I'm not able to solve this issue.

Financial chart does not load it keeps buffering. The same is true for twitch but videos on youtube work fine.

I'm thankful if you could help me with this one.

For two days I have been unable to access the internet using my default Mozilla Firefox browser. I have used Mozilla as my default browser for many years with no problems, but have had to use alternative browsers not only to access my emails on Outlook, as well as other nominal sites, but even to sign into my Mozilla account, I had to use Microsoft Edge browser. I have made no changes to my settings or internet security. Please advise. Thankyou

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

1. https://kdice.com/
2. https://latinitium.com/
3. https://theysaidso.com/
4. https://opensource.org/
5. httpe://obsidian.rocks/

Unable to find list of blocked email addresses. Went to "settings" / "Security & Privacy". No luck. I have no problem in deleting addresses. UNBLOCKING is eluding me.

When using Google Meet in Firefox browser, I am only able to share my window, not my screen. When I choose "share screen", it says I must change my permissions - but my permissions settings have not changed and this is a problem I have started having only in the last few days.

I do not know where I am supposed to change these permissions settings.

I have checked my permissions in settings > privacy & security > permissions - there is nothing there about screen sharing.

I have checked my permissions in padlock > connection > more information > permissions and the only options I have for screen sharing are "always ask" (default), which is set. The only other option I have is "block" which is not set.

My Firefox browser is up-to-date.

Can anyone help? Thanks!

Recent issue (Nov/24): when logging into some sites I've used before, the Send, Pay etc button doesn't do anything. If I do the same login on Chrome, it works. Also finding Hotmail too sluggish to use on Firefox and forced to use that on Chrome as well.
