There are just so many people complaining about Firefox 4 - all with the same basic problem - Firefox 4 consumes far-too much memory and appears to increase memory usage over time.
So far I have heard NOTHING from Mozilla regarding this problem.
Have Mozilla identified the problem? Is there a work around? When will there be a permanent fix?
The problem is likely, in my opinion, to relate to specific websites and or specific extensions. You will need to narrow down what causes a particular problem, for instance: try in firefox safe mode, with only any essential extension in use. Try to work our what sites the problem is seen on. ( A long shot but also try to see if the problem is only whilst the firefox 4 html5 parser is enabled. )
So to answer your question, I personally have not seen any indication of a general problems
Remember with millions of Firefox users, some are always going to have problems and even if only 1 in a thousand users have problems there are still thousands of people having a problem, but millions who do not.
Well, I think if you perform a simply Google search with the relevant key words you'll find plenty of people with the problem: all disabling Add-ons all disabling Hardware Acceleration all experiencing problems with many different websites all having a problem with Firefox 4's excessive, and continually climbing, memory/CPU usage and, most importantly, all NOT having a particular problem with Firefox 3.6.16
I don't need to chop a change my configuration/usage in Firefox 4 - it is Firefox 4 which is badly set up, not me.
I, and many others, want more constructive answers from Mozilla.
I am sorry if my answer is not helping with your particular problem. ( I personally do not notice problems, of high memory use when I use Firefox4, and I am certain many others have no problem. )
This is a support site, it will help you with individual problems, but even attempting to do that will often require anyone with a problem to take certain troubleshooting steps to determine what exactly the problem is.
If you see a problem with Firefox overall a bug needs to be filed and the developers will look at it. Obviously Firefox 4 will have been rigorously tested, over a million users taking part in its Beta trials. Thousands may have problems, that does not mean Firefox 4 itself is at fault, only that Millions of users use Firefox, and some of those will inevitably have a problem.
There are probably thousands that use Firefox and whose favourite colour is pink, if you post that Firefox does not work and your favourite colour is pink you would inevitably getting someone agreeing with you. (And if any such correlation proves anything, possibly it would lead to the discovery that some theme customising Firefox to look pink is problematic. Normally it is just the Maths, with millions of users all sorts of correlations can be found, but do not necessarily demonstrate causality)
Another example I often give is that breathing must be bad for you.
The more breathes you have taken, the higher your likelihood that you will have died or will do so in the near future. Until suspended animation becomes a routine reality, stopping breathing entirely is normally not a good idea for prolonging healthy human life.
Firefox is highly customisable, it is likely it is some of those customisations that contribute to problems. Firefox is also available on different platforms, that adds another layer of complexity when looking to identify problems.
Oh for crying out loud...what, are you taking lessons from Microsoft Tech Support? "There's nothing wrong with our product, the problem must be with THEM, their stuff isn't compatible with us. Or you're just using it wrong."
SHUT UP, JOHN. You're doing spin control and you know it. Firefox users have been complaining about this for YEARS, and the number of complaints keeps going up with each update. The problem is getting worse, not better, and it's obviously because Mozilla just doesn't care...because it couldn't possibly be this hard to really fix it if they actually applied themselves.
It was a HUGE mistake for me to allow Firefox to install version 4 on my machine, the hanging and crashing was nearly instanteous. The install was at 9:30 this morning, it's now barely before noon, and I've already had to force a shutdown three times already. This product is completely unusable.
I've had it. I can't stand this any more. The only reason I didn't quit using Firefox a year ago is that Chrome doesn't quite work right with the proprietary website I have to use at work. I can't stand the way the interface looks on Explorer, BUT AT LEAST THE FERSHLUGGENER THING WORKS. Mozilla has done the impossible: they've pushed an ex-Microsoft user back to Microsoft. Congratulations!
I am not doing spin control, just explaining, as another ordinary user my opinion
Man, are you blinkered! Are you receiving these messages on your planet? Have a look here:
There is a MASSIVE problem with FF 4 which has absolutely nothing to do with everything you listed.
If those are your answers, I'd rather you didn't 'help'.
It appears you do not wish to have any help,
and do not wish to try to show what does and does not work or cause memory problems. If you just wish to provide feedback one of the other sites may be more appropriate eg http://input.mozilla.com/en-US/feedback
If firefox 4 is the problem why not just revert to firefox 3.6. ?
There will be unresolved or undiscovered issues, but they will not be resolved or discovered without suitable information.
The first 2-3 weeks after I began using Firefox 4 it worked fine, but for the past several weeks (late April onward) whenever I come back to my PC after an hour or so it either displays a blank window and is using close to 2 MB or memory, or has crashed. This happens multiple times per day.
Sorry you are having problems. More info would help and it is probably best to start a new thread with specific details about your problem and your setup.
