v4.10 messed up my firefox! Noté 4 sur 5 étoiles
4.10 and 4.11 interfere with Tab Mix Plus - "Open new tabs next to current one" and "Open other tabs next to current one" not working, new (or from the links from the page) tabs always opens at the end of tab bar. Please fix it.
4.9 doesn't have this problem so I've had to revert to that.
Please try the last version 4.11: https://addons.mozilla.org/firefox/addon/fast-dial-5721/versions/
