As you can see in the image (URL), when I put my cursor in toolbar to the right on Roboform icon, the <> above and part of the left icon are 'highlighted', and when I click the Roboform icon, <> executes.
I do not know when this happened. I just updated to FF v. 100.0.1
Oooops, just updated to v 100.0.2, and <> disappeared. Thought the problem was solved, but no. When I now click the Roboform icon, <> still executed (expanding FF window).
What can I do, should you know?
