Mozilla Firefox is extremely slow afteer installing some programs

I wanted to install adobe flash player, but accidentally I installed also McAfee security scan plus and true key by Intel security. When I “install” them, only adobe flash appeared. 5 minutes later this program disappeared and was replaced by McAfee. In addition, the true key never appeared. So, I uninstalled McAfee (the only program who was showed in the control panel of these 3 programs). Like that, I don’t have any program of these 3 that I installed. Since I installed these programs, Mozila Firefox became almost unusable. It became extremely slow, Firefox is freezing and very often it shows that Firefox is not responding. Can someone help me to make Firefox fast again and explain me what is happening? Thank you very much for your answers.

hi, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum (or if it's too long through a site like https://pastebin.mozilla.org/ and provide the link here)?

this might give us a clue what is going on. thank you!

Also, check the programs that are on your computer

Windows: Start > Control Panel > Uninstall Programs.

Arrange the list in the order they were installed.

Hi magitop, open up Firefox's built-in Troubleshooting Information page using one of these methods:

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

That's what philipp is referring to as the information that would be helpful to paste here.
