It have sketchy name but it is so far THE best addon for manga bookmarking

ok after testing I have few issues
1)I do not see option to show miniature of cover when browsing bookmarks
2)when you search manga in build-in search box, not every site that have such manga shows up
3)when you bookmark same manga on multiple pages you can not swap places nor they update all at once. so sometimes even you have read like 70chapters on site x, you see only 1 chapter on site z

Useful, viable and if anything goes wrong with the webpage you can look for the same manga in different pages in two clicks, simply perfect
it's everything i ever wanted in pc
If I had extra pocket money i would totally donate to their patron https://www.patreon.com/allmangasreader

Works beautifully! Does exactly what it claims to, and makes reading manga on compatible sites a dream! If you're a manga fan, you need this add-on!

They have done a pretty good job at helping me keep tracks of my favorite mangas.

I used this extension back in the day when it was only available in Chrome and now it's finally here! It's super convenient to read manga and has lots of options to tweak to the reader's preferences.
