Possible disadvantages of Opera GX Gaming Browser

  • Resource Use Configuration
    While resource limiting is a beneficial feature, configuring these settings can be confusing for less tech-savvy users who may struggle to find the optimal balance.
  • Feature Overload
    For users who prefer a minimalist browsing experience, the multitude of features and customization options might feel overwhelming or unnecessary.
  • Potential Performance Issues
    On lower-spec devices, running the browser alongside resource-heavy games might still lead to performance issues despite the resource management tools.
  • Limited Extension Library
    Compared to more established browsers like Google Chrome, Opera GX has a more limited selection of browser extensions available, which might impact users who rely on specific tools.
  • Niche Focus
    As a gaming-focused browser, its specialized tools and design may not appeal to non-gamers, limiting its appeal to a broader audience who prefer more generalist browsers.

Mozilla Firefox features and specs

  • Privacy-Focused
    Firefox places a strong emphasis on user privacy by offering features such as Enhanced Tracking Protection, which blocks a wide range of online trackers.
  • Add-Ons and Extensions
    Firefox supports a wide array of add-ons and extensions, allowing users to customize their browsing experience to a great extent.
  • Open Source
    Being open-source, Firefox's code is transparent and reviewed by the community, helping find and fix vulnerabilities more efficiently.
  • Cross-Platform Syncing
    With a Firefox account, you can sync your bookmarks, history, and open tabs across multiple devices, making it convenient to transition between them.
  • Resource Management
    Firefox has made significant efforts in optimizing its resource management, which translates to better performance and reduced memory usage compared to some other browsers.

Possible disadvantages of Mozilla Firefox

  • Extension Compatibility Issues
    Though Firefox supports numerous extensions, sometimes they can have compatibility issues after updates, requiring developers to make adjustments.
  • 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.

    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.

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 might be wrong, but it looks like your start page has been set to opera.com/gx . This would explain why resetting your pixelbook still opens this page as the settings are synced in your chrome browser. Source: about 3 years ago
