You may not realize it but you can change the browser used by System Manager v3. It defaults to using Internet Explorer. Many companies lock IE down so hard with Group Policy that it breaks System Manager. To change it perform the following.
1) Launch System Manager. Once up, do not login to any of your controllers.
2) In the upper left, click Tools > Options.
3) In the Browser Path section, enter the path to the browser you prefer and click Save and Close. Launch System Manager again and it will use the new browser.
4) The browsers I’ve tested are as follows on Windows 7 x64.
C:\Program Files (x86)\Opera\launcher.exe
Firefox 26 (OCSM 3.1RC1 is buggy with this version of Firefox)
C:\Program Files (x86)\Mozilla Firefox\firefox.exe (for x64)
C:\Program Files\Mozilla Firefox\firefox.exe (for x32)
