dear purism forum folk,
i am using firefox 91.8.0esr on two different computers. on my librem 13 running debian i have no trouble logging in to this site (forums.puri.sm). on my librem 14 running pureos byzantium, i have trouble with my usual profile but no trouble if i make a fresh firefox profile (which is how i am sending this message). here are the symptoms of the failure:
- i click on “Log In”. up pops the login dialog. i enter my username and password. i click on “Log In”.
- a pink bar appears near the top of the login dialog that goes all the way across the dialog. there is black text in the bar saying “Unknown error”.
- the only thing i can do is dismiss the dialog and then i am back to the site but not logged in.
- in the browser console there is a failed POST request to https://forums.puri.sm/session. the response code is 403 forbidden. the response body is the json string “BAD CSRF”.
pictures below. help?
