Problem: Regardless of whether there are none or many instances of FF
open, nothing happens in response to left-clicking on an email link (or
right-clicking and selecting Open Link In Browser). In reviewing Google
searches about this problem, this has been an ongoing problem for years,
for many revisions of TB and FF.
I went through the usual recommendations about checking that TB is the
default mail client and various others things, including adjusting the
some network.protocol.... settings using the Config Editor. Since my
problem just started today, weeks after downloading the latest versions
of FF and TB, I thought maybe CCleaner screwed up a registry entry,
which perhaps it did.
Anyway, I found the fix to be simple. In TB:
1. Go to Tool/Options/Attachments/Incoming.
2. In the Content Type column there should be two entries: http and https.
3. Even though the Action column already says Use Firefox, highlight http
3a. Click on the triangle
3b. Select Use other...
3c. Browse to the location of firefox.exe, select it, and click on Open.
In my computer it's in C:\Program Files\Mozilla Firefox\.
4. Highlight https and repeat steps 3a, 3b, and 3c.
I closed TB and FF and restarted them, but that may not be necessary.
That's it. I hope this helps.
(I'm using FF 13.0.1 and TB 13.0.1 with Windows XP.)
