amazing extension, very helpful

I haven't even fully explored what this extension is capable of, but I absolutely love it. If anyone is confused about what it does and is sifting through reviews like I was for an explanation: The tracking essentially syncs up with your MAL account in a literal sense (when streaming from any of the listed websites). Once you finish an episode/the video player gets about a minute from the end of an episode, it will relay that info to your MAL and mark it so that it says you have watched **/12~ episodes, so you don't need to do it yourself.

This won't happen purely on it's own though, in case you don't want it to do this for any particular reason. The reason for this is, once you start an anime, a small pop up will appear above the video player on the first episode only, and once you click 'okay,' it will start the sync and track the rest of that season. Once you get to the end of a season/the last episode, another pop-up box will appear asking you to rate it, and when you do, it will mark it as 'completed' in your MAL library, also giving it the same rating which I think is fantastic. This feature alone gets 5 stars from me, even if I am diappointed with 'auto full screen.'

Regarding 'auto full screen': Many streaming websites automatically load and move to the next episode when you're watching them; like Netflix. However, you always have to make it full screen every time. I hoped 'auto full screen' meant that, when it loads the next episode, it automatically puts the video player into full screen. I have even searched through many extensions that may provide this feature, but to no avail.

I did briefly check the library that MAL-sync provides, but that didn't work, there were only three anime there marked as complete, so it doesn't seem it synced with my library properly. So, it doesn't seem this extension comes without its bugs, but hey, it's free, and this is simply a review, so I'm not complaining.

Despite these two things, I still absolutely love this extension and it is an complete must for any avid anime streamer. The tracker works fantastically (at least on Hianime, I have no way of knowing if it may work differently on different platforms).

It's perfect, it automatically tracks the episodes I watch AND Syncs it to sites like SIMKL. a must have

Thank you MAL
