Random sites each day
Every time we start the browser, it greets us with an empty tab. Choosing which sites to open may require mental effort that we could have used for something else. Opening n tabs and typing that many URL addresses can take some time. But if we know what sites we frequently return to, we could write a small script and then access it through a bookmark in the browser. This could open only the sites we want or only a fixed number from a list for each day of the week. Each list may have some theme: for instance, on Monday we may choose to open sites about ideas, creativity and innovation; on Tuesday we may want sites about marketing; on Wednesday about web design and so on. We can freely customize all these themes based on the bookmarks that we have already collected. This way we can open as many sites we want at once.
But this is also problematic for a variety of reasons. Opening so many sites can be seen as an automated script attack to steal traffic or to bring a service down. This happens often in uncontrolled environments, where there is no limit on the number of requests possible. For this reason, browsers often restrict the opening of tabs and they treat them as popups that are then blocked. The browser gives us only different options how to deal with them. But on our local machine, we know what will get opened and when. We carry the full responsibility for our actions, so we can enable them only for that particular domain. Another problem with opening many tabs is that this may require a lot of resources. Each website may use tens of megabytes of memory, so we need to know in advance whether our machine could meet the demand under normal circumstances. Once we open too many sites, switching between them will become much harder.
In this very simple demo I have chosen to open only two websites just to illustrate the fact that any number can be opened at once. You can copy the script and make your own adjustments to fit the way you tend to browse. Once you open the file in the browser, you can drag it to your bookmarks and use it many times. Or you may choose to have a single small list of sites with no randomization. In each case it may be a good starting point.
