Firefox probably won't help with non-browser software, if that's what the parent comment was referring to. I also have to develop an app for a client for XP because of some proprietary hardware that still doesn't have a Windows 7/8/10 driver.
Yes this is my problem. The hardware manufacturer does not want to support upgrades (they want to sell new hardware) and so I am stuck supporting XP.
In my situation there is not even hardware the customer can upgrade to as the original hardware supplier has left the market. We are all stuck with XP until something catastrophic happens.
I know a chemist still stuck with a windows 98 machine for a similar reason (it's the most recent OS that a particular piece of lab equipment has a driver for).
The problem is for an individual lab the cost is very high - there needs to be some sort of forum where labs can get together and put a bounty together for new drivers.
