When new version of Firefox was released, Language Pack was disabled.
Because Language Pack was not update automatically then version incompatible.
So I had to install additional Language Pack manually every Firefox update.
The installation process is simple but boring.
Therefore, I've developed this addon that I can install additional language pack easily.
You can install and update additional Language Packs from addon option page.
- Press "Open Helper Panel" button to open language install helper panel then choose language from list and install it.
- Press "Update Language Packs" button to update incompatible language packs. <-- NEW version 2.3
- Press "Open Download Site" button to open Language Pack download site then click Language Package(xpi) to install it.
You can get Language List as follows.Listing of Language Pack
In version 2.4, Firefox ESR(Extended Support Release) version
This addon do not support Firefox beta version. Because there is no way to find proper language pack(XPI data) for beta version.
