What you describe seems to indicate that Internet Explorer is currently set as the default web browser on your windows machine. This is most likely an operating system (computer configuration) issue rather than a WordPress problem. Change the default web browser on your operating system to Chrome instead of Internet Exploder.
Just to clarify –
Each time I open it , it runs with windows explorer
Do you mean it runs with Internet Explorer? (which was my initial assumption) or it actually just opens in Windows Explorer to view the files, rather than starting a web browser?
[edit] I see what you mean now. You’re right, it ignores the system default browser settings. However; I did get it to work with Chrome as the default browser. The path you specify in the pms_config file needs to be the absolute path to the chrome executable on your machine. Line 25 in pms_config will end up looking something like this – be sure to include the quotation marks.
BrowserPath= "C:\Documents and Settings\your_user_name\Local Settings\Application Data\Google\Chrome\Application\chrome.exe"
This was tested on an XP machine, so the path will be a little different on a newer OS. The quickest way to get the correct path for your user account, is to right click on the Chrome shortcut and view properties. Copy the path that’s listed in the “Target” box in the properties dialog. That will be what you need to place on line 25 in pms_config.
Thanks, it now opens in chrome and I can use firebug.
thanks! its working in chrome now!
