Try to disable hardware acceleration in Firefox.

Okay, I have just disabled hardware acceleration for Firefox, and I would like to ask if you want me to do the same for the Flash Player. I also want if this will have a major impact on Firefox's speed and performance, since I have a relatively slow Internet (usually 60-70 KB per second).

That said, here are the IDS for the five most recent crash reports I've sent:

bp-81778395-714e-499a-84f0-df3672130829
bp-5dbcfe82-6506-4449-a75b-bb87b2130826
bp-915d2c4a-74d5-4bf4-8491-81aef2130824
bp-57145a72-ec65-4a30-8dfd-2f3892130822
bp-28ee57df-9600-4bd4-a875-e60312130812

Feel free to look up these IDs and make suggestions accordingly. Thank you, everyone, for your help.

If you have a slow internet connection then you most likely won't notice any difference in performance.

Note that the crash report seem to be from August (Date Processed: 2013-08-29), so they may not be from the last few days.

You can check for problems with current Flash plugin versions and try these:

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

Quick question: where would I find the Real Player plugin? I checked in the add-ons section and did not find it. I couldn't find it on my computer anywhere, either.

Also, I noticed that while I was watching a video with YouTube's HTML5 player, the CPU usage for Firefox went up to 20-30%. Is this normal?

You can skip that step if you do not have the RealPlayer plugin.
You can do only the steps that apply to your installation .

I have tried all of the suggestions, but I am still experiencing hang-ups in random situations, even when I am trying to load up a Google search. I've noticed that Firefox's CPU usage randomly spikes from 0% to 20-30%, even when I am not using anything with Flash. I really need advice right now, because about 3 weeks ago, I was able to have up to 3 idle YouTube videos and 15-20 tabs open with no performance issues. I will take any suggestions you can give me, since I absolutely need by computer and Internet to be running the best they can for my college work.

Have you tried windows safe mode, maybe another program like a Antivirus or driver is interfering.

I am fairly certain that my drivers or my anti-virus software are not causing Firefox to hang. All of my important drivers are up to date, and I have had no problems in the past where my anti-virus software caused my browser or my computer to lag. What concerns me is that I have not had any occurrences of these problems until roughly 3 weeks ago, and I am not certain what is causing them to happen.

So does it work properly in safe mode?

I have not yet tried running my computer in safe mode, but I will make sure to do so the next chance I get.

So, here's an update: I created a new places.sqlite file and did an uninstall and new installation of Firefox. That said, I am still experiencing problems with Firefox's CPU usage. With only one YouTube video playing, the overall CPU usage of my computer randomly shoots up from 0-1% to 40-50%. Bear in mind that this happens with only two tabs open. If there are any suggestions to help with this, I would gladly take whatever I can get.
