Mozilla Firefox is still the web browser with the most plug-ins and extensions to choose from. Today I will show in my opinion one of the most useful ones.
If you are afraid of being hacked or someone else using your Facebook account you can enable option that will send you an email or text message in case your account has been accessed from a device that you never used before.
If you are a "private" person and don't want your profile picture or name to appear on your friend's feed next to ads you liked, then follow this steps.
Google Docs or these days Google Drive can make collaborating with your colleagues or friends much easier by sharing Google Document, Spreadsheet, Presentation, Pictures or a whole folder.
If you have activated the option to store passwords in Mozilla Firefox, than you can easily look at all password you have entered when you were browsing websites.
