I cant print out any email. Neither can I find the options submenu when I click the 3 bar icon in the top left

You have to be in your opened email site or app to get the print option to correctly print the email message.

Sorry you misunderstand. I cannot turn off the pop up blocker on Firefox despite Googling how to fix this. I cannot get to the options submenu so cannot access the security sub-sub menu, either. Here is the error message:

"Grrr! A popup blocker may be preventing the application from opening the page. If you have a popup blocker, try disabling it to open the window."

What popup blocker?

Grrr! A popup blocker may be preventing the application from opening the page. If you have a popup blocker, try disabling it to open the window.

The one in Mozilla Firefox. Never had this problem with Google Chrome browser

You need to really look at your Firefox extension manager to see what is going on since that isn't a Firefox browser caused.

How do I do that???? I am not geeky like everyone else is. Sorry

You can always do a internet search and you will get links to find those questions. That's what I do. This is what I found search for such as Firefox extensions manager.

It is in Settings on Firefox whether on Windows, macOS or Linux as it has not been Options/Preferences for a long time now. https://support.mozilla.org/en-US/kb/pop-blocker-settings-exceptions-troubleshooting
