Works great, but needs updating Rated 4 out of 5 stars
I'm using this add-on with Firefox 7. Although I need to use the Add-On Compatibility Reporter to let it install, it mostly works. The only problem I have is that if I right-click on a category, the pop-up menu ("open in tabs", "rename label", etc.) is drawn without a background, so it is hard to read. It still works, but it's ugly.
Hopefully, the author will update this really useful add-on at some point, but I'm not holding my breath, since it was last updated four years ago.
Update: Still works with FF 9.0.1.
In addition to the issue mentioned above, it is less useful when used on a Mac with a trackpad. I can center/wheel-click on a folder to open the contents in tabs, but it's not possible to do this if your mouse/trackpad doesn't support center/wheel clicking. Apple's pointing devices can be configured to support left- and right-clicks, but not center/wheel-clicks.
Finally, when adding/modifying a bookmark, the labels are not populated in the dialog, and the pull-down menu never works.
I really like this add-on, but it really needs to be completed/updated. Does the author read these comments?
