So because a master password does not provide perfect security we should make do with no security?

You might as well argue (warning, car analogy approaching) that because a determined thief could easily break into your car you might as well leave it unlocked with your laptop on the back seat.

I would be willing to place a large bet that in any scenario that would allow me to recover Chrome or Safari passwords, I would also be able to recover firefox passwords that are locked with a master password, within a reasonable amount of time.

Maybe, but without a master password anyone with a passing knowledge of firefox could get a copy of all your passwords in seconds.

"The Google executive is being brought back because it's now been shown that most of the Google operations are based in London, not Dublin and he was therefore telling porkies."

The PAC are just trying to distract attention away from the fact that the tax laws that are being explioted were designed by incompetent politicians like themselves. You can't blame companies when they are following the law. If they are not following the law they should be in court, not before the PAC. As IamTheRealMike said in an earlier comment, this is a show trial.

Actually 150 chips not 150 euros (otherwise why bother to contribute at all, the cost will be the same either way).

"His Majesty's Declaration of Abdication Act 1936 (1 Edw. 8 & 1 Geo. 6 c. 3) was the Act of the British Parliament that allowed King Edward VIII to abdicate the throne ..."

The Act did not remove the monarch, it allowed him to abdicate.
