Firefox 141 Beta Lowering RAM Use On Linux But Still Benchmarking Behind Chrome
With the Firefox 141 Beta testing I didn't see any performance improvement compared to Firefox 140 on Linux...
But there was a clear improvement in system memory use. Around 230MB less RAM was consumed while running the Speedometer 3.1 benchmark. While ~230MB may not seem like a lot, this was just a simple single-tab test case and likely to be compounded with more common use-cases of multiple tabs across the span of hours of use.
With the Jetstream 2 benchmark running in Firefox 141 Beta there was also around 300MB less RAM being consumed on this Ubuntu Linux desktop.
