yahoo finance (and maybe other sites?)
I noticed with yahoo finance, and possibly another site or two I do not recall, that firefox becomes unable to open any other URLS and seems to lock up after visiting one or more of my saved favorate/bookmarked Yahoo Finance Urls.
I found a solution that works here...

The solution is not permanent and has to be applied everytime I open firefox and visit a site that causes this problem. It does NOT seem to affect M.S. Edge at all.
Is firefox / mozilla working on a permanent fix for whatever causes this issue?

Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#search104
Show us what you get when trying the site. The site loads for me. see screenshot
