You can hide the top toolbar in Microsoft Teams when sharing the screen.
To hide the top toolbar, you have to:
1. Click somewhere in the toolbar (not on the buttons)
2. Press
Ctrl + WThis will hide the toolbar, so you should be able to better work with tabs in your web browser. Instead of the big toolbar, there will be the small bar containg only the "Stop sharing" button. The small bar should not overlap the tabs as much as the big toolbar.
