Hard to say. It's actually already in stable but currently limited to a very specific set of OS/hardware combinations and they're working on gradually adding more. FF67 enabled it in stable for desktop NVIDIA hardware on Windows. AMD and Intel GPUs on Windows and Linux are currently enabled in the nightly channel, presumably MacOS is next on the list once those are stable. Webrender is mostly done and at the stage where there are mostly just lots of little bugs left to fix so it's naturally kind of hard to estimate how long things will take.
Yeah, I went and installed Firefox on my home machine after this landed in 67 since I have the right hardware and...
It's SO much fucking better.
Lots of folks on here claiming that Firefox has been just as good as chrome in terms of performance for years, and frankly that's an utter load of BS.
On top tier hardware (and honestly - most hardware in general) chrome was always blindingly fast, and Firefox just wasn't. It was perceptibly slower at just about everything.
It was just annoying enough that I'd always switch back to chrome for personal use.
Not anymore. This last week is the first time I can remember that I honestly can't tell the difference in speed. If anything, Firefox may actually be legitimately beating chrome in terms of speed.
It's been a pleasant breath of fresh air. Google may lose me as a chrome user (personal use at least), which is something I just couldn't have imagined a year ago.
