Import from Edge after forced migration - Firefox corruped user data after update

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

Did you use Sync to recover this data as Sync has limits when it comes to transfer history ?

You can copy certain files with Firefox closed from one profile folder to another profile folder to transfer personal data. Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.
