Extension Options Menu 1.21 does it! Rated 5 out of 5 stars
Thanks for the update. I'm rather talkative about this add-on because having quick access to a list of add-ons has always been for me essential. So essential that I take this opportunity to propose that all add-ons be listed, not only those carrying out options (with for instance a mark (an asterisk or so) for those without options. The idea is, besides having all at view, to have version numbers of all as well. In older Firefox (2-3x) there was a comparable add-on that did this and it was quite handy. Anyway thanks for "Extension Options Menu" which is really appreciated.Léirmheas ar leagan níos sine den bhreiseán seo (1.20.1-signed).

Version 1.22 (not reviewed yet, but available if you click on 'version information' and version 1.21 link) has a hidden option to show all extensions. Go to about:config and set 'extensions.ExtensionOptionsMenu.ShowAll' to true. To see version numbers go to the regular options dialog for Extension Options Menu and select it there.
