How do I add a search engine when this happens?
When I open a new tab (or an existing one) and try to search using any of the 3 search boxes, nothing happens. When I enter a website starting with www., nothing happens. I installed AVG software recently. This is a recent problem. I have no way to search in Firefox. I don't seem to have any search engines installed any more, and standard directions on installing a search engine don't work.
In settings when I click on the magnifying glass, often nothing happens. Clicking any other icon in settings, like privacy, etc., works fine.
The green automatically add button below gives me an error message.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button# or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button# or Tools -> Add-ons -> Appearance
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

Let’s do a full clean re-install; http://www.mozilla.org/en-US/firefox/all/ Download Firefox For All languages And Systems
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. 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
===============
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.
