Damn good.

Adjusting settings, I'm using it not automatically, but with CTRL keyboard pressed (for on of numerous example of adjustments)

works well and fast.

Chrome refugee here, thanks

I spent many hours switching from Chrome to Firefox only because of this extension

Byebye Chrome.
Hello Firefox and finally i have my Imagus back.
Because having a jpeg zoom when you hover your mouse over it is a "dangerous addon".

I can't use the internet without it anymore

The only extension enlarges even Youtube profile images.

Search for updated versions of the sieves on "Imagus Reddit" (type into a search engine). There you should also ask your questions about problems with Imagus / Imagus Mod.

huge time saver, scrollable carousal is the highlight

Literally an essential once you start using it. It's one of the most usefull extensions for any browser.
