Firefox ShowIP add-on privacy concerns

A popular Firefox add-on appears to have started leaking private information about every website that users visit to a third-party server, including sensitive data which could identify individuals or reduce their security.

Naked Security reader Rob Sanders alerted us to the activities of the recently updated ShowIP add-on for the Firefox browser.

Currently over 170,000 people are said to be using ShowIP.

What the add-on’s description doesn’t say is that since version 1.3 (released on April 19th 2012) it has also sent – unencrypted – the full URL of sites visited using HTTPS, and sites viewed in Private Browsing mode, to a site called ip2info.org.

The user never realises that the data has been shared with a third-party, unless they use special tools to monitor what data is being sent from their computer.

Mozilla outs lethargic add-ons

by certifiedbug on April 6, 2011

in Browser

One I’d already disabled is listed in the top two, 74% slowdown. :-o

Add-ons provide many useful features and functions, but they can also cause Firefox to become slower. Some add-ons can even slow Firefox to a crawl and make it difficult to use for regular web browsing. If you think add-ons might be the reason Firefox is lethargic, check the list below for some of the biggest bottlenecks. And remember, for best performance you should disable add-ons that you no longer use regularly.

Add-ons with Slowest Start-up

The following add-ons have the most impact on how long it takes Firefox to start up.

NoScript-Adblock Plus mini wars

May 4, 2009

Content scrapers and Rogues

December 29, 2007

With more frequency I see content scrapers subscribe to security orientated blog feeds, simply to draw traffic to their own pages which link to Rogue anti-spyware programs. FeedEntryHeader is a useful WordPress plugin, allowing you to add a copyright statement with a link to the original article, at the top of your feed entries.
