Are you saying that the login windows never pops up for you upon clicking on the Add JotForm Tab button?
I have tested this within several browsers on my end, and it appears to be working fine. This was in Chrome:
And this was in Firefox:
As it appears to be working fine on our end, I believe it might be caused by a browser extension (such as ad blockers or popup blockers), or some other configuration setting of the browser. Can you please try again, and if you still experience the issue, please try disabling your browser extensions to see if that was indeed the case.
I would also like to ask you to please try it on a different browser as well, and see if it works for you that way.
If none of that helps, please let us know the version of the browser and which operating system you are using, so that we can further check such a configuration on our end. We will await your response. Thank you.
