How to install SS SiteBoost 0.29b with Firefox 4

SS SiteBoost is a nice add-on for Firefox, enhancing the Shutterstock's user interface for contributors.

Unfortunately, the version 0.29b is disabled as incompatible in Firefox 4. It actually works fine, you just need to change the max supported version of Firefox from 4.0b8pre to 4.0:

1. Go to the author's web site: http://351.pl/ss_siteboost_FF.html. Right click on "SS SiteBoost 0.29" and save it on your computer.
2. sssiteboost.xpi is nothing more than a zip archive. Open it and extract install.rdf file (you may need to temporarly change .xpi extension to .zip).
3. In install.rdf, find 4.0b8pre and change it to 4.0.*
4. Pack the modified install.rdf back into sssiteboost.xpi.
5. Drug and drop sssiteboost.xpi into the Firefox window to install.
