Updated to version 3.2 (2012-03-21) of Ayaspell, with a better-compressed dictionary.
New upstream version 3 is now available, with expanded dictionary. Thanks to Taha Zerrouki.
Added <em:unpack> tag, required for some odd reason by Firefox 4.
This version is much much lighter, but it requires hunspell so it can work only with new firefox or thunderbird. According to Arabic speakers (not me) it is as complete and more exact than the previous Buckwalter-based version.
