When I open any websites, they begin to load and then stop, this also occurs with youtube videos. However, if I move the mouse or just click the firefox icon showing the opened windows while watching a video, there isn't a problem. Can I fix this? I've got the most recent version of Firefox and even uninstalled it.

hi winsyao, multiple other affected users have reported that this was an issue caused by malware on their pc. please run a full scan of your system with the free version of malwarebytes and adwcleaner (both these security tools are free).
