Fedora 26: Icecat Update RHSA-2018:0520 Security: Spectre Mitigation

GNUZilla Icecat is a fully-free fork of Mozilla Firefox ESR.

Extensions included to this version of IceCat:

* LibreJS

GNU LibreJS aims to address the JavaScript problem described in Richard

Stallman's article The JavaScript Trap.

* SpyBlock

Blocks privacy trackers while in normal browsing mode, and all third party

requests when in private browsing mode. Based on Adblock Plus.

* AboutIceCat

Adds a custom "about:icecat" homepage with links to information about the

free software and privacy features in IceCat, and check-boxes to enable

and disable the ones more prone to break websites.

* HTML5-video-everywhere

Uses the native video player to play embedded videos from different sources

* Fingerprinting countermeasures: Fingerprinting is a series of techniques

allowing to uniquely identify a browser based on specific characteristics of

that particular instance (like what fonts are available in that machine).

Unlike cookies the user cannot opt-out of being tracked this way,

so the browser has to avoid giving away that kind of hints.

- Update to 52.5.3 - Patched for mozilla bug-1427870 (spectre mitigation)

su -c 'dnf upgrade icecat' at the command line.
