This is a beta release. It is intended for experienced users who are comfortable installing extensions manually. Please report any issues via Telegram or email.
Step 1: Add-on for KeePass
Download and run the KeeForm installer. The defaults are fine for most users. You only need to do this once, even if you install KeeForm on multiple browsers.
After installing, make sure the extension is enabled — KeeForm shows a green indicator when everything is working. From now on, double-clicking an https URL in KeePass opens the browser and fills your login automatically.
