Firefox slow down

I've been using firefox for a while now and recently I've been getting a pop up from my AVG saying firefox is using too much memory and it suggests shutting down and restarting.
Up to now I've not noticed a problem, but I recently downloaded Firefox 12, I think it was.
Anyway, since then I'm just getting almost zero movement on pages after I open a few tabs on Firefox.
I've gone back to using IE, which appears to be OK at the moment.

Any ideas as to what is going on?
Its got me stumped.
But then that dont take much when it comes to PCs
Thanks

 

Hi Pete. As my main browser I use FF12 too and also have IE available. I've just used Windows task manager (Ctrl + Alt + Del ) to look at the memory demands of the two browsers. FF comes out on my PC as using 109,052kb and IE as 121,012 so FF is using less than IE.
It would be worth you having a look at the processing demands of your version of FF via Task manager. If you've installed many of the FF add-ins it may be that your FF browser is a bit bloated for the capabilities of your PC. Beyond this I'm stumped!

(I'm running XP on a PC with a 3GHz processor and 2GB RAM)

 

Thanks Dave I will endeavour to check this out. lol

 

AVG might be the culprit. I haven't used it for a while so things might have changed but AVG used to maintain an ever growing log file, and then once that log got too big AVG would start randomly blaming things for being bad.

Don't turn off AVG, but if you can find its log file and zap it and see what happens.

 

Ok clueless I'll have a go.

 

I'd thought about AVG being the culprit but dismissed it as Pete indicated that IE was working ok and AVG monitors FF and IE. I use AVG too.

 

I get that, Pete - it's AVG! I just dismiss it and carry on as normal!

 

I have been dimissing it up till now Daisees.

But since I downloaded the newest fire fox version, after opening half a dozen tabs things just grind to a halt almost.
If I shut down firefox and restart its OK.

 

Ah - perhaps I'll try that too!

 

Pete, how much memory does your PC have?
Reason I ask is that I've just had a look at FF's memory usage going from one tab open to five tabs open and the difference between one and five tabs is around 20,000k which isn't a vast amount of memory.
If you can open five or six tabs in IE without any slow down then I'd guess that the problem lies in the way FF is configured or else the way that AVG is seeing FF.
You could test if it's AVG by turning AVG off and then using FF to open tabs on five or six sites that you know are ok.

 

I've got 1.49 G of ram

But I get the scrolling being slow, and changing pages a bit slow.

 

I'm also finding firefox is not liking Yahoo mail.
It wont down load messages for me, goes through the process but nothing happens, it seems to think its done it.But no message appears.
It seems to be working on IE.
