Does this mean that the FTP server will now offer a choice of:

1) Firefox without DRM, without lockdown

2) Firefox without DRM, with lockdown

3) Firefox with DRM, without lockdown

4) Firefox with DRM, with lockdown

...for every language?

I don't know if they'll offer each permutation of all those possibilities. I don't see why not though, it's just a little more build time.

In any case, if the specific combination of features you want is missing, the option to build from source is always there. (At least on Linux, building Firefox is also pretty easy.)

AFAIK, yes, that is the plan.

However, "without lockdown" is going to be an "unbranded browser."

So likely you will see two folders, something like this:

/browser/release/

1) Browser with DRM (no lockdown)

2) Browser without DRM (no lockdown)

/firefox/release/

1) Firefox without DRM

2) Firefox with DRM

That doesn't sound like an option that will fork for my use-case - I manage a bunch of Windows machines; if we upgrade Firefox to "Noname Browser" with a different icon, the users will be confused and unable to find it.

They said previously the unbranded non-lockdown beta/stable releases would be enUS only.
