The news
Mozilla has begun internal testing of a performance adjustment that would give Firefox the faster application launch behavior Windows 11 already provides to Edge. The work is described as early but shows positive initial measurements.
Context
Edge currently holds an advantage on Windows 11 because it alone receives the operating-system-level improvement for quicker startup. Firefox users on the same platform do not yet see the same effect. The testing inside Mozilla aims to close that gap without requiring changes from Microsoft.
The single source available states that Edge may not remain the sole beneficiary of the Windows 11 faster-app-launch behavior. Mozilla engineers have already begun exercising the matching code path inside Firefox builds, and the first results are reported as promising. No other browser vendors are mentioned in the reporting.
Detail
The feature under evaluation matches the mechanism that Edge uses. Mozilla engineers report that the first runs produced encouraging timing data. No release timeline or version number has been attached to the effort yet. The change would affect only the Windows 11 code path.
Because the underlying Windows 11 optimization is already present in the operating system, the work at Mozilla is limited to adopting the same hook rather than inventing a new technique. The Neowin account gives no further technical description of the change, no benchmark numbers, and no indication of whether the code has reached nightly builds or remains in private branches.
Reactions
No statements from Microsoft or other browser vendors appear in the available information. Mozilla has not published benchmarks or code references beyond the note that testing is underway.
The absence of public comment from either company leaves open the question of whether the optimization was offered to all browser makers or discovered independently. The single published report does not resolve that point.
Why it matters
A browser that starts faster reduces the small but repeated friction users encounter each day they open the application. On Windows 11 this advantage has been limited to one browser; extending it removes an artificial difference between competing products. Software teams that maintain cross-browser tools or test suites would encounter more uniform startup behavior and fewer platform-specific notes. The work also shows that operating-system optimizations can be adopted by third-party applications when the underlying hooks are reachable.
Whether the improvement reaches stable releases will depend on further measurement and integration work inside Mozilla. Users who run both browsers side by side will be able to judge the practical difference once the code ships. For organizations that standardize on a single browser for internal applications, the change could eliminate one minor reason to prefer Edge over Firefox on Windows 11 machines.
Analysis
The narrow scope of the change keeps the impact contained to launch speed rather than broader rendering or memory behavior. If the results hold, Firefox on Windows 11 would lose one measurable disadvantage relative to Edge. The absence of any public dispute over access to the optimization suggests the path is open to other browsers as well. Continued quiet testing is the expected next step before any wider announcement.
Because the source material supplies only the fact of testing and the existence of promising early results, any larger claim about market share or long-term competitiveness would rest on speculation rather than reported evidence. The immediate effect, if the work succeeds, is simply parity on one narrow performance metric that Windows 11 already exposes.
