What is hard about things like this is it ultimately boils down to self control.
Sure, by creating the friction tunnel, you are less likely to get distracted online, which makes self control easier.
But the thing is we are smart and computers are fast; meaning most software-based friction tunnels are quick to undo.
I did something similar to what the OP described by solely using the Mullvad Browser, which is in permanent incognito mode.
The moment this introduced friction in some nuanced way that I had not foreseen, I just switched back to my main browser as I could not think of a way to handle this edge case.
For me at least I think the friction tunnel needs to be inherently physical. Using an old computer (with a new one not in the same room) is a much better friction tunnel than changing your browser.
