Short answer, disable the Java plugin and you can do it. > No, I'm not saying that. > > The User Agent Switcher works - it just happens to trigger a bug in > Firefox if you quit Firefox without having the User Agent Switcher set > the prefs.js variable "general.useragent.override" to something > starting with "Mozilla/X" for any X >= 5. Then Firefox won't start > until you modify prefs.js manually with an editor, and the error > message Firefox gives could be a little more explicit pointing to the > error. > > It doesn't matter whether you set the variable with the User Agent > Switcher or whether you do it manually with "about:config". > > The name of "general.useragent.override" implies this is an override > variable supposed to be set to any value which make sense to form a > HTTP request with, but Firefox requires a certain restricted value set > to be able to start up. > > I can't conceive a reason for Firefox to internally depend on the user > agent string it sends to HTTP servers, so this Firefox behaviour > sounds like a bug to me :) > > Two possible remedies: > > a) To make sure that Firefox doesn't internally do stuff with the > user agent string and get rid of the check. (preferred) > > b) To make the startup error message a little more specific, pointing > to "User Agent" values set in "prefs.js". > > Does this answer your questions so far? -- Eric Dorland <[EMAIL PROTECTED]> ICQ: #61138586, Jabber: [EMAIL PROTECTED] 1024D/16D970C6 097C 4861 9934 27A0 8E1C 2B0A 61E9 8ECF 16D9 70C6 -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS d- s++: a-- C+++ UL+++ P++ L++ E++ W++ N+ o K- w+ O?
