Created attachment 8439954 [details] firefox_winxp_appurl_bug.PNG User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release) Build ID: 20140610163407 Steps to reproduce: 0) Hello, I experienced this bug while working on an application for my company. I believe this is a generic issue that could affect any application using the same mechanism as we do 1) You need to have dashlane software installed (I'm a QA engineer at this company, go to www.dashlane.com to download this software) 2) Go to the following app url: dashlane://team/emergency#origin Actual results: Firefox prompts for authorization, the prompt contains a weird and very long string wich makes the pop-up abnormally large (it doesn't fit the screen). Expected results: There should be no such string in the pop-up. Text should stop at "[..]Dashlane.exe %1"
