Firefox - First time launch
The first time you start the "Firefox" browser, it will automatically ask if you want to import your settings, bookmarks and passwords from the previously used browser. To do this, select your previously used browser from the list and click "Next".
If you have previously worked with several profiles (in which your bookmarks, passwords, etc. are stored), you must now select one of the profiles. If you have worked with only one profile so far, this window will be skipped automatically and you will be shown the third window right away.
When selecting the default homepage, please select the second option and click "Next".
After a final confirmation, you can now work with your old browser settings using the Firefox browser.
