EFF is basically Walter Sobchack in this scenario to Mozilla's dude.

EFF: Has the whole world gone crazy? Am I the only one around here who gives a shit about the open web? Dude. This is it. Let's take that hill!

Mozilla: what's the point, man? why should I die on this hill?

EFF: it's a fucking important hill dude. Unchecked DRM aggression.

Mozilla: what about my browser market share?

EFF: What the fuck are you talking about? Browser share is not the issue here, Dude. I'm talking about drawing a line in the sand, Dude. Across this line, you DO NOT...

Mozilla: Well, the problem is... They're gonna kill my browser share! Man!

Donny is the open web I guess. His death was predestined by circumstances and certainly not the Dude's fault. Also, I think it would be best if no one tells the EFF how DNS works.

Mozilla: Goddammit EFF, you fucking asshole. Everything's a fucking travesty with you man!

EFF: I'm sorry, it was an accident.

Mozilla: What was that shit about the open web? What the fuck does anything have to do with the open web?

EFF: Dude, I'm sorry...

Mozilla: What the fuck are you talking about?

EFF: Dude, I'm sorry...

Mozilla: Fucking... fuck, EFF.

EFF: Come on, dude. Hey, fuck it, man, let's go bowling.

I wouldn't switch to another browser just because Mozilla doesn't implement DRM. In fact that strikes me as completely the wrong reason to switch to another browser. Continuing to use Mozilla and boycotting services that use DRM is a more reasonable approach. The good news is there will likely be an extension and/or custom build of Firefox that removes the DRM. Of course this means we won't be able to watch the DRMed videos until someone cracks the encryption, but if we're boycotting them then that means we weren't going to watch them anyway.

The content providers start blocking firefox from accessing their content. It will eventually be easier to use chrome, IE, or whatever instead of using a work around to keep on firefox. It will lose a large portion of its user base and then its funding as it won't bring in as much from default search provider contracts etc

That's even more of a reason to boycott them and keep using Firefox.

But I want to watch my netflix without having to jump through more hoops than I do already (running it on Linux).

And I know my family who is not tech savvy will just have to move to a browser that allows Youtube, Netflix, and whatever else requires this DRM.

I don't like it but I don't think firefox would make it otherwise.

There is no simple answer. The only thing I can suggest is to just stop using Netflix until someone cracks it, or they decide to stop using DRM. This isn't your fault, it's Netflix and Hollywood's fault, their use of DRM is blackmail on their entire customer base. As in the case of any blackmail, the best option is to stand your ground and not give in.

But... Mozilla IS irrelevent without it's differentiating principles.

Microsoft sacrificed backwards compatibility with Vista and look where that got them...

Or, by forcing developers to provide a DRM-free alternative Mozilla would bring about a competing technology that would at a later date come to dominate and kill the DRM proposal.

The problem is not that there's no DRM-free alternative, it's that major content owners would prefer no HTML5 solution to a DRM-free HTML5 solution. There is literally nothing Mozilla can do about that. People who want to do DRM-free HTML5 video already can, but that's not the problem.
