Diễn đàn hỗ trợ Firefox

I'm uninstalled, Firefox and reinstalled it and cleared the cache. And it's still either not linking to certain sites at all or not, opening them correctly or completely. I don't wanna spend any more time than necessary on this. If you can help me, that would be great.And if not, I'll just go back to chrome

Recently my system updated Firefox to version 149.0.2. It works great! However, it will not display my homepage which is yahoo.com. I can go to any other website and everything is normal. But when I click on the little house for "Homepage" it briefly displays and then goes blank.

This does not happen when I use a different browser.

Please advise.

I have cleared my cache but I still cannot access the open pages from the task bar. Some are trying to load but don't. They also don't shut down at once when I press the x command. Some pages are working OK.
