Claws Mail 3.0.0-rc2 external browser


I am new to this windows version of claws mail.

Almost everything is working, my only problem at the moment is getting the browser to work.

When I (doulbe)±click on an url in an email firefox isn’t starting, it isn’t working with right click and open with browser too. I have choosen the “firefox” entry from the pre configured setting (drop down list) in the configuration - external programs setting.
What do I have to do to get this working ?

Oh, and is it possible to use a dictionary (German & English) while composing a message?

Kind regards,


If you use “firefox” in the settings, make sure that “firefox” is found on the PATH. If not, set the full path to firefox in the prefs instead, for example:
“c:\program files\firefox\firefox.exe” “%s”

Spell check (aspell) support has not yet been ported to Windows, sorry. It wouldn’t be the hardest part to port, though, as aspell runs on Windows.

“C:\Programme\Mozilla Firefox\firefox” ‘%s’
is working, thank you.

It is a bit suprising that
firefox ‘%s’
isn’t working as opening a dos prompt and typing firefox not in its directory still starts it.
