User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 2016021000 Steps to reproduce: Whenever typing in a url in a new tab and hitting enter, it switches to the old tab instead of simply going to that website. According to the instructions, hitting shift enter should open that website in the current tab, but instead it opens it up in a new window.
Feel free to upgrade to the latest version and provide more information which exact plugins and extensions you have installed, on which operating system and version. Thanks. Cannot reproduce the problem in Firefox 45 as many other bug reports by this reporter, hence proposing to close as WORKSFORME.
It happens with the addons disabled. opensuse leap.
See comment 3 for the rest of my questions.
I don't know what else you want from me. I replicated it in safemode once, which disables addons, so that should mean that it happens with no addons enabled.
