Hi, I am trying to switch to Mozilla due to IE6 being extremely buggy, especially when working through proxy servers. We are currently developing a Zope/Plone application which uses standard Zope authentication using an acl_users folder. To test this application I need to open a browser window onto it, loged-in as a user, however at the same time I also need to have another browser window open onto the ZMI logged in as a manager user so that I can edit the Scripts/ZPTs. Doing this in IE6 is simply a matter of starting up 2 intances of it (ie. Not clicking File->New->Window to open the 2nd window). This seems to keep the authentication info. seperate. I realise that this is a bit off-topic as it is more of a general web-browser question but I was hoping that some Zope users have had some experience using Mozilla during application development.
