Fantastic!!! Thanks to the developer!!!

not currently downloading anything. Not even showing downloading button anywhere.
Maybe it need an update

Why does the addon name not match the name on this page? And why does the serial have to be two digits? Also, it shouldn't put a serial on single-image tweets.

Works great. It has simple yet very useful functions.

The download button this add-on provides is really harmonize to vanila design and working speed is fast. Multiple videos download is available. NO redirecting to add-site .
Downloaded files are rename to Username + status ID (+01,02,...) . It is reasonable way to make finding videos easier on Exproler.
It is to be regretted that this page is not official as Mr.exercitus sais.

Single button under the tweet (same bar as the like, retweet and other buttons), automatically downloads the video file.
Perfect.
