I visited a website once, and now every time I open a tab, it tries to redirect to that website. How do I remove this "feature"?

more options

Some website called MyStart keeps trying to redirect every blank tab I open to its website. I doesn't seem to work, but I get sick of seeing it try anyway, and it worries me because I don't recall giving it permission to do this. I added the SiteBlock plugin and added the URL it's trying to redirect me to on the blacklist, and even though now my new tabs are blank the way they're supposed to be, I still see the URL in the tab heading, so whatever this thing is, its still on my computer or in my browser. But I can't find it anywhere in my add-ons and extensions and such. It's also not in my programs on my computer.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Does this clear browsing history and saved logins too?

nope, as I said above this only causes you to lose any extensions and open tabs, along with a few settings. History and saved passwords are safely migrated.

There have been several threads about this add-on during the past few months...

It is important to check the Windows Control Panel > Programs and Features to remove the source(s). These may include the following:

  • Incredibar
  • MyStart
  • Web Assistant

After that, restart Firefox and start clearing out its settings as described in the following threads. Many users find it simpler to "Reset" than to take multiple steps to clean-up Firefox. That's up to you.
