  • Slower Performance on Some Sites
    In some cases, Firefox may perform slightly slower than competitors like Google Chrome, particularly with sites heavily optimized for Chrome.
  • Market Share
    Firefox holds a smaller market share compared to giants like Chrome, which can sometimes result in websites being less optimized for Firefox.
  • Limited Native Features
    Some features that are built-in with other browsers need to be added via extensions in Firefox, potentially making the setup process longer.
  • Frequent Updates
    Though generally positive, Firefox's frequent updates can sometimes introduce bugs or lead to unexpected behavior, needing rapid release fixes.

    Being a community-driven project, LibreWolf may have less comprehensive support and slower updates compared to mainstream browsers.
  • Learning Curve
    Users unfamiliar with advanced browser customization may find it challenging to adjust settings to their liking.

    Some add-ons and extensions available for Firefox might not be fully compatible or require additional configuration to work correctly with LibreWolf.

    I adore Firefox's functionality and the fact that it is open source software that might be created by tens of thousands of people worldwide. You can utilize features that aren't accessible on rival products like Chrome because it is open source.

    👍 Pros:    Open-source|Free|Fast

The 7 best web browsers in 2025
Firefox is a lightweight browser and doesn't require much space or memory, meaning it can operate smoothly even on lean machines. But it doesn't compromise on utility. It's packed with supplementary tools, like a handy PDF editor, a tracker and cookie banner blocker, a read-it-later app, and more. I also like that you can isolate tabs on Firefox so they act in a new,...

Avoid The Hack: 6 Best Privacy Browser Picks for Windows
Many tweaks, both basic, and advanced, should be made before Firefox can be considered a private browser. While vanilla - or otherwise un-configured - Firefox is arguably better for privacy than Google Chrome or Microsoft Edge, Firefox doesn't come especially configured for optimal (or maximum) user privacy out-the-box. This isn't a difficult task and just takes a chunk of...

You can also expect good performance from Firefox, though you might run into a rare compatibility issue.

LibreWolf Reviews

    Absolutely amazing!

    LibreWolf just makes my work easier and faster, it only needs some configuration and you're done. To be honest uBlock-Origin is the best Ad-Block in my opinion, it's the only one I can trust for privacy!

    🏁 Competitors: Brave, Vivaldi, Opera, Whale, Microsoft Edge
    👍 Pros:    Privacy

Brave Alternative - 8 Privacy-Focused and Reliable Options
Unlike Brave, LibreWolf doesn’t collect telemetry data for maximum privacy. I also experienced that it has a lighter impact on system resources due to the minimum background process compared to Brave.

Of course, with specially tailored browsers like Tor Browser, LibreWolf, and Mullvad, you lose the flexibility of accessing it on mobile devices. So, you can choose a separate browser for your smartphone, or pick one that supports all your devices.

The 11 Best Web Browsers Not Based on Chromium
One of LibreWolf's main attractions is its staunch commitment to user privacy. It ships with a no-telemetry policy out-of-the-box, ensuring that your browsing habits stay your business. This places it a cut above many counterparts, including Firefox, which requires users to manually opt-out of telemetry and data collection.
