Okay so I installed adware on my pc. These malicious softwares change the new tab setting every time I restart my computer, so how can I "lock" the settings and not let them be changed from default? If this is impossible, why not make it a feature?

Hi jocfla,

Whilst it is possible to, in a way, lock some settings, this isn't probably the solution you're looking for (and it might not help, depending on how sophisticated the adware you have is). I would recommend removing the adware you've installed first.

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

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has an antivirus built-in already.

Good luck!

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.


These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backups of files that you choose.

The browser.newtab.url pref is no longer supported in Firefox (41+), so it is no longer possible to set the new tab page via this pref.

You can look at this extension to set the new tab page:

You can set the new tab URL setting via the Options/Preferences of the extension on the about:addons page.

You can look at this extension if you use the home page as the new tab page.

Classic Theme Restorer includes this feature as well. In current CTR versions (1.3.9+) you find "New tab page url" in the Tabs (1) section.

You can use pages like these:

  • the default new tab page with the tiles is about:newtab
  • the default home page is about:home
  • for a blank page use about:blank
  • for Super Start use about:superstart
  • use the URL of a web page

See the about:about page for available about pages.
