Installation and optional access differ
Mozilla documents optional extension permissions for added functionality and allows them to be reviewed in the extension’s permissions details. An installed extension therefore does not necessarily have every optional capability enabled. A missing feature can require that specific permission review rather than proving the extension file is absent or damaged.
Read the requested purpose
Check the extension’s actual publisher and explanation for the capability. A permission request should relate to the function you intend to use, not merely to an unrelated player error that appeared nearby. Do not accept broader access automatically because the extension name is familiar or because another feature already works.
Compare the exact function
If an intentional permission change is appropriate, note the original state and test the one feature concerned. Avoid changing several unrelated toggles, reinstalling the extension and clearing browser sessions in the same attempt. Several simultaneous changes can improve the result while leaving no clear evidence about which one mattered.
Use the right support boundary
If the optional permission is unavailable or the explanation is unclear, consult the extension publisher. If the website returns an account or programme error after the extension function succeeds, retain that as another stage. A precise report identifies the requested permission and affected function without exposing private page data or a complete signed media address.
Questions, answered
Does installing an extension automatically enable every optional permission?
