browser interventions, 2026 @ online
inversions of online systems by firefox userscripts ...
browser scripts (and local performance devices) for making hidden online systems visible, audible, and bodily.
beginning with one simple rule ... like a tracking pixel, a cookie, a reputation score, a recommendation system, a step count, or a background network request each script performs a inversion. an invisible platform metric becomes a tiny bodily rule. a simple rule becomes a social machine.
alongside the browser scripts are local performance devices that extend these inversions into (online) endurance performances. where for example step counts and physical movement become forces within the computer... they allow the amount of clicks, scrolls and focus.
the body is monitored, but the data is not used to optimize productivity, improve a profile, or make behavior more legible to a platform. it is translated into something that changes pace, limits, sounds or finds a reason to continue.
the browser is never neutral window. these scripts expose some of the systems (within this moment of time) that organize attention, market value, identity and movement.
the metapixel portal makes meta tracking visible through growing blue pixels on sites using the meta pixel. each pixel reveals tracked data, triggers sound, and can portal you between meta-enabled sites you have visited before.firefox userscript
touch grass turns my step count of yesterday into today’s click allowance. the grass disappears as you click, blocking clicks at 0.
v2 turns my current steps into the allowance of today’s clicks.

v3 is a local performance tool that turns your steps into live computer actions: clicking, advancing slides, or influencing scrolling speed. your phone displays a step count connected to my computer through a private esp32 wi-fi network. iphone safari + local motion-sensing webpage + esp32 private wi-fi + mac with local https server + hammerspoon

pronoun leaker is a browser script that (randomly or intentional) swaps pronouns in website text, shifting gender experience online.

diagram + research by nina - inspired on talk post mysticism symposium, soloshow - find website on lurkers here.

the reddit karma spiral turns the “karma decay” diagram by nina into a browser instrument showing your states between participation and terminal lurking.
as you lurk, read, click, vote, and scroll, one dot spirals inward with your consumption while a second moves outward as your behavior becomes more legible to the platform shifting through different layers of noise sounds. posting or commenting resets your descent... passive observation, hesitation, reputation thresholds.
