Add-on context menus display only when launching them through overflow menu, it doesn't work when I put the icon next to the navbar.

I have a smaller DPI non-retina MBP2012 and I always set the default page size to 80% in Chrome. I used two extensions for the same functionality in Firefox (Fixed Zoom and a second one that worked a bit better) but I always had issues with the sites being bigger than the viewport and having to scroll around them to see the content. Images were the biggest victim to this behaviour.

You are right - there are issues in Chrome, but I don't feel them as much in my day to day life and it counts for me.
