I keep getting the same dialogue box upon opening Firefox but don't know what to do about it "Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard drive is not full or close to full. It is recommended that you exit the browser and fix the problem. If you continue to use this browser session, you might see incorrect browser behaviour when accessing security features." I have gone to tools - general tab - browse files - but it wont let me browse or set a place to staore files. Any ideas?
