Disabled it and still no luck. Tried to manually edit the list in settings and that failed. Same issue with weather.gov. Needs to be a canned list of safe sites one can import. No issue with CapitolOne.com or Fidelity.com or most of the medical portals I access.

The update to Opera One(version: 126.0.5750.18) (arm64 did not change this situation. And a direct bug report to Opera has not been answered. BTW, geolocation on sites like https://radar.weather.gov/ does not work either.

Your version of MacOS: macOS Tahoe Version 26.2
Your version of Opera: System:macOS Version 26.2 (Build 25C56) 26.2.0 arm64 Chromium version:141.0.7390.125

A description of the problem, including as much as information as possible

Steps to (try to) reproduce the issue: Login with credentials via LastPass.

Expected behavior and actual one: Expected – Login.
Actual – Spins and returns to that page.

Login works via Firefox (which I'm trying to abandon in favor of Opera) and AmEx app on my iPhone.

LastPass is the only extension installed. No VPN. Other logins such as my bank, medical portals, and financial services all work.
