getting the same message again. Please help. I like firefox but being told continuously that it's no longer supported even though I've upgraded my system to one that is supported is a pain.

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.

Subject: Reset font size without using menus

By accidentally pressing and/or holding one or more keys on my PC, I seem to have shrunk the font size which I need to reset.

When I try to use OPTIONS GENERAL the screen will not scroll down to the FONT setting

Could you please tell me how to reset font size without using the menus?

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?
