Monochrome Tab browser hijacker Removal Guide

What is Monochrome Tab browser hijacker?

Monochrome Tab is a browser-hijacking app that can read your browsing history

Monochrome Tab

Monochrome Tab is a browser extension that can be found on the Google Chrome Web store, although might also be sometimes downloaded along with freeware apps accidentally. The particular extension is presented as a tool that can help users to create a “calming working space.” According to the creators, it employs plenty of features that can customize users' browsing experience – a clock, weather widget, background to choose from, ability to add various links and social media, etc.

While it may look like a great addition to the web browsing experience, Monochrome Tab is considered to be a browser hijacker,[1] as it changes homepage and new tab settings soon after the infiltration. While it may seem that these changes are not significant (or rather welcomed, in fact), it soon becomes clear that the web browsing experience is no longer the same. This mainly manifests in an increased number of advertisements that users may encounter while browsing the web.

The browser extension may start gathering various user data in the background for commercial purposes. While most of the collected information is anonymous, some details might be considered personal according to local privacy laws.

By no means is Monochrome Tab malicious – it is unlikely to cause any security issues. However, if you have found this app installed on your system without installing it on purpose and would like to remove it, we provide all the required information to do so below.

Name Monochrome Tab
Type Browser hijacker, potentially unwanted browser extension
Distribution Software bundles, ads, third party websites
Symptoms New tab and homepage settings appended to the browser; alternative search results that may include ads
Removal The extension can easily be removed via web browser settings or a few other methods – we list them below. As a precautionary measure, we recommend scanning the system with SpyHunter 5Combo Cleaner security software
Optional steps After removing all potentially unwanted applications, we recommend you employ FortectIntego utility to clean your web browsers and repair any damaged system files

Installation permissions

If your browser is redirecting you to Monochrome Tab, it means that you have a browser extension of the same name installed on your system. If you did not install the app deliberately, it is likely that you have downloaded it accidentally along with other software from third-party websites, or were tricked by a deceptive advertisement on a random website.

Extensions' operation surface is closely related to the browser they are attached to – be it Google Chrome, Mozilla Firefox, MS, Edge, Safari, or Safari. If installed from legitimate sources, the extension would usually ask for the following permissions before it can start being operational:

  • Read and change your data on
  • Replace the page you see when opening a new tab
  • Read your browsing history.

We strongly recommend carefully reading these requirements before installing any browser extension, as it can often tell how intrusive or even malicious the app can be.

Data collection

As we already mentioned, Monochrome Tab collects certain user data. While this practice is not unusual (almost all service providers and applications collect certain data, although it is usually anonymous. The laws of data protection may vary from region to region, thus its classification might also differ. For example, in Europe, websites that do not meet the strict data retention requirements can't even be viewed due to GDPR[2] – General Data Protection Regulation law.

When checking Monochrome Tab's privacy policy, we noticed that developers associate the data they collect as private:

Usage Data may include information such as Your Device's Internet Protocol address (e.g. IP address), browser type, browser version, the pages of our Service that You visit, the time and date of Your visit, the time spent on those pages, unique device identifiers and other diagnostic data.

When using a mobile device, information such as unique device ID and other identifiers might be collected.

How to prevent from getting browser hijacker

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
