Just turning off your network interface for the duration of a work session (maybe do timed Pomodoro bursts) will guard against the mindless reflex of tabbing over to the browser. Then you get the opportunity to actually make a mindful decision about whether to go out of work phase and off browsing or not. If you get legit stuff to search that isn't completely blocking the offline work, write it down on a piece of scratch paper to look up later.
Tricks like this tend to stop working though. You'll probably just go into mindlessly bringing up the network interface instead in the long term, but even months or weeks of having a working technique are better than not having one.
Maybe you could team up with an Ita who works with the Reticulum and become an Avout who is forbidden from it.
Yeah, I tried this for a while, along with putting Chrome in increasingly obscure places on my hard drive. After these failed, I came upon the flash drive idea, which has the feature that it involves physical activity and therefore can't be done mindlessly. If you need to, you can throw it across the room.
