Release Notes (v1.5.0)
What's New & What's Changed:

Stealth Ad-Blocking Rewrite: Completely re-engineered the ad-blocking mechanism to bypass YouTube's recent anti-adblock updates ("video player will be turned off after 3 videos").
Pre-Load Interception: Instead of fast-forwarding or skipping ads after they load (which triggers YouTube's server-side telemetry), the extension now intercepts player configurations and strips ad-related payloads before the video player initializes. The player behaves exactly like a clean, ad-free stream.
Invisible CSS Rules: Updated styling injections from standard hiding (display: none) to a stealth layout collapse (visibility: hidden + height collapse). This prevents YouTube from detecting hidden ad slots while keeping banners invisible to the user.
Improved Performance: Replaced the high-overhead MutationObserver on the document body with a lightweight periodic check for anti-adblock warning popups, drastically reducing CPU/memory footprint and fixing video page slowdowns.
(Note: If you were already flagged with the "3 videos" warning, you may need to clear your YouTube cookies once to reset your playback session state after updating the extension).

Previously, playing YouTube audio in the background on Firefox/Chrome Android required users to manually toggle 'Desktop Mode' in the browser menu. In this update, the Background Play feature has been completely rewritten using page-world JS execution (wrappedJSObject on Firefox / main-world scripting on Chrome) and capture-phase visibility event interceptors. The extension now successfully spoof-blocks all visibility API state changes on mobile devices, allowing seamless background audio playback on both m.youtube.com (mobile view) and youtube.com (desktop view) without any menu toggles.

Fixed Shorts Blocker: Resolved a bug where an invalid CSS pseudo-class selector was causing Firefox to discard the entire style sheet rule block, which silently disabled homepage Shorts hiding.
Added Support for Modern YouTube Layouts: Added targeting rules for new YouTube elements, including ytd-shorts-lockup-view-model-renderer and individual in-grid Shorts.
Improved Blocker Resilience: Split CSS rule blocks into isolated groups. If YouTube changes or introduces a class name in the future, the other blocking rules will continue working independently.
Extended Channel Page & Search Results Rules: Improved cleanup of Shorts grids on specific channel tabs and search result pages.
