Heads up: Translate Firefox and Thunderbird keywords

[Gabor Kelemen]

Hi translators

Recently the Firefox and Thunderbird desktop files got keywords support, 
which means: if a user types one of the keywords into the Unity dash, 
the relevant application shows up.
So it would be important to translate these strings into as many 
languages as possible.

Unfortunately, these applications are not supported on Launchpad 
Translations, so we have to edit the following wiki pages:

https://wiki.ubuntu.com/Translations/Wanted/FirefoxDesktop - fill in the 
translation of "Internet;WWW;Browser;Web;Explorer" under the Keywords column
https://wiki.ubuntu.com/Translations/Wanted/ThunderbirdDesktop - fill in 
the translation of "Email;E-mail;Newsgroup;Feed;RSS" under the Keywords 
column.

As with other keywords, these do not have to be word by word 
translations. Instead you can list the words that users are likely to 
search for when they want to browse the web / write a mail.

Thanks for your collaboration
