Attached is a picture I took of what I'm experiencing. At first I thought it was an issue with my monitor or perhaps my computer hardware, but it seems to only affect Firefox. Besides the obvious black squares you can see, I invite you to look at the top of the page displayed. Where it talks about Megan thee stallion, the "a" and "n" of "Megan" are kind of cut off by something. I also experienced twice, maybe three times the whole page going blank for a second or so before returning to normal (not my whole screen, just the firefox browser). I just checked and Firefox is up to date. I don't know if this is relevant, but I also checked Windows Defender and saw it had detected a threat, named Win32/OfferCore. I have since deleted it and have started a complete analysis of my computer which is still underway. My OS is Windows 10. I hope this can be resolved, as currently it is stopping me from being able to read an article on Wikipedia, with many of the letters being kind of cut in the same fashion as with "Megan". Thanks for any help, it'll be appreciated
