Firefox causes 100% CPU usage when opening couple tabs at the same time!!!

I Am on desktop:

i5 9600KF (high performance mode) 16GB 3200mhz ram NVME... Windows 10 Pro x64 Firefox last stable

When I open Firefox tabs aren't loaded all at the same time, but they are suspended. So after that: when I switch between 6 tabs quickly - they start to open at the same time. And CPU usage skyrockets to 100% LOL! Given I Am on high end PC - this is joke! I was using chrome and had hundreds of tabs and Chrome doesn't even suspend them by default. They open all at the same time I think!

So there is something wrong! I tried troubleshooting mode and it was the same problem!

Thanks for help!

Hi!

I want to change the default serif and monospace fonts (Atkinson Hyperlegible and Hack, respectively) in Firefox. However, the fonts that are listed in the advanced font settings appear to be a specific list that doesn't update with the system-installed fonts, so I cannot pick the previously mentioned fonts. I tried working around by tweaking with the about:config values, but so far no luck. Any advice?

Thanks in advance, Lucas

v 91.0.1 on Mac Tried 2 ways. No effect. - Settings >> Privacy and Security >> Cookies and Site Data >> Manage Data, or Clear Data--both leave cookies after Removing or Clearing All. Looks like 16 MB of cookies remain--from 2-3 weeks old. Tried repeatedly-- the list is cleared (while selecting remove All), then immediately comes back in entirety once I check again.

- Menu >> History >> Clear Recent History >> Clear All, "Everything" >> No effect.

- I deleted a Firefox profile that was not in use. No effect.

THX for guidance. best to All.
