FoxyProxy Plus: possible end-of-life in November 2017

FoxyProxy Plus on Firefox

Note: Don’t confuse FoxyProxy Plus with FoxyProxy Standard and FoxyProxy Basic! Support for Standard and Basic aren’t going away!

FoxyProxy Plus, a Firefox extension that we started selling on April 22, 2009 and our only closed-source product for many years, is likely going away. Although we’ve been updating FoxyProxy Plus over the years to stay compatible with Firefox, we stopped selling it some years ago, so this should not affect any but the most die-hard of fans. You can see our current page for it isn’t complete and doesn’t allow you to purchase it.

Mozilla announced in February 2017 that support for legacy addons will be dropped when Firefox 57 is released on November 14, 2017. FoxyProxy Plus is a legacy addon. Due to technical limitations with Firefox 57 and above, it may not be possible to port FoxyProxy Plus to Firefox’s new platform. We are still researching this, but wanted to tell you now so you can prepare for the possible drop in support of this product. You’ll still be able to use FoxyProxy Plus with versions of Firefox older than 57. Mozilla will tell you not to use old versions of Firefox, however, due to security holes that are plugged in every new version.

The two features that FoxyProxy Plus adds above and beyond the other editions of FoxyProxy for Firefox are:

  • Switch proxies based on your current local (LAN) IP address, rather than the typical URL (website) address.
  • URL Training. Click a button to automatically add URL patterns for any/all URLs on a page.

Thanks to all of you who purchased licenses of FoxyProxy Plus over the years! We will update this blog when we know if we’ll be able to port FoxyProxy Plus to Firefox 57 and above.

Now offering SOCKS5 and HTTPS proxy service, free with all paid accounts!

We now offer 2 more ways for you to connect to your paid FoxyProxy account:

This is in addition to the previous ways we already offered:

  • HTTP proxy
  • PPTP VPN
  • OpenVPN

SOCKS5 Proxies

SOCKS5 is an internet protocol which sends data between you and your destination (e.g. facebook.com) using a proxy server. For users of HTTP proxy servers, this is nothing new.

So what’s different about SOCKS5? Why bother with it?

Why should I use a SOCKS5 proxy server instead of HTTP(S) proxy servers?

Using SOCKS5 is a great option if the main goal is downloading torrents/P2P or the use of other software that is not web-based like browsers… for example, uTorrent, deluge, transmission, and instant messenger software like Skype.

There are many benefits of using SOCKS proxy servers. We list some of them here:

All kinds of traffic can be accommodated

Unlike HTTP proxies which only work with webpages, SOCKS5 proxies work with any kind of traffic. This is because SOCKS5 proxy servers bundle or wrap any kind of internet traffic from any program.

Better performance with Torrents and P2P

Compared to HTTP and HTTPS proxy servers, SOCKS5 can offer faster download speeds and overall performance for smaller bits of data

[tech] SOCKS5 proxies implement full UDP, they enable users to connect to all the peers in a swarm, which results in better download speeds and overall performance.

If the SOCKS5 proxy server were to be interrupted, your P2P/torrent process would stop communicating… keeping your IP address secure.

Better performance than HTTP Proxies

The performance for some HTTP proxies can suffer because the proxy server rewrites data packet headers. SOCKS5 proxy servers do not rewrite data packet headers, so there is less overhead and faster connection times.

Reliable and efficient connections

SOCKS5 proxy servers use both TCP and UDP protocols . TCP is an internet protocol that forms a connection between a client and a server, making sure that all the packets arrive from one side to the other. It requires fitting the content into a fixed format so that it can be transferred easily.

UDP is an internet protocol that does not focus on whether all packets from a client or a server reach to the other side and in the same order. Therefore, UDP is more efficient than TCP in that it does not waste time in converting the data packets into a proper stream or fixed packets that are sent upon establishing a connection. A combination of these two means that a user is guaranteed a reliable and efficient performance from his internet connection. This is what your normal internet connection gives your — and what SOCKS5 proxy servers give you, but not an HTTP or HTTPS proxy server.

HTTPS proxies

You already get HTTP proxy servers with you paid FoxyProxy account. So what is an HTTPS proxy?

Security

When you use an HTTP proxy server, the data sent between you and the proxy server is unencrypted…even if you visit a website like https://facebook.com. The data between the proxy server and the https://facebook.com IS encrypted… but not the data between you and the proxy server.proxyserver

HTTPS proxy servers encrypt the data between you and the proxy server: 1.1.1.1 and 2.2.2.2 in the diagram. The data between 2.2.2.2 and the destination website is encrypted when the browser bar shows https:// or has a green padlock. So, using an HTTPS proxy server is more secure than using an HTTP proxy server.

How to use it?

Unfortunately, support for HTTPS proxy servers with authentication is limited in web browsers today. It’s quite complicated to configure them. But we’re working on step-by-step instructions for those who google the process and can’t follow along with the instructions that are already out there. The key point here is that authentication is required in the browser so that you can enter a username/password to access your paid FoxyProxy account.
