I've always kind of been a "browser junkie".
I'll have ONE default browser that has to work on ALL of my 24 bookmarked finance, news, and entertainment websites.
But tend to always have a small handful of browsers "on the side".
My longest-running default was GreenBrowser coupled with Proxomitron - 17yr run at least, could be more (going by my archived installation disks).
During that run, my secondary tended to be Sleipnir and I kept Maxthon and Opera around but didn't really use them that often.
It became a daily "tweak" to keep Proxomitron happy with all of my bookmarks (back then a much longer list of daily forums and whatnot that I've lost track of).
A couple finance sites would no longer work so that lead me to "official" Pale Moon which I used for three, maybe four years, right in through there.
I discovered Mypal to load FASTER and work on everything I needed it to work on and used it for two or three years.
NM28 became my default for a few months or so but then opted for NM27 and it was my default for two or three years.
I grew tiresome of updating WEEKLY and also found that NEWER versions of NM28 and NM27 were actually performing SLOWER than older versions.
So I dropped back down to Mypay 27.9.4 for only about a year until having issues with the same couple of finance sites that lead me to "official" Pale Moon in the first place.
I then ran 360Chrome v13 for several months and have been on 360Chrome v12 for the last couple of months.
I use 360Chrome v11 in most of my VirtualBox VMs.
