In the end: Thank you for your comment : ) My annoyance with the plugin situation, and at first, no resolution for it, was fixed in 45: https://support.mozilla.org/en-US/kb/add-on-signing-in-firef...
I'm now running the latest version of FF, but still able to use my plugin.
Progress at what cost? Does maintaining security have to also mean breaking the systems that pay my bills?
I do not think you want to be paying your bills on a browser that's been compromised, no.
It's a dev box that only touches local resources.
