Select your video player by left clicking on the Better-Tumblr-Video icon in the top right corner of Chrome. Caveats: Doesn't work on all pages. Some pages of tumblr, like the search page and certain user pages (depends on theme), are completely ensconced in an iframe, which prevents the extension from seeing any videos on the page.

This is a sorely needed feature on Tumblr, and it's ridiculous that I need a separate Chrome extension so I don't damage my ears trying to watch videos on Tumblr. (Thank you for creating this, by the way!) My only complaint is that it only worked for one day before the volume bar completely disappeared again. I've tried turning it on and off and restarting my browser, but it's not coming back. Back to the drawing board.
Currently, the extension does not offer an option to download videos, but! The addition of an actual volume button is already so great! Hopefully you can update it (although, I won't blame you for not doing that, the sites has gone through some troubles) Even if I can only use 50% of this extension, it's amazing for what it can still do! I recommend this just to get a better player for Tumblr videos
the only reason i wanted this is to download the video, doesnt do that
