Φόρουμ υποστήριξης - Firefox

I recently got a new computer. Installed firefox onto it. Brought over my profile with all my data and bookmarks. But for the life of me, the page would just sporadically flicker. I tried messing with the settings; performance settings; hardware acceleration. I tried refreshing firefox. But nothing.

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

I am on a MacBook Pro with Sonoma 14.4, and the lastest version of Firefox. The YouTube website will not load. It looks like the attached screen shot. I can access the site with other browsers. I can play a YouTube video with Firefox if I have a link, but I cannot see the rest of the page - just the video itself.

I have two audio device plugged in. firefox only outputs to the usb devise even though i have selected the aux out on windows. all other programs use the selected audio out but not firefox

any help would be appreciated
