To be more specific, you can consider K-Meleon as an alternative to Firefox, as it offers almost the same features while consuming minimal system resources.

By default, it uses DuckDuckGo as a default search engine. However, you can change this setting anytime.

5. UR Browser– Privacy Suite with Built-in VPN and Ninja Mode

viewing main dashboard of ur browser

Think of UR Browser as a lighter version of Chrome for your 32-bit system. This browser uses limited resources and offers the same benefits as Safari and Chrome but with better security and some innovations.

UR Brower supports three privacy suites with different types of protection:

  • Low Privacy Level: Only supports HTTPS Redirect and Anti-Fingerprinting.
  • Medium Privacy Level: Includes Low Privacy level features and also blocks Ads and Trackers.
  • High Privacy Level: Includes Medium Privacy level features, blocks cookies, and also supports Ninja mode.

In my case, I tested the High Privacy Level suite, which consequently blocked 2 trackers, 28 ads, and 59 cookies.

activating high privacy level of ur browser

Additionally, the Ninja mode feature of the High Privacy Level suite allows you to browse privately. In this mode, all your browser history, search history, and store cookies get erased as soon as you close the tabs.

However, it keeps the bookmarks and the downloaded files after quitting the tabs.

using ninja mode of ur browser

This isn’t a new feature since all popular browsers offer an incognito mode. However, UR Browser permits you to use the private or Ninja mode and the normal mode within the same window, which is quite impressive!

It also comes with a built-in VPN that hides your IP address and spoofs your location to protect your online privacy.

This browser also has its own Download Manager, which separately organizes images, videos, audio, and documents. Specifically, in terms of downloading files, it utilizes advanced parallel technology. It results in a 4x faster download speed than usual.

Moreover, UR Browser also allows you to search for specific downloaded files within the Manager.

viewing downloads manager of ur browser

Notably, every time you download something from the internet, it undergoes the built-in virus scanner and is verified for threats. If UR Brower finds the file suspicious, it flags it and generates an alert for the dangerous file. The same goes for browsing websites.

To protect your privacy even more, it disables text prediction on web searches, automatic updates, and password filling. Other than this, you can use its Settings window, the same that Chrome supports, and tweak the options.

viewing settings of ur browser


  • Supports multiple privacy levels: Low, Medium, High
  • Contains a Built-in VPN, Ad Blocker, Cookies Blocker, and more
  • Offers an integrated virus scanner
  • Uses advanced parallel technology for faster download speed

Similar to Pale Moon, you can set permissions for the current website with the second option. This includes accessing locations, installing add-ons, loading images and stylesheets, blocking pop-up windows, and more.

  • Provides an extensive collection of add-ons for customization
  • Allows creating and managing of separate user profiles
