Login Button Opens Nothing? Check a Blocked Sign-In Window
A sign-in flow may need a new window; allow it for the trusted site instead of disabling all pop-up protection.
Click Login once and look for a blocked pop-up icon in the address bar. If the site is trusted and you expected a new sign-in window, allow pop-ups for that site only, then try again. If no icon appears, the website or an extension may be stopping the flow.
See whether a new window was blocked
Some services open their identity provider in another browser window. Edge and Firefox show an icon or information bar when their pop-up blocker catches one. Click the sign-in button once, inspect the address bar, and note whether a new window appears behind the current browser window.
- Confirm the login page belongs to the service you intended to use.
- Look for a blocked-window notice in the browser.
- Check whether the site displays an inline error instead of opening a window.
Allow only the site that needs it
Microsoft Edge and Firefox both support site-specific pop-up exceptions. Add the service’s exact website to its allow list and retry the sign-in. Keep the global blocker enabled. If the new window comes from a different sign-in domain, read the destination carefully before entering a password.
A browser extension can also block a sign-in dialog. Temporarily test the site in a clean profile if the browser itself reports no pop-up block.
If the browser was not blocking anything
Try the site’s direct login page or its app status page. Clear a stale sign-in attempt by closing the unfinished window and starting again. If the issue happens across browsers, capture the page’s exact error and report it to the service rather than changing security settings blindly.
A surprise sign-in window on an unrelated site may be a phishing attempt. Site-specific permission is for a trusted, expected login flow.
