So you've chosen Wac Browser, good choice. To get started, note that not too many of your favorite websites will support it, Wac Browser was made as a Windows Form application in Visual Studio Code and is not built on any other software.

There is an existing workaround for YouTube, you can switch the "v" and "?" in the video url, you'll get redirected to a channel, ignore that, then you can search for the video you were trying to watch. Beyond this I don't know how to get around browser support restrictions.
