How to set multiple Homepages in Firefox
For all Firefox lovers, here is one simple trick I found regarding tab browsing. It enables you to do one cool thing and that is have more than one homepage.
To do so, simply open up the pages you want as homepages and put them into separate tabs.
When go to Tools > Options and click on the General button.
For homepage, you will see a button that says “Use Current Page(s)” (notice the plural).
Hit that button and you have just recorded all of those pages as your homepages.
Now whenever you click the Home button, all of those sites will load up.
