They were ahead of the game with extensions, then they destroyed their own extensions. They copied everyone else, not the other way around.

They were ahead of the game with tabs. Then while destroying their extensions they made vertical tabs harder, while still leaving it as a charitable contribution by the community instead of an internal project, and slow-walked it for a decade. I still have to do weird CSS to make them look right, because they decided to have an opinionated sidebar for no particular reason.

This, again, is not their fault. It's because of a man who they don't pay, who has had to battle with them on multiple occasions. Their only contribution is not accepting a Chrome standard completely. Imagine wanting to be given credit for not exactly copying your neighbor, after an enormous amount of pressure was brought to bear. It's my belief that Google decided that Firefox wouldn't kill ad blocking in the end, because it would have looked horrible in antitrust court. Now that's over (Obama judges don't believe in antitrust), and you can expect Firefox to kill it soon enough.

Nah. They kept telling me, while ignoring everyone's complaints about their actual experiences, that the most important thing was to reduce startup time for some unknown reason.
