EVERY time I re-install Linux I run into this problem again: the ThunderBird email client does not open links that I click in the browser. Then I spend hours on the Internet trying to find a fix that actually works.
This time, the fix that worked is from http://askubuntu.com/a/312932:
In Thunderbird 11.0.1, it is simple, yet not intuitive:
- Go to Preferences (Menu Edit → Preferences).
- Click on the Attachments tab.
- In the Content Type and Action section set HTTPS, HTTP, and FTP to Use google-chrome (or other desired browser).
That worked for me after trying numerous things in terminal that did not work.
