[Mozilla Enterprise] Preventing Firefox from downloading langpacks ?

[James Pearson]

We're just using the Mozilla provided tar archive - so there is no distribution directory in that package ...

We're going to see if we can reproduce the issue and attempt to 'see' where they are coming from

What package are you using? Based on the fact that pref is fixing things, it sounds like the language packs are in the distribution directory of the Firefox package you are using.

That's where they are being installed from.

We're running ESR 60 (Mozilla build) on Linux (CentOS 7)

I did find the following:

 https://access.redhat.com/discussions/3509781#comment-1322671

which is about the RedHat/CentOS rebuild of  ESR 60 copying in langpacks - however, this build does bundle a number of langpacks as part of the installed package

However, we are not using the RedHat/CentOS package - and don't have the langpacks installed anywhere, however, users are getting langpacks in their Firefox profiles ...

The workaround suggested in the above link is to set 'extensions.installDistroAddons' to 'false' - which appears to fix the problem for us

I'll do some some more poking about to see if I can find out 'how' these langpacks are being installed in user profile directories

We don't download language package in Firefox 60. We do in 68 if a user selects a new language.

If a language pack is already installed via some mechanism, we might grab an update for that language pack and put it in the profile.

Can you provide more details on what you are seeing?

Most of our users don't have access to the Internet, but for users that do, we've noticed that ESR 60 appears to download a set of langpacks to their Firefox profile - the total size of all these langpacks is 'only' about 65Mb, but it does eat into the rather meagre home directory quota we have ...

Is there any way to turn off these downloads - and use (single copies of) centrally installed langpacks instead ?

I'm not aware of this happening with ESR 52 (and earlier)

Thanks
