Why is Firefox so damn slow with 16G DDR3 memory on a Sandy Bridge CPU?

Posted

As I am writing this message on this forum I have 63 open tabs in Firefox version 10.0. None of them are streaming video or anything like that. They are static pages.

I am running Windows 7 64-bit Ultimate on a Sandybridge Core i3-2105 CPU. I have 16GB of DDR3 1600 memory. Why does a simplistic browser run slower than a 3d video game? I am using the integrated graphics on the Sandybridge CPU(Intel HD3000 graphics). But I don't think the graphics are what causes the slow performance. I don't understand why I can't have a 100+ tabs open in Firefox and get instantaneous tab switching with a system as powerful as I have. Tell me what I must do to make this slowness go away, please, somebody. Thank You.

I would not expect Firefox to be slow on such a system. I am not having problems and have much less powerful systems than yours. I would expect it will turn out to be related to the Firefox extensions that you are using so try in Troubleshoot Firefox issues using Safe Mode.

Developers are looking into speeding up Firefox, but simply switching between tabs should not be a problem.

Glad to hear it has improved.

One of the biggest advantages of Firefox is that is is almost infinitely customisable.
One of the biggest disadvantages of Firefox is that is is almost infinitely customisable.

When it comes to troubleshooting any problems, the software extensions may introduce memory leaks or unexpected interactions and so it is best to start again in the basic safe mode. It simplifies the situation and allows comparisons and tests to run under known and comparable circumstances, that is an inconvenient necessity. I hope you manage to narrow down the problem and ultimately find what is causing it.
