If I were to use IE6 in the way that I do Firefox, I would have 547 windows on my taskbar. No thanks.
Heh. It's 9:30 in the morning and I already have 13 browser tabs open across two browsers (and earlier thing morning I had four .PDFs and two Word documents open as well). Part of it is that one of the websites I use every day throughout the day opens things in new tabs by default. Most of the time I might find that annoying, but for that site it's actually useful because keeping its main page open in one tab makes access to other information a lot easier.
It's 8:40 am here.
Firefox — 1 window, 1 tab
Chrome — 3 windows, 7 tabs
Internet Explorer — 1 window, 2 tabs
One of the sites I use in Internet Explorer opens links in Edge.
The bulk of my daily work is auditing job pay: (1) how much our field techs are billing us for the work they do, and (2) how much the MSOs are paying our company for those same jobs. When I'm in the middle of auditing a given region, my Firefox browser might have 15 tabs open at one time. This is because each work order in our WMS has a unique URL, and I find it convenient to open a dozen or so at a time and then work through that chunk before moving on.
