You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017 and 2019":

• https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
• https://aka.ms/vs/16/release/vc_redist.x64.exe
• https://aka.ms/vs/16/release/vc_redist.x86.exe

You may not need the latter (32-bit version) if you use 64-bit Firefox. You may have to reboot the computer.

I tried following your suggestion Cor-el, but it only lasted a few seconds. As soon as the browser loaded I tried typing and the browser disappeared.

FredMcD, I can't even type about:crashes because the browser doesn't stay open for that long.

I do want to add that whenever I did open Firefox (starting this year for a few months) I got a message stating "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." So I always pressed the "close" button and had to start Firefox. This message showed even in the beginning of me starting up my computer and then throughout the day whenever I opened the browser. I have a lenovo from 2011. I updated my windows as well. I do feel like this laptop is dying so I did buy a new one. Not sure if it's because my laptop's old or if I deleted something that I shouldn't have.

I hope my response doesn't confuse anyone.

If you can't get Firefox to open, you will have to do this the hard way. https://support.mozilla.org/en-US/kb/mozillacrashreporter

I checked the first one because that is when the browser was going haywire. I don't even know what is written in the crash report.

This is a problem with your AhnLab software and should be fixed in a next update.
