Lit tabs when activity is observed
I've tried Vivaldi during one week, and I've switched back to Firefox because of a very simple problem…
I need to connect to Google Hangout on two different accounts (personal and professional), so I don't use the extension but two pinned tabs. It works perfectly, but when I receive a message I only get the sound alert. It means that if I a not in front of my computer, I need to check the two tabs when I return to see if I have new messages.
On Firefox, the tab is lit when a message is added - that's extremely efficient.
Good luck !
Switching to active tab when receiving a notification is a missing feature and already reported bug.
