What exists on Show HN
Never launchedOne Show HN launch does part of this. Nothing does the whole job.
Instead of: NoScript, Firefox
The idea, as matched
A browser or extension that lets me control per site which features run (JavaScript, cookies, WebGL, referrers, containers), with shared lists of the minimum each site needs.
Jev first matched 23 requests to this idea; a second reader kept 20 of 23.

Each line is an AI paraphrase of what the writer wanted. The link goes to their own words on Hacker News.
Reader’s note. Shared NoScript allowlists are the most specific repeat ask.
- Dec 2025Wants a NoScript-like extension using a public database to allow needed scripts and block everything else automatically. Read it: a comment in “Is Mozilla trying hard to kill itself?”
- Dec 2025Wants an extension that limits JavaScript to only what improves a website, the bare minimum for usability. Read it: a comment in “Is Mozilla trying hard to kill itself?”
- Jun 2025Wants a maintained replacement for an abandoned extension that controls referrer headers. Read it: a comment in “Dinesh’s Mid-Summer Death Valley Walk (1998)”
- Oct 2024Wants an extension or built-in feature to define container groups by domain patterns, always opened in isolated containers. Read it: a comment in “Poll: Do you use browser profiles?”
- Jul 2024Wants a browser where each browser or JS feature, such as fingerprinting, can be toggled individually. Read it: a comment in “Ladybird Web Browser becomes a non-profit with $1M from GitHub Founder”
- Sep 2022Would pay for a curated whitelist of domains for NoScript, instead of building their own slowly. Read it: a comment in “Ask HN: Do you browse the web with JavaScript disabled?”
- Apr 2021Wants an extension that blocks WebGL until clicked, like old Flash blockers. Read it: a comment in “Are top websites using WebGL for fingerprinting?”
- Feb 2021Wants a browser that configures features like WebAssembly, websockets and storage per domain, as Opera Presto did. Read it: a comment in “WebAssembly”
- Nov 2020Wants a Safari iOS add-in to whitelist specific sites for JavaScript. Read it: a comment in “Please disable JavaScript to view this site”
- May 2020Wants an extension that blocks JavaScript in unfocused tabs unless the domain is whitelisted. Read it: a comment in “Intel's flagship 10th-gen desktop CPU has 10 cores, reaches 5.3GHz”
- Apr 2019Wants a uMatrix equivalent for Safari built on content blockers. Read it: a comment in “Adblock Plus filter lists may execute arbitrary code in web pages”
- Mar 2019Wants an extension where users share allowed-script lists per site so NoScript presets itself. Read it: a comment in “Firefox 66.0 Aims to Reduce Online Annoyances”
- Aug 2018Wants a browser extension that limits site access to the history API. Read it: a comment in “How I recorded user behaviour on my competitor’s websites”
- Jan 2018Wants a list of the minimum required scripts for specific sites, tired of trial and error enabling. Read it: a comment in “Long-Term Consequences of Spectre and Its Mitigations”
- Oct 2017Wants a browser that isolates every website in its own sandbox, so no site knows about others. Read it: a comment in “Ask HN: Why does my credit union check if I'm logged into Steam and Reddit?”

- Dec 2012Wants a Firefox or Chrome add-on that strips referrer information from cross-site requests. Read it: a comment in “You’re not anonymous. I know your name, email, and company.”
- Nov 2009Wants an easy way to whitelist accepted cookies, like NoScript does for scripts. Read it: a comment in “Magic cookies mean the end of privacy on the Internet”
Building this?
Read ten of the asks above first, because they say what the existing launches miss. If you ship it, post it as a Show HN so the next run of this list finds it.
Ship it like Vercel, on a server you own
This site runs on ShipTiffin. A push to GitHub deploys it, the way it would on Vercel, but the server is a Hetzner box in your own account. Postgres, sign-in, email, jobs and analytics are already on it, every project gets a hard limit, and nothing is billed by usage.
$19 a month per box, plus about $10 for the server at Hetzner. Open source, so you can also run it yourself for free.
