In Chrome, make sure you set your less frequently used extensions to run "On click" instead of "On all sites". Extensions -> extension details -> Site access.
For dev tools and such, I set a whitelist of the sites they're allowed to run on, using that same extension details page. There's no need for your JSON formatter etc. to run on every single page you visit. Also speeds up browsing.
