Thunderbird Export URLs
There's an easy way to get Thunderbird sort of working with Firefox right out of the box with Arch.
Don't forget to type the following as root to install the 2 programs via pacman
pacman -Sy mozilla-firefox pacman -Sy mozilla-thunderbird
Then go to your hidden thunderbird directory in your home directory.
Or use a graphical filebrowser like Konqueror or Nautilus. Make sure to enable 'view hidden files and folders.'
You'll see a folder that looks something like this
Go into that folder and find the file named prefs.js and open it with your text editor of choice.
IMPORTANT - Make absolute sure that Thunderbird is CLOSED. Otherwise this change to the text file will have no effect.
Add to the bottom of the prefs.js file the following line and save the file.
Then restart thunderbird. URL's clicked in Thunderbird should now open in Firefox. Unfortunately they do not recieve focus. You still have to click on Firefox after clicking the URL. If anyone knows a fix to this PLEASE edit this.
You can change whether links are opened in new tabs or in new windows by opening up /usr/bin/mozilla-firefox in a text editor.
There are two lines near the top that say:
This setup will open URL's in a new window. Simply comment the first line and uncomment the second line to open URL's in a new tab!
I hope this was helpful! Please refine this as needed!
Another way to do that is to select the right radiobutton in Edit/Preferences/Advanced/Tabbed Browsing in your Firefox browser menu. Belive or not but it works on my PC :)
