I-Firefox Isithangami Sokwesekwa

Is there a way to transfer all my log ins and their words from my desktop Mac to my new lap top Mac Air. I need to do it possible my a flash drive since the first time I did it by migration and overloaded the lap top with all the stuff on the desk top. After lots of work to delete everything and reinstall the OS I did it by the flash drive. But I don't have all my logins and their passwords on the lap top.

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

This morning I received an email stating: If you are running a version of Firefox equal to or older than Firefox 78 (general release or ESR) and you have a Mozilla account, you must follow these steps to ensure continued operation of your account in Firefox: I have firefox 115.7.0esr (64-bit) running on a mid 2010 macBookPro with High Sierra OS 10.13.6

My question: what does this mean? Is my FF equal or older? And is a Mozilla account the same as a FF account? PLEASE help me, by explaining exactly what I'm supposed to do and HOW and reply in simple comprehensible language, I am NOT a tech/nerd/geek and already following all these numbers has given me a headache! Thanks in advance.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!
