I love having this app available for checking details in image files; however, Firefox 10 update warns that it is no longer compatible and will be disabled, so are there any plans to upgrade it? Thanks.

This review is for a previous version of the add-on (1.70). 

Firefox 10

I've read that Firefox 10+ will assume that an extension is compatible unless explicitly told otherwise, but that the updater is unaware of this and gives a false warning. So, it seems that you should ignore the warning and upgrade anyway; please let me know if there are any problems.
