QupZilla Portable 1.4.2 is a lightweight, modern web browser based on webkit. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Platform. And it's open source and completely free.

QupZilla Portable is packaged in a PortableApps.com Installer so it will automatically detect an existing PortableApps.com installation when your drive is plugged in. It supports upgrades by installing right over an existing copy, preserving all settings. And it's in PortableApps.com Format, so it automatically works with the PortableApps.com Platform including the Menu and Backup Utility.

QupZilla is a new and very fast QtWebKit browser. It aims to be a lightweight web browser available through all major platforms. This project has been originally started only for educational purposes. But from its start, QupZilla has grown into a feature-rich browser.

QupZilla has all standard functions you expect from a web browser. It includes bookmarks, history (both also in sidebar) and tabs. Above that, you can manage RSS feeds with an included RSS reader, block ads with a builtin AdBlock plugin, block Flash content with Click2Flash and edit the local CA Certificates database with an SSL Manager.

QupZilla's main aim is to be a very fast and very stable QtWebKit browser available to everyone. There are already a lot of QtWebKit browsers available, but they are either bound to the KDE environment (rekonq), are not actively developed or very unstable and miss important features. But there is missing a multiplatform, modern and actively developed browser. QupZilla is trying to fill this gap by providing a very stable browsing experience.

Native look'n'feel
QupZilla is using native widgets style on major Linux Desktop Environments. It is also using icons from the active desktop icon theme. If you find native themes too boring or have some problems with it, you can always switch to other themes.
Unified Library
QupZilla unifies bookmarks, history and rss reader in one well-arranged window. No more multiple windows, QupZilla uses just one!
With the integrated rss reader, you can stay up to date with your favourite sites. QupZilla can also import bookmarks from other browsers.
Integrated AdBlock
Are you bored of websites full of advertisements? Are they eating your bandwidth and time? The only thing you need with QupZilla is to update EasyList or maybe add your own rules and start browsing ad free.
Speed Dial
This popular extension is finally available for QupZilla users! You can now access your favourite pages as fast as you want on one page opened in new tab. Needless to say that it fully supports drag&drop and page thumbnail loading.
