Comment 71 for bug 37828

Bruce: there are a few things to keep in mind here:

1. The pango patch is not part of Mozilla's builds. That said, most Linux distros apply the patch since upstream Firefox fails to render a number of languages they care about.

2. The version of Firefox in Gutsy uses the same rendering engine as the one in Dapper (Gecko 1.8).

3. The Mozilla guys have been working on complex text rendering (using Pango on Linux) for Gecko 1.9, but that won't reach users til Firefox 3.0.

It seems that no one with the knowledge to fix the existing Pango patch to handle ligatures has the time to do so.
