Public bug reported: After updating to Firefox 18 the Arabic l10n is lost and English UI is used instead. After checking I found it was caused by presence of empty lines on top of the install.rdf file of the Arabic xpi. After manually editing the file and removing the empty line, Arabic l10n is back again.
This have been reported upstream as well, but I think it deserves a fix in Ubuntu until it is fixed there. https://bugzilla.mozilla.org/show_bug.cgi?id=828151 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: firefox-locale-ar 18.0+build1-0ubuntu0.12.04.3 ProcVersionSignature: Ubuntu 3.2.0-34.53-generic-pae 3.2.33 Uname: Linux 3.2.0-34-generic-pae i686 AddonCompatCheckDisabled: False AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
