Identify the extension and website
Start with the name of the installed extension and the public domain where the symptom occurs. Do not install an unfamiliar extension just to diagnose an existing player. Browser extensions can have substantial access, so review the actual installed item rather than assuming that all tools with a similar name have the same permissions.
Inspect its details
Open Chrome’s extensions management page, choose the extension’s details and read its site-access options. Google documents choices such as access when selected, on specific sites or on all sites for eligible extensions. The options shown depend on the extension’s permissions. Record the current setting before changing anything.
Keep the comparison narrow
If you decide to test the extension’s effect, change only its access to the relevant site or temporarily disable that one extension using the documented control. Save page work before reloading. Repeat the same failing action once. A result is more useful when the browser, programme and other extension states remain unchanged.
Recognise the scope limit
Google notes that site-access changes do not affect extensions using lower-level VPN or proxy access in the same way. A site-host permission switch therefore cannot be assumed to remove every possible influence of every extension. Read the extension’s own description and permissions before interpreting a negative test as proof that it is unrelated.
Restore or make an informed choice
Return to the original state after the diagnostic comparison unless you deliberately prefer the new permission scope. If the result changes, report the extension name, version and tested scope without sharing private account URLs. Avoid turning every extension off permanently based on one observation; narrow the explanation to the change actually made.
Questions, answered
Do all extensions offer the same site-access choices?
No. Their requested permissions determine the available controls.
Does a host-access change neutralise a VPN or proxy extension?
Google documents a limitation for extensions with lower-level VPN or proxy permissions.
