### WARNING: This is expected to not work on API versions prior to 2.11 and attempting it will break your passbolt.

The v4 browser extension is NOT compatible with versions older than 2.11.

If you are running an API version older than 2.11 you need to [perform an upgrade](https://help.passbolt.com/hosting/upgrade) on your passbolt install **FIRST** to API version 3 or higher.

If you are reading this after breaking your passbolt, reinstall the previous v3 extension [as described here](https://community.passbolt.com/t/passbolt-extension-chrome-notfounderror-after-v4-upgrade-testing-from-2-7-1/7405/8).

Edit: API versions older than v3 are reporting breaking results. (v2. 12.x, etc) Update to API v3 first.
