Diễn đàn hỗ trợ Firefox

I'm running the latest FF under Win7. Seems that whenever I go to the Merriam-Webster (dot) com site, after a few seconds, my disk activity light goes solid, and the FF CPU usage spike to 10-25%. One time, to regain control of my system (because everything seemed hung) I actually had to resort to the physical power-down switch. Obviously I immediately ran a virus scan upon coming back up (scan showed all okay). Now, if I stay away from Merriam-Webster, FF behaves normally. But it's a damned dictionary site. I occasionally will need to use it or stumble into it. I've used MW in the past without problems. Does anyone know what's going on?

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

Facebook requires me to have to update Firefox even though I have the latest version! Could it be because my computer only has Windows 7? Can't find no free upgrade to 10 anymore ... buy without money will not go! I really need help!
