Nabigatzaile lehenetsiaren agentearen atazak egiaztatzen du noiz aldatzen den nabigatzaile lehenetsia { -brand-short-name }-etik beste batera. Aldaketa baldintza susmagarrien pean gertatuko balitz, erabiltzaileei { -brand-short-name }-era bueltatzeko eskatuko zaie, ez birritan baino gehiagotan. Ataza hau automatikoki instalatzen du { -brand-short-name }-ek eta berriro instalatzen da { -brand-short-name } eguneratzean. Ataza hau desgaitzeko, eguneratu "default-browser-agent.enabled" hobespena about:config orrian edo { -brand-short-name } enpresa-politikaren "DisableDefaultBrowserAgent" ezarpena.

The Default Browser Agent task checks when the default changes from { -brand-short-name } to another browser. If the change happens under suspicious circumstances, it will prompt users to change back to { -brand-short-name } no more than two times. This task is installed automatically by { -brand-short-name }, and is reinstalled when { -brand-short-name } updates. To disable this task, update the “default-browser-agent.enabled” preference on the about:config page or the { -brand-short-name } enterprise policy setting “DisableDefaultBrowserAgent”.
