A multi-protocol messenger offered one program for several accounts. The original article introduced Instantbird through that idea, comparing it with Pidgin and noting the convenience of reducing the number of separate applications a user needed.
A Mozilla interface and a connection library
The source described Instantbird as combining Mozilla technology for displaying messages with libpurple, the library associated with Pidgin, for connections to messaging networks.
That divided the visible interface from much of the work of talking to different protocols. The software was presented as free and open source, allowing participation under its applicable licences.
The networks named by the source
The article listed AIM, Gadu-Gadu, Google Talk, ICQ, IRC, MSN, QQ, XMPP and Yahoo among its examples. Those names illustrate the messaging landscape in which the article was written.
They are not a current compatibility promise. A client may remain downloadable while an external service changes or closes the protocol it once supported.
Several operating systems
The author welcomed the ability to use the application on Windows, Mac OS X and Linux. A client intended to simplify communication would be less useful if it excluded many of the computers people actually used.
The article did not provide a current support table. Old system requirements should be read in their historical context rather than applied to a modern operating system.
Extensions
Instantbird's extension model was compared with Firefox add-ons. The author saw user contributions as a way to expand the application and improve the experience around the basic messaging functions.
That model also made the state and compatibility of each particular extension relevant. An old feature description alone says little about whether an extension is suitable to run today.
The original comparison with Pidgin
The source considered Instantbird promising but described Pidgin as more complete at the time, particularly because of its plugin collection. That judgement was a snapshot of the two products during the article's period.
The Pidgin archive article provides the companion account. Both illustrate the wider aim of giving users one manageable view of several communication services.
