Writing efficient user interfaces is the main maxim, here at Vimperator labs. We often follow the Vim way of doing things, but extend its principles when necessary. Towards this end, we’ve created the liberator library for Mozilla based applications, to encapsulate as many of these generic principles as possible, and liberate developers from the tedium of reinventing the wheel.
NOTE: Vimperator will stop functioning with Firefox 57!
Firefox 57 will change its add-on ecosystem to be exclusively based on WebExtensions . While this offers (some) compatibility with extensions written for Chrome and Microsoft Edge, it removes the possibility to do many advanced stuff which Vimperator does. Additionally, it would require a full rewrite of Vimperator, which nobody has volunteered for. Therefore we will stop supporting any Firefox version later than Firefox 56. Head over to our GitHub page for a list of alternatives or a detailed discussion .
