You may have a java script problem.  Go to Add/Remove programs and remove your Java Runtime Environment and then go to http://www.java.com/en/download/ie_auto.jsp to complete the automatic update.  This should probably take care of your problem but you could have other issues (security settings of your browser, activex settings, popup blocker, etc.)

Spyware is known to cause many lockups and slow downs. Start with downloading spybot search & destroy, lavasoft adaware, and grisoft AVG. Scan your computer with these programs, and if they ask if they can run next startup, let them. Once that is done, if you are still having problems then look at the startup manager included with spybot and uncheck all the autoupdating programs and uneeded agents such as winamp or real player.

You might have a lot of programs running and have little RAM memory left. Or maybe you might have a virus. I recomend that you check for viruses and for your memory.

Is it a old computer?  How much RAM are you running?  Could be that you have spyware and malicious programs running in the background that you are not aware of.

Try Allowing Cookies, Clearing temp files and cookies. Or cchek your Anti Virus/Spyware and firewall settings.

Check all cable connections, mouse, monitor, AC power cord etc. sometimes they work loose. If everything appears OK, you may need to reload windows. Some viruses will do this by corrupting your program files. You can try a emergency disk, restart in SAFE mode, or just format the drive and reload Windows and all the drivers. I do this about every 3 months to clean out junk and corrupt files. You will find your PC runs much faster.

Try a disk clean-up, cookies, temp internet files, etc, maybe that will help. I haven't used Firefox for a while and I don't remember if there is a cookie blocker that you may have inadvertantly put on those pages. Check your internet congfigurations and options for Firefox.

Your processor may be going down as well, if it is overheating (or just wore out) it might be cycling at odd intervals or slower than intended which could cause the time discrepancy and the mouse freezing.
