User-Agent: Mozilla/5.0 (OS/2; U; Warp 4.5; es-ES; rv:184.108.40.206) Gecko/20081212 SeaMonkey/1.1.14 (PmW) Build Identifier: Gecko/20110611 SeaMonkey/2.1 After installing language packs to SeaMonkey 2.1, a quick peek at the error console after startup reveals several messages (exactly one per language pack installed) logged in this fashion: Could not find jar manifest entry 'chrome/<locale code>.manifest'. Tested with de, en-GB, es-ES, ja and ru so far, but I couldn't select more than one for this report. Reproducible: Always Steps to Reproduce: 1.Install a language pack to SeaMonkey. 2.Restart SeaMonkey 3.Have a look at the error console. Actual Results: I see the described errors logged to the console. Everything else seems to work without problems. Expected Results: Not to get any errors. If you get into the installed <language pack>.xpi file, there's a file called chrome.manifest inside; in all of the offending language packs it contains a line that reads "manifest chrome/es-ES.manifest" or whatever language it is, while there's no such file inside the XPI file. Removing the line makes the corresponding error not to be logged at startup, but I'm not sure whether this a fix for the problem or just for the symptom.
This may be an issue in SeaMonkey build configuration, since localizers don't prepare the manifest files themselves.

Firefox would seem to have the same issue: /pub/firefox/nightly/2012/02/2012-02-07-03-11-36-mozilla-central-l10n/win32/xpi firefox-13.0a1.be.langpack.xpi Alfredo, can you try and confirm?
Yes, of course; it's been there at least from FireFox 6 (sorry I haven't anything older installed). I planned to report it for FireFox as a duplicate of this one, but then forgot, sorry. Could you please do it?
