Comment 0 for bug 1598592

After installing the FF DE I was not able to start the bundled firefox, the icon in the luncher was replaced with the FF DE's icon. Filtering applications by "Firefox" finds only the Developer Edition. The bigger problem is that when the Dev Edition is opened it seems that the other firefox starts in background too, because if you try to close the window of the DE you will get notification "Are you sure you wish to close all tabs" (or something like that) but only one tab is actually oppened. Both editions have complete sync enabled, not sure if that is not causing the problem.
Other thing is that the checkbox for "Allow Firefox Developer Edition and Firefox to run at the same time" does not remember unchecked state. I am un-checking, closing the tab, opening preferences again and the option is active again (checked).
It should be possible to use different editions separately as on windows.
