Smart Blocking Rules

Multiple layers of protection to block threats before they reach you

APIVoid Browser Protection analyzes every URL you visit and blocks suspicious destinations. From risky TLDs to IP-based URLs, phishing domains, and dangerous file downloads.

Block Suspicious TLDs

Block domains ending with a known risky top-level domain, commonly used in phishing campaigns.

Block IP-Based URLs

Block URLs where the host is a raw IPv4 address, a common sign of potentially malicious host.

Block Free Hosting & DDNS

Block domains like pages.dev or free dynamic DNS domains like hopto.org, often abused for phishing.

Block Dangerous Downloads

Block downloads of dangerous file types such as .hta, .bat, .vbs, .ps1, .wsf and many others.

Find clear answers about features, supported browsers, privacy, blocking rules, and how to get the most out of our APIVoid Browser Protection.

What browsers are supported by this extension?

The extension currently supports Google Chrome and Mozilla Firefox.

Can I block downloads of applications and document files?

Yes, you can block downloads of specific file types. For example, you can block application files like EXE and MSI, or document files such as PDF, DOC, DOCX, DOCM, XLS, and XLSX. This allows you to restrict the browser to safer web browsing only and block any potentially risky file type.

If a safe website is blocked, can I exclude it?

Yes, you can exclude a website either from the warning page by clicking the "Exclude domain" button, or from the extension settings under the Exclusions section by adding the domain (e.g., example.com).

Is there any conflict with other extensions?

The extension is designed to work alongside other browser extensions without causing conflicts.

Can I block custom domains or domain extensions (TLDs)?

Yes, you can block specific domains (e.g., example.com) or entire domain extensions such as "info" or "ru". This is useful for reducing your attack surface if you do not typically visit certain TLDs.

Can I import my settings on another browser?

Yes, from the settings page under the Backup & Restore section, you can export your configuration to a file. On another browser, use the Import option to restore all settings and custom rules.

Can I import a Chrome backup on Firefox (or vice versa)?

Yes, the backup file is fully compatible across browsers. You can export your settings on Chrome and import them on Firefox, or the other way around. All your custom block lists, exclusions, and preferences will be restored correctly, independently from which browser they were exported.

Can I reset all settings to default?

Yes, from the settings page under the Reset section, click Reset button to restore all settings to their default values. Important: all your custom rules (if present) will also be removed.

Does the extension make external API calls to check domain safety?

No, the extension currently uses locally stored rules that are automatically updated from our servers. It does not make real-time external API calls, although this may be introduced in future versions.

Do you collect browsing or personal data?

No, we do not collect, store, or track any browsing history or personal data.

Does the extension block ads and web trackers?

No, the extension focuses on blocking suspicious websites and reducing the attack surface. Ad and tracker blocking is not included, as it may interfere with the functionality of some websites.
