Its only possible use is as quick "undo" after hitting the Back button. And that works only if you don't click any other link on the "back" page. What I've wanted for years is the ability to do the following: 1. Read page A.html 2. In the middle of reading, clink on a link on A.html to view page B.html 3. B is interesting, but I want to finish reading A first. Click Back to A. 4. Continuing A, I run into another link to page C.html. Click. 5. Back to finish A. ... N. Where's that page B.html I visited half an hour ago? The trouble at the step N is that the Forward button will show me only the last page I was at, not all of the pages I saw. So nowadays I usually open links in other tabs, but that leads up to a lot of clutter and a lot of tab-clicking. There must be a better solution, and there is: N+1: Click the Forward down-arrow and choose the desired page from the menu. In the scenario I described, the Forward down-arrow would contain a simple list of pages visited directly from the current page. The same menu today contains a list of the last "chain" of pages visited from the current page. The ideal form of the menu should present a tree of all pages visited from the current page. Here's a more complex scenario to illustrate this: 1. Read page A. 2. Follow a link from A to page B. 3. Follow a link from B to page C. 4. Back twice to A. 5. Follow a link from A to D. 6. Follow a link from D to E. 7. Back to D. 6. Follow a link from D to F. 8. Back twice to A. At this point, here's what the current Forward menu contains: D F Here's what the "forward tree" menu should look like: D F E B C If the traditional Forward menu contains a total of N pages, those same pages should be the first N items of the proposed Forward menu, except every item would be slighly indented from the previous one. I hope that takes care of backward compatibility. The remaining items in the tree represent the pages that were visited before from the current page, and backed out of. By the way, I believe this kind of tree organization (visited-from hierarchy) might be a better fit for the History panel than the current FireFox flat list of pages or the Mozilla suite's site/page two-level hierarchy. Most people don't care what site they're looking at, they see pages instead. Reproducible: Always Steps to Reproduce:
