activate_cdp_mode() is very slow on Windows and opens two Chrome windows with uc=False

[montovaneli]

Hi! I'm experiencing a couple of issues when using activate_cdp_mode() on Windows with SeleniumBase 4.38.2

---

Issue 1: Very slow execution on Windows

When running the script below:

from seleniumbase import SB

if __name__ == "__main__":
    with SB(uc=True, headless=False) as sb:
        sb.activate_cdp_mode("https://example.org/", tzone="Europe/Lisbon")

It takes a long time to execute on Windows, much slower than on Linux or WSL. I'm wondering:

• Is there any known performance issue with activate_cdp_mode() on Windows?

Issue 2: Two Chrome windows opened with uc=False

When I explicitly set uc=False on the above code, I see two Chrome windows open:

One opens with a "data;" URL (blank content).
The second one loads (as slow as the Issue 1) the actual page (https://example.org/).
Is this behavior expected?

Thanks a lot in advance for your help and for maintaining this great project!

1. Windows may be a little slower, but not by too much. The GitHub Actions Nightly Tests here shows a little slowness: https://github.com/seleniumbase/SeleniumBase/actions (Not much I can do about that due to Windows differences.)

2. That's expected. CDP Mode is a subset of UC Mode, so you need to call it from a UC Mode browser. If you're not using UC Mode, it will spin up a new UC Mode browser to use with CDP Mode.

There are, however, two special Pure CDP formats that don't use Selenium at all:

• SeleniumBase/help_docs/syntax_formats.md#sb_sf_24
• SeleniumBase/help_docs/syntax_formats.md#sb_sf_25

Examples of those:

• SeleniumBase/examples/cdp_mode/raw_async.py
• SeleniumBase/examples/cdp_mode/raw_cdp.py
