Firefox stops responding and makes everything lag
This happened when I tried to switch to my pen on CodePen(but it seems that opening the main page does the trick too). Let me mention that when I first used CodePen soon after installing FF it worked great, no lag, nothing. However, I tried opening CodePen again to work on a project and it made the cursor lag, the Skype call started lagging as well because of FF and so forth. I end the process in the Task Manager and everything goes back to normal. I reopen FF, it's still on CodePen and it immediately stops responding. I'm unable to do anything to it other than probably just uninstalling it and being done with FF forever, but I'll give this a try before I absolutely abandon this browser. Processes when FF is not open are using around 16% of my RAM and 20% of my CPU. I open FF and my CPU usage goes up to 60% and the RAM only FF is using is 860 MB. Now, this is not a big concern because I have a lot of RAM to spare, but the problem is that it makes everything else lag badly.
I'm able to somehow get out of that loop, but I'm only using FF for CodePen and if I can't use it for that because someone made an abortion of a browser a thing then I won't use it at all. Any ideas on how to fix the problem? Maybe it's the rendered JS animations that are making it uneasy?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

Here you go. :)
And his started after installing CodePen? Disable it as a test.
CodePen is a website, a HTML/CSS/JS editor with a real time preview. http://codepen.io/
However, just opening the main page makes FF lose it's shit and nothing changed from the moment when I installed FF until now. I just noticed that, for some reason, Ctrl + F isn't opening Find. Let me mention that I have no extensions, haven't synced anything, and haven't changed any settings.
Btw, let me mention that now it works fine in both normal and Safe Mode. I'm not in a Skype call any more which might be the cause. However, Skype, even with the video call going, wasn't using much so it shouldn't have caused FF to lag.
It could have a corrupt file that was overwritten. Keep an eye out.
