The last time I ever used two browsers was back in the mid-1990s, with Netscape and Internet Explorer. By the late '90s, I abandoned Netscape and solely used IE up to this day, because after all, it seems EVERYBODY is using IE because its already there in Windows. I didn't feel like installing a competing browser such as Chrome or Firefox or Opera because it wasn't necessary for my needs and having an extra web browser is more a nuisance. I have tried these three browsers on other computers and I never felt comfortable with them... and the sites I have them load up seems to not come up correctly as IE does. Thats why I prefer not to use them. But I understand times have changed and a lot of users are surfing with FireFox or Opera. I have seen and used public computers that has FireFox.
I noticed while websurfing the last year or two that some sites I encountered can be best seen or only can be used by FireFox or Chrome, not IE. I have been a one browser user for over 10 years. Is it time for me to seriously reconsider and install a second web browser on my desktop computer?
I understand there is not a true right answer here as every computer user's needs are different.
