As mentioned by others, the extension does not seem to work anymore.

After installation, the extension popup just keeps searching for credentials for the current page, but never finishes.

Does not work because the bugmenot website does not send CORS headers:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https:// bugmenot.com/view/x. (Reason: CORS request did not succeed).

The extension is stuck on loading, do not display any credential. By going directly to bugmenot website there are credentials for the website i want creds.

Not working.

Stuck in loading.

Only gives expired/old/invalid logins unless you pay.

you can only see two entries without paying for it, and it wont even let you vote on things to improve the site for other people, so this add on is unfortunately worthless.
