I’ve tried repeatedly to open a page in responsive design mode in the 64bit Dev Edition (v. 56.0b6) where it contains a href link with a target of ‘_blank’ - and when the link is clicked, the new window won’t open and the target is totally ignored. Regular, non-targeted links work fine in responsive mode, and they all work fine when the browser isn’t using responsive mode and opened to a desktop page layout.
Using standard FF 64bit v. 55.02, everything works as expected in either desktop or responsive mode.
I’m also having random CSS and javascript issues where some things won’t show at all… like forward/reverse arrows in lightboxes and overlays when in responsive mode in the Dev Edition.
Is anyone else experiencing the same type of things? Are there multiple issues with devtools that need some serious attention? I’m not about to jump away from using the non-dev browser if it’s the only version that’s stable enough to use.
