I am a tech dinosaur!Thank you in advance for any help.Lesley

I was trying to customize the toolbar and I can't recall how, but I lost access to my extension shortcuts through the menu list button on the toolbar. I've been since trying to get the button back or replace it, to access my extensions that way but I'm not finding any options to get the button back which I find ridiculous because the button is very helpful on the toolbar in utilizing your extensions. I'm kind of a newbie so I'm looking for help in how to get the button back on my toolbar so I can utilize my extensions that way, please. Thanks.

When I close tabs, and the computer stops working and I check the Task manager it turns out that firefox still runs 20-30tabs in the background when most of then have been closed and have just 4 running!!!

This occupies 100% of disk and CPU, and thw laptop stops functioning and freezes!!!!!!

And this happens all the time! How do we make firefox actualy close the tabs properly?? Without having to dig through task managerto close them again one by one?

I downloaded session manager on Firefox hoping to be able to import session file from session buddy from chrome. I tried importing the json file but it says it fails to read. Followed by some googling I found that the problem lies with the fact that session buddy files don't have several tags in current tabs in the json file so importing fails. Like mentioned here https://github.com/sienori/Tab-Session-Manager/issues/408#:~:text=Close%20Chrome%20and%20Open%20Firefox,%2C%20and%20click%20%22Open%22. I am a noob and I don't see how that could be fixed, any help, plz?

I am trying to create a new Firefox account with it's own email to be separate from this Firefox account I am posting from. However, every time I try to follow the "sign up" buttons I get redirected to the login page where I enter what I want as the new account info and receive a "Primary email account required for sign in" The email I'm trying to use for my new account is NOT registered with Firefox and I am using a freshly installed version of the browser on a new PC so no extensions are interfering.
