Yesterday, I had some sort of problem with my laptop, so I restarted it. After logging in and such, I wasn't able to access Firefox again, I clicked it multiple times (giving it 5-10 minutes to load) but nothing loaded. I had to use Google Chrome to ask for help and it it told me to un-install it. I did so, but when I tried to download Mozilla Firefox, nothing happens, I click "run" on the pop-up after downloading the set-up and nothing comes up. It doesn't install at all, no error appears either. I need help asap.
