Other than that, you can create macros to automate certain tasks and save valuable time. Advanced search is also available, allowing you to search for bookmarks or perform a Google search easily.
Overall, this is a perfect browser for older computers, since it requires only 100MB of memory and 20MB of RAM to run, but unfortunately, it lacks many features that modern browsers have.

This customized browser is based on the Chrome rendering engine and has many features that will make managing and playing various media sources easy.
Torch has a built-in YouTube-based streaming service called Torch Music. This page allows you to easily access your favorite songs on YouTube, and have them all in one place.
Besides YouTube videos, the browser also gives you access to more multimedia content, from other sites.
What some users will like the most are Torch’s built-in download options. Namely, this browser has a built-in button for downloading YouTube videos, as well as its own torrent downloader.
So, if you want to download your favorite music video or some file from a torrent, you basically don’t need to install any additional tool.
We must warn you to be careful when downloading online content because you can easily get into legal trouble, so it is advisable only to download legal stuff.
Regarding the user interface, you shouldn’t have any problems using this browser. Besides the main zone, where website content is displayed, Torch’s UI also has two drop zones on the right and left.
The left drop zone is used for sharing content and allows you to basically share anything you select to social media and other channels (videos, text, images, etc).

Lunascape Orion – Basic features & low resource consumption
Can’t decide between Firefox, Chrome, IE, or Safari? Well, what if we tell you that you can have all four within one program with this lightweight browser for PC.
That’s exactly what Lunascape Orion is all about – having Trident (Internet Explorer), Gecko (Firefox), or WebKit (Safari and formerly Chrome) all bundled into a single browser.
You can set one engine to be used every time you open Lunascape Orion, but you can also switch engines any time, simply by pressing a button.
This could be extremely useful if a certain web page is not supported in one browser, so you can always switch to another engine, and access the page.
It can be very practical, but some say that its performance can suffer because of that.
The browser appears to have a very poor performance on some computers, and that’s basically its biggest problem.
Besides the ability to switch between three different engines, Lunascape Orion has all features of a standard browser. You can save bookmarks, look for URLs, and it even supports the RSS feed.
Other great features:
- Up to 25% more than other browsers
- Available for Windows and Mac

Maxthon – Built-in ad blocker and screen capture tool

Another great thing about Maxthon is that it uses its own cloud services to sync users’ data between devices.
While this isn’t an unusual sight with the major browsers, not many ‘smaller players can brag about this feature.
To make Maxthon sync your data on all devices, you need to create an account on its cloud-based service, Passport, login, and you’re good to go.
Maxthon also sports an unusual user interface for the majority of browsers. It features a toolbar placed on the left side of its window with buttons for Favorites, Downloads, RSS feeds, and notes.
Just like Lunascape, Maxthon is also a multi-engine browser, as it can use both Internet Explorer’s Trident, and Google Chrome’s Webkit engine.
Other great features:

- Password manager
- Ability to easily take screenshots
- Split screen view for tabs
SeaMonkey – Open-source browser
SeaMonkey is an open-source web browser, that has been around for more than 10 years.
Expert tip:
SPONSORED
Some PC issues are hard to tackle, especially when it comes to missing or corrupted system files and repositories of your Windows.
Be sure to use a dedicated tool, such as Fortect, which will scan and replace your broken files with their fresh versions from its repository.
This is probably one of the most versatile browsers you can find on the market because it offers much more than just regular web browsing.
SeaMonkey features its own built-in email client, and a built-in chat, and even allows you to develop some simple web pages with its built-in editor.
This might come in handy if you want to keep all your services in one place, run fewer tabs in your browser, and therefore save more resources.
Besides providing some basic features you would normally get in any web browser, SeaMonkey also has some additional abilities.
It provides a password manager, voice interaction, customizable toolbars, and the ability to restore sessions.
Since this is an open-source browser, basically anyone with some knowledge of coding and the will to work on the browser can do so.
Because of that, SeaMonkey doesn’t seem to be the most stable and reliable browser out there, as users might notice occasional performance issues.
But if you want to save some time by having everything you use daily in the same place, and at the same time consume less energy and memory, you should give SeaMonkey a try.
Other great features:
- Open source
- Available on all major desktop platforms
- Popup blocker
- Incredibly simple to use
Midori – Doesn’t collect user data
Midori is an open-source browser, that should satisfy not-so-demanding users.
This browser has solid pack features, but also consumes fewer resources than some of the mainstream browsers, which can seal the deal for some people.
Some of the most important features of Midori are HTML5 support, bookmarks, RSS support, a spell checker, anonymous browsing, etc.
Speaking of HTML5, here is a list of the best editors on the market. You’ll become an expert on the matter!
It also ships with some additional options, like tabbed browsing, the ability to change privacy settings, font/display settings, and startup settings.
Speaking of privacy settings, Midori uses DuckDuckGo (a search engine that doesn’t collect or share user info)as its default search engine.
Of course, you can change this later, if you want to switch to a mainstream search engine.
Perhaps the most appealing thing about Midori is its simple user interface, which will delight all lovers of the minimalist approach.
The browser is very light, so it should be very easy for you to get accustomed to it. Its user interface consists of the search bar, and the bookmarks bar, while content takes up most space.
So, we can call this browser Firefox’s younger brother, even though the two browsers are not related.
Other great features:
- Available on all desktop platforms and Android
- Great privacy control
- Built-in ad blocker
- Productivity features
Falkon – Great on Linux
Another lightweight browser that deserves your attention is Falkon. The browser is built on QTWebEngine.
The browser has been present since late 2010, and it was called QupZilla, but it was rewritten in C++ using the Qt Framework, and it has since changed its name.
The browser is a part of the KDE project, so it already comes preinstalled with many Linux distributions. Of course, the software is available on multiple platforms, and you can find it on almost any platform, including Windows.
As for the features, you can find all the basic features available such as bookmarks, history, and tabs. The browser comes with an AdBlock plugin preinstalled, so you won’t have to deal with ads ever again.
Overall, this is a great browser for users who need minimalistic and lightweight software to surf the web. Since Falkon uses its browsing engine, the number of available extensions is limited, which might be a problem for some users.
Other great features:
- Minimalistic
- Available on multiple platforms
- Has only the most essential features
- Built-in adblocker
Firefox – Resource efficient & very versatile
Firefox was first developed as a quicker, safer substitute for the widely used browsers of the late 1990s, such as Microsoft Internet Explorer.
It seemed to have slipped down the food chain over time, but it has since evolved and is now highly regarded for its privacy and performance.
Regarding resource efficiency, Firefox is clearly superior to Chrome since it uses less memory and is less taxing on your computer’s operating system. Additionally, very little information about you is gathered on the browser.
You can perform address bar searches, access bookmarks, collect smart search recommendations and history, and do lots more using Firefox.
Additionally, you may customize the settings of the search bar to have greater control over your surfing process and automatically suggest URLs.Lastly, Firefox syncs all your devices, is accessible in over 90 languages, and works with Google applications like Gmail and Docs.
Other great features:
- Privacy-oriented
- Customizable interface
- Available on all desktop and mobile platforms
- Built by non-profit organization
Microsoft Edge – The default option on Windows
If you’re using Windows 10 or 11, then you’re probably familiar with Microsoft Edge. The browser uses Chromium engine, so it’s relatively lightweight.
Since it’s built on Chromium, Edge can also support all Chrome extensions out of the box. In addition, the browser has a startup boost that will help it start faster.
There’s even a sleeping tabs feature that will put tabs that aren’t currently used to sleep in order to preserve your resources.
The browser also has useful security features, including integration with Windows Defender integration, Password Monitor, Kids Mode, and more.
Overall, if you need a reliable browser, and don’t feel like downloading a new one, give Microsoft Edge a try.
Other great features:
- Built on Chromium
- Works with Chrome extensions
- Startup boost feature for faster launching
- Tab sleeping for inactive tabs
