Thanks everyone, those who posted and those who PMed me, for all of your help. It took literally everyone's advice (and sympathy) to get me through this. It was a combination of registry errors, incorrect Firefox installation and extension update errors.
I don't know why everyone keeps saying Firefox is easy to use. I've never had this kind of problem with IE. After three years of Firefox, and every month something going wrong with it, I'm going back to IE.
Again, thanks~! You guys are so awesome. I'm so sorry if this topic was discussed before but I couldn't even do a search on here to find it because of how insane Firefox was acting.
This is crazy. I tried googling this crap to figure out what's going on. I tried to enter some pages that had info and I can't enter them. I immediately get firefox's error message:
Mozilla Crash Reporter
Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.
To help us diagnose this problem, you can send us a crash report.
...I sincerely hope the 25 or so consecutive crash reports they got will do some good. >_< I cannot enter gmail. I cannot enter yahoo mail. I can't download or enter the noscript.net or get ad block plus. I can't even download Internet Explorer to see if this is only affecting Firefox! WTF?!!! I can't do anything. Sometimes while writing this out on wordpad this forum will also crash on me even though I haven't clicked on anything. I hope this post goes through.
I also cannot cut and paste. It takes me several tries. Please help?
