Is the Thunderbird-Firefox relationship getting you down? Does clicking links occasionally result in Thunderbird totally locking up for over a minute, before Firefox bursts into life with the requested page?
Apparently this started around Thunderbird v3, and here's how to fix it all the way up to v12:
- Tools > Options
- "Advanced" tab
- "Config Editor…"
- "I'll be careful, I promise!"
- Set preference network.protocol-handler.warn-external.http to true.
- Click on some link in an existing email
- You now get the choice of which browser to use. Do not select Firefox. Instead, choose "Other" and locate
firefox.exeon your hard drive.
- "OK" everything.
Apparently Thunderbird works best when you pretend to it that its sibling Firefox is a third-party application that needs a simple shell invocation.
