Firefox slower and taking up more memory

I started checking on my Firefox and it is slower than usual, in addition I noticed that it has taken up much much more memory than it usual does. Even with multiple tabs I would check it once in a while and it still didn't run at this speed with this amount of memory usage. I don't have any dl or any new programs running in the background according to my task manager. Any solutions?

 

I have foxytunes, image zoom, mileswide back, and bugmenot. Are any of these know to slow down firefox. As I mentioned firefox was running pretty quick before.

 

Try clearing your cache and turning off automatic checks for updates.

 

I did that a long time ago and nothing new is there to slow me down.

 

Do you keep Firefox open for long periods of time? A bug in the current version is memory usage increasing the longer the browser is kept open. If you minimize for 2 seconds the mem usage drops back to initial levels.

 

i know this is going to sound dumb, but i don't get what the answer is. my pc has been getting progressively slower despite my going through the whole spyware cleaning routine advised on this site. i searched "running slower" and saw firefox thread after firefox thread. i cleared all my saved info (cache, cookies etc) and shut off the auto update feature. it seems a little better but the difference is slight enuf that it could be my imagination. so i started firefox in safe mode and it came up just as slowly. so.........what's my answer? or do you only get one if firefox is quicker in safe mode?

 

Make a new profile and see what happens. Best and fastest way of troubleshooting extensions. You can have 45 installed, all is fine but with just 1 conflict anything can happen. Conflicts are quite common, to find out try search extension forum at www.mozillazine.org may be also http://www.extensionsmirror.nl/ Very important to keep them updated.

Put user_pref("config.trim_on_minimize", true); in user.js to let FF clear most memory when minimized. I guess default is false, not sure though. Wont hurt to have it in user.js http://www.mozilla.org/support/firefox/edit

You can grab latest "aviary" versions of FF here http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/sweetlou-aviary1.0.1/ might make you feel better at least 1.04 is almost identical to official, 1.05 has some modifications, see Mozillazine for details. Both what you could call "stable", not like 1.1.

 

A new profile is the right idea, but there are a couple things should be said about re-installing extensions. 1. Install one at a time, and test after each one. 2. Only install those you really use. The fewer you have, the less chance of conflicts or corruption.
