Extensions

Browser extensions that mind their own business

Small, useful extensions for Chrome and Firefox. Each one sees a page only after you click its button, and none of them can send anything anywhere.

What we've built

Table Export

Chrome & Firefox extension

Exports any table on a page as CSV, JSON or YAML. Hover a table and click the download icon, or pick one from the list, then preview it, choose the rows you want, and download or copy it. It skips page clutter like pagination and filter rows, fills in merged cells, and keeps spreadsheet formulas from sneaking in through the data.

It can:

  • Read the page you're on, after you click its button
  • Save the file you export
  • Remember your format and options, in your browser only

Word Count

Chrome & Firefox extension

Shows how long a page takes to read. A ring fills as you scroll and counts down the minutes left, next to the word, sentence and character counts and the time it takes to read aloud. Select some text to count just that. It counts the article itself, not the menus and comments around it, and handles languages written without spaces.

It can:

  • Read the page you're on, after you click its button

How they protect your privacy

These extensions collect no data. They have no analytics, no accounts and no servers, and they're built so they can't send anything anywhere: every page they show blocks all network requests. Anything they read stays in your browser.

  • Only after you click. Installing one gives it no access to any website. It can see a page only after you click its toolbar button on that page, and only that tab.
  • "Always on" is one site at a time. If you want an extension to start by itself on a site you use a lot, you can turn that on in its panel. Your browser asks you to confirm, naming the site, and it covers that site only. You can turn it off from the panel or in your browser's extension settings.
  • Settings stay in your browser. The few choices they remember, like your export format, are kept in the extension's own storage, which websites can't read.
  • Nothing is hidden from you. In Chrome, the confirmation for "Always on" is a page websites can load, so a site could tell that one of these extensions is installed, though its address changes every session to make that hard. In Firefox, no site can load any part of them.

Links from the extensions to this page don't tell us which page you came from.
