2 persistent problems with Firefox 3 will make me change from my favourite browser

Sorry about this! 2 persistent problems with Firefox 3 make it impossible for me to go on using what was my favourite browser. Both have so many different manifestations that it won't help if I give very precise details. ALL Firefox forums report the same things, just slightly different.

1) All goes well until Firefox starts using 25-40% CPU capacity and stutters to a halt. Only solution - shut down and restart. OK if once a day - but it happens every other session now.

2) Autocomplete works fine for a time (usernames, passwords &c), then just stops. Solution - restart Firefox. So many variations on this in the usual forums - my own problem is relatively minor - at least it works to begin with. And of course I have the Google bar add-on - it's far too useful to do without.

My reason for posting this unhelpful "question" - there is almost bound to be an underlying reason for these Firefox V3 problems - too many people have reported too many similar but not identical cases. None of the proposed hacks (about:config hacks, deleting certain files &c) makes any difference.

My suggestion - concentrate on fixing these problems before making any more releases or enhancements - focus all the brilliant intellectual power of your best developers on them. It's absurd that such an amazing project should start to founder because of basic problems like these. It's almost as bad as the Windows 7 F5 problem (when your folder window isn't updated to reflect changes until you press F5).

This happened

Every time Firefox opened

== V3 was released

Hello Hugo Patten.

I am sorry you are experiencing such difficulties with Firefox. However, I do not currently know any solutions to any of your problems. However, I do know how to make it a little bit less painless.

In an event where you would need to restart your computer, don't. Instead, press Control + Alt + Delete, then select Start Task Manager. Now go to the processes tab and find firefox.exe (it may also be shown as firefox.exe *32). Then select End Process and you should be able to use Firefox again.

Create a new profile as a test to check if your current profile is causing the problems See [[Basic Troubleshooting|#Make_a_new_profile|Basic Troubleshooting:Make a new profile]]

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) See

Which security software (firewall) do you have? Some can cause the problems that you describe if not configured properly.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and themes and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.
