  • How the WebRequest API works is:

    1. Network request is made
    2. Sent to the WebExtension
    3. Extension runs arbitrary JavaScript (Slow to very slow)
    4. Repeat for every extension handling requests
    5. Results eventually make it to the WebProcess where it belongs.

    This is slow and will always be. Their change to remove blocking makes steps 2-4 a copy of the data instead of a synchronous call.

    Now an ad can be slower, just by more data or bad JS. But that isn’t Googles concern because they sell those ads.
