What is a .FBU file?
The .FBU file extension stands for a FEBE Firefox Backup File. This type of file is created by a program called FEBE, which is short for "Firefox Environment Backup Extension." FEBE is an add-on for the Firefox web browser that allows users to save a backup of their Firefox data. This data includes a variety of important information such as the extensions (add-ons that add new features to the browser), themes (which change the appearance of the browser), bookmarks (saved web addresses for quick access), preferences (custom settings), and user cookies (small pieces of data stored by websites to remember information about the user).
When you use FEBE to create a backup, it collects all these pieces of information and saves them into a single .FBU file. This is very useful because it means you can easily restore your Firefox setup if you need to reinstall the browser or if you want to set up Firefox the same way on a different computer. One of the neat features of FEBE is that it can save all the extensions as a single .XPI file within the .FBU backup. This .XPI file can then be used to quickly install all your extensions at once on another Firefox installation, making it a great tool for syncing your Firefox environment across multiple devices.
To open a .FBU file, you will need to use the FEBE program. Since FEBE is a Firefox extension, you must have Firefox installed on your computer to use it. Once you have FEBE installed, you can open the .FBU file through the FEBE interface in Firefox. This will allow you to restore your backed-up data and settings to your Firefox browser.
