Hover Zoom+ has worked well for most sites I've visited (and thankfully still does), but I've recently encountered an issue where it doesn't zoom on anything while browsing Twitch. I can mouse over a stream, and it'll act like it's trying to do something, but then it just infinite-loops without actually zooming in on anything, and I don't know if it's something Twitch did recently or what.

Works well. Some issues I noticed is that it does not play gif files on Pixiv and you are only given the option to view the file frame by frame. I haven't noticed any issues on other websites when it comes to playing animated videos/gifs. If you are looking at Facebook Photos, your browser will start to lag super badly the more you scroll down. This is fixed by disabling the add-on. Decent add-on.

good ext love it

its good for the most part. some websites don't work and i have to disable and re enable when i start firefox which is kinda weird

Works very well but very inconsistent, especially when saving images. One day it can saves images and gifs just fine the next day it' unresponsive.

after f.update in google maps after hovering on names city/country doesn't open little window with images and even on names/links of places hovered on map after showing that little window with images doesn't zoom/open-full the image (hovered). If I click on image and menu left opens the images hovered are zoomed (little slower).
