Dear Mozilla, As a long-time Firefox user and evangelist, it saddens me that the time has come to part ways. I have seen threads from others commenting on Firefox's aggressive memory consumption and retention. I have not measured this and thus do not feel qualified to comment, but, sadly, I am not surprised. My own experience in recent times highlights 2 events that have driven me here. 1) Several websites just not responding in that some screens will not even scroll. This is fixed by me moving to a different browser. 2) More seriously - When trying to fill in a web form for a work job application the page was completely unresponsive. When I contacted the web site support their answer was: "Are you using Firefox? Ah, Yes, we are having issues with Firefox that we are trying to resolve. Our suggestion for the time being is, if practical, try using a different browser". That answer worked. I should add that the usual cache clearing, machine restarts, even Firefox reinstall did nothing to fix either of the above issues. So with the serious memory greed issues reported by others and my own (dys)functional experiences, I fear the time has come. Thank you for the last 30 years or so and I am sorry it has come to this. Best of luck in your future endeavours. BTW - This post was entered using a different browser.
