_new from all links.
I was previously using TargetKiller for Firefox but it currently won't work with Quantum. In Chrome, I use Death To _blank. TargetKiller can be specified to remove additional target attributes but I'm fine with an extension that just works on
Descriptions of the two extensions for reference:
TargetKiller is a small extension for the Firefox web browser. The extension removes the target attribute from links on the fly. You can specify which target attributes should get removed. By default TargetKiller is removing all target attributes which equals to _blank or _new.
Death To _blank
Keeps links from opening new tabs by removing the _blank attribute
Many web page links use the "_blank" target to open in a new tab. This is usually annoying (if I wanted to open a new tab, I would have done so myself!).
Death To _blank removes the "_blank" target from links, causing them to open in the current tab. This script also catches a few other targets (such as "blank" and "_new") that developers use.
