NEIL_M  Not for me.  
(Version 2.8.0.659)

BOSSA-NOVA  Of course not, it's not even the same version!!! My posting is weeks old! Don't reply if you use a newer version of a software.

By the way, the problem seems to be gone with this update.  
(Version 2.8.0.659)

NEIL_M  Not for Version 2.8.0.438 either.

You are a sour puss.

Ask chad@macupdate.com to delete your comment, if you think it is no longer relevant.

NEIL_M  In case you had not realised, macupdate add the version reference to the comment (which is the version of the listing, now 2.8.0659), not the commenter.

ROBOTANK  Firefox also takes a long time to start for me. I used to have too many extensions.I got rid of most of them, but I didn't notice any substantial improvement in loading time. I hate FF's long load time: It makes it feel bloated, and makes Safari feel like a far more streamlined browser.

MACFOOL  About 2 seconds to load on a Dual G5 10.5.7 and maybe 3 seconds on a new 4 GB Mini 10.5.7

Y'all got something wrong.

BOSSA-NOVA  First launch of Firefox after a RESTART of the computer?  
(Version 3.5)

BRUCEANDERSON  Part of Safari is running in the system itself, so its initial launch time is shorter. Firefox has to bootstrap itself. After the first launch after a reboot FF should start about as quickly as Safari does.

But I'm wondering how often do you restart your computer for this to be a significant issue?  
(Version 3.5)

BOSSA-NOVA  I work a lot with photos, like in Lightroom. After a while computer gets very slow, so I reboot it from time to time.  
(Version 3.5)

MACFOOL  BOSSA-NOVA - Had to wait until I needed to Restart to respond to the question. Firefox 3.5 takes 4 seconds or a little less to open from launch on both machines subsequent to a Restart or Cold Boot.

If this has any bearing (probably not) I run all non-Apple applications from a second partition that will let me install there.

The fact you think you must reboot so often may be the source of your slow launching?

Both Firefox and Safari launch VERY fast give or take a few hundred milliseconds.

Try a cold start into a PRAM zap (thrice) to a Safe Boot, run Permissions repair in Disk Utility, then run your maintenance scripts, trash all caches and then Restart. If things are still slow, well, good luck.

Hope this helps.

BOSSA-NOVA  Firefox 3.5 only takes so long (about 30 seconds) to launch when I first open it after a restart of the system. Subsequent launches while the system is running only take 3 seconds.

I just want to know if others experience the same.

IMHO  BRUCE ANDERSON

I restart my Mac at least every day. And almost every day a second time, when I'll be away of my Mac for some hours. Energy saving, you know. You don't mind about energy shortness and the environment?

ST00P!D M0NK3Y  I'm surprised that Safari is taking 5 seconds to start for you, let alone Firefox taking 30+ seconds. It takes both Firefox and Safari only 1.5-2 seconds to open for me even after a restart. Maybe you should consider reformatting your Mac. I do that every once in a while when nothing else seems to work.

LEOOFBORG  If you think programming is so easy or that the app should be $5, maybe you should code a plugin yourself?

For me, this little plugin is worth three expensive cups of coffee to a guy who does the heavy work.

I wasn't having problems with the plugin myself, but I thank the dev for making fixes. I'll take what I can get.
