Firefox Support Forum

Hi there,

I just got some message saying that my Firefox version needed to be updated and by hastily taping on the ok button I did it without noticing that it had done it to a newer version no longer supported by my Mac OS.

I wanted to go back to the most recent version still supported by El Capitan 10.11.6, so I installed again the 78.10.0ESR and now all my browsing history from many years back is gone.

Could you please help me getting my history back?

Going through internet through several hours didn't bring any good solution to my problem.

Thanks on advance.

I refreshed Firefox, now my logins are all gone and when I input them to sites, click on Save, nothing will save. Also my Facebook page is not missing half the stuff on the page.
