no, the problem is that sites can _afford_ to block firefox, because their share is low enough that they can take the hit.
What we need to do, as tech evangalists, is to push the marketshare of firefox higher, so that they cannot be ignored by sites, due to significant traffic. This is how the open internet can preserve both privacy and control of the computing environment.
if your friends and/or family isn't using firefox (this includes mobile), nag them to switch. If you are a tech support for your extended family, push firefox onto them (and install adblock while you're at it).
If you control a company's IT infrastructure, push firefox as the default browser, over chrome.
The internet is repeating the microsoft IE days with chrome, but without the shittiness that made chrome a possible barrier breaker (chrome is good enough that most people aren't complaining).
