[Brief] (https://addons.mozilla.org/firefox/addon/brief/) is a feed reading extension for Mozilla Firefox, developed by Adam Kowalczyk, and released under the [MPL 1.1] (http://www.mozilla.org/MPL/1.1/ "Mozilla Public License, version 1.1").
Because of the UI changes brought by its major release 1.6 (a regression in usability, for some people), this independent fork does the old Brief 1.5.4 compatible with more recent Firefox releases. Some minor enhancements landed too.
It's all shared under the [MPL 2.0] (http://www.mozilla.org/MPL/2.0/ "Mozilla Public License, version 2.0").
Note that because the [changes brought by Firefox 22] (https://bugzilla.mozilla.org/show_bug.cgi?id=834457), the compatibility was broken in a hard way and the development was dropped.
Check the [wiki's Downloads] (https://github.com/KerSp66zQAx/brief/wiki/Downloads) page.
Last development snapshot is incompatible with Firefox 22 and later ([More info] (#4)).
[Digest] (https://addons.mozilla.org/firefox/addon/digest/), a recent fork of Brief 1.7a1 "aiming to update it for the modern Firefox versions, fix the bugs still present and develop it furtherer".
