Restore your default homepage after an extension hijack

This guide explains how to restore your browser's default homepage after a hijacker changes it via extension, without deleting bookmarks or reinstalling the operating system. Extensions may alter the home page, default search, new-tab page and link destinations while posing as coupon, privacy or PDF tools. For broader warning signs, use Pc Malware Expert's malware removal guidance.

Start with the least destructive fix: record the symptoms, back up bookmarks, inspect extensions, remove the offender, then reset affected settings. Work in one browser at a time and avoid random browser-cleaner downloads, which can introduce more unwanted software.

Spot the hijack and protect your data

First, distinguish a single-site problem from a browser-wide hijack. A new start page, altered results, unfamiliar toolbar or repeated pop-ups are warning signs. Many Australians begin with a Google or Bing search, so wrong results may appear before the home page change is noticed. If the browser has gone wonky in every tab but not another browser, focus on extensions and profiles.

Browser	Main homepage setting	Extension manager
Chrome	Settings > On startup	chrome://extensions
Edge	Settings > On startup	edge://extensions
Firefox	Settings > Home	about:addons
Safari	Settings > General > Homepage	Safari > Settings > Extensions

Before making changes, confirm that bookmarks and passwords are backed up or synchronised. If the browser account may have been abused, change its password from the official provider, then review linked devices. Test with a fresh profile; repeated redirects there point to malware or a managed policy rather than one bad website.

Review extensions and synced settings

Open the extension manager: chrome://extensions, edge://extensions, about:addons in Firefox, or Settings > Extensions in Safari. Check recently added items and anything able to change your homepage, search engine or new-tab page. Remove suspicious extensions rather than hiding their toolbars. Pc Malware Expert's overview of potentially unwanted programs can help identify nuisance behaviour.

A hijacker can return through browser sync. Many Australian households use a Google or Microsoft account across a desktop, laptop and tablet, so reinstalling on one device means checking all linked devices. Sign out, secure the account and remove the extension from its source. Treat clipboard, downloads and browsing-history permissions as serious warning signs.

Reset the homepage in your browser

Once the extension is gone, set the home page in browser settings. Choose a specific page under On startup in Chrome or Edge, Home in Firefox, or General > Homepage in Safari. Delete unfamiliar startup entries too, because a redirect may remain even after the offending extension is removed.

If changes keep disappearing, use the built-in reset. Chrome and Edge provide Reset settings, while Firefox offers Refresh Firefox under Troubleshooting Information; Safari needs manual homepage and extension changes. A reset may disable extensions and reset search choices, but it cannot remove malware or recover ransomware-encrypted files.

Remove redirects and leftover traces

Next, remove items that keep sending traffic back to the hijacker. Revoke unexpected notification permissions, delete suspicious bookmarks and inspect desktop shortcuts. Their Target field should point to the installed browser, not a random script or advertising domain. Also check the default search engine, since redirectors often change it along with the home page.

Run Windows Security or the browser's built-in safety scan after removing the extension, then clear cached files for the affected browser. If every browser and device is redirected, inspect DNS and hosts-file settings too. Australian providers such as Telstra, Optus and iiNet normally leave homepages under customer control, so a broadband-wide redirect is not a normal ISP feature.

Clear policies and hidden browser changes

Check whether the browser says it is managed. Workplaces in Sydney, Melbourne and Brisbane often administer Chrome or Edge through central policy, especially for customer or financial data. If it says “Managed by your organisation,” ask IT to review extensions, homepage and search restrictions rather than bypassing company controls.

On personal devices, inspect browser profiles and account settings for unfamiliar profiles, synced extensions or start-page entries. Test a clean profile to learn whether the problem sits in the profile or operating system. Revoke unwanted site permissions, and clear cookies for the hijacked domain rather than every site you use.

Handle shared devices and wider infections

Windows users will usually meet this problem in Chrome or Edge, while many Mac users rely on Safari, which stores extensions and settings in a different place. On shared family laptops and tablets, give each person a browser profile and avoid leaving a hijacked session signed in. Sign out of unknown browser accounts after use.

Public Wi-Fi at Melbourne and Sydney cafés, airports and hotels is convenient but poor ground for prompts claiming you must install a “security” extension. Download tools only from the official store or vendor site. If redirects survive a clean profile and scans, deeper malware may be present; ransomware recovery follows a separate process, as shown in the Virlock removal guide.

Prevent another homepage takeover

Prevent recurrence by updating the browser and extensions, enabling Safe Browsing or equivalent protections, and removing extensions you no longer use. Install only from official stores, and reject unsolicited search-bar or PDF-converter prompts. Review browser account devices regularly, because synced settings can restore a removed hijacker.

Keep operating-system security current and run periodic scans, especially after downloading free utilities. Australian users can use ACSC Scamwatch guidance when an extension or alert uses a convincing scam narrative. A reliable recovery sequence is extension removal, homepage reset, search cleanup and a check of synced or managed settings; if redirects persist, isolate the device for deeper cleanup.
