Ever since last week up to 2 weeks ago my browser will just freeze for no reason at all and even freezes my computer to where I have to shut it down! Help!

Question

Ever since last week up to 2 weeks ago my Firefox Browser (26.0 Version) will just stop working and say (Not Responding) like ever 5-10 minutes, even reset the browser and even put it in Safe Mode still the same thing happened and it will freeze my computer to where I have to shut it down. Also I have run my Microsoft Security Essentials anti-virus, malwarebytes, and superantispyware software (not at the same time obviously) still nothing and run C Cleaner, and then if I am watching a movie, listening to music or playing a game in the browser or Spotify it will say plug-in not working and asks me to shut it down, same thing will long scripts and I don't understand this I am at my wits end what do I do? Because this is becoming ridiculous real quick! Thanks in advance for anyone who can help me answer this question!

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
Thank you.

<b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>
