I'm sorry if I came across as rude. It was not my intent. Can you help me understand what specifically came across that way? I would appreciate it very much. I would agree it's probably a small percentage of users who use it, but I don't think that's a good reason to drop support. If software only kept features used by a substantial number of users, SharePoint wouldn't allow exporting lists to Access databases, Excel wouldn't allow pivot tables, and so on. I think there's a cliché about how 80% of Word users only use 20% of its features... but it's a different 20% for everyone. As a result, adopting such a principle would lead to truly disheartening results. Will Firefox perhaps completely drop support for PIV tokens next? I am not familiar with Firefox's architecture, I've only compiled it from source 2-3 times and only one of those times was setting up my own build environment (as opposed to a compiling package system). I've never hacked on it to any degree beyond the most trivial. So I could very well be wrong... but... I suspect it has not been very expensive to maintain, given that the protocol is simple and I believe has not changed in many years.
