Around two months ago I upgraded my Firefox. I don't remember to what version (and to my surprise, when I clicked on Firefox today, it automatically upgraded to version 5, which seems to me to have the same problem), but it doesn't have an icon to stop a page from opening and when I want to go back to a previous page, there is no tab (might not have the right word) to click that will show a drop-down list of the pages I went to before, so I have to click back, back, back, until I find what I want. Previously, the back, forward, refresh, and stop icons were together on the left side. There's still a reload button (now on the right), but why no "stop"? That's very important. Plus the drop-down list of web pages visited. I also found right after I upgraded that my Yahoo mail was affected. Let's say I open an email, then click on back to return to my inbox. Instead of going one page back to the list of emails I received, it goes back to the first web page after logging in, the page where Yahoo says I have this many messages and there are updates on my friends. So I have to click on inbox again to see my list of messages. Or, still in the inbox, say I want to revisit old messages which are three pages away from the first page listing my messages, so I click "next" twice to get to them and then open one, and then click "back"---what happens is, I find myself back to the very first page instead of the third one! So I have to click "next" again! You can imagine how inconvenient it is. All of this started in the very same session when I upgraded my Firefox to the version Mozilla was promoting then. So I'd like to have my old version back, which I had no problems with. Thanks for your help.
