Here below is a huge list of User agents. Save it as user-agents.xml . This list has 570+ UA's but if it's still small for you than you can go here and download complete list allagents.xml 700KB. I have not installed complete list because it can decrese the performance and speed of Firefox.
After downloading Click on Tools > Default User Agent > Edit User Agents...
It will open a dialog box in this click on Import and locate file which you have downloaded. Press OK.
Enjoy...!!!
