Firefox users have several options if they want to open multiple links in the web browser at once. They can click on each link individually, or use a popular extension like Snap Links to open them all together.
But there is no real option to open multiple websites from a text document for instance, other than copying and pasting them into the browser one by one, or clicking on them individually to launch them in the browser.
The Firefox add-on Open Multiple Locations offers a solution. It enables you to paste a set of urls into a form to open all websites in it at once in the browser.
The add-on adds a new entry to the Firefox File menu that is called Open Multiple Locations. A tap on the Alt-key and the selection of the entry in the File menu opens a new window in the browser with a text area.
Text can be pasted into that area from the clipboard or entered manually. The extension supports two different types of data: First, a list of urls that can be separated by spaces, commas or line breaks.
The second mode goes a step further.You can paste text into the form that includes website addresses. Open Multiple Locations parses the text and opens all urls found in it automatically.
You need to tell the program about the type that you pasted or entered into the form.
Open Multiple Locations is a straightforward add-on for users who sometimes have to open url lists stored outside the browser. The option to extract urls from a text document is very powerful for users who work with documents containing urls.
Update: The most recent version of the add-on ships with another useful setting. You can delay the opening of links to avoid overload in the browser. Just enter n seconds and the add-on will wait the selected time before it opens the next address in the browser.
