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!!!

When I try to forward a link from a webpage (using Firefox) it automatically sends it from my email address through Thunderbird. I'd like to switch the setting so it uses my Apple Mail email address. Is this possible?

AdBlock Plus extension does not work after updating Firefox (to version 102.3.Oesr) on desktop MacPro. Deleting the preference file (pref.js) has made no difference.

This problem has not occurred after updating Firefox on my laptop Mac Book Pro.

Both computer use OS High Sierra (10.13.6).

Please advise. Thank you.
