Feature Request: Could we get PaleMoon (or other browsers) added to the list of browsers?

I live in a world where there are still trolls hiding under bridges and watch towers with fire as the communication device...
We use older ssh/putty to connect to things, but that seems to be doable now in RDM.
We use PaleMoon to connect to these same older environments because they have not been retired and require Adobe Flash, etc. to function.

It would be nice to be able to add these PaleMoon connections to RDM.
I would think it would be a simple browser inclusion,full support of fields would be nice, but not necessary.
