Firefox 57.0.4 takes CPU utilization to 100%

I have a PC running Windows 7 32-bit with Firefox installed. When I open Firefox it instantly takes the CPU utilization to 100%. I have to kill the application to get the CPU utilization to drop back to normal levels. I have uninstalled and reinstalled Firefox but, I am still having the same issue. I looked through the event logs but, it is not generating an error when it pegs the CPU. Is there a known problem with Firefox 57.0.4?

Firefox has become worse about both CPU usage and memory usage over the last four years.  It used to run in a relatively reasonable 128M or so, but on my 32-bit system it takes half a gigabyte and half the available CPUs when it is not doing anything.

(Amusing side note:  Bringing up the process monitor and watching a minimized Firefox showing about:blank exiting the system, it goes from 140 MB to 395 MB.  As it exits!)

So while I haven't seen this personally (I reverted to Firefox 38.8 and disabled updates because later versions behave so badly), I certainly would npt say it's surprising.  Reportedly the Firefox development team is working on a "slim" replacement for Firefox that is not ... quite such ... a hog.

Suggestion:  Remove Firefox and drop back to, say, version 52 and see if the problem improves.

Can you try other browsers and see if they do the same thing?  If they do it is a malware infection.

When you uninstalled Firefox did you also delete the existing profile data? From what I've found, people with similar issues found that deleting and creating a new profile or at least deleting the preferences file (keeps track of settings like zoom, updates, where to save downloads, etc...) for their profile resolved the issue.

This Mozilla support doc provides instructions for clearing profile preferences:

Most likely it was a malware infection or resource hungry version of the browser. The solution with the most upvotes chosen as best. Split even for the rest of the experts.
