Hi. It is possible to create your own hacked version for FF5 which will keep you going until an official release.
Firstly, change maxVersion in the ec2ui.rdf file to 5.0+ this allows the xpi to actually install.
Secondly I noticed the context menus now have a transparent background. To fix this change the popup element to menupopup in the relevant overlay.xul files
Hope this helps!
