I sync browsers between small old laptop and desktop and use a couple dozen add ons for specific purposes. Each add on when it is updated forces it's own new tab into foreground, disturbing my current work, possibly causing time sensitive entries to be lost. The problem is worse on the smaller system due to delays as add ons update and new tab opens. These get in my way and interfere with my business. Chrome is just as bad with this. Make these add ons better behaved. Show an indicator on the three bar menu icon, which already shows permission changes. I will get to it when free. I want to choose when to view update info, and would be happy with a short update message with links to more info. Also would like to designate time of day or weekday that'''bold text''' Add Ons are allowed to update. Or have just one tab opened in the background where all such update messages appear. Also, as add-ons come in via Sync, do not default to adding to tool bar. That shrinks my URL text box at inopportune times. Again, put it on the Overflow and I'll put it on a toolbar when and where I prefer.
