If one browser stops reaching KeePassXC immediately after another was connected, inspect the association names before changing website passwords. A connection is a relationship between a particular browser and a database; a convenient generic label can accidentally replace one you still need.

This workflow follows the KeePassXC 2.7.11 Getting Started guide. Identify the two browser installations or profiles and the database each should use. Give them distinct descriptions in your notes, such as office-firefox and laptop-chrome, without including secrets in those names.

Create a distinguishable association

In KeePassXC's settings, enable Browser Integration for the intended supported browsers. Unlock the correct database, open the KeePassXC-Browser extension and choose Connect. At the association prompt, provide a unique connection name before choosing Save and allow access.

The official guide warns that reusing a connection name in the same database overwrites the previous browser connection and prevents its access. If you are repairing an affected browser, reconnect it with a distinct name rather than repeatedly assigning the shared label that caused the collision.

Check the database identity in the process. A browser connected successfully to a different open database may still fail to offer the entry you expected. Record which browser was paired to which database so that the second half of the test has a clear target.

Test the original and new browser independently

Return to the first browser and inspect the extension's connection state. Then do the same in the second browser. The guide distinguishes a disconnected application, an extension unconnected to the current database, a locked database and a ready connection; treat those as different observations.

Use a harmless saved test entry where appropriate, stopping before any form submission. Confirm that the expected entry is available from each intended browser. Do not relax access for unrelated websites simply to hide an association problem.

Lock the database and confirm that both browsers reflect that boundary, then unlock it and repeat the readiness check. This tests whether the two associations coexist rather than whether only the browser you most recently configured works.

Keep the names with the device or profile inventory for future maintenance. When retiring a browser, review its association deliberately. The successful result is two identifiable working connections to the intended database, not a sequence of repairs that alternately disables the other browser.
