Browser back-doors !?

Mozilla's chief of research Brendan Eich

 

is requesting that the source code of Firefox should be audited.

He's pointing out that if governments are trying to coerce companies like Lava-bit to hand over data, they might be tapping browsers as well.

So is he hinting at : that Firefox has been forced to introduce a back-door ?
