I feel your pain. Now firefox is dropping extension support, entirely. All of the extensions and plug-ins that we use, will cease working with FF 53.
The Mozilla team simply does not care. I'm on the verge of exploring alternatives based on the older Mozilla code, or just compiling my own browsers.
I mucked about with the linker options, and I think that I have the libs linked. they seem to be working,

New libs, only.
ugh. PNG and JPEG loading do work, but only on the second and later attempts. Something is not linked right, or the libs are not loading when the first instance of loading a file is called.
