openSUSE 12.2 AMD64 KDE on a Thinkpad i5 with 4Gb and another Thinkpad i7 with 4Gb
Computer connection to wireless connection (100Mb Line), in KDE LiveCD AND Gnome LiveCD mode, Firefox starts in approximately 12 -15 seconds
Disconnect the wireless connection, Firefox starts in under 2 seconds for both KDE and Gnome LiveCD.
Again, computer connection to wireless connection (100Mb Line), with openSUSE 12.2 KDE onto laptop, Firefox starts in approximately 12 -15 seconds.
Again, disconnect the wireless connection, Firefox starts in under 2 seconds for both.
On the same laptop, Firefox starts in under 3 seconds in Debian.
In openSUSE, deleted the Firefox profile and copy the Firefox profile from Debian, the same startup time of 12 -15 seconds encountered.
Is Firefox starting in 12 -15 seconds the norm in openSUSE?
Or am I the only one that encounter this problem?
It solved the problem in my case. Before changing, Firefox needed about 10 seconds to launch after clicking a shortcut. Now it takes around 2. What I did was change my /etc/hosts
#

Interesting. “Assign hostname to loopback” has been standard installation
procedure for me for many years. I always thought it was good policy and
now it seems that it may be necessary for some things.
For me, on a 11.4 openSuSE, all the applications launched by the panel are slow to launch (firefox takes about 10 to 20 seconds to launch) and sometimes I got the KLauncher message displayed…
I felt the issue since I updated the kernel and installed this ****** ATI Catalyst Control Center…
The problem is that the issue is not reproductive, sometimes the system works “as before” and sometimes it is slow that it takes on my nerves… (30 seconds to display the snapshot application, more than one minute to launch LibreOffice, …)
I checked all my hard disks for errors, the logs, no erros/warnings but this one:
(WW) fglrx: No matching Device section for instance (BusID PCI:0@0:17:0) found
(WW) fglrx: No matching Device section for instance (BusID PCI:0@0:18:0) found

in kdm.log, but that’s all. I really don’t know if I have to kill the kde or update it, kill dolphin (the champion of the slowness: more than 4 minutes sometimes to launch, fortunately not at each boot of Linux) and update it…
My KDE version is 4.6.
But I always used it and before the updates (I can’t remember all the features updated but kernel was updated and I was forced to install catalyst to work with 1920x1080 resolution).
This slowness is seriously starting to take on my nerves… it is impossible to work with Linux with these slownesses… (the only one solution was to boot on runlevel 3 but there is no IDE working in text mode ^^)

Two things:
This shows up posted to michalng’s thread. Not good, you should start
your own thread as your symptoms seem different.
Is seems to that your ATI driver installation is messed up. Do you have
radeon or other display card drivers also installed? Also try running top
or htop in a console session to see what is using the processor. I think
that 11.4 uses udev exclusively, but look for problems with udev and hald
as it appears that your display card is getting enumerated repeatedly. Do
you have all your updates for these subsystems installed?
At about the same time I noticed this thread, I also noticed FF recently seemed to take an incredibly long time to load (up to 25s or so in new KDE session). I already had the /etc/hosts loopback entry present, so nothing new to add from the advice in this thread. (In fact, I was surprised that others didn’t already have this set.)
Using openSUSE 12.2, KDE 4.8.5, Mozilla 15.0 (Mozlla repo)
I have these Add-ons:
openSUSE Firefox Extentions
User Agant Switcher
Download Helper
X-marks
It is probably using gethostbyname(), which indirectly accesses “/etc/hosts” as part of hostname lookup.
If the “noscript” addon is in use, that attempts to find all possible local names, so that it can block sneaky attempts of scripting to loop back to the local system.
