On my Lenovo laptop, the left shift key doesn't work within Firefox.

Both shift keys work in other browsers, other programs, etc. The right shift key works within Firefox. When I try to use the left shift key together with another key, nothing happens. For example, a capital H just won't appear and if I type "Hi" it appears as just "i". When I plug in an external keyboard, both the right and left shift keys DO work

What I've tried so far: - Uninstalled and reinstalled FF - Tried FF in safe mode - Uninstalled and reinstalled the keyboard from Device Manager in Windows - Restarted laptop

None of this works! Would appreciate suggestions.

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) 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.
