Fixing slow and not responding Firefox

After the latest updates of Firefox it has started run extremely slow both at startup and when surfing. I often got "not responding" and freeze of Firefox for several seconds when loading a web page. I have also seen this on other computers. Finally I have found the magic cure. What you need to do is a reset that will rebuild your profile while keeping the most important settings (bookmarks, passwords, etc) and removing old junk.

To do the reset open the "Troubleshooting Information" window:
Windows XP: Help -> Troubleshooting Information
For later versions of Windows: Firefox > Help -> Troubleshooting Information 

Then press the Reset Firefox button.

For a detailed description see the Mozilla support here.
