This is a fork of PDF.js designed for SeaMonkey 2.49+ and Pale Moon 29+.
Note that any "testing" that exists for this fork is very limited, and some features may not work. Before filing a bug on this fork, first check to see if the problem occurs on the newest version of Firefox - if it does, file the bug on Mozilla's upstream repository instead.
