Hello,
Not clear whether @Swingline0 has given up on the Store only or on this extension in general, but this is a super important part of my day-to-day usage, and I have had a strange experience of it suddenly and reliably hanging all of my Google tabs.
That is, it has worked fine for a while, but all of a sudden I got to a place where, every new tab open that shares a Google session (this is: Gmail, Google Search, Google Groups -- which I reached from Google search while trying to debug this) will last for a maximum of, say, maybe 10 seconds before they just completely hang and stop accepting input.
It happened a while ago and I wasn't diligent about removing plugins, and started getting on fine using Firefox... But then reformatted my system and tried Chrome again. All has been fine, but after about a week of having this plugin installed, the problem started to recur.
Today I removed a couple extensions one-by-one to see if the problem would solve. This was, I think, the second one that I removed, and seemed to fix it immediately.
Just posting here for anyone else experiencing this, or if there are any thoughts about what might be up. I saw that other post about LocalStorage not being instanced, and am thinking that may be related.
