I have developed my tests in FF as I prefer the locator assistance it provides so I know my tests would select a newly opened tab as the result of a clicked link in the past.
For the last few months, I have not been able to get this to work. The test case stalls until I stop it, never times out.
I am using FF 82.0.1 and Katalon Recorder 5.3.1.
All test cases work just fine in Chrome. Any thoughts on why FF is causing an issue with this now?
Edit: Sorry - I just realized you’re talking about Kat Recorder.
Two things…
Upgrade your Katalon - 5.x is a long way behind.
Firefox profile settings determine how links are handled. I think the default is to open them to a new tab. Then you would need to use switchToWindowIndex or similar.
Lastly, I use FF routinely. Like you, I prefer the DevTools in FF. I don’t have issues like you describe - switching windows/tabs works fine.
