You might need to try Firefox's Safe Mode. In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.
</p><p><em>If Firefox is not running:</em> Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)
</p><p><em>If Firefox is running:</em> You can restart Firefox in Safe Mode using either:
</p>
<ul><li> "3-bar" menu button &gt; "?" Help button &gt; Restart with Add-ons Disabled
</li><li> (menu bar) Help menu &gt; Restart with Add-ons Disabled
</li></ul>
<p>and OK the restart.
</p><p><em>Both scenarios:</em> A small dialog should appear. Click "Start in Safe Mode" (<em>not</em> Refresh).
</p><p>Can you regain control?
</p>This is the third similar report I've read from a Windows user in 5 minutes, so something must be go2020-07-28T03:47:56-07:00jscher2000https://support.mozilla.org/de/questions/1296858#answer-1336722<p>This is the third similar report I've read from a Windows user in 5 minutes, so something must be going around. Do you want to share your extensions list? You can copy/paste it from the Troubleshooting Information page. Either:
</p>
<ul><li> "3-bar" menu button &gt; "?" Help &gt; Troubleshooting Information
</li><li> (menu bar) Help &gt; Troubleshooting Information
</li><li> type or paste <strong>about:support</strong> in the address bar and press Enter
</li></ul>
<p>Scroll down past "Application Basics" and "Firefox Features" to "Add-ons". Then you can select and copy the table that follows (not the entire page, please, that's too much information) using either Ctrl+c or right-click &gt; Copy and then paste it into a reply. It will be messy, but we're used it.
</p>hi, firefox ships with google as the default engine - if yahoo is showing up without your knowledge 2020-07-28T03:43:24-07:00philipphttps://support.mozilla.org/de/questions/1296858#answer-1336717<p>hi, firefox ships with google as the default engine - if yahoo is showing up without your knowledge that might be a sign of adware or a malicious addon being present on your system.
</p>
<ol><li>please go to the firefox <em>menu ≡ &gt; addons &gt; extensions</em> &amp; remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc).
</li><li>also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there.
</li><li>finally, run a full scan of your system with different security tools like the <a href="https://www.malwarebytes.org/antimalware/" rel="nofollow">free version of malwarebytes</a> &amp; <a href="https://toolslib.net/downloads/viewdownload/1-adwcleaner/" rel="nofollow">adwcleaner</a>, which are specialised in adware and browser hijackers.
