As of recent Chromium updates (which Opera implements), the explicit #enable-parallel-downloading flag has undergone changes. In many stable releases, this feature has been , meaning the flag may no longer appear in the search results because it is no longer an "experiment"—it is now the standard behavior.
For users seeking "verified" confirmation, the absence of the flag in the experimental menu often serves as proof of its stability and graduation to standard feature status. Empirical testing via network inspection remains the definitive method for verifying active parallelization. As web protocols evolve (such as the adoption of HTTP/3 and QUIC), the necessity for application-level parallel downloading may diminish, but for the current HTTP/1.1 and HTTP/2 landscape, it remains a critical performance enhancement. Click the Relaunch button that appears at the
