WebRequest API vs. DeclarativeNetRequest API:
MV2:
Uses the webRequest API, allowing extensions like uBlock Origin to dynamically intercept and block network requests. This enables fine-grained control, making ad blockers highly effective (80–90% ad-blocking efficiency).
MV3:
Replaces webRequest with declarativeNetRequest (DNR), which relies on predefined rules (up to 30,000 built-in, 330,000 shared if only one blocker is installed). This limits dynamic filtering, reducing effectiveness (10–20% for some blockers like uBlock Origin).
Filter List Limitations:
MV2:
No strict limit on filter lists, allowing extensive and customizable ad-blocking rules.
MV3:
Caps filter lists at 100 pre-installed (50 active at once) and restricts updates, impacting real-time ad circumvention. This can lead to more ads slipping through, especially on platforms like YouTube.
Background Scripts:
MV2:
Uses persistent background pages, enabling complex logic for ad blocking.
MV3:
Replaces these with service workers, reducing memory use but limiting functionality for real-time request processing.
