Yahoo one of 8 search engines that come with Firefox in the US. It is quite easy to set a different search engine as your default and you can un-check Yahoo so it isn't even available. https://support.mozilla.org/en-US/kb/change-your-default-search-settings-firefox

Mozilla wanted to get more away from what Google is as Yahoo has been the default search engine in en-US Firefox since Fx 34.0 while other locales changed to other defaults.

You still have the Google search engine you can change back to.

Maybe the problem is malware taking charge? I'm not sure you voluntarily chose to install the "Many Results Hub" extension, which is considered intrusive adware by most scanners.

Here's my suggested procedure for tracking down and cleaning up bad add-ons, hijackers, and ad injectors. I know it seems long, but it's not that bad.

(1) Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.

(2) Open Firefox's Add-ons page using either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons
• in the Windows "Run" dialog, type or paste
  firefox.exe "about:addons"

In the left column, click Plugins. Set nonessential and unrecognized plugins to "Never Activate".

In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions. Bear in mind that none of these came with Firefox, they are all optional.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Any improvement?

(3) You can search for remaining issues with the scanning/cleaning tools listed in our support article: Troubleshoot Firefox issues caused by malware. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.

Hopefully this will let you regain control of your preferred settings.

BS you must know that firefox signed a deal with yahoo. you can't change your search engine - it defaults BACK to yahoo

Hi dinky11, you can set and keep any default you like -- if Firefox is working normally. Obviously there is something deeply wrong with your installation.

When does your default search engine change:

• When you close Firefox and start it up again?
• When you shut down Windows and start it up again?
• Randomly during your session?
• You can never change it successfully?

Just because you are having a issue with search enging changing back to Yahoo for en-US Firefox does not mean it is a typical Firefox 42.0 problem.

seems to make no difference ---- if i change it and stay in firefox - next time I go to home page, it is changes back to yahoo if i change it and leave firefox --- it is back to yahoo when I come back on

also have tried all the tricks to change my default back to google to NO avail it ALWAYS defaults BACK to yahoo even though I have deleted any reference to yahoo in firefox

it all started with the new upgrade and I have been informed that firefox is getting rid of google and going with yahoo as a partner ---- its all over the net

again I say shame on you firefox !!!!!!!

When you say you go to the home page, do you mean without closing the current tab you click the Home button to load your home page, then when you search it uses Yahoo?

That sounds like it's either an extension or a program folder hack. I already gave you the details steps for rooting out an unwanted extension.

To clear a program folder hack:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean (no inconsistent, corrupted, or alien code files). As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(A) Download a fresh installer for Firefox 42.0 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)

(B) Exit out of Firefox (if applicable).

(C) Rename just the current program folder, either:

(64-bit Windows folder names)

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\OldFirefox

(32-bit Windows folder names)

C:\Program Files\Mozilla Firefox

to

C:\Program Files\OldFirefox

(D) Run the installer you downloaded in (A). It should automatically connect to your existing settings.

Will Firefox start and run normally?

Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:

• \OldFirefox\Plugins
• \OldFirefox\browser\plugins

Otherwise, there's no reason to keep the old folder except research/curiosity.

They are not getting rid of google as it is still one of the other search engines Firefox comes with, just not global default anymore.

Did you bother reading that support page? If changing the default search engine didn't work as explained, you may have picked up some Malware which is preventing it from being changed by you.

Tried the clean install - no avail, as soon as I entered firefox, i was given yahoo as my home page and search engine. I went back to plugins-exts. Noticed that "many results hub" was back !!!!! I had removed it before ? Removed it again and changed back to google and mozilla home page.

Went in/out several times and happy to say it is remaining google with mozilla homepage. I will wait a few days and verify but u seem to have restored my faith in Mozilla. I am grateful and admit I said some things I shouldn't have BUT time will tell.
