فَيَرفُكس لأندرويد Support Forum

I've noticed that Firefox has been running very slowly on my computer recently. Pages take a long time to load, and the browser often freezes or becomes unresponsive. I've already tried clearing the cache and disabling extensions, but the problem persists. I'm using the latest version of Firefox on Windows 10. Are there any other troubleshooting steps I can take to improve performance for my website?

I tried to use youtube thumbnails like adding a layer on thumbnails, and changing the youtube logo... Suddenly it doesn't work, tried combinations from DOM to everything. As currently expected, you can see the PC version on https://github.com/Omarplayz233/pearify-firefox
