TRANSLATION ONLY ------------------------------- How do I set German as the preferred language? Whenever I update the Firefox browser via download he sets me english as language. I would like to have the version in German, because otherwise I get about google only in English. ------------------------------------------------------------------------------------------------------- Hi, this gives a good over view but is mixed and will need to take Firefox info and install language packs and set as default : https://addons.mozilla.org/en-US/firefox/addon/deutsch-de-language-pack/ and dictionary https://addons.mozilla.org/en-US/firefox/addon/german-dictionary/ and set up as per below. https://www.w3.org/International/questions/qa-lang-priorities The best way is to uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : *https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles *https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer Reinstall with Current Release Firefox 59.0.2 with a Full Version Installer *https://www.mozilla.org/firefox/all/ Find German on above Page and Install.

You can check the order of the installed languages. *Options/Preferences -> General -> Languages If the Firefox user interface (toolbars) is in the wrong language or if you want to change the current language then download Firefox in the language of your choice. *https://www.mozilla.org/en-US/firefox/all/
