reload button just reload the current tab
back button - Go back one page (in current tab)
forward button - Go forward one page (in current tab)
how exactly you open new tabs ?
My problem is that some sites do not allow middle-click to open new tabs, must be Flash content.
So, I have to open a new tab with the previous page, and continue the arduous task of doing this over and over(This is a side-story. Most of the time, I want to open the previous page repeatedly for many other options I forgot in that page.). I press the forward button when I have some re-purpose and I would like to have the content again without having to press forward(In current tab).
Pressing the reload button is to make a new tab with the same page, in case I have something important in that current tab but I have another task I want to perform. (It is much more easier to middle-click the Reload button and obtain a new tab with the same content, or having to click the URL and press Alt+Enter, I prefer the middle-click option, keeps me from using the keyboard.)
Like, if I forget to sign in on my YouTube account to like/comment a video, I open a new tab to do so or I have to re-download the video again to see it, in which it can become very annoying.
Also, the Add-ons in the Options Menu does the same thing.
