Usually, the problem is an extension. You didn't share your Firefox browser data with the forum, so I'll give you a general suggestion:

You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then cast a critical eye over the list on the right side. All extensions are optional. If in doubt, disable.

Don't limit yourself to official Yahoo extensions, usually it's an "affiliate" which Yahoo pays for traffic, whose software you accidentally installed as part of a free software bundle.

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?

And to clean up any other garbage that arrived at the same time:

(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 surface undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here. (If in doubt, feel free to post a screenshot.)

(2) You can search for programs that don't advertise themselves so obviously 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.

Thanks, but same response you have posted in many other questions, I had tried all of these before posting the question. The problem still occurs and only happens on Mozilla. Back to using IE and Chrome.

It does not matter what page I go to. I follow all of the steps, do not see it anywhere. Close Mozilla and re-open it. Go to search and check and Google is the default, Yahoo is no option. Then if I do any search (typed single word various times) and the search ends with Yahoo. Go to options > search and default search engine is set to Search for Firefox Search Engine. No Yahoo as n option at all.

Yahoo or something is forcing it to be used despite everything done to avoid/prevent it.

Hi Peter, Any chance of answering the initial question and posting the information. It may help us

Please post the full address of one of the Yahoo results pages. Extra parameters added to the basic URL sometimes help identify the culprit.

Also did you run all the tools suggested in the article

• Troubleshoot Firefox issues caused by malware
  • and if so what was reported ?

By the way what is and do you need

Pando Web Plugin

From a quick websearch it looks like it could make unexpected actions.

Does not matter what I search for. Just doing any search and it shifts to Yahoo. Search may be valid, but I do not want Yahoo to do the search and have changed it many times to Google and I do not have Yahoo anywhere on the PC. Still leads me to think problem with Mozilla

Attached is screen capture with top image being when I first opened Mozilla and second when I simply wrote test and hit search. Here is link from search: http://search.yahoo.com/search?ei=utf-8&fr=tightropetb&p=test&type=25003_091116

By the way, I did try many of the suggestions Troubleshoot Firefox... and apparently have not resolved issue.

It looks like you selected Chosen Solution - was that in error and you still need support?

Hi Peter,

Maybe you have malware or a toolbar related to the word tightrope or tightropetb I did find this very old post about someone having issues with Firefox doing yahoo searches

• tightropetb ,what is it?
  https://www.newbiesforum.com/phpbb3/viewtopic.php?t=10316

Also please check your Firefox shortcut icon's properties of the by right clicking it and looking if anything is added after where it says firefox.exe

Additionally start Firefox by using a run command directly. Use keyboard shortcut

WinKey + R 

to open a run dialogue (Hold the key with a Windows logo on and press the R key). Then type in

firefox

and press Enter. That will run Firefox without any specific address being loaded. Does that open up ok and let you search with your chosen search engine.

I am sure you are already aware of this but for the benefit of anyone else following this note how to set your chosen search engine:

• Change your default search settings in Firefox

You incorrectly marked my last post as a solution, I will unmark that as you still have problems.

problem not solved, When do I choose solution? Thought I had just been selecting post reply.

How do I check icon's shortcut's in windows 10? I do not have Mozilla set as shortcut on screen, but do have on toolbar. Tried via toolbar and did not see option of to what it is linked.

I did try the WinKey+R and tried firefox and do appear to not have the Yahoo issue when accessing this way.

It would be worth trying with all those tools listed, some of them may even manage to check and correct faulty shortcuts. You may have managed to remove malware or adware, but if not these problems could come back again.

If you right click on the taskbar shortcut in Windows 10 it will display information including the name of the program in this case Firefox. If you then right click on that you get a Properties option. Click the properties and a properties dialogue opens with a shortcut tab, open that and you will see Target That will end with

firefox.exe"

It should not have anything other than the double quotation mark after it. If for instance it has a web address after it then Firefox will open that.

Tried with Mozilla opened with WinKey+R and see this as Target and this is the shortcut: C:\Program Files (x86)\Mozilla Firefox\firefox.exe". No problem

Tried opening from taskbar and when doing search I do get the Yahoo again now, but have the same different with link: C:\Program Files (x86)\Mozilla Firefox\firefox.exe"

There are many tools listed. Any priority as to which I should try first? Have done many, but obviously not the one to solve the problem yet.

Shortcuts

If using a simple

firefox

From the run dialogue (WinKey+R ) OR a shortcut

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" 

Works then it quite possibly is a modified shortcut that is the problem.

Are you able to identify what the faulty shortcut is ? What about just right clicking the Firefox Program firefox.exe and dragging that to the Desktop, where it will give the option to create a shortcut. That should then work ok to start Firefox.

Tools

The malware help article lists five tools it is well worth using an up to date copy of each one

• Malwarebytes' Anti-Malware Free
• SuperAntispyware Portable Scanner
• Microsoft Safety Scanner
• Anti-Rootkit Utility - TDSSKiller
• AdwCleaner (see this alternate AdwCleaner download page for more information)

Note: Certain malware components can only be removed inWindows Safe Mode

Yes it may take some time to use all of those tools, but they each find different things and it could be time well spent.

Tried adding it as a shortcut, but then still seems to identify this issue as it converted to Yahoo. Only seems to work if I do the WinKey+R option. I checked and it looks like the malware tools are at a cost. If Mozilla is allowing this malware as I do not have problem with others, then Mozilla should update their software to block this issue.

It appears you have shown Firefox will work ok unless you use a corrupted shortcut.

If that is the case it is up to you to sort that out. We may be able to offer advice, but changing Firefox will not fix your problem. (At least not without removing useful basic features.)

The tools will take time to run.

Yes it will require time and effort from you. There is no financial cost they are all free of charge software, You may not have deliberately made changes but in all probability downloaded some bad software that did. If that is still active it could still have further bad effects on your computer. It is not unknown for malware to use keyloggers and then be able to steal your money, if you use online banking or online shopping. Or to use ransomware that makes your computer and its personal data useless.
