Seems to work ok in 5.0.1 Rated 5 out of 5 stars

I updated the rdf file (Google "edit an xpi file") to max version 9.9 and it appears to work just fine in Firefox 5.0.1 on my new Windows 7 64-bit machine. This is great news since I love this add-on, especially that it duplicates the history of the tab as well.

Simple Edit for FF 3.6 Rated 5 out of 5 stars

This is probably one on my most used add-ons. I do not think there is a day I do not use it. I was disappointed when it did not work for version 3.6 But then I followed the instructions carefully at http://kb.mozillazine.org/Editing_an_add-on_to_change_its_compatibility and it worked like a charm!!

This is probably one on my most used add-ons. I do not think there is a day I don't use it. I was disappointed when it didn't work for version 3.5.0. But then I followed the instructions carefully at http://kb.mozillazine.org/Editing_an_add-on_to_change_its_compatibility and it worked like a charm!!
