Rated 5 out of 5 stars

FxIF is the ONLY decent online EXIF viewer I've found. I don't know why it isn't rated the highest. The others are just cumbersome and inadequate.

As a suggestion, I wish the EXIF data could be displayed either directly in the contextual menu, in the sidebar, or in a single always-on-top window. Currently, for every image you want to inspect, you must open another "properties" window. It's the appropriate place for the info, but it has limitations -- as soon as you click the page, the properties window is hidden. Then again, perhaps Firefox could provide the option of floating, copying, and saving the "properties" window.

I'm currently using Firefox 3.5.3 for Mac and FxIF 0.3.

This review is for a previous version of the add-on (0.3). 

Your suggestions

Thank you for your kind words - and your suggestion also.
For displaying the infos in the first level of the context menu I don't think this is appropriate since it would mess up the menu for most people.

But since in future Firefox there is no standard properties menu anymore I've to add my own entry anyway and I could make displaying the infos in a submenu an option.

For displaying the infos in always the same window. Would you expect FxIF to switch infos when switching tabs/windows automatically or via context menu? The former one would be difficult/impossible to do when the image is not loaded directly (...jpg URL) but is embedded in a website.

Regarding your last sentence, could you please elaborate the more?
