RC-1 - Cannot launch Firefox from Thunderbird

Using openSUSE RC-1. I’m having problems launching Firefox from Thunderbird. Whether it be an html link or browsing for extensions.

I can launch Firefox from KMail.

Anyone else?


I’ve seen this before with Ubuntu. Open Thunderbird and go to edit ->prefs -> advanced -> general -> advanced configuration. Search for




Make sure both point to


In openSUSE 11.2 RC 1 -the problem with the fix is that Thunderbird 3.0b4 “about:config” no longer uses




I’m getting the following error message in the Error Console when selecting

Tools → Add-ons → Browse All Add-ons or See All Recommended Add-ons

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIExternalProtocolService.loadUrl]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://global/content/contentAreaUtils.js :: openURL :: line 924"  data: no]

I didn’t have this problem in Milestone 8.

I’m sure this must be happening to other users??

I just looked, and it is Thunderbird 3 beta in the RC1 repos. The arguments I posted aren’t even there anymore. I would delete the thunderbird folder in /home, reinstall and see if it works. If not, you need to file a bug report. I just installed it from the RC1 DVD, and it works fine here.

I have installed KDE 4.3.1 using the 64-bit DVD RC 1. Have you installed the 32-bit or 64-bit?
No matter how many times I have deleted the .thunderbird folder, removed Thunderbird 3.04b, I cannot get Firefox started from an html link or browse for add-ons from Thunderbird.

However, I found a workaround using “about:config” in Thunderbird 3.04b.

Change from false to true the following:

network.protocal-handler.warn-external.http   user set   boolean   true
network.protocal-handler.warn-external.https   user set   boolean   true

A window pops up asking which application the user wants to launch. I selected firefox.

It now works!
