I've been noticing it for the last couple of months, only happens on these forums, memory usage will climb to the several gigabyte range before falling again back to normal
If Firefox had that type of memory usage (6 gbytes), My computer would probably start freezing or crashing whenever I used Firefox.
When I am running Firefox, it uses around 550- 650 mbytes of memory whereas Google Chrome uses around 350 - 450 mbytes of memory. Firefox does seem to be a Memory hog for some reason. But I will keep an eye on the Memory usage since you brought to the Forum's attention.
Damn, that link is correct. I went to Weather.com on latest Firefox with one Tab open. Task Manager showing around 28% CPU Usages but over 1.6 gigabyte of RAM Memory being used.
I did it a second time with same version as before Firefox 59.02. When I went to Weather.com the CPU fluctuated between .04% to 2.5% with around 920 gbytes of Memory being used. As soon as I clicked on Okay to use my location, the Memory shot up to over 1.2 gbytes and CPU fluctuated between 1.5% to 5% usage.
Still no issue, ram dont go above 700mb and cpu go to 5% for a second and go back to 0 - 1%, maybe is my ASC11 that is handling the things since i use to optimize everything even internal features from MS, to not spy you.
I will keep an eye out for this and keep Firefox open and see. Since going to an SSD I rarely leave my browser open so I close it as soon as I am done. I have these pages set to load when relaunched. I will check it out though.
Why don't you leave your browser open with an SSD? Modern drives have an endurance rating of not less than 50TBW unless you get a really junk drive, even the 250gb Samsung 850 Evo has a 75TBW endurance.
Honestly no good reason other than it relaunches so darn fast I just close it. I have an NVME drive with 3D nand so re-writes were never even a consideration. Honestly it's mostly just to clear the browser cache and history, wink wink, nudge nudge, say no more....
