The best and the most useful add-on for Firefox. First on the list of must have add-ons.

I don't get it.... how did I ever manage to properly view images without this plugin? How did I survive browsing the internet without this? This plugin seems to be just a small convenience but it just becomes a necessity once you are used to having it.
So a bit like a drug but healthier (also for your eyes. No more squinting)

Stopped working on Instagram and Facebook quite a while ago. Last update was 2 years ago so we definitely need another update to fix this.

One thing I would add. An (optional?) on/off icon for the toolbar!

Awesome add-on, i fully use it on daily basis, it helps me a lot in my research work. I learned to tweak its settings to meet my needs, but one single drawback it have in my opinion, it doesn't have (or I still haven't figure it out yet) the possibility to save offline the custom setting I made, for future use in case i need to re-install the browser.

VERY inconsistent results, but most of the time just creates a popup image thats the same size as the one hovering above, so pointless.

Used to work perfectly, have been using it for years, but since today it doesn't seem to work anymore with Instagram (while hovering over any image, the waiting cursor spins endlessly). Would it be possible to fix it? Thanks in advance!

It is simple but it is a game changer.
