Firefox still constantly crashes

I posted this question before, and it got escalated, but there wasn't a resolution or fix suggested. I am hoping with more crash reports I can get some help finding a solution! Firefox is now crashing routinely - as in, many times each day. I am at my wits end! It's not profile-related as I sync my browser profiles and have no issues on my other computer. I did a clean install, and the crash frequently slowed for a while, but now I'm back to tearing my hair out. Please help!

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.

Download Firefox For All languages And Systems {web link}

Firefox ESR; Extended Support Release {web link}

Beta, Developer, Nightly versions

Install Older Version Of Firefox {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder.

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux;

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

Well, that was interesting! Downloaded the new install file, deleted the application, restarted, and chaos ensued. Wouldn't restart normally, wouldn't restart in safe mode, wouldn't restart in safe mode after a disk repair, so ultimately had to reinstall the operating system. So this is as clean as an re-install gets. Hoping that it solves the problem!
