Thanks for the report — a version note would help pin this down (ah's Adom menu → About shows it; our agents now include versions automatically).
What you hit: ah routes EVERY URL through the Browser Picker, which remembers a per-domain choice and has a 5-second countdown that auto-picks for AI-driven flows — so if the login window opened somewhere unexpected, the picker most likely auto-picked a remembered/default choice before you chose. Two asks:
- Update to ah 1.0.44 (the updater banner, or the wiki page installer) and retry the login flow.
- If it still lands in the wrong browser, tell us what the picker dialog showed (or screenshot it) and which browser you expected. Adom menu → Browser Picker Manager shows/edits the per-domain memory.
