Whenever my Laptop slows down, it seems to always be Firefox’s fault. Why, I’m not sure. Possibly from overusing Firefox, or a bug in Firefox. Maybe because of something to do with the Java Applet. It could even be because I use Vista. But if you are a Firefox user and all of a sudden your computer seems to screech to a halt after taking it out of hibernate or something similar, heres what you should do. (Take note that this can happen both when you are and aren’t using Firefox but were using it recently. First, press the key’s Alt, Ctrl, and Del. This will open up a menu that has Task Manager manager on the bottom if you use Windows Vista. That is what you should click. And in Windows XP and earlier, the Task Manager will open up automatically.
In case you don’t know what Windows Operating System you have, click on the below screenshots to see bigger screenshots of Vista and XP below. The first is Windows XP, and the second is Windows Vista.
Now that the Task Manager is open, simply look through the list of open applications in the Processes tab, which I’ve labeled with a “1” in the below picture. If you see two firefox’s, you should simply click on each of the Firefox’s and then click on the End Process button (labeled with a red “2”) to quickly end it. You may get a message that will ask you to confirm the action, click yes/continue if the message appears. You will now notice a notable speed increase with your computer. Later on though when re-opening Firefox you may see a “Restore Session” option, but I would recommend to click on “Start New Session” so your computer doesn’t possibly begin to slow down again.
Thats it, but I would recommend only using this method though when needed as it may cause glitches Firefox afterwards. Like always, if you need any help I will gladly help with this and anything else within my knowledge, just leave a comment asking for it. And if I can’t help, I’ll gladly point you in the right direction where you can recieve free help.

Well I did some more research, and found that that the bug type that causes this is called a “Memory Leak”. Unfortunately, there are actually dozens upon dozens of reasons this can happen, and there are many of them still unfixed. The best thing to do would be to simply exit out of Firefox every now and then and restart your computer to get rid of any leaks, or just do what I mentioned in the article above if you don’t want to restart your computer. Luckily though, bugs in Firefox are being fixed by people who have the know-how. You can see some recent news on these bugs here. Also, heres a list of some of the Memory Leak Bugs.
