Chrome v117 Headless is Detected in UC Mode

[jdholtz]

This relates to ultrafunkamsterdam/undetected-chromedriver#1559. I'm attempting to log in to https://mobile.southwest.com in headless mode. While it works in Chrome 116 flawlessly, it isn't working in Chrome 117 (it works in headed mode though). I'm not sure what changed in Chrome 117, but something must be very different because many people are reporting this same issue on UC.

Something has changed. If my calculations are correct, I'll have a new release with the fix ready in less than 3 hours.

Awesome! Let me know if you need me to test at all

This was resolved in 4.18.6 - https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.18.6

Here are some existing examples that use --uc mode:

• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/verify_undetected.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/uc_cdp_events.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/raw_uc_mode.py

Let me know if any of those have issues after upgrading to seleniumbase 4.18.6.

4.18.6 works. Thank you very much for the quick fix!

Looking at the code, was the user agent giving headless mode away? Was the fix just to remove the headless part from the user agent?

[mdmintz]

That was it. Change HeadlessChrome to Chrome in the user-agent, and things work.

For the record, the "in less than 3 hours" time estimate was accurate:
