Mozilla Firefox comes with a handy feature of simply dragging any website onto the bookmarks toolbar due to which the bookmarked website will be one click away from being accessed.
To do this, first make sure that the bookmarks toolbar is enabled by going to View > Toolbars > Bookmarks Toolbar.
Once done, simply drag any open website to this bookmarks toolbar so that it will show up with the related icon.
Now simply click that website to launch it as and when needed. It gets better too if you have many bookmarked websites placed on the bookmarks toolbar. Right click the toolbar and select “Open All in Tabs”.
This will launch all the bookmarked websites present on the bookmarks toolbar in different tabs.
