I installed the extension but the Scanner still asks for it

The Scanner opens by itself once it sees the extension. If it still says Add the extension to open your Scanner, work through these in order.

1. Click back into the Plug Seller tab. It checks again every time you come back to it.
2. Press Already installed? Refresh.
3. Make sure you installed it in this browser, and in the same Chrome profile. The profile picture is at the top right of Chrome.
4. Open chrome://extensions and check that Plug Seller: Profit Analyzer is switched on.
5. Close the tab and open plugseller.com/scan again.

On phones, tablets, Safari and Firefox, the Scanner never asks for the extension and opens without it.
