I've remained a ff user inspite of it becoming slower and using more memory because of reliance of a number of add-ons. Quantum is a disastrous evolutionary step. Almost all of my favoured add-ons were rendered unusable. Quantum memory management with terrible - once started it just continues to eat memory until my machine grinds to a halt - I wrote software for 20 years - C/assembler/RTOS/C++/OCCAM and a host of other languages/tools - is this just down to problems with allocation and freeing of memory (memory leaks)? Do the developers not run memory tests or build development versions with embedded logging to trace these problems down? The decisions to stop users from navigating immediately to a homepage of their own choice when opening a new tab is indefensible - the add-ons to circumvent this are very slow as is loading the the intermediate page showing recent tabs etc - that just adds extra clicks and delays the process of opening anew tab - it's a dire decision - performance is terrible. I can't find a way to check *before I update FF* which add-ons will be obsoleted - this should be built in as preliminary step when looking at updating - I am angry about Quantum as it stands and on the point of deciding to use Chrome full-time - I am using it more than ever now in spite of not really taking to it. There is a lot of criticism of Quantum and no obvious statement about whether MZ has any intention of trying to address these complaints in a timely manner - to me it looks like the death knell for FF.
