Mouse Gestures 1.5.2 (the latest official known release) is not installing with Firefox 3.0 Beta 2 (firefox 3b2).
There is an easy way to fix this issue :
-
- go to addon
(https://addons.mozilla.org/fr/firefox/addon/39)
- on the Installer button, right-click and "Save Link As ..." to save the .xpi file on your desktop
- change the file extension to .zip
- open the zip file and edit the install.rdf file
- change the Firefox <targetApplication> em:maxVersion from 2.0.0.* to 3.0.*
- save the zip and change the extension back to .xpi
- drop the .xpi file into firefox
- the installation should proceed :-)
