GET /content/ HTTP/1.1

am seeing an issue in firefox on unix with accessing a web page which uses basic http authentication mechanism. It pops up for user id and password for basic authentication. When I enter the credentials and click submit the response received is 401 Unauthorized. Same webpage and authentication works in chrome browser on same system (so assuming no firewall issues). The Firefox and chrome is configured in a console where we test it. And both are requesting for the same host. I believe there is some configurations issue in Mozilla firefox that might be affecting it. Attaching the request and response for both. Firefox version that has a problem : Mozila Firefox 78.4.0esr '''Request and response in Chrome''' ''Request GET /content/ HTTP/1.1 Host: 3.87.81.51 Connection: keep-alive Cache-Control: max-age=0 Authorization: Digest username="admin", realm="Power Xpert", nonce="16981e9013fd33c215fb54cfe5c8246b", uri="/content/", response="527760ce114bf839a9df342ba27ca352", qop=auth, nc=00000002, cnonce="572ab111183b3236" Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.101 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.9 Response - HTTP/1.1 200 OK Content-Type: text/html ETag: "1471035255" Last-Modified: Mon, 23 Jun 2014 19:17:18 GMT Content-Length: 7452 Date: Wed, 09 Jun 2021 21:52:49 GMT Server: lighttpd/1.4.28-devel-59460'' '''Request and response in Firefox''' ''Request : GET /content/ HTTP/1.1 Host: 3.87.81.51 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Language: en_us,en;q=0.5 Accept-Encoding: gzip, deflate DNT: 1 Connection: keep-alive Upgrade-Insecure-Requests: 1 Response: HTTP/1.1 401 Unauthorized WWW-Authenticate: Digest realm="Power Xpert", nonce="3743c840c84a56d1e56be155dc3284c1", qop="auth" Content-Type: text/html Content-Length: 351 Date: Wed, 09 Jun 2021 21:57:57 GMT Server: lighttpd/1.4.28-devel-59460'' The difference is : Below Authentication header is missing in firefox.
