Playwright with Firefox: New Windows vs Tabs and Chromium-specific Features

Hey Playwright community! I've been using Firefox with Playwright because it uses less CPU, but I've run into a couple of issues I'd love some help with:

1. New Windows Instead of Tabs
   I'm running Firefox in headless: false mode to check how things look, and I've noticed it opens new windows for each URL instead of opening new tabs. Is there a way to configure this behavior? I'd prefer to have new tabs open instead of separate windows.

1. Chromium-specific Features in Firefox
   I'm getting this warning when using Firefox:
   
   Plain Text

   Copy

   WARN Playwright Utils: blockRequests() helper is incompatible with non-Chromium browsers.

   
   Are there any polyfills or workarounds for the playwrightUtils features that are Chromium-specific? I'd like to use blockRequests() or similar functionality with Firefox if possible.

Any insights or suggestions would be greatly appreciated! Thanks in advance for your help.
