Cinnamon bugs in LMDE

[mister_playb]

1. Battery is always at 94%, in windows and ubuntu is at 100%, and the laptop is just one month old.
2. The os/cinnamon is in my native language, but firefox, thunderbird, libreoffice are all in english, pidgin not, for some reason.
3. Connectig for the first time to wifi, I have to type my password not once but twice (the password was not wrong i just have to type it twice) and then the network key.
