“You have several options if you want to save all open tabs in your browser of choice so that you can access them later.
Most browsers support session restore for instance which, when enabled, reloads all tabs open the last time you used the browser. While that works well most of the time, it can have disastrous consequences if it does not, as you may lose access to all or some of the sites.
Most web browser ship with options to save open tabs in a different way, and this guide provides you with instructions on how to do this in Internet Explorer, Firefox, Chrome, Opera and Vivaldi. All solutions are native, meaning that you don’t have to install a browser extension or extra software.” [Edited for use here]
