Free Software Directory:IceCat extensions (proposed)

From Free Software Directory
Jump to: navigation, search


Proposed GNUzilla IceCat (the GNU version of Mozilla Firefox) add-ons. This page is to help organize our work of reviewing and properly identifying the licensing info on thousands of add-ons listed on the Mozilla Addons site. The reason this work is necessary is because of numerous errors the licensing information provided on addon pages, including proprietary programs listed on the Mozilla site.

Urgent

Please help us setting up these add-ons, see Discussion for details:

About

Currently about 600 stable and essential add-ons are listed. They have been tested with the latest icecat package in Trisquel, lagged from the release date with a few weeks in general. They will be continued to be tested in Trisquel as the IceCat maintainer, Rubén Rodríguez, also is the project leader of Trisquel.

  • See this page for a list of add-ons from this page that have been primarily reviewed and are likely to be officially approved. If you see "Not available for Firefox 31.0" for an add-on in addons.mozilla.org you have to go to the add-on page and click on "Version Information" and then on "See complete version history" to find a version that match your browser version. See FSD:IceCat add-on third-party repositories for tools for the add-ons in this page.

Merged repositories to this one:

The section +1 M Daily Users have been merged to the Trisquel Web Browser repository.

Many add-ons are present in all repositories so its hard to say exactly how many add-ons that have been reviewed. Many add-ons not found in any of the above repositories have been added here. Also note that the repository on this page has superseeded the these repositories for the following reasons: Many add-ons have been added that is not found in these repositories as add-ons here have been updated, removed, replaced for following reasons: incompatibility with IceCat 31.5.0 (based on Firefox ESR 31.5.0), buggy, superseeded, bad rating, not significant popular, add-ons for proprietary software or formats (Microsoft .NET Framework Assistant, and softwares with Flash, MP3, MP4, etc in the software name), Service as a Software Substitute (SaaSS), support for other OS but GNU/Linux (general Free Software Directory requirement), secure version over non-secure version (SSL versions of OpenSearch over non-SSL versions), international version over national version (eg meteorology add-ons), and known mass surveillance services (commercial cloud/social media). The reason why you don't find these add-ons on the IceCat page is because they are not published on the Free Software Directory.

Add-ons that were listed on addons.mozilla.org without any license were manually downloaded and reviewed. I added them only if the files distributed them as free software.

Additional resources

  • 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.

Development


Disclaimer

  • Please add "IceCat" but not "Firefox" in the "This an extension, add-on, or plugin to" field in new add-on entrys, as suggested by the FSF.
  • Please refer to addons.mozilla.org pages if you cannot find any license in the source. Sometimes they add it just on the project page in addons.mozilla.org.
  • Please verify license for unapproved add-ons before adding new ones.
  • If you switch from SpyBlock to uBlock. SpyBlock subscribes to all filters in http://gnuzilla.gnu.org/filters/ (note the non-SSL connection). All of them except javascript.txt are enabled by default. uBlock can subscribe to Adblock Plus filters too, if anyone just could provide subscription links to them (not possible here in directory.fsf.org). I have asked the owner of https://adblockplus.org/en/subscriptions to add them there but note that http://gnuzilla.gnu.org/filters/javascript.txt and http://gnuzilla.gnu.org/filters/third-party.txt cannot be added because ABP doesn't support that "when in private browsing mode" feature, according to him.

NoScript Security Suite
Allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks. Review notes: Useful to use Flash, Java, and video plugins securely. NoScript implements two features not found in uBlock: Application Boundaries Enforcer (ABE) and ClearClick (anti-clickjacking) to protect web browser plugins from being exploited. However, in most cases plugins are unnecessary in web browsers, and security experts recommend that it not be run in a browser unless absolutely necessary. If plugins are required by a few web sites, users should have a separate browser profile specifically for those sites. Note that frame-based clickjacking is still possible even if you don't use plugins, NoScript can prevent this but also give false positive notifications. µBlock or Adblock Plus based add-ons provides great power & flexibility in controlling cross-site requests, but requires writing rules. NoScript that blocks all scripts (or RequestPolicy for cross-site requests) provides an interface that is quick & easy to use, and perhaps most importantly, gives feedback about which requests are being blocked/allowed on each page, but without the fine-grained permissions that the other mentioned add-ons allows.

NoRedirect
NoRedirect lets the user take control of HTTP redirects. Review notes: This is a useful add-on as neither of these browser settings protects against sophisticated popups: Preferences -> Content -> Block pop-up windows [enabled by default] and Preferences -> Advanced -> General -> Warn me when websites try to redirect or reload the page [enabled by default]. This add-on can be used to do that. Blocking redirects are useful to debug redirect based popups but requires specificed domains. RequestPolicy 0.5.28 asks if both popups and redirects should be visited (a feature that has been withdrawn in RequestPolicy Continued starting with version 1.0). However, RequestPolicy is run before uBlock.
