Hi. I am new this is first post. Have very basic computer skills.
I use Thunderbird email client, never had problems in more than two years.
About a week ago I downloaded an "add on" a calendar to be precise. I began using it about three days ago, seemed to work fine. Then yesterday I made an entry into the calendar and Thunderbird immediately went into "Thunderbird not responding" status.
I shut the program down several times but each time as soon as I tried to click on anything in Thunderbird the same thing happened. Even shutting down my computer did not solve the problem.
I am considering a "System Restore" but I do not know the date I downloaded the Thunderbird add on. How can I find the date I added that add on is there some log or something that records actions of this type?
All/any help is appreciated
