Decide whether stored site state is the question
A persistent login loop or stale preference can justify examining one website’s stored data. A problem limited to one programme may have another cause. Record the exact symptom before clearing anything, so the result of the reset can be compared with the original behaviour rather than becoming another untracked change.
Prepare to sign in again
Mozilla explains that cookies can hold login state and preferences. Clearing the relevant site can therefore sign you out or remove local choices. Make sure you know the legitimate sign-in route and can recover access before proceeding. Save unfinished forms or other work in that site. Do not copy passwords into a public support note as preparation.
Select the intended website
Firefox documents a current-site clearing action in the address-bar trust controls and a settings route for choosing specific sites. Use the current website action or search the site-data list for the intended domain. Read the confirmation carefully so a one-site task does not become an all-history, all-cookies or all-passwords deletion.
Reopen and repeat the original task
After the selected data has been removed, return through the service’s legitimate public address and sign in as needed. Use the same action or short sample that failed earlier. Note whether the login loop, preference or player state changed. A successful reset identifies a useful difference but does not prove that every future issue has the same cause.
Keep the evidence modest
Tell support which site’s local data was cleared and what happened after a fresh sign-in. Do not promise that clearing cookies repairs account billing, grants access or restores a removed programme. If nothing improves, avoid repeating a broader deletion without a new reason; preserve the result and move to the next specific diagnostic question.
Questions, answered
Can this remove a site’s remembered login?
Yes. Prepare for a fresh sign-in and keep the legitimate recovery route available.
Is clearing one site the same as erasing all browsing data?
No. Inspect the selected scope and confirmation before completing the action.
