Rated 5 out of 5 stars

Yes, 1.72 has stopped working -unfortunately the author or someone has seen fit to censor and remove my comments from yesterday.

====EDIT====
Hi, no problem sorry if you thought I was complaining. I was more bothered my review praising your Addon had been removed too.

Thanks again for all the hard work with this Addon :-) We all appreciate it.

This review is for a previous version of the add-on (1.7.1.1-signed). 

This problem is now fixed in 1.7.3, which is now the default version. Upgrade to this latest version and it should work again.

Version 1.7.2 was not working for users who had removed Thumbnail Zoom Plus' toolbutton from the tool bar. Because of this problem I withdrew release1.7.2 so no more users run into this problem.

The Mozilla add-on site automatically deleted all reviews associated with 1.7.2 when I removed that version. I didn't intentionally remove the reviews; it's just a side-effect. To the contrary, I had actually added a note about the problem to the description on the add-on's page, so I wasn't hiding the problem.

Sorry for the inconvenience.

David
