You install Firefox on your freshly minted computer. Everything is great for a while. Firefox loads up in seconds, web pages open in a snap, and everything works. But then, over time, Firefox starts acting up. It gets slower and slower. Things that used to work stops working. Sudden freeze-ups and crashes begin appearing. I am sure this is something many of you have personally experienced. As our Firefox profile begins accumulating clutter, the performance and stability of Firefox takes a hit. This might be due to a toolbar you unknowingly installed, or some extension that has a memory leak bug. The thing is that finding out the root cause is both time consuming and frustrating.
In order to make things simpler, Mozilla is adding a magical reset button to Firefox. The new option will be available under about:support (accessible via Help –> Troubleshooting Information). Clicking on this button will create a new profile with default settings, which will hopefully solve your performance issues. Firefox will also copy over your browsing history, cookies, saved form history, saved passwords, and bookmarks. This means that you will essentially have a fresh install of Firefox, but with all of your personal data intact.
The biggest drawback of the reset feature is its location. It’s buried deep within Firefox, and is practically impossible to discover. To counter this problem, Mozilla is currently thinking about prompting the user to reset Firefox after it crashes for the third time. It is also exploring the possibility of giving Windows users this option when they are reinstalling Firefox.
