Based on this thread, I think... everyone would question such an arrangement.
At the last company I started, a b2b saas, as of 5 years in, there were under 10 logged-in pageviews from Firefox. Ever. It's dead; the coyote is 50 feet past the cliff; and we're just waiting for gravity to appear.
Mozilla has also clearly given up on Firefox, though people get mad on here when you point that out. I just don't know why they're operating under the delusion that anyone will listen to Mozilla about privacy when everyone realizes they no longer build a browser that matters.
