One of the main causes of the blocking of our browser when you sail in line is the opening of several windows at a time. This action can certainly increase the download of tabs as well as the passage from one tab to another. To remedy this, I propose to you an extension to motivate them to take necessary precautions.
It is Max Tabs. A nice application that will require you to limit the number of tabs to open on your browser. It is an add-on for the Firefox browser and its principle is simple but very useful especially for those who have this habit of open several windows at a time without worrying about the speed of the browser. This extension will be programd by you in such a way as to notify you of that you have exceeded the number of tabs that you you determined in the settings.
It is a kind of alarm to ensure a good navigation and a normal speed of the browser. Once the alert is displayed you will be forced to close the tabs that you do not need prior to the opening of another.
