Portable Proxomitron

Portable Proxomitron is a local HTTP web filtering proxy program that selects and notifies users about intercepting requests from webpages and servers before the browser sees them. This helps you monitor everything that goes in and out of your browser.
This is the portable version of the desktop-based Proxomitron, which means that users can carry it around on USB flash drives and open it on any computer available.

Colorful and useful interface

Portable Proxomitron's interface is extremely colorful. It is small and holds a couple of tick boxes which mostly limit some basic items that automatically play in your browser, like GIFs, incoming and outcoming headers, and so on.
Except that, users can manually edit features for a target webpage, manually connect to HTTP proxies, and access a configuration segment where more advanced options for the tool are available.

Powerful web filtering features

Despite the 'cheap' look of the program, its functionality is pretty thorough. Users can set it to stop popup JavaScript message boxes, freeze GIFs, and disable window popups and banner chains. Basically it acts as an advanced ad blocker.
However, Portable Proxomitron also allows access to different IP addresses besides the host PC. All users have to do is introduce the target IP and the utility starts working from there.
When it comes to configuration settings, there isn't much the app can do except the basic web data filtering. This lack of extra options in the tool's list of features might be limiting to some, but it can be extremely useful to most users who can't really handle lots of complex settings.
Users can change the basic visuals, but only if they introduce textures in BMP format. Additionally, they can set the tool to run when a certain program starts or a certain URL address has been introduced. In case the application becomes too intrusive, they can set it to run in the system tray only.

Conclusion

Proxomitron is a powerful web filtering proxy that mostly runs as an advanced ad blocker for annoying ads, webpage popups, and other annoying Internet HTML or Java-based advertisements. Obviously, users can filter data access to and from their browsers, and stop blocking features that may come in their way.
