The problem was detected by users from Russian forum for 52 release version. I checked and confirmed for 52 beta 3 version.

Can you provide a page where this happens? I tried http://7-zip.org/ and clicking one of the download links doesn't open a tab (Firefox 52.0.1, Windows 8.1)

This is caused by multiprocess architecture of Firefox and will be fixed in Firefox 55, see bug 1301056.
