What would you like to do?

depressing_tab_count Web Extension

A simple chrome extension that lets you know how many tabs you have open... you probably won't be pleased...

Also counts how many windows you have open, because it can.


Get the code. Either:

  • Download this gist as a zip and unpack it
  • Grab the tab_count.html, tab_count.js, and manifest.json files and put them in their own dir


  1. Open up chrome://extensions in your browser
  2. Make sure Developer Mode is enabled
  3. Click Load unpacked extension... and point it to a directory where the code you downloaded lives.
  4. Click the button that has the puzzle piece on it (I was too lazy to make a better icon)
  5. Cry 😭


  1. Open the directory with the downloaded code from above in a terminal
  2. Zip the contents up: $ zip -r -FS ../ *
  3. Open up about:debugging in your browser
  4. Click Load Temporary Add-on... and point it to the zip you just created.
  5. Click the button that has the puzzle piece on it (still too lazy to make a better icon)
  6. Weep 😭
