Using Firefox (aka Iceweasel) 3.5.16 on debian stable, the browser window has recently taken to periodically freezing for perhaps half a minute or so: no update, no response to mouse/keyboard, other windows' images persist when moved over it and off again. Sometimes, after a bit clicking another app will wake it up. All a bit too much like Windows for my liking.
System Monitor shows minimal resources used, no noticeable change when a freeze happens.
Especially bad when editing Wikipedia.
Any ideas?

try it in safe mode (help / restart with add ons disabled), and see if the problem persists, if it goes away then the problem is one of your add-ons/plugins/themes/... If you've still got the problem then you know it's more fundamental.

Yeah, that does seem to have fixed it, thanks.

But now I have an insecure browser and annoying **** all over the web.

Think I'll restore them one by one, starting now.

sudo apt-get install iptraf iptop

A combination of those, statistical packet data from iptraf, and ip addresses from iptop could give you an answer. Actually you don't need iptop, but its quite useful.

Installing smartctl and running some tests would also be a good idea.

You mean FF just goes grey forever how long ?

@ nordle, nelz: thanks. When I get time to spare I'll take a look - might just use the aptitude GUI instead to install them Razz

@ RAM, FF & others freeze for varying times from a few seconds to half a minute or more. Sometimes all freeze, other times I can work in one while another clears itself. This morning I've had the first half-hour of complete normality for many days.

Is it cooler in your house today by any chance? - could be a temp issue.

hdparm -tT /dev/whatever_your_hard_drive_is_eg_sda

Once when I had a dodgy hd on a laptop, instead of seeing 30MB/sec it was down to 120k/sec Shocked

As Nelz said, smartctl will help prove if a drive is failing.

It's been a while since IPV6 caused issues, but an outside possibiity.

Try pinging your router and google.com and seeing if you lose any/many packets.

sudo ping -w 30 -f google.com

PING google.com (173.194.34.110) 56(84) bytes of data.
--- google.com ping statistics ---
2343 packets transmitted, 2342 received, 0% packet loss, time 29993ms
rtt min/avg/max/mdev = 20.773/22.672/51.441/1.198 ms, pipe 4, ipg/ewma 12.806/22.385 ms

Average 22ms is ok.

sudo ping -w 30 -f 192.168.0.1 (whatever router/modem is)

PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
--- 192.168.0.1 ping statistics ---
31240 packets transmitted, 31239 received, 0% packet loss, time 29999ms
rtt min/avg/max/mdev = 0.765/0.937/23.653/0.248 ms, pipe 3, ipg/ewma 0.960/0.927 ms

0.96ms is what you'd expect to see from a gigabit LAN.
