I remember one time my dad wanted me to look at his pc because the "browser was getting smaller". Opened IE and he somehow installed the same toolbar three times, they were stacked on top of each other.
Well, more useful than crazy, and honestly most of them are fairly minimalistic in their footprint. 9 tiny buttons next to the url bar, with 9 more hidden extensions.
I do have to uninstall a few of them. I don't go to reddit anymore so can ditch the enhancement suite, and the opera gestures never actually worked...
Oh god I knew a guy who's internet explorer was all toolbars like this. Literally 20% of his screen was usable, tops. I offered to help him with it and he said he had it the way he liked it. This wasn't even the early days of technology or anything, it was 2014 lol
