Doesn't work on google images.

Crap! Not even close to Thumbnail Zoom Plus. Why does Firefox recommend this?? Almost never works. PLEASE some kind soul make a better extension!

It certainly isn't working on Google Images anymore for me. But perfectly on Bing. I hate Google,anyway.

Not work on pixiv.net.

Si quiere más estrellas tendría que explicar el por qué de los permisos que pide.

It automatically sends enlarged pictures to couple big search engines Settings->Advanced->Send image to

Add custom license, no source code available and you have privacy disaster

Not happy with Imagus' hijacking of my Windows cursor to give me same lame whirligig. I wish Thumbnail Zoom Plus would get their new FF plugin done so I could get rid of this malware.

Doesn't work the majority of the time. I am really annoyed that this doesn't work at all the majority of the time and it just keeps getting worse. Only around 20% of the time it works. I always keep either getting an orange spinner (e.g. Facebook profile pictures from the Newsfeed) or nothing happens. The extension is really flawed.

Check permissions -- "Access your data for all websites".
According to support.mozilla.org, this includes user names and passwords!

Now it wants more permissions to access my downloads. I'm sick of this shit. There's got to be an alternative to giving up all of my privacy just to look at a large thumbnail.

Isn't worth a thing, compared to Thumbnail Zoom Plus.
As Thumbnail doesn't work on the new version of Firefox, I disintalled the latter and came back to the old one I had before.
The only way to have Thumbnail work.
Too many add-ons don't work on the new Firefox version so I threw Imagus directly in the trash, with the new Firefox version.

Der Vorgänger Tumbnail Zoom Plus war deutlich besser !

Hover over an image and get a spinning wheel that does... NOTHING! Utterly pointless add-on.

Hold the cursor over the image and wait and wait and wait.... deleted.

It works very well but it´s not privacy friendly at all. That custom licence tickles me so I had to uninstall it. Looking for an open source alternative

you ask for browser history without explaining why. it is not acceptable. uninstalled

Please make the need for addtional rights (download files and browse history??) OPTIONAL. Deactivated until then.

I replaced it by "Image Max URL" and now I'm happy!

Removed after it asked for browser history.

Why on earth would this extension need to read my browsing history?
Thanks, but no thanks.
