Firefox Community Forum

Previously, had no problem loading YouTube videos in multiple tabs, switching between them and them playing their videos with no freezing , pausing or buffering. Since the last upgrade loading a single YouTube video causes it to freeze and continually buffer. And Firefox is spawning multile copies of itself in task manager. (One instance had 15 copies.)

Firefox149开始，网页看抖音，每滑到下一条就卡顿2，3秒，换回148及之前的版本就没这问题 Starting from Firefox 149, when watching Tiktok videos on the web, there is a lag of 2-3 seconds every time I swipe to the next item. Switching back to versions 148 and earlier does not have this issue， https://www.douyin.com/

Whenever I launch a YouTube video, It starts then the whole page freezes. No links work and no menus shows up when I click my mouse. I can do nothing to get the video to unfreeze. All I ca do is close the window.

everytime I try to get to my sites its very slow and it says mozilla firefox not responding If I wait for a while it will finally allow me to get to my site but it takes a long time

For some weeks now, the "File" menu randomly opens by itself then closes a second or two later. It seems to happen once I get focus on a page. For example, if I open a new tab then go to Google and ask a question, once the answer is returned, within a second or two the File menu drops down then closes again. I have the latest version of FF (149.0), 64-bit under Windows 10. There are a couple of settings in about:config that were suggested to be changed by ChatGPT but this hasn't made any difference.
