A Firefox add-on to get rid of Flash video players.
Because there are two things I hate the most on the "web":
Let's tackle Flash.
If you have the Flash plugin enabled, then this addon is of no use for you.
What it does
Will replace known Flash embed on third party website with the HTML5 equivalent.
Vimeo: you need H264 support for that since Vimeo has always hated royalty free codec like WebM and preferred to tell Firefox users to install Safari, even on Linux.
The original Mozilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=769117
See doc/main.md for more details.
Install the Add-on SDK https://developer.mozilla.org/en-US/Add-ons/SDK/Tutorials/Installation
Then drop the no-flash.xpi file into you browser.
This is currently experimental. But I use it every day.
