Hi, just upgraded from firefox 3.6 to 4. The main problem I have with this version which will make me go back to 3.6 if I can't solve it, is that in this version (4) there is no back history to click on next to the navigational back and forward buttons. I'm not talking about the history menu from the menu bar. I'm talking about the pathway I took to get to the page I'm on, which will be different for every tab that I have open. Sometimes if I've just gone through ebay or paypal checkouts or sent/posted questions on forums etc, I will not be able to just repeatedly press 'back' as it may resend twice, or force me to resend data to re-enter that page, even though I didn't want that page, I wanted the page that was 5 steps back prior. You know what I mean? It used to be great to use that on 3.6 to navigate around and jump about back and fore 8 or 9 pages at a time. The history button in the menu bar doesn't help me, it just tells me the last few pages I've been to overall, and not specific to that tab. Also, how can I customise the navigation bar? I want an icon for the refresh button back like the one in 3.6 (big, prominent, and moveable). Same for the home button, it's now stuck at the far side (I used to customise all these buttons to be as together or as central as I could).
