because WebDialogs are not using the default browser installed on the user machine, but instead a Internet Explorer shell (the same that you see when viewing .chm files for example) on Windows version.

there is no option to use other browser engine for displaying WebDialogs.

btw, why do you need another one ?

Just another point on this issue since this was the only thread I could find that was related somewhat to my problem. I was using the get models button to access 3d warehouse for the longest time, no prob. Then one day the model images would not appear in the popup browser and I couldn't download them to my sketchup model. I tried restarting SU, rebooting the computer and eating some chicken soup...all to no avail.

Since I use FF as my default browser I assumed that SU was using it in some weird form as the get model popup. I now know that it uses IE, and was able to solve the problem by locating my deleted version of IE and purging all the cookies and caches. Too bad we can't choose to have FF used as the default dialog. Would be less confusing in certain instances.

cheers...
