Here is a link to a video demonstrating the problem.
In the video, first I show that adjusting the UI Vision RPA works properly in Chrome (with the rounded tabs). Then, I demonstrate the problem in Firefox.
In Firefox UI Vision RPA, when you try to adjust the vertical bar in the window, then the Save, Record, Step, Play Macro, and Settings buttons disappear. And the Table View and Source View tabs disappear.
I am hoping you will make UI Vision RPA work properly in both Chrome and Firefox for adjusting the window instead of working only in Chrome.
