Add-ons which are installed and enabled are not visible - no Firebug icon, no Web Developer toolbar.
I was busy working with Firebug last night. This morning the icon wasn't present and I couldn't find it anywhere. In Add-on manager I disabled/reloaded then enabled/reloaded, but still nothing. Web developer toolbar was also missing and not in the toolbar menu. Checking versions, I saw I had Firebug 1.8.1, and one of the compatibility lists suggested that went with Firefox 6 (I was on 5.0.1).
I installed Firefox 6 beta, reinstalled Firebug 1.8.1, but no change. I uninstalled, reinstalled 5.0.1 and this time Firebug 1.8.0, and again nothing.
I must be missing something, but my poductivity has suffered so much that I'd be happy to discover exactly what sort of idiot I am.

The Firebug button should appear on the right-hand side of your Home button on the same bar as the URL field. It is there for me on Firefox 6 and Firebug 1.8.1.
I know where to find it. It was the absence of that icon I was complaining about. After a day and a half of doing very little, I suddenly saw that the Web Developer toolbar had reappeared (for no apparent reason). That gave me access to options which had previously been invisible, and I have succeeded in switching Firebug on again. I only wish I could tell all the other people suffering from this problem how to solve it, but the solution was quite spontaneous.
