A browser or AI extension is a tool designed to enhance the functionality of your internet browser. They are a small programme that adds specific features to the browser. These extensions can perform various tasks, such as auto-correction, blocking ads, SEO recommendation, managing passwords, or altering the appearance of websites. They work by installing the browser’s existing features and changing the way information flows during your online activities.
When you install a browser extension, it becomes a part of your browser, affecting how it processes data from your computer and the internet. The extension customises your browser’s appearance or behaviour, essentially tweaking how it handles tasks like uploading and downloading information.
However, these extensions usually need large permissions in your browser to work. Some ask for access to almost everything you do online, including visited sites, keystrokes, and even passwords. This can be risky because a bad extension or an insecure browser might expose your data, leading to privacy and security problems. So, In this article, we’ll cover what you need to know about extensions how to be careful and check what permissions a browser extension requires before adding it, and how to know if an extension is safe.
What AI Browser Extensions Are Used For
Despite potential security concerns, extensions offer numerous advantages
1. Increase Productivity
Extensions like Bard AI Extension can do more by teaming up with Google apps. It can help you find out about flights and hotels in real time to plan your trips. So, it talks to other Google apps through extensions to give you these handy details. This means Bard becomes more useful and can provide you with more personalised information.
Also, extensions like “Compose.ai,” “Grammarly,” and “SurferSEO Content Editor” enhance your browsing experience by offering advanced functionalities. “Compose.ai” helps in content generation by using AI. “Grammarly” increases productivity by offering grammar and writing suggestions, ensuring error-free articles.
SurferSEO Content Editor contributes to content creation with recommendations for optimisation. These extensions provide support for users engaged in writing and content-related activities. Their combined features enable you to produce high-quality content.
2. Ad Blocking
Ad-blocking extensions prevent unwanted advertisements from appearing during online browsing. They work by recognising and filtering out elements of web pages that are identified as ads. This enhances your experience by reducing clutter, improving page loading times, and reducing distractions.
3. Theme and Style Modification
Extensions for theme and style modification allow you to personalise the appearance of your browser. These extensions have features like dark mode, custom colour schemes, or unique themes.
4. Note-taking and Organization
Extensions designed for note-taking and organisation speed up how you manage information. You can capture and organise notes directly within your browser, making research, project planning, or any online activity that requires documentation easier. Extensions like the Todoist extension let you stay organised.
5. Security Enhancements
Some security extensions ensure your online safety by adding features like virtual private network (VPN) services, malware protection, and encryption protocols. This will help you safeguard your data and protect against malicious threats.
6. Password Management
Password management extensions increase your online security by securely storing and auto-filling login credentials. You can create complex and unique passwords for each website without the need to remember them. These extensions often employ encryption and other security measures to protect sensitive information, speeding up the login process while ensuring password security across various websites.
How Safe Are Browser Extensions?
Extensions whether AI themselves are not inherently dangerous, but their safety depends on various factors, such as the source from which they are obtained, the permissions they require, and the reputation of the developer. Extensions installed from official stores, such as the Chrome Web Store or Firefox Add-Ons portal, undergo screening processes that reduce the likelihood of malicious content.
However, extensions from third-party websites may lack such scrutiny, increasing the risk of security threats. They can compromise your privacy, security, and data. They can engage in activities like data theft, ad fraud, or even introduce malware. Here are the dangers extensions can pose:
1. Malicious Intentions
Extensions with malicious intent may disguise harmful activities, such as data theft or ad fraud. You unsuspectingly install these extensions, exposing yourself to security risks as the extensions carry out malicious actions in the background, compromising sensitive information and personal data.
2. Privacy Concerns
Some extensions often request extensive permissions, raising privacy concerns as they may access and collect user data. This can include browsing history, login credentials, and personal information. In this case, you need to be cautious about the information you grant access to, as browser extensions with lax privacy practices can lead to unauthorised data exposure.
Consider the case of Web of Trust (WoT), a seemingly non-malicious extension initially available on various browsers. A German website exposed WoT for allegedly selling user data to third parties without adequate anonymization, prompting Mozilla to remove it from their store. Although the extension was later reinstated, this incident highlights the potential privacy risks associated with extensions
3. Outdated Security
Extensions that lack regular updates may have vulnerabilities that hackers can exploit. Outdated security features and missing patches make these extensions susceptible to cyber threats, putting users at risk of various online attacks.
4. Data Selling
Certain extensions engage in unauthorised data collection and may sell users’ private information to third parties without explicit consent. This practice poses serious privacy risks, as sensitive data such as browsing habits, passwords, and personal details can be exploited for various purposes, including targeted advertising or even identity theft. Users should be vigilant about the data-handling practices of extensions to protect their online privacy and personal information.
5. Account Hijacking
Malicious actors often target popular extensions, either by hijacking existing ones or by acquiring them, to distribute malicious updates. This can lead to account hijacking as unsuspecting users install compromised extensions, unwittingly granting unauthorised access to their accounts. The consequences may include data breaches, unauthorised transactions, or other security compromises.
6. Resource Consumption
An AI extension with poor optimisation and inefficient coding can excessively consume system resources, resulting in sluggish browser performance. High resource consumption may lead to slower page loading, unresponsive interfaces, and even browser crashes. This negatively impacts the overall user experience, causing frustration and hindering efficient web browsing. You should be mindful of the resource footprint of your installed extensions
7. Extension Permissions and Risks
Granting extensions unnecessary and extensive permissions can compromise user security. Extensions with access may extract sensitive information or perform actions beyond their intended scope, posing significant privacy and data security risks.
Major browsers like Google Chrome, Microsoft Edge, and Mozilla Firefox aim to manage extension permissions, allowing you to limit access. Some extensions can request permission only for the current tab rather than all websites. However, challenges persist, especially if an extension demands extensive access to basic features.
Chrome faces constant scrutiny due to its high number of users, but Firefox, lacking system permissions, automatically grants extensive access to every installed extension.
This loophole is exploited by malicious extensions, as seen in instances like Avast and AVG’s Online Security extensions recording and selling user data in 2019.
In 2018, Google removed four extensions with substantial downloads after they secretly clicked on-page ads. Microsoft Edge, despite its permission system, often requires broad access for it to work well.
Extensions like Microsoft Editor and Grammarly, while they have no record of being malicious, require too much access to all pages visited. Granting such permissions poses a high level of trust and raises concerns about user privacy.

How to Know If Your Extension is Safe
Knowing if your extension is safe is important to protect your online privacy and security. Safe extensions protect your personal data, passwords, and browsing activities from potential threats. By knowing the legitimacy, reviews, and permissions of an extension, you reduce the risk of exposing sensitive information to malicious actors. Here is how to find out if an extension is safe:
1. Permissions Evaluation
Ensuring the safety of a browser extension involves a careful review of the permissions it requests. When installing an extension, take a close look at the permissions it seeks. Low-risk permissions, like organising other extensions or managing themes, are generally safer. Medium-risk permissions for accessing data on visited websites warrant cautious consideration. High-risk permissions, allowing access to all online and offline data, demand careful evaluation.
2. Research Developer
To ensure extension safety, verify the developer’s legitimacy. Look for a professional developer with a public profile or website, preferably with an HTTPS connection. If the website lacks essential security features or displays vague privacy policies, consider avoiding the extension. Checking other extensions by the same developer provides insights into their reliability and experience.
3. Check the User’s Reviews
User reviews serve as a good way of knowing if an extension is safe. Examining experiences shared by others in the Chrome Web Store gives insights into an extension’s performance and potential issues. However, it’s essential to be careful, as fake or unhelpful reviews may skew perceptions.
4. Update Frequency
The frequency of updates offers a reliable indicator of an extension’s ongoing maintenance and commitment to security. Extensions regularly updated by developers demonstrate responsiveness to emerging threats and a commitment to improving functionality. On the other hand, extensions lacking recent updates may pose security risks, as they might lack important improvements. Extensions with consistent and recent updates contribute to a safer browsing experience.
5. Reduce Extensions
Refrain from installing an excessive number of browser add-ons. While extensions offer functionality, each one increases the potential risk. A crowded list of extensions not only clutters your browser but also increases the chances of having security vulnerabilities. By restricting the number of installed extensions, you minimise the attack and reduce the likelihood of malicious activities.
6. Check the Source Code
If you are familiar with programming, scrutinising an extension’s source code provides an additional layer of security verification. Using tools like the Chrome extension source viewer, examine the codebase for any signs of malicious or risky elements. A thorough code review helps identify any attempts to compromise data security or monitor user activity.
