My back button is not working. How do I fix this?

Question

I used to be able to go forward or backward using the arrow buttons on top of the page. I have made no changes on Fire Fox except to download the current version. How can I fix this?

Answer 1

I guess that means you updated from 3.6.* because Firefox 4 through 7 are are the same see item #4 and item #5 in
You can make '''Firefox 7.0.1''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6)]. ''Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.''

Back/Forward Home don't work in 7.0.1 due to '''network.http.max-connection'''s being upped to 256, reduce back down to 32.

Back button problems -- right-click on tab for tab history, or hold a couple of seconds for tab history, or install an extension
