Firefox 19 Windows 8 64 Bit Slow

已張貼

Firefox works okay but I notice it slow down an lag. When I go on Pandora an play music it'll work fine but once I start opening other tabs it will start lagging the music. This doesn't happen on Internet Explorer. If I play a video YouTube in HD I sometimes have to let it load all the way up or it'll start lagging. I have none of these issues on Internet Explorer. What can I do to fix this?

I would firstly suggest to scan Your PC for malware. They might inject code into browser, so maybe that's the reason
