Rated 4 out of 5 stars

I can't find the language packs for Firefox 4.0.1. Is it only me, or is Firefox really getting worse with each version (after the last 2.x)? The "get more language packs" link on the QLS 1.7.5 options page also does not work.
The extension is brilliant, but without language packs it's only two thirds of the expected fun (dictionaries and language preferences still work, and for Thunderbird everything works).

This review is for a previous version of the add-on (1.7.5).

While I love the idea of this add-on and keep it up to date I usually deactivate it since about FF 2.0.0.9: Changing tabs with QLS active can take several seconds.

This review is for a previous version of the add-on (1.6.5.6).
