Free Software Directory:IceCat extensions (proposed)

Disclaimer: This article (including Discussion page) have merged from Trisquel web browser repository 2015-03-18. Currently about 200-300 add-ons are listed, many have been updated, removed, or replaced for following reasons: incompatibility with IceCat 31.5.0 (based on Firefox ESR 31.5.0), buggy, superseeded, bad rating, not significant popular, Service as a Software Substitute (SaaSS), and known mass surveillance services (commercial cloud/social media).

Approved

To be listed

These add-ons are not proposed, they have been approved by the FSF. However they have not been officially listed on the IceCat page yet for unknown reasons.

• HTML5 Video Everywhere!
• SpyBlock

Language packs

Language packs are add-ons that let you to have more languages available for the user interface of IceCat.

To find language packs for your version of IceCat, visit http://ftp.gnu.org/gnu/gnuzilla/, click on your version (also look in newer version of your release), then go to the langpacks directory.

Default collection

This collection includes add-ons that are part of IceCat. The collection are useful for old versions of IceCat that didn't have them installed, or Firefox users.

Also, it has been suggested in the bug-gnuzilla@gnu.org mailing list that the further versions of the default icecat installation should come without any add-ons pre-installed. This would reflect the default Firefox ESR that IceCat are forked on. For example LibreJS is still `experimental`.

This collection be compressed into a single file (say better-defaults-collection-31.5.0.xpi) with the CLEO add-on and be prompted for installation the first time a user open IceCat.
