This version 10.5 fix looks like a step backward: Fix: Full/Text Zoom Level and Minimum Font Size were applied to stand-alone image pages.
I liked being able to right click and view an image on it's own separate tab, but now with this "fix" I can no longer zoom the stand-alone image in and out. I'm going back to version 10.4 as this "fix" took away what I mostly use this extension for.

Edit: Thanks for the fix for this in 10.7!
