Advisory flags Facebook in-app browser cookie glitch, urges users to open links externally

An online advisory has warned that Facebook’s in-app browser is intermittently failing to send cookies that were previously set, disrupting access to some websites. The notice describes the behavior as a browser defect and says it is expected to be addressed soon.

Until a fix arrives, users are advised to keep using the Facebook app but avoid the in-app browser by opening links in the device’s default browser instead. The advisory outlines how to enable the “Links Open Externally” option within the app so that webpages load outside Facebook’s embedded browser.

For those still encountering issues, the guidance also details how to ensure cookies are enabled across common browsers. It references steps for legacy Internet Explorer versions (7–9), Firefox, Google Chrome, and Apple’s Mobile Safari on iPhone and iPad, generally advising users to allow first- and third-party cookies and permit local data to be set.

The advisory indicates the underlying issue appears to be a defect in the Facebook in-app browser and suggests that a correction should follow in an upcoming update. In the meantime, it recommends using the device’s default browser to avoid interruptions when accessing links.
