After up grading my computer and installing Firefox I no longer have a favorites list and can't save websites.
Hi, m42folker, There are a few ways to fix this problem, here is a link https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks to help you.
Did you previously create a backup of your personal data ?
Were you previously using Sync ? Do you have a C:/Windows.old folder that can possibly have you personal data ?
You can check for issues with the places.sqlite and favicons.sqlite databases in the Firefox profile folder.
- use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page
If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.
