Blocks ALL images from ALL messages. Not a single one showed a red eye icon.

It's a great extension, but I removed 2 stars because for the last week or so it started making all images disappear. I wish when I clicked on the red eye icon, that it would let me see what was blocked and have an option to display an item of my choice.

Doesn't work. No red eye, just broken images, most of which are NOT pixel tracking.

This broke Drive (corrupted Google Sheets). Not worth the hassle until they fix it.
