Firefox-source-patched stealth as a sibling engine (FYI)

[feder-cr]

hey, sharing as fyi since botasaurus and feder-cr/invisible_playwright are working on the same problem (stealth automation that survives modern anti-bot) but from different engine sides.

botasaurus's approach: undetected Chromium driver path. open pain visible in #282 #276 (Cloudflare bypass on Linux + general) and the closed #290 ("headless are now detected"). all of those come from the Chromium-side surface that anti-bots have learned to fingerprint.

invisible_playwright's approach: Playwright Python wrapper around a patched Firefox 150 binary (feder-cr/invisible_firefox, MPL-2.0, same license as Firefox upstream). fingerprint patches at the C++ source code level so there are no JS shims for anti-bots to detect. covers the same Cloudflare turnstile and similar cases on the Firefox side.

not proposing any code change to botasaurus. just leaving the pointer in case it's useful as a reference, or for users who land here looking for a Firefox-side fallback when the Chromium path gets caught on a specific target.

@Chetan11-dev worth exploring a Firefox-source-patched stealth engine alongside botasaurus? opt-in, no change to defaults. happy to close otherwise.
