Remove Unwanted Browser Extensions and Hijackers

Sketchy converter sites and fake "FLVTO app" installers often plant browser extensions: junk search toolbars, new-tab hijackers, and ad injectors. This page walks you through auditing and removing them in Chrome, Edge, and Firefox.

Step 1: open your extensions page

• Chrome: type chrome://extensions in the address bar, or go to the three-dot menu, Extensions, Manage extensions.
• Edge: type edge://extensions in the address bar, or the three-dot menu, Extensions.
• Firefox: type about:addons in the address bar, or the menu, Add-ons and themes.

Step 2: audit every extension

Look at each entry and ask: did I install this on purpose? Remove anything you do not recognize, especially entries with vague names ("Search Helper", "Fast New Tab"), no real icon, or that appeared right after a sketchy download. Click Remove and confirm. Restart the browser afterward.

Red flags of a hijacker

• Your search engine changed without asking.
• New tabs open a strange search page instead of a blank page or your chosen homepage.
• Extra toolbars or sidebar panels appeared.
• Ads appear on pages that never had them, or download buttons multiply.

Step 3: verify search, homepage, and new tab

Open your browser settings and confirm the search engine, homepage, and new tab page are still the ones you chose. Hijackers change these during installation; removing the extension does not always revert them.

Step 4: reset settings as a last resort

• Chrome: Settings, Reset settings, Restore settings to their original defaults.
• Edge: Settings, Reset settings, Restore settings to their default values.
• Firefox: type about:support, then Refresh Firefox.

Resetting keeps your bookmarks and history but clears extensions, pinned tabs, and customized settings.

Step 5: run an antivirus scan

If the junk arrived via an installer (not just a webpage), a browser cleanup alone may not be enough. Run a full scan with your antivirus and quarantine anything it finds.

How it got there

Usually it was a fake download button on a clone converter site, or a "FLVTO app" installer from an unrelated source. The real browser tool installs nothing: no extensions, no programs. Learn to spot fake download buttons so it does not happen again.

Frequently asked questions

Is one bad extension enough to cause problems?

Yes. A single hijacker can change your search engine, inject ads, and track your browsing. Remove it and verify your settings.

Why did my search engine change back?

The hijacker extension was still installed, or an installer replanted it. Remove the extension, fix the search setting, and run an antivirus scan.

Does resetting the browser delete my bookmarks?

No. Chrome, Edge, and Firefox resets keep bookmarks, history, and saved passwords while clearing extensions and customized settings.
