If you have galleys of misery with Firefox, such as a Firefox that takes a long time to start, or even doesn’t start at all, or you wade through the grits while using it, here is an article that will help you.
Go to the Firefox menu (the burger in the upper right corner), then click “Help” and then “Troubleshooting Information”.
You can also enter the URL address bar :
Then you will find this nice page that allows you to do several interesting things.
First you can click the “Repair Firefox” button, which will return Firefox to its “default value”, i.e. a clean installation. Warning, this will remove your extensions, and your configuration + cache settings, cookies, saved passwords … etc… The big reset what!
You can also, if you know which extensions or settings are causing you problems, restart in safe mode, i.e. without activated modules, and clean up by hand.
But more often, the concern about Firefox’s slow start comes from cache that is a little too heavy or corrupt. In this case, I invite you to press the ” Empty Boot Cache ” button. This will clear the cache and restart Firefox. You won’t lose your settings or extensions, and you’ll find a good browser like the one on the first day!
Now, if you want to save your entire Firefox profile to migrate to a new computer, for example, without having to reinstall your extensions, lose your saved passwords or your favorites, you can choose :
Create an account in Firefox Sync .
Or click on the button ” Show in search engine ” in the line “Profile folder” and then save the profile folder used by Firefox. Convenient!
