Package: iceweasel Version: 44.0+ That version has cookie confirmation dialogs removed, cookie settings are then changed to default to 'Accept', and fine-grained cookie permissions that were previously set, are gone, resulting in data loss after upgrading. This reduces user privacy.
Relevant upstream bug: https://bugzilla.mozilla.org/show_bug.cgi?id=606655 Data loss reported at comment #44 there, and further comments are restricted. Upstream discussion moved here: https://mail.mozilla.org/pipermail/firefox-dev/2016-February/thread.html#3890 Ditto with upstream SeaMonkey: https://bugzilla.mozilla.org/show_bug.cgi?id=1235199 Users can currently use Firefox up to 43.0.4 and 38.6.x ESR, and block future upgrades. Though, in time, these browser versions will have become outdated for the modern web of the future. I'm afraid Firefox 45 ESR, to be released in early March 2016, won't have the cookie confirmation dialogs either. Upstream does not seem to be very interested in returning the cookie confirmation dialogs, although I'd like them in future releases of both GNU IceCat, Debian Iceweasel, and another browser based on Firefox.
