Links Not Opening and Can't Download Anything
I can't seem to open certain links - especially in Gmail if I click on a link it won't open. Anything that requires me to upload from my computer - it won't bring up the dialog box. I can't download PDF's from Firefox. I then have to go to chrome to do the same thing without a problem.
This issue only started happening once I updated Firefox 3 weeks ago.
