This is a really useful add-on, because basically you want to have an option to quickly look at the details of any picture. Sometimes the add-on is in your way, because it shows the zoomed image too fast, so you have to find a good balance concerning the setting for the delay time. Sometimes, when you move a tab to a new instance, zooming a picture there will set the focus to the old firefox instance, but there´s a workaround: simply minimize all windows but the current instance, and you´re done. Great add-on, thank you so much for boosting productivity!

Sorry, I forgot this additional hint for the focus-bug: it happens often (always?), when you first move a tab to a new instance. If you never move tabs to new Firefox-windows, I think the error doesn´t occur.

At first thank you very much for this very practical add-on! Greatly well done!

At second I want to report a bug here (cause this goes faster for me than registering somewhere else): Sometimes it happens, if you are using Firefox with multiple instances, that after hovering the focus to the referring Firefox gets lost, and the zoomed image is displayed in front of a different instance. This happens often, but not always.

At third I want to make a suggestion for improvement: could you add an option for not zooming, if the image is larger than xxx pixels in height? Because there´s always zooming, even if the image is big enough (screen filling). That would be very great! Thanks in advance!
