One of the things the Sony PlayStation 3 is known for is its ability to install new applications. However, the applications that can be installed are very limited and do not include Mozilla Firefox. But you can install Firefox by using the "Install Other OS" feature that Sony has included since late 2006. If you install Linux, you can go ahead and install Firefox on your PS3.
Plug the USB storage device into your computer. Create a folder named "PS3" in the root of the drive. Within this, make a "otheros" folder.
Move "otheros.self" into the "otheros" folder.
Extract the contents of the add-on ISO CD. Navigate to the "kbroot" folder and locate the "otheros.bld" file. Move this into your "otheros" folder on the USB drive.
Remove the USB device and insert it into the PS3. It should recognize that you have inserted a new storage device and request that you format. Do so.
On the PS3, navigate to "Install Other OS," located under "System Settings" in the "Settings" menu. Click "Accept" to begin the process.
Navigate to "Other OS," located under "System Settings" in the "Settings" menu once you are brought back to the menu.
Plug in your keyboard and mouse. These are required for navigation.
Insert the Fedora Core 5 CD into the PS3. Restart the console.
Wait for the prompt. When prompted, type in: install-fc sda.
Agree when it asks whether or not you are ready to begin installation.
Switch the disc out for the Addon Installer disc you burned earlier. When this process completes, type "reboot" in order to begin Linux or "halt" to shut off the console power.
Type in "yum --enablerepo=development update firefox" to install Firefox.

If you want to switch back to your gaming operating system, simply type in boot-game-os. If you find yourself unable to switch back, you can restore your PS3 to factory settings by holding down the power button for five seconds when booting up.
