Fixes the new_page() hang from #666, and restores the pythonlib/ + settings/ halves of #637-#647 that were dropped when those PRs were consolidated into #666 (that PR only carried patches/ + additions/, so these never actually landed). ## new_page() hangs when window.outer* is spoofed (#666) The outer-size hijack in browser-init.patch pinned the chrome documentElement to the spoofed size. That caps .browserStack, which caps the content viewport, so the content window can never reach the size Juggler asks for in updateViewportSize() -- and awaitViewportDimensions awaits exact equality with no timeout, so it deadlocks rather than erroring. The second new_page() hung forever and took the context with it. The pin was never load-bearing: GetOuterWidth/GetOuterHeight already consult MaskConfig unconditionally (fingerprint-injection.patch), so window.outerWidth is spoofed in C++ regardless of the real chrome window size. Resizing is enough. Measured on the official v152.0.4-beta.26 build (headless): config before after none pass pass inner pass pass outer HANG pass both HANG pass (iw:360 ih:740 ow:360 oh:800 -- exact) This corrects the diagnosis in #666, which blamed the inner+outer combination and the `!(outerWidth || outerHeight)` guard. outer* ALONE is sufficient to hang, and dropping inner* does not help, so that guard is not the culprit. Also fixed driver-side: Playwright's implicit 1280x720 viewport is what asks for the impossible size, so the driver now defaults to no_viewport when the config spoofs any window dimension. That fixes the hang on already-released builds without a rebuild. An explicit viewport=/no_viewport= from the caller wins. ## WebRTC ICE prefs (#538) #666 merged the C++ half of the WebRTC fix but not the prefs, so the shipped build still has no_host=true and none of the proxy_only prefs. proxy_only_if_behind_proxy is the pref that actually stops the real-IP leak: it prevents a UDP STUN request routing around a TCP proxy. no_host=false keeps the stock two-candidate shape, which obfuscate_host_addresses makes leak-free. ## Also restored from the consolidation - fix(proxy): dom.security.https_first rewrote http:// before the launch-arg proxy filter saw it, breaking CONNECT-only proxies (#638). - fix(stealth): speech-voice spoofing + stop leaking host voices (#646). - fix(stealth): clamp inner <= outer <= avail <= screen; BrowserForge can emit impossible geometries that leak as tells (#647).

The core regression these guard: every spoofable OS -- including Linux --

must yield a non-empty list of MaskConfig voice OBJECTS (not raw
|
|
"Name:lang:type" strings), or the C++ MaskConfig::MVoices() silently drops
|
|
them and the host machine's native voices leak through.
