New tab search engine to Yahoo
I want to change my new tab search engine from Yahoo to Google. I tried changing the settings from the options, didn't work, tried resetting firefox, didn't work. I even went to About: config and tried to find browser.newtab.url it didn't have it, so I'm wondering what I can do to get yahoo removed from my new tab search engine.

Use this for new tab : https://addons.mozilla.org/en-US/firefox/addon/new-tab-override/
As for the stuck Yahoo Engine. If above does not change it just for new tabs then will have to : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

- https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
Reinstall with Current Release Firefox 59.0.1 with a Full Version Installer
If the above does not fix it then some how that is stuck as a preference in your Profile. Create a new profile as a TEST to check if your current profile is causing the problem.

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem. Never work with original files.

Please let us know if this solved your issue or if need further assistance.
Do you have this Yahoo search engine: "Yahoo Search Engine"
This could be an issue caused by AdAware or Web Companion from Lavasoft.
You can look for a file named dsengine.js in these locations.
You should only find channel-prefs.js in the "defaults\pref" location. Any file found here apart from channel-prefs.js is suspicious. You can check the content of the file in a text editor (use open with and do not double-click the file).
C:\Program Files\Mozilla Firefox\defaults\pref\ C:\Program Files (x86)\Mozilla Firefox\defaults\pref\
You can look for a file named dsengine.cfg in the main Firefox program folder.
C:\Program Files\Mozilla Firefox\ C:\Program Files (x86)\Mozilla Firefox\
Delete the dsengine.js and dsengine.cfg files when present.
