I develop mostly in PHP, so it makes sense that I have the Open PHP/HTML/JS In Browser installed in my vscode-worspace. One thing I haven’t been able to get it to do however is open a browser from the Windows when using an SSH or WSL connection. However, you can install Midori on WSL, and it will open as a graphical environment. Just map the custom browser to /usr/bin/midori after installation.

sudo apt install midori
