Help! Lost Firefox somehow and had to re-install. Lost all history and presets. What can I do?

more options

Not sure what happened. I thought I clicked on an update and suddenly Firefox refused to open. I had to re-install Firefox and not sure how to get my preset tabs and history back. I could really use your help as I'm not the most computer literate person and also thanks in advance. Right now everything is in pink, not my fav, to differentiate from what I had before. I deleted my original firefox icon on my taskbar as It would not open or give me internet access.

Hi LindaBechter, See if this helps -

No help. Only one profile listed for 7/3/22.

If Firefox starts up without your bookmarks, passwords, saved tabs and other settings, check whether your data is available in a different profile. This can happen because Firefox creates a dedicated profile for each Firefox installation.

To recover your Firefox data and settings from another profile:

Type about:profiles into the Firefox address bar and press the Enter key. This will open the About Profiles page. This page should list at least one profile and could list many. The profile that Firefox is currently using will have this: This is the profile in use and it cannot be deleted.

Please do not delete any profiles. Don't use any Remove buttons. If you have another profile listed on this page, it may contain your missing profile data. You can click the Launch profile in new browser button to open another Firefox window using that profile. If the other profile doesn't contain your missing data, simply close that new window. If it does contain the missing data, you can set it as the profile that Firefox will open by default. Click the Set as default profile button for that profile and Firefox will use it automatically the next time you open Firefox.
