When I open email, I receive a screen message saying"no emails". Then my emails populate. When I try to open emails , I get a message saying " thunderbird is not responding", then it takes sometimes a minute before it responds and lets me open an email. Same goes when I try to delete emails, I get the not responding message, and it takes sometimes 30 seconds or more before they delete. This problem just started a week ago. Never had a problem like this in the past.

How can I fix this problem? I am also showings 170 plus bugs . Do I need to do anything for that?
