Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

The easiest way to get around that is to just set your own homepage. See - How to set the home page

Many of us have disabled the changes to the top part [brandLogo portion] of the Firefox Start Page, so that we don't see that "stuff".

If you feel venturesome, here's how to "fix it". Type about:config in the Location Bar and hit Enter. Accept the "dragons" message to see the advanced prefs screen. Use the Search field at the top to enter the pref mentioned below.

You can set the browser.aboutHomeSnippets.updateUrl pref to an empty string to stop your Firefox from retrieving "snippets" and brandLogo changes. Right-click that pref and select Modify then clear the Value for that pref in the box that appears, then click OK. That will also disable the "snippets" that appear below the Search container on the default homepage.

Then you need to open your Profile folder, via Help > Troubeshooting Information > Profile folder >> Show Folder button. Then close Firefox. With your Profile folder open and Firefox closed ("3-bar" Firefox menu button > Exit/Quit), wait minute or so, then delete the storage\moz-safe-about+home folder in the Firefox profile folder to remove the brandLogo and snippets stored in IndexedDB to make Firefox use the default brandLogo and a default snippet set.

If you should later changes your mind about those modifications, you can reset the browser.aboutHomeSnippets.updateUrl pref via the right-click context menu and use Reset to get the default value back and start using the storage\moz-safe-about+home folder again.
