If you're using a computer from any time in the past 20 years or so it's probably capable of multitasking so you can open another browser to pay your bills in the meantime.
I'll give myself as an example, between writing that first comment and replying to you, I downloaded and built ladybird on MacOS - it took 25 minutes, most of which was me fixing build dependencies - and here I am replying to you from an alternative browser. Text navigation is a little weird and text boxes are weird, but so far it works.
Of course, if building in the background is more effort than you're willing/able to expend, then continue using Chrome or Firefox until others finish the alternative, and then decide if the time required to download, install and get used to a packaged browser is also going to be a hindrance to you paying your bills.
