Why do you developers keep insisting breathlessly that 64-bit builds are memory hogs? I'm a power user who has 3 windows and 1,565 tabs open. I have a 4 GB laptop and a 16 GB desktop replaced a 6 GB desktop. I like to think that I use Firefox close to its breaking point. On any given day, Firefox takes between 2.4 GB and 3.1 GB no matter whether it was the 32-bit build or is the 64-bit build. Only one time while I was using the 64-bit build did I notice it climb on its own all the way up to 5.9 GB, but then the memory was released and it settled down to 3.l GB again and, I repeat, that was only ONE TIME. Microsoft has a 64-bit version of Edge that I use. Also, I downloaded the 64-bit beta version of Google Chrome and use it with little problem compared to its 32-bit version. Under what I consider normal circumstances, I just don't see 64-bit versions eating memory like Mozilla developers keep insisting they do. Now to be fair, I understand not wanting to put the 64-bit version of Firefox on low memory systems. I left the 32-bit version on my 4 GB laptop. I would personally say that x64 OS's with 6GB or more memory should be able to be upgraded to the 64-bit version of Firefox. After NPAPI support goes away, there really should be no excuse to leave such systems on the 32-bit version as the 32-bit version doesn't take advantage of all of the 64-bit OS features and 64-bit processor's features. And as I have said previously, the 64-bit version is way more stable than the 32-bit version. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
