Some Firefox users reported noticing  “wyciwyg” link while surfing the Web. In some cases, their browsing session is not interrupted, but instead or along with “http:” indicator, they get the latter phrase added to their URLs. Alternatively, some users have experienced a more aggravating issue as the link redirects them to a blank page:

For the past couple of days Firefox always redirects to a blank page when I try to visit any page on When I use IE tab on the blank page it comes up with the url “wyciwyg://#/” where # is a number that changes occasionally.[3]

There are two explanations for such phenomenon. Firstly, the wyciwyg link is the result of the Adblock extension bug. Updating the extension to the latest edition or disabling and then enabling again might be helpful. Secondly, if besides the link, additional new tabs promoting gaming and gambling sites, then scan the browser or reset it to get rid of adware and other forms of browser infections.
