Follow these simple steps to install the BUY Sim extension on Firefox.

Installing on Firefox (The "Hacker" Way)

01
Grab the XPI

Download the Firefox extension file from your secure dashboard.

Go to Dashboard
02
Install It

Go to about:addons, click the gear icon ⚙️, and choose Install Add-on From File....

⚠️
"It says Unverified!"

If Firefox blocks it, you need to use Firefox Developer Edition or Nightly and:

  • Go to about:config
  • Accept the risk (live a little!)
  • Search for xpinstall.signatures.required
  • Double-click to set it to false
