Trust self-signed printer certificates

Posted

I work in a position that requires me to log in to several printer web interfaces every day on a company intranet, and every time I pull up a printer's site Firefox shows me a certificate error. I know that this is because the printer is signing its own certificates, that much is obvious from the error. I want to know if there is a way to allow certificate errors for a certain sub-net or if there is a way to trust many certificates at once. I could potentially write some sort of script to capture all of the printer certificates, but then I do not know of any way to add those certificates to the Firefox exception store.

If it were only 20 - 30 printers then I would just load every printer interface separately. But I support an environment with ~2000 printers so that would not be practical. (10 - 20 seconds at least to trust each printer cert).

Check with your IT department on this as that is a internal settings and the Browser can't change that.
