Hi there. After Firefox 44.0 was released, it turned out, that it lost the cookie confirmation dialog, and upgrading to version 44.0 also deleted all per-site permissions for cookies. It's a reduction of privacy options, and also introduces some dataloss.
All this was achieved in Mozilla Bug 606655 https://bugzilla.mozilla.org/show_bug.cgi?id=606655 Dataloss reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=606655#c44 After Firefox 44.0 release, many ferociously complained in Bugzilla, and the bug was thereafter restricted to any new comments; any relevant discussion was moved here: https://mail.mozilla.org/pipermail/firefox-dev/2016-February/thread.html#3890 Note, that SeaMonkey also experienced the same backend/UI loss: https://bugzilla.mozilla.org/show_bug.cgi?id=1235199 For the time being, people can stay with Firefox 43.0.4 or Firefox 38.6.x ESR. There is, though, a strong possibility, that Firefox 45 ESR (based on Firefox 45, planned to be released on March 8) won't have the cookie confirmation functionality anymore. I was thinking, that cookie confirmation dialogs should be retained in IceCat, given that IceCat is much more privacy-conscious. -M. -- http://gnuzilla.gnu.org
