No matter what URL I specify or file I open, all I get is a blank screen. This is the version for Monterey. It doesn't seem very useful.

Perhaps it might show a simple txt or html file, perhaps the results of a search, perhaps the content of a website like every other browser. I haven't gotten far enough to download any extensions, so they shouldn't be a problem.
