For me extremely relevant. And that probably explains a lot of my perspective. I'm one of those 'free software all the way' types and FireFox is a very important component in that toolchain.

Of course, being more or less forced into Gmail and Google docs (or office 365) means that that too is now a losing battle but I hope to fight this rearguard as long as I need to be commercially active. Frankly, I can't wait to shut down my email account and call it a day but it's still some years away.
