Mozilla Browser security extensions are not the ultimate as they seem, in-fact they might even make your browsing experience worse than it should have been. Mozilla has pulled Avast’s Online Security and SafePrice extensions for Firefox, including their AVG-branded equivalents, after AdBlock Plus inventor Wladimir Palant discovered that they were collecting much more data than normal.
The data collection includes a detailed web history that is not just site address and search history, even when and how long one visits a site, what the person click, the number of tabs that was opened and how and what time the user switched to another tab. Mozilla’s policies completely forbid this kind of detailed collection.
Wladimir Palant had first written about the deep collection on October 28th, but it wasn’t until he reported the problems to Mozilla on December 2nd that he took action by pulling all four extensions within 24 hours. Next, Opera pulled the corresponding extensions on its store within 16 hours of receiving notice.
Those who like the extensions may still have them back according to Avast statement to ZDNet, which says it was working with Mozilla to clear up issues. It had “already implemented” some of Mozilla’s more recent privacy requirements, and planned versions that were “fully compliant and transparent.” You can expect them back in Mozilla’s extension anytime soon.
Another problem that’s associated with this is the fact that the extensions seems to violate Google’s policies for Chrome extensions, but were still available in the Chrome Web Store even at the time of writing this article. We’re looking forward to receiving comment from Google on this matter, for now, we could say that Chrome’s popularity could exacerbate any privacy violations.
