The password manager has stored the correct password and the password prompt screen is populated but the password prompt must be acknowledged to continue loading web page content. This has been reported in the past with Version 1.n. Works exactly the same with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1 firefox-3.0a3pre.en-US.win32 (latest branch from last night). Does not occur with IE6.0 SP2. Password is requires password once and never requests again. Reproducible: Always Steps to Reproduce: 1. At Corporate client with domain and internal proxy requiring authentication. 2. Select any web site 3. password manager prompts for password - stored user name and password are displayed but prompy MUST be acknowledged to proceed 4. password manager prompst many times AND it seems toconcide with each image displayed on the web page Actual Results: After acknowledging each prompt the web page displays Expected Results: Password for proxy authentication has been stored. Firefox should not prompt again. Occurs with no themes and no add-ins and on fresh install or when with add-in and themes. Found references in past versions to value in "about:config" network.automatic-ntlm-auth.trusted-uris needing to be set to proxy name. Makes no difference if proxy server name and port (calmainproxy.cal.riotinto.org:80)is set here.
