my browser was running insanely slow so i decided to close it out only to open it back up to being logged out, tabs gone (but still synced for now) and at least 1 extension which is now no longer available for download gone! i'm p***ed mostly because the extension (enhancer for youtube) was the only good one of it's kind and now it's gone for absolutely no reason. i did not clear any data or cookies prior to this so why?!
