Mozilla Thunderbird Tips & Tricks
Adding support for new languages to the spellchecker
Default builds of Mozilla Thunderbird from mozilla.org come with
only an US English spellchecking dictionary. One can easily add new dictionaries
by placing any dictionary in myspell format (this usually means two files: *.aff and *.dic) in
Since the format used (myspell) is the same as
OpenOffice uses, one can simply remove
<thunderbird-home>/components/myspell/ completely and instead
make a symlink with the same name pointing to
OpenOffice stores its dictionaries.
This way, all dictionaries installed for
OpenOffice are immediately made available
to the Thunderbird spellchecker.
Fixing problems with fonts
If some characters displayed by Mozilla (including Thunderbird and Firefox) seem to come from different fonts than the font used for the rest of the text, configuring FontConfig usually helps.
