The main reason is that i have 2 different sets of bookmarks. I know there is probably a smarter way to do it but opening a different browser is simple enough, and i got used to it. Also I’m lazy to switch between college and personal gmail account, easier to just open the browser for the specific purpose. And my tabs will remain open on the college browser so i can continue the work.

I don’t really use bookmarks on my phone, so there i just have one browser.
