Firefox has been on my computer for almost two years. I always open all my e-mail accounts with Firefox and it is my regular browser for do internet searches as well. Firefox icon is on my taskbar. To open my e-mail accounts, I right click on the icon, which, in turn brings up menu with all my e-mail account. I then click on whichever account to open and it opens.

This evening I could not even open Mozilla Firefox icon. I right click on it and it wants to open: I get the hourglass, very briefly, but then it disappears and nothing opens.

What's your computer system and Firefox version?

Let’s do a full clean re-install; 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)

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.

Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done.


If there is a problem, start your Computer in safe mode and try again.
