The easier way is of course to use the built-in method in reopening closed tabs either through a hotkey or from a few mouse clicks. One way to reopen the closed website is by checking the history where you can find a list of all the visited websites pulled from the local database. A frustrated user may continuously press the CTRL+W hotkey multiple times in attempting to close a few tabs hoping to reduce the memory usage but they can end up accidentally closing the important tabs that they want to read at a later time.
When the amount of tabs increases, so is the memory usage of the web browser and sometimes it can cause the web browser to hang or crawl. It is common for some people to have a lot of tabs opened because of constantly opening new hyperlinks from the webpages in a new tab but does not close the previous ones. Thanks to the tab features implemented on most if not all web browsers, we are able to open multiple websites from one program window without the confusion of switching between running programs and opened webpages.
