Since my earlier post regarding setting Firefox up to utilize CPU affinity in Windows, things have been manageable, but lately a familiar flavor of failure seems to have crept back into this latest release.
If I leave Firefox open and running overnight with my usual group of a dozen or so tabs open, as soon as I resume activity in the morning, I notice in Task Manager that Firefox has one of my system's CPU cores at 100% usage, and has well over 1.7 GB of system memory in use, far more than what typically ranges from 400 to 700 MB on an average day.
Any given morning, thanks to Firefox. |
More often than not, once I clear this CPU usage spike by ending the firefox.exe process, when I reopen Firefox I'm greeted with tabs notifying me of add-on updates that have been applied.
This same issue seemed to be absent as of, say, version 10, but appears to have recently reemerged, at least in my experience on several different PCs running Windows 7.
A common thread among established users on the Firefox support forum points to the various add-ons users have installed. Clearly, many of them say, this is the culprit, and the often the user is advised to open Firefox sans add-ons and attempt to reproduce the problem by enabling add-ons one by one and testing after each to determine which might be the culprit.
I have no desire to invest the time and effort in something that I think developers and analysts at Mozilla should be hammering out themselves. It seems that if you release a platform on which users will develop add-ons, there should be safeguards in place to prevent poor coding from disrupting the integrity of the browser's functionality.
That being said, if you have a 64-bit system, consider trying out Waterfox, a Firefox build which emphasizes performance and speed, and mitigates a lot of whatever lurks in Firefox's codebase that might be causing this excessive memory usage and lag.
Perhaps it's some insidious conspiracy to make it so that when your computer is otherwise asleep at night, Firefox will rear its head and ramp up CPU usage and therefore power consumption, making an impact, however small, on world oil prices, driving up costs and compelling people to bite the bullet and get off the grid with their own solar, wind, nuclear, or other alternative power source.
I've had crazier ideas!
