Brave Browser, which recently reached more than 100 million users worldwide, has rolled out a major overhaul of its built-in adblocking engine, cutting memory consumption by 75 percent and delivering a measurable performance boost across desktop and mobile platforms. The changes are live starting with Brave v1.85, with further optimizations scheduled for v1.86.
According to the Brave privacy and security team, the reworked adblock engine now saves roughly 45 MB of memory by default on all supported platforms, including Android, iOS, and desktop systems. The savings increase further for users who enable additional filter lists.
I admit, it was a poorly worded, poorly informed question. It should have said something more like, “I am surprised this browser is open source, despite everything”
