• 29.0.1 Firefox won't open links that require a new tab to be opened.

  29.0.1 Firefox won't open links that require a new tab to be opened.

  What type of links are those?

  As far as I KNOW, there is HTML code specific opening in a new tab, as it is to open a new window. Please enlighten me if this is something new to HTML5 that I haven't read.

  Now, Firefox has a preference in Options > tabs to open new windows in a new tab instead - you have this pref checked?

  MSE says that I have to run Defender in order to remove found threats.  I can't launch the Defender, it keeps closing

  Suppose MSE wants that you run Windows Defender in offline mode (RDO), which is not the same as the defender of Windows that is installed on Win 7 and is disabled when MSE (and other anti-malware programs are installed.  Yes, it's very confusing.

  In any case, see below for information about the RDO:
