Φόρουμ υποστήριξης - Firefox

I'm having problems streaming live video on srf.ch (Swiss public television). The whole tab becomes unusable after streaming for a few minutes. Playback just stops and it's impossible to reload or navigate to a different address using the same tab.

This happens with a clean profile using two different computers with very different hardware. I'm able to reproduce it using Firefox 111 and 112, but not with Firefox 110. It doesn't happen in Chrome.

Unfortunately, I couldn't report it as a web compatibility bug. The person reviewing the issue wasn't able to access the streams due to geoblocking (VPN doesn't help). They asked me to provide additional information such as console logs. But even the console stops working when the problem occurs and there are no error messages before that.

Is there anything else I could try to help diagnosing this issue or is it a lost case?

Yesterday when Firefox 111.0 64 bit was installed, updated the unified extension button shows up and it cannot be made to not appear or hidden. I even tried to about:config and change the extensions.unifiedExtensions.enabled from true to false and restarted Firefox yet the extensions button still appears. On older foxfire versions could get rid of it by doing the above and it worked but this new version 111.0 64bit I cannot get rig of the extensions button icon that appears on the end of the tool bar. Please fix it so I don`t have to see this button in the Firefox toolbar at the end of it. I even had a computer online tech try and he says you have it fixed so it cannot be removed. I see others have complained about not being able to remove the button from the tool bar also..
