If you could specify the year, month, day, hour, minute, and second in the save file name, it would have been convenient because you could arrange images created from multiple videos in the order in which they were viewed.

The tab freezes really badly, hotkeys do not work correctly and you have to exit full screen to be able to take a screenshot because it does not have a button-icon like other extensions next to the controls for easy use.

Worked great for months, but unfortunately no longer works. Clicking the add-on doesn't enable it anymore. At this moment, it's my only way to take video screenshots on websites that aren't YouTube. Hoping for a fix someday.
