So I was going about my daily buisness i was watching some videos on YouTube and quickly had to run some errands, leaving my computer as it was. When I came back Firefox had crashed and would not open regrardless of what I did, so i went and restarted my computer and everything worked except HTML5 videos (facebook's fine cause they use their own thing). The one thing that keeps ringing in my head would be to uninstall and reinstall, any advice would be appreciated

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}

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. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

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; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ 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.

so basically look for the instals folder, take out the firefox folder with the user profiles or all of it?

NO. My instructions are only to remove Firefox programs and then reinstall the browser. We do this if there is a chance that something is wrong with the program files.

Leave the profiles alone.

You can open the YouTube test page to check support in Firefox for playing HTML5 media.
