However, users with lower-end hardware or those requiring a vast library of extensions might want to consider other options.
Comodo IceDragon 42.0.0.25 is an older version of the Firefox-based web browser developed by Comodo. While it was once promoted for its specialized security features, it is now considered largely obsolete and potentially unsafe for modern use. Key Version Details
Engine Base: This version is based on the Firefox 42 core, which was released in late 2015.
Security Features: It includes integrated tools like SiteInspector (malware scanning for links) and Comodo Secure DNS to filter malicious domains.
Compatibility: It supports legacy Firefox extensions and NPAPI plugins, many of which are no longer supported by modern browsers. Current Status and Risks
Stagnant Development: Development for IceDragon significantly slowed after 2019.
Security Risk: Because version 42 is nearly a decade old, it lacks critical security patches against modern vulnerabilities, rendering it unsuitable for tasks involving sensitive data (banking, personal accounts).
Modern Alternatives: Comodo currently offers the Comodo Dragon (Chromium-based) or newer builds of IceDragon (Firefox-based), though many users have transitioned to mainstream browsers with modern security frameworks like Google Chrome or Mozilla Firefox.

Long before "cookie deprecation" became a buzzword, IceDragon 42.0.0.25 included a one-click Privacy Cleaner. This tool went beyond clearing history and cache; it specifically targeted:
Additionally, the browser came pre-configured with Do Not Track (DNT) headers enabled and a lightweight tracking protection list—essentially an early version of what we now call "Enhanced Tracking Protection."
Icedragon 42.0.0.25 was not a commercial success. It peaked at an estimated 0.02% market share in 2016. Comodo discontinued the project around version 48 (2017), redirecting users back to Comodo Dragon (Chromium).
What did it teach us?
Today, the closest living relatives are:
Neither replicates Icedragon’s aggressive certificate pinning or zone-based DOM storage firewall.
Comodo—now Xcitium—built its reputation on endpoint security: firewalls, antivirus, SSL certificates, and a sandboxing technology called Comodo Internet Security (CIS). By 2015, Comodo had already released Comodo Dragon, a Chromium-based browser aimed at privacy. But Dragon still inherited Chromium’s telemetry and wide attack surface.
Thus Icedragon was born as the Firefox-based counterpart. Version numbers directly tracked Firefox’s releases: 42.0.0.25 = Firefox 42.0 + Comodo patchset 0.25. The goal was not innovation in rendering or devtools, but hardening without breaking the web.
Key date: Firefox 42 launched November 3, 2015. Icedragon 42.0.0.25 followed weeks later.
Firefox 42 used a single content process (e10s was still optional and off by default). Icedragon inherited this, but Comodo added a proprietary process elevation blocker: any child process attempting to request higher integrity levels (Windows) or setuid (Linux) was immediately terminated. This was an early form of anti-exploit behavior.
Before diving into the specific version 42.0.0.25, it is crucial to understand the parent ecosystem. Comodo, a cybersecurity company known for its firewall and antivirus solutions (Comodo Internet Security), ventured into the browser market to create a secure browsing environment. IceDragon was Comodo’s answer to Mozilla Firefox.
Unlike Comodo’s other browser, Comodo Dragon (which was based on Chromium), IceDragon was a Firefox fork. The logic was simple: Firefox offered deep customization and a robust extension library, but it lacked the "hardened" security features that Comodo’s user base demanded. IceDragon aimed to keep the soul of Firefox while grafting on Comodo’s proprietary security tools.
Located on the browser toolbar is a shield icon. When you visit a website—even one you aren't sure about—you can click this icon to launch the Inspector.
This feature performs a real-time, on-demand scan of the webpage using Comodo’s cloud servers. It analyzes the page for:
Because Icedragon changed security semantics before the network stack, several categories of sites broke:
While Firefox had built-in pinning for Google and Mozilla domains, Icedragon shipped with over 400 preloaded pins—including all Comodo-issued EV certificates. The browser would refuse to load any site whose certificate chain touched a Comodo root unless the leaf matched the pinned public key. This broke some misconfigured CDNs but blocked MITM attacks at corporate proxies.
