Initializing CDP Mode from a non-blank page may cause the browser to crash #3862
Description
Initializing CDP Mode from a non-blank page may cause the browser to crash
Most people probably didn't see this happen because the default start page when the browser is launched is usually chrome://new-tab-page/ (for UC Mode starts before initializing CDP Mode). Other safe URLs weredata:, and about:blank, which didn't have issues either.
So this is probably a rare issue because most people activate CDP Mode right after launching the browser.
The issue here was caused by some old workarounds used to keep the browser clean before being stealthy. Those including opening an extra, fresh driver for UC Mode, as well as opening a fresh tab while closing the previous one if the browser had already navigated to sites within UC Mode before activating CDP Mode.
The incoming fix for this should prevent the crash, but if the user was already detected as a bot by a website in UC Mode before activating CDP Mode, then the website could remember that you're a bot, either by IP address, or by cookies saved, and therefore CDP Mode might not save you. It's best to activate CDP Mode from a fresh UC Mode browser to maximize stealth and to prevent detection as a bot.
