Hi @andrzej.kniola,
Thank You for reply, I was automating some dynamic websites and was able to do so even in complex cases but before running automation I’ve needed to start Firefox profile manually and then do Attach Browser action inside automation.
There were no problems working with different tabs inside the same window in this case.
The problem is that UiExplorer can only identify Firefox as a browser if there is only one Firefox browser process running in Windows Explorer, if there are more Firefox processes running it will show all the others as applications. Therefore Your proposal doesn’t work here.
For example if to open two instances of Calculator in Windows Explorer it shows them as one process and in UiExplorer You can highlight any of two windows by using idx parameter.
