Firefox issues

Ever since I downloaded the newest version of Firefox (3.5.2 I presume), I have encountered a ridiculous amount of issues.
1: Facebook will load at extremely slow speeds, sometimes not even load at all.
2: I can get into my Comcast email account, but I cannot load the inbox or any of the folders.
3: Up until today, I could not type anything in Gmail. I can type now, but it will not send any email.
4: A lot of times, images will not load. A specific example: 4chanarchive.org: I can browse the site, but none of the images will load.

I know this is a Firefox problem because I have no issues on Internet Explorer, or browsing the internet on my PSP. Anyone else encounter any of this?

 

Never upload the newest version of Firefox. 90% of the time they aren't beta tested and have numerous amounts of flaws.

Download a later version, such as Firefox 3.

 

agreed just get the stable version and it will auto update when the new releases are out of beta
