Works grate and it's very helpfully!

shit´s dope yo

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
