Comment 236 for bug 93546

Mike S - Not disagreeing a bit. There are also other significant flaws in FF4 and up (dysfunctional default UI, rapid release cycle, the 'fix' for bug 586234, inability to clone a tab).
I don't think it is necessarily a reflection on all software developers, not even on all who work on FF. My guess is - and that is true for commercial software as well - some folks with a far too big ego make the decisions and they want things to be their way. The UI change that nobody wanted - still there. The rapid releases that still break add-ons and that caused hundred thousands of complaints - still there. All the stuff that works fine in FF3.x and was broken for no reason in FF4 - still there. I think that up until FF3 Mozilla was close to the community of users and made a browser that users loved. Then something changed, a decision was made to copy Chrome and entirely ignore the wishes of the user community. What Mozilla needs to do is replace the decision makers with folks that care about the users more than themselves. FF turned into the materialized ego trip of a select few and the result is unhappy users and continuously dropping market share. I really wonder how the decisions are made which bugs to fix first after covering security issues. My guess is that new (and buggy) features trumps fixing bugs filed a decade ago. And the memory leaks are still there, but that is a common occurrence in FF since version 1.

As far as sharing a profile is concerned, I think that it is even more a need for Thunderbird. You wrote that you are a developer. I know it is a common response that gets used too often, but maybe you can take on this issue and fix it? I wish I could, but I am just a QA buff and a regular user aka someone who the FF folks give a damn about.
