Note: When firefox updates, it shows the add-on as not compatible. It is actually compatible, but there seems to be some crossed wires somewhere and I’m looking in to it. In the mean time just re-install the add-on from here and it will work again (verified on Firefox 7.0.1 and 8 beta) This should be fixed now, if you download elasticfox from here again, firefox should not disable the plugin after updates.

I was unable to find a version of elasticfox that was compatible with newer versions of firefox, so I pulled the code and made a simple update to the install files and the chrome (in ff>5 the menus in elasticfox went transparent and made it annoying to use.) The result is basically the same plugin with extended compatibility. I punched the max version to 20.0 to avoid having to rebuild each version, but can’t guarantee it will work for any version above 7beta.  Anyway, click the link below to download the xpi.
