Firefox Support Forum

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.

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?

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?

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?

I want to log in Tanki online games but not working...asking me to search Advanced panel. I dont know what is that...have HP 620 with Windows XP inside...thanks anyway...(:-())

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.

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'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?

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

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.

Hi,

I was very disappointed earlier on today when I saw the many add-ons you can choose from, for the 1st time, and tried to install one I really liked on my desktop (which runs on XP PRO).

The add-on is called "I Don't Mind Cookies". It wouldn't install as I needed to update the version of Firefox I currently used and provided me with a link to facilitate this.

I followed all instructions throughout and surprisingly quickly I found it completed, and had message confirming the successful update of OS to ver.59 2.

Returned to add-on above and tried to install it again. I must say I felt even more disappointed when the same error message appeared. Clearly, the add-on was not so sure I'd done as directed; either that or it perhaps it got confused and then passed it on to me...

Can anyone help me, please, as I've had an awful outing this week trying to get our Sky Account sorted - my repeated attempts to get 2 things sorted culminated with my last call taking well over 2hrs, involving 5 different departments and a total of 7 agents - thankfully, I only had to tell 4 of them the whole sorry tale in full and although this sad episode was finally resolved (well, sort of), I'm not confident I'll ever be quite the same again.
