Tabs are increasingly often not loading
Whenever opening a new tab, Firefox only shows a blank window. Reloading doesn't help (more accurately, reloading doesn't happen when you try to activate it). This happens everywhere, also on this very website.
Frequency is increasing. It started a few days ago with one tab in 5-10 showing a blank, to 3 or 4 attempts required to open any page.
I've uninstalled Chrome last month because it would always run a single processor core at max capacity, even when Chrome wasn't opened. If you don't fix this, I might end up with with Edge or something. Which stinks, but less than Firefox at this point.

Could the problem be caused by an extension? https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems
If you can't find an answer any other way, you could test Troubleshoot Mode. https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

I had the problem recently with a few pages only. A Greasemonkey script was the problem.

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
