Tabs opening by themselves.
bold textRecently Firefox has started opening a new tab all by it's self. I didn't ask for one, don't need one. It's also switching to an open tab without input from me. For instance, I am here trying to ask a question and it jumped to a tab that I have open to check the weather. My mouse hasn't moved, I haven't hit the tab key, nor have I touched the screen. What is going on? I uninstalled and reinstalled and it's still doing it. It's driving me nuts. I'm running the latest version on Windows 10 64 bit.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
Not only did this not solve my problem, your instructions don't match my version of FF. There is no "tools" option. I had Add-ons and themes, Settings and More Tools. Nor could I find hardware acceleration or userChrome.css.

Is this to the same web address, different addresses? What does the unwanted page contain? ads? . . . .
Does this happen when the browser is not open?
Start Firefox using Troubleshoot(Safe) Mode {web link}
A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:
- Click the menu button
and select Options (Windows) or Preferences (Mac, Linux).
- Select the General panel.
- Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.
- Uncheck Use hardware acceleration when available.
- Close Firefox completely and then restart Firefox to see if the problem persists.
