Firefox 社区论坛

Lately I have been having an issue on Firefox with YouTube stopping and buffering after one minute. This occurs on all videos but only on Firefox. YouTube runs fine on other browsers.

I have tried changing the resolution and disabling ad blockers, but without resolving the situation. I am using the most recent build of Firefox. I have also expanded the size of the cache (after clearing it), but that did not help.

I can't seem to find any real help with this online, and I would appreciate any assistance anyone can give me.

Thanks!!

Hi Ive just installed macOS Sequoia and Firefox is really slow and showing a refreshing spining icon with a few tabs open, this never happened before the update. Is there anything I can do?
