EDIT: works fine with the fix suggested by the dev, thanks!

It's been great in the past 2 months that I've been using it, but recently the video has been freezing randomly like the other recent reviews say. Audio continues to play however. Simply pausing/unpausing as well as refreshing the tab will only give me a black video. I have to close and reopen the tab to fix it, but it will freeze again eventually. This doesn't happen in the native player. This is a great extension, please look into this issue!
