I just installed Firefox 4, and the back and forward buttons are greyed out. Also I am no longer able to refresh a page.

After recently installing Firefox 4, the back and forward buttons appear to be greyed out (clicking them is not an option, when I go to a new page it's as if I opened a new one.) I also cannot refresh any pages.

This can be a problem with the file places.sqlite that stores the bookmarks and the history.

I just followed those instructions (deleting the "places.sqlite" file from the profiles folder, but still, nothing!

Any other ideas?

I had that problem. If you're running McAfee SiteAdvisor, disable it and restart Firefox.

McAfee is working on a fix, according to their support forum.

I'm not running McAfee... Here is all my troubleshooting info:
