Your "More System Details" that you shared doesn't show an Ask toolbar. That would leave MapsGalaxy or Advanced SystemCare as the most logical culprits. Does the bar disappear if you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any difference?

Here's how you can change your new tab page:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste newtab and pause while the list is filtered

(3) Double-click the browser.newtab.url preference and enter your preferred page:

• Page thumbnails (default) => about:newtab
• Blank tab => about:blank
• Built-in Firefox home page => about:home
• Any other page => full URL to the page

Press Ctrl+t to open a new tab and verify that it worked. Fixed?

If problems persist, some potential diagnoses and remedies:

If Firefox won't let you edit this setting: you may have something called SearchProtect on your system. This needs to be removed from the Windows Control Panel.

If Firefox lets you save your change but ignores it: one of your extensions may be overriding it. You can review, disable, and/or remove extensions on the add-ons page. Either:

• Ctrl+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 and disable (or remove) anything unknown.

If the change works during your session, but at the next startup is back to the unwanted page: you might have a user.js file in your personal Firefox settings folder (your Firefox profile folder). This article describes how to track down and remove the file: How to fix preferences that won't save.

Any luck?

jscher2000 Thank you so much for your help. When I opened extensions got ride of mapsgalaxy tool bar was GONE!! Yea! Have advanced system care, is that an issue or a bad program? Followed you directions and fixed the new tab situation. Is there an easier way to deal with that? Some time back had changed new tab stuff but didn't think it was the same procedure. This could have been 6+ months ago and know that stuff changes when Fire Fox changes. Have asked this on a different thread (just learned that term) but a web site that I have been to in the past won't open, doesn't come up just a black page, any ideas? In the process of working on this my history has been er raised, not something I really wanted to happen, no am I sure how it happened. Thank you again.

Did you take care of the user.js file?

Your System Details list shows that you have a user.js file in the profile folder to initialize some prefs each time Firefox starts. The user.js file will only be present if you or other software has created this file and normally won't be present.

You can check its content with a plain text editor (right-click: "Open with"; do not double-click). The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• http://kb.mozillazine.org/Profile_folder_-_Firefox

cor-el Thanks for answer this is getting kind of over my abilities to follow and carry out instructions. Found the folder and under user.js.File it said preferences not Fire Fox this was a stand alone line couldn't find it in the list of files. Should I delete it? If yes how?

Note that Windows hides some file extensions by default. Among them .html and .ini and .js and .txt, so you may only see the file name User without file extension. You can see the real file type (file extension) in the Properties of the file via the right-click context menu in Windows Explorer.

Yes, you can delete the user.js file or possibly rename the file or move it to a different location.

Did you inspect the content of the file and used "Open with" in the right-click context menu to inspect the file in Notepad?

You shouldn't double-click the file and that will make Windows try to run the file as a JScript file and that will fail.
