I use this feature selectively in Safari now, and am glad to see it in Firefox. Eventually I&#x27;m sure I&#x27;ll run into the problem of getting duplicate notifications from the same sites. I wonder what the solution for that will be... running only one browser at a time is not an option. Maybe I&#x27;ll have to keep track of and choose just one browser per site for allowing notifications.<p>Why have two browsers open at once? So that I can be logged into Google services simultaneously with two different accounts (personal and work). Off topic, but would be glad to know if there&#x27;s another way to do that.
