Install uipath extension for Firefox
Check browser type property of attached browser
activity or make selectors generic as possible you can.
Make sure before call this workflow browser in same page as you set selectors for attached browser activity
I got some problems with applications that are automatically runned as admin. Maybe you can try running UiPath Studio as admin and then try to attach the firefox.
Otherwise i would restart your computer. Sometimes UiPath just bugs and after a restart everything is working fine again.
you have to run your uipath studio application as admin. so go to your programms and right click on uipath studio --> more --> run as admin
can you send me a picture plz ?
oh yes, i did that
