I’ve been using Mozilla Thunderbird for some time now, and recently it started bugging me all the time when checking my emails. A window pops up each time asking me for security certificates exception, and even though I keep selecting the “Permanently store this exception” option, Thunderbird still keeps asking me every single time I open it.
So just today, after a couple of months of annoyance I finally got tired of it and looked up a solution. It’s actually very easy to fix, but being lazy as I am I never bothered to fix it until now.
Basically, what you need to do is this:
- Open Thunderbird and click the “Tools” in the menu bar
- Switch to “Advanced” tab
- Select the “Certificates” tab
- Click the “Validation” button
- Disable the certificate validation
For convenience you can also view the steps in the screenshot below:
In a majority of cases, you don’t need to confirm certificates and whatnot every single time you want to read your email, and it doesn’t really pose a security issue. This should make your work with this excellent email client more enjoyable.
