[TUT] Installing "incompatible add ons" with firefox

[Loveable]

Lets say you're running 3.1 beta Firefox and the add on compatibility is only for 3.0.0, it wont let you install because it's "incompatible".

Things you will need:
7-Zip(Winrar will work also)
Firefox User Agent Switcher(or an alternative browser)


Steps:
1. Switch user agents(Tools>User Agent Switcher) or open an alternative browser
2. Go to the addon firefox page and right-click save as on the download button
3. Open the archive with 7-Zip or Winrar
4. Open the install.rdf file
5. Edit where it says <em:maxVersion>3.0.*</em:maxVersion> and change the version inside to your version of firefox(To get your firefox version go to Help>About Mozilla Firefox) and save it
6. Open the XPI file with firefox and you're done
