All Mangas Reader

Lately (and i mean the last few months) the all mangas reader app has been running very slowly to the point to when i click the extension icon (sharingan) it takes from 20 to 50 seconds to load my mangas list, and i have only the non read appear on the list which is no more than10 mangas. If i click on the go to next chapter icon (the 2 forward arrowheads) while this loading is not complete it will send my to a new home tab on chrome. I wanted to know if this is normal i have around 150 mangas on my list so i tough this might cause the problem or if this is has something to do with the newer version of the extension or a mistake on the configuration on my part. Thank you for your time.

are you updated to the latest version?
how many websites do you have turned on?

I have around 5 sites manga fox, manga reader, eat manga, unix manga, batoto and manga chapter and i am running the latest version.

could you post all your AMR settings? You're running the new AMR 1.4.0 released today? What version of chrome are you running?
Have you tried exporting your manga, uninstalling AMR, deleting any bsync/extension data you have, reinstalling AMR and importing your list?

actually the problem seems to have become lesser with the new version and yes i have also the latest chrome,
and i did that just a couple months ago when the mangafox.me issue came to light but not since (the re-install and delete).
