It would be very interesting to know who gets the $314 million every year.
During the same years that easy Google millions have been pouring in, Mozilla Foundation has become much more sloppily managed, it seems to me.
Firefox has become much less stable in the past few years when many windows and tabs are open for a long time. The most recent version crashes without activating the crash reporter. Instead of fixing the crashes, Mozilla Foundation has prevented reporting of them.
Apparently Mozilla Foundation is trying to discourage the use of the Thunderbird email client. The newest version of Thunderbird, 31.2.0, has the Save-As bug. All file saves are Save As, and suggest a different file name than name with which the email was saved before. The Save-As bug has been reported, but no new version has been released, giving the impression that the bug is deliberate.
Other obvious bugs were introduced into Thunderbird. For example, the fields for email addresses are much more difficult to read.
Pale Moon has been removing some of the issues in their FossaMail
version of Thunderbird. I haven't tested it to see if the Save-As bug is fixed.
