Good product, slow release schedule Rated 4 out of 5 stars

This is good product doing what it is supposed to do. In Firefox 5 it has couple bugs with the Headings showing in wrong places, but I mainly use it to send the pages to the Validator. One bad thing about this product is that every time Firefox has new update, this add on gets disabled and then it's weeks before new version is created that works with new version of Firefox. Now that Firefox has very rapid release schedule of major versions, I can't update it right away and need to wait for this add-on's new version. I suggest the team reworks their code so that this tool migrates to new versions of Firefox right away or at least start working on new version when the beta of new Firefox version is released. Firefox 6 was released last week, but this add on is still not updated to work with it. Firefox 7 is coming in a month and the beta is already available, so I see no reason why the new version can't be made available a day or two after it releases.

This review is for a previous version of the add-on (1.5.7.0.1-signed.1-signed).
