Normal usage of Waterfox, latest test build, seems much like the last few builds. In that through my daily surf routine of news sites, various science related sites, Social Media sites, and various online training sites...memory NEVER got above 450MB (+/- 5MB).
I read up on WebGL in Firefox with an Intel Graphics card. Updated my drivers, went into "about:options", made sure that "webgl.disabled" was set to false and that "Hardware Acceleration" was active in Options->Advanced section of Firefox. I couldn't tell you one way or the other if it was the driver or that I wasn't running hardware acceleration last test, but in doing the exact same things...my memory never got above 900MB...running the same activities as earlier in the same browser in different tabs. I even went to the extent of running all the aforementioned sites in separate windows and still my memory usage never went above 900MB. Small fluctuations in one way or the other, that were negligible at best. I also never crashed on the site, David Walsh WebGL Demos
, which crashed WF last test I did. So between this build and two builds back memory usage decreased by 300MB, since before when running these same tests I had usage of 1.2GB and crashed. Again, I don't use WebGL and usually have it disabled with hardware acceleration turned off. Videos on Youtube tend to run better for me in full screen when acceleration is off and I spend a lot of time with tutorials and the like that use video.
I tried to learn a bit more about WebGL, but got bored with it as it isn't something I am entirely interested in to begin with. However, it does seem that the video drivers are the most important factor here and browser settings. Albeit, there are those video cards that either aren't supported or just don't work in some browsers. These are things that I read repeatedly from a simple Google search of "WebGL issues". I encourage anyone who is interested in WebGL to read a bit on the subject. Especially if it is a deal breaker on the browser you intend to use.
As for me...well I just disabled WebGL in firefox and turned hardware acceleration back off, as it suits my needs fine. Good luck to the rest of you and I hope this was somewhat helpful in testing this latest version of WF, thanks to Alex's efforts of course.
