Describe the bug

Hi there,

I tried to use Firefox browser for loading page and getting whole HTML code. Problem is... this is slow. Incredibly slow.

These two lines take in my test from 17 to 25 seconds, measured with Stopwatch.
On Webkit it's between 4 and 6 seconds, depends on using or not VPN.

How is this possible?

Version of browsers:

• Firefox: 86.0b10
• Webkit: 14.1

I didn't try downgrade of Playwright. I'm fine with using Webkit for now, but wanted to report that something is wrong with Firefox here.

@hahyes is this a regression? Could you please try an older version, e.g. 0.180.0?

I'm fine with using Webkit for now, but wanted to report that something is wrong with Firefox here.

Thank you for the heads up! ❤️
