Very low value on the Mac. Shortcut key is set to F7 which is useless. First of all F* type shortcuts on the Mac are somewhere between painful and really painful depending on the Mac model. Second F7 seems to already bound to "caret browsing" in Firefox for the Mac.

What about the "context menu" you say? Using this add-on's context menu is about the same pain level as other solutions to getting rid of formatting. So using the context menu does not justify installing this add-on.

Finally, you can set your own shortcut key, but all the obvious ones are already locked up by Firefox or its Developer Tools and can't be disabled as far as I can tell.

Even if you are willing to suffer the pain of using this add-on, it frequently barfs up error messages and fails to work.

So the net-net is that this extension really has no value for Mac users. Why is such a useless add-on being recommended by Mozilla? Based on the recommendation I installed it and wasted a few hours trying to get it to do anything useful before uninstalling it. Not the experience one would expect from a Mozilla recommended add-on.
