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.

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.

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/

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.)

When browsing on Google Images, any time I swipe from one picture to the next, it is like the image doesn't want to swipe and is actively fighting against me. It is glitchy, bouncing around before I can drag it across my screen.

This is an issue of mobile FireFox, not of my device. Swiping and scrolling on other web browsers, such as Samsung Internet or Google Chrome, is seamless and buttery smooth.

Bookmarks folder still takes too long to open when adding and editing bookmarks. When is this going to get fixed? Or where can i download an old version of Firefox for Android that does not have this issue?

After the version 149, a very strange issue happens to me with Firefox. When I try to log in to some services (Google account, WhatsApp, Mozilla account) the browser freezes. That does not happen if I turn the hardware acceleration off so I essentially thought there is some issue with my graphics drivers which I then updated (Nvidia 580.142 drivers for Geforce GTX 960). But what is very strange is that the issue isn't present when I use Firefox in private mode! That means: Normal mode, HW acceleration on -- freezing Normal mode, HW acceleration off -- not freezing Private mode, HW acceleration on -- not freezing I switched to the ESR version now which works fine too. Still, I am curious about what is going on and I would like to find a solution. My system is fully updated Arch Linux. I cannot share my data since I can't log in to my Mozilla account. Thanks in advance!
