    You can also run the plugin as a standalone app. I posted this on a vmware board.

    Run ~/.mozilla/firefox/we7cdezi.default/extensions/ and then point it to the tomcat instance. Mine is localhost. Login and you get a list running virtual machines. Click one and login. Create a shortcut to the plugin and you can just double-click it like a normal app. Change we7cdezi.default in ~/.mozilla/firefox/we7cdezi.default/extensions/ to what ever your profile is.

    I found that the display in the console would not update properly on occasion. I’m not certain if this something that is unique to my configuration or not. For my Windows vm I’ve started using rdesktop instead once its running. I can’t dynamically resize the resolution by resizing the window like I can with the console 🙁 , but I just run rdesktop with a custom resolution and clipboard integration. “rdesktop -g 1270×993 -N -a 16 -x b -P -5 -r clipboard:PRIMARYCLIPBOARD -r sound:remote”. Create a shortcut and just double click. Obviously the console is still needed at times.

    Nice find. I appreciate your post.

    Works fine for me too.

    However if you didn’t have Firefox v3.0.0 installed and vmware plugin first, then Firefox v3.0.1 won’t even let you install the plugin (and the install.rdf doesn’t exist).

    To get around this install Mr Tech’s toolkit plugin for Mozilla at:
    (for some reason I found I had to do a save as, then drag and drop the toolkit.xpi into my addon page)

    The above plugin allows the vmware plugin in be installed, then use the tweak described above. I modified install.rdf:
    which also works (and hopefully will still work for 3.0.2 etc)

    Finally I can test centos appliance (which starts without any connectivity).

    Firefox 3.0.3 seems to break the vmware plugin entirely. I use the ‘nightly tester tools’ to force the plugin install (which worked with 3.0.2), but now clicking on the ‘open console in new window’ causes no effect.

    Thank you – this worked a treat. I was stuck for a solution. I had shortcuts that worked fine for some of my VM’s, but others that I could not access through Firefox.

    I have the same problem with FF 3.0.3 any updates?

    Get Vmware server 2.0. It has updated client for FF 3.0.3

    How do you “point it at” the vmware server in order to get a list of available VM’s ?
    I always get ” Missing server name or connection configuration file name.” every time I double click the shortcut!!

    I had the same problem in FF 3.0.5 and running vmware server 2.0 on a remote machine. The issue was that I had a previous version of vmware server 1.x installed on my local machine so the Firefox plugin was outdated. I uninstalled the plugin in Firefox from Tools>Addons and then connected to the remote vmware server again. Now when I fired up the console it said “missing plugin” and automatically downloaded the correct plugin from the remote computer. Now it works great.

    @Dave – When I vmware-vmrc, it first presents me with a dialog box asking for server, username and password. For server name, I use localhost:8333.

    Sounds like arguments are being passed when you run the shortcut? Have you tried running it from a cmd prompt to see if it behaves the same?
