I wanted to reset my computer so I saved my profile, reset my machine and then installed Firefox. I copied my 'old' profile to my new profile. Initially, this worked and my browser (with bookmarks, settings, etc) was working as it was before the reset. I restarted my machine and now I get this error when I try to open Firefox:
<toolbarbutton --------------^="" <="" class="close-icon" id="UITourTooltipClose" p=""></toolbarbutton>
In addition, a folder was automatically created on my Desktop called 'Old Firefox Data'.
What should I do next? I still have my 'old' profile info on my USB. Should I uninstall Firefox and start over?
Thanks in advance, LB
Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.Read this answer in context 👍 0

First, let's do this: 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.
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.
