Quick nit: that headline should read "What If...It WERE Easy to Write Firefox Extensions?" due to the subjunctive mood of the verb.

The subjunctive mood is dying pretty quickly, along with "whom" and "shall". "If X was" is already used quite commonly in hypothetical constructs, even among native english speakers. Yes, technically, "if X was" is a question about X's past, not a supposition about X's future, but english is "as she is spoke" :)

Another generation or two, and it'll be gone. No use crying over linguistic evolution. Static languages belong in the dustbin of history, and that's where they eventually end up.

As High Lord of the English Language, I'll allow the use of past tense here.

Nit acknowledged. I actually originally wrote the headline that way, but decided to preserve the Aza's original.

What If... instead of writing a blog post, you started writing a library to make it easier?

Talking accomplishes nothing. Write some code.

Aza works for Mozilla. He hints that he is, in fact, writing some code.
