Firefox uses 100,000 K - 200,000 K memory even in safe mode; hangs and freezes periodically

Question

In the past week or so I've been experiencing regular freezing and hanging, but only when Firefox is open. The freezing and hanging can affect other programs, but it always starts with Firefox. It can be either a) the browser stops responding, dims white, and the spinning circle appears, b) browser stops responding as does the task bar, can't click on any other open windows and sometimes the task bar dims as well, or c) the screen freezes entirely, with mouse movement not shown (although the mouse does move--it appears to freeze, but if I move it and wait, it'll be wherever I moved it) and if I was loading a page, the loading circle in the tab stops moving as well; it's as if a screenshot has been taken and replaced the screen.
I'm thinking this has to do with memory usage; Firefox uses 200,000 K memory normally, and starting in safe mode only drops it by 20,000 K - 30,000 K.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
'''For Firefox versions previous to 29.0:'''
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox"[[Image:Button reset]] button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
'''For Firefox 29.0 and above:'''
#Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''.
Now, a new tab containing your troubleshooting information should open.
#At the top right corner of the page, you should see a button that says "Reset Firefox"[[Image:Button reset]]. Click on it.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
