Chrome's screen sharing function is the best among all the browsers.
Share Button is Grayed Out
This really isn't a problem with Chrome, but that it's not intuitive that you have to select one of your screens/tabs/applications first:
Start screen share
Click on one of the options in the tabs: Your Entire Screen, Application Window, or Chrome Tab
Now, select one of your screens, application windows, or Chrome tab, and THEN the Share button will light up.
On a Mac: when choosing the screen, window to share, the thumbnails to choose from are grayed out
This is likely a permissions issue. Try the following:
Bring up System Preferences on your Mac
Go to Security & Privacy
Click on the Privacy tab
Find "Screen Recording" on the left.
On the right, see if "Google Chrome" is checked.
If not checked, check it! You may have to unlock this panel to make changes!
