I had some massive issues with Mozilla Firefox and long story short, barely managed to salvage my profile with years and years of tabs, bookmarks, history and so on. Now while I was trying to fix it, I had to keep on using a newly installed Firefox with a completely new profile. This means I have another several months of history that I would like to keep as I put back my old profile. Is there a way to merge the two profiles with their tabs, history and bookmarks because that would really help me out?

If the old Profile can be run in Firefox, you can open the Library window and Export those bookmarks in HTML format. Then the resultant bookmarks.html file can be imported into a different Profile and have those bookmarks appended to the bookmarks in that other Profile. IOW, those bookmarks will be merged. https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer

No such export & import features exist for browsing history or for tabs.

But recent versions of Firefox do save a bit of "session history" (tabs history) in the Profile folder in a folder named "session-store backups". The .js files in that folder can be viewed in a Text program and the URL's copied to crudely "recover" them.

You could try using this utility program to view browsing history and probably "export" that data, but Firefox can't import whatever type of file that "export" would generate. http://www.nirsoft.net/utils/browsing_history_view.html
