Doesn't work anymore since the update, so I'm changing my rating.

It’s really sad to see that the author doesn’t care about their own creation. For two months, it hasn’t been working as it should, and there’s no update to fix it. Now this add-on is useless.

newest update removes BetterViewer from being the Default viewer and simply adds it as an option at the bottom of the menu.

...this entirely defeats the point of BetterViewer, as I installed it specifically to REPLACE the default image viewer, not to have an option.

Also I created an account just to write this review, BetterViewer was almost perfect before, now it's pretty much useless.

Ever since version 2 it doesn't open images in BetterViewer by default. And that's highly annoying as it was the only reason why I used it so extensively compared to other similar extensions. If I now forget to go all the way down in context menu after right click and instead of "open image in new tab" I don't click "Open image in betterviewer" I have to do additional steps of clicking again and choosing it.

Don't know if this is Mozilla's reason or not, but it makes me want to use this extension less and remove it, as it's then easier to just screenshot images via other apps in my PC and/or open them in that editor and it'll be same amount of clicks.

Look how they butchered my boy. Why no longer replacing the default image viewer??

This extension is unironically better than any built-in photo editor/viewer Windows ever had by default. 99% of the things I want to do with the picture, I can do while it's still in the browser.
Crazy good.

Perfect image viewer! I really like the zoom its very convenient. The rotate feature for those wrongly portrait photos in landscape, the editing everything is excellent. 100% recommended addon

Great extension, thank you!

Love this addon! The only drawback is, it doesn't work on Reddit

Amazing addon. If there is a way to, please allow this for installation in android. It is working pretty well, but needs a specific third-party firefox fork to install.

5/5 for being the only 'image viewer' extension out of the dozen I've tried with the ability to pan/move the entire image within the space of the browser, instead of it being locked in the center.

Does exaclty what it says and that in a very smooth way.

Two things that keep me from switching from the now-unsupported Better Image Viewer: the dark theme isn't the same as firefox's default, and the image can't be made to fit the entire window (not fullscreen, just browser window width or length). Even better if the latter can be set to default.

Great extension.. But photo editor is not working right now.. A simple request to the developer: Is it possible to add a settings button to switch "always show details panel" . That would be very helpful..
