@christopherklay you can and I can, and I bet @downey can as well. But many users are simply lost at that point. Furthermore, if faking the agent does the trick, the blocker was entirely unnecessary.
And as for "using multiple ones": I do that for multiple reasons. One of them is "compartments" (yes I know "container tabs", but what's in different browsers is an entirely different beast).
@IzzyOnDroid @downey I completely agree that the blocker is pointless to begin with.
My point is mostly that simply having a user agent switcher installed that solves any of these issues down the line, is the easier solution compared to opening the page in a different browser every time it happens.
After all, the majority of people isn't running multiple ones, or is even logged in (if needed) in a second one.
