when i click on a bookmark, it will not open in a new tab

Hello, My understanding is that the default action for left clicking a bookmark is to open in the current tab. If you want to open in a new tab, the middle click button is usually the way to do it. ------------ Alternatively, you can install the following extension which will force all bookmarks to open in a new tab: * https://addons.mozilla.org/en-US/firefox/addon/open-bookmarks-in-new-tab/ Or this extension which will provide more options for tabs (including what you want): * https://addons.mozilla.org/en-US/firefox/addon/tab-mix-plus/
