Not sure if I can reproduce this completely. The website uses
about 50% CPU initially, and drops to 6% when the Right Now section
is loaded after clicking on the blue left arrow thingy. So, I do
see a difference.
But it never "thrashes" (which I interpret as "100% CPU
always"(?)), so this doesn't look especially problematic to me.
What processor/speed does you Mac have? If you're able to run
Aurora, I figure it should be at least 800 MHz G4, right?
TFF 17.0.3 & 19.0 with G4 PowerBook 1.33 GHz (reduced to 667
MHz in Energy Saver).
Weird, tried it again, and now it's only using ~30% initially,
dropping to 6-7% when clicking "Right Now". Maybe it's different
depending on which ads are loaded, or some other stuff that I don't
get to see here in Europe?
not (only that clicking Right Now with no JS doesn't have an
effect, of course), so that's even weirder.
I am not sure if this is relevant here but I could not find a
more relevant topic. My issue is that CPU utilization by TenFourFox
is kind of high. I have 3 tabs open (Gmail, Wired and this one) and
the CPU use is between 90 and 100 %. TenFourFox works fine, it is
just not very responsive. I have tried TenFourFox 17.0.2 and 17.0.3
with similar outcomes (I think 17.0.2 might be slightly less CPU
intensive but I am not sure). I use a PowerMac G5 11,2 (dual 2.3
Ghz, 5 GB RAM, OS X 10.4.11).
I have the same issue on lubuntu with FF 19. Processor usage
hangs at 35% until RIGHT NOW is loaded, then after loading it idles
at 4%. Looks like something in the FF code for these legacy
Phil, maybe your Intel Mac or Windows PC is just so fast you
don't notice it over there?
Eugene, again, I don't see this here (with Wired and Tender),
side. Do you see the same load in Safari with these three websites?
You could also try TenFourFox 19 (unstable branch) to see if it's
faster for you.
have the same problem with our page, where I'm even using CSS compression:
http://www.seaplane.aero/en/ Ok, on the Home page there's a flash video background, which 10.4Fox doesn't know.
But what about the rest? Try sliding over the menu - its buttons are supposed to go smoothly down. And what about the slideshows under Versions?
Apart from that the HTML5 videos of youtube are unwatchable! How exactly do you see surfing without watching vids? Is it woth ditching Flash?
There's also a guy, who fixed the flash update issue so you can fool the websites that you use Flash 11.5! Using this with Safari makes the youtube videos FLY on my
iMac G5 2GHz, 2GB RAM, 128MB VRAM, OS X 10.5.8.
I appreciate your work for keeping us safe with this browser, but is it really an option - using two browsers in order to surf safely and watch youtube normally?
Also: my system is pretty clean after using onyx, ifreemem and the HDD has 85 GB free space.
Looking forward to hear what's the matter with browsing our website! ;)
to be honest, I'm frustrated as well sometimes about the loss of
plugins in TenFourFox, but it can't be helped. It's either option
one: using Flash and staying at an outdated and insecure html
rendering core, or option two: offering the most recent
Since there is Safari/Camino/Omniweb/Opera 10 where Flash still
works, I'm actually glad there's TenFourFox that goes for the
second option. And of course you can use a two-browser strategy. If
you use Safari for stuff that needs Flash, and do your online
banking and other stuff that needs security and more modern html
features with TenFourFox, that perfectly fine to me. By the way I
do use html5 video for YouTube. It's not exactly the smoothest
experience on my PowerBook G4,but it's tolerable. If there's no
html5 option for a specific video, I download it and watch if
I tried loading http://www.seaplane.aero/en/,
however I'm getting an Internal Server Error repeatedly, so I can't
reproduce your problem with this page right now. Have you tried
using a fresh Firefox profile or disabling add-ons to see if it
my iMac has one G5 processor indeed. Besides, I experience performance problems only on some websites, which also include our www.seaplane.aero, and the rest – not more than in safari.
Sometimes our webhosting sucks, therefore maybe will work again later or just by typing in "seaplane.aero". I can open the site any time now, sitting in Germany.
If it doesn't work, could you please give me your location and browsing data so that I can kick our hosting provider's ass? ;)
The website loads now, it takes about 5 seconds. The menu to the
left works, and the buttons go down smoothly. They're not pressed
instantly, but this effect rather looks like intended to me, a sort
of quick animation of the buttons. It's very smooth, and it looks
cool. The slide show is also played normally, with a new picture
every 5 seconds. I see no processor thrashing or slowness
whatsoever. I'm on a PowerBook G4 1.33 GHz.
Oh man, can't believe the older G4 handles it better than a G5 with the OS Leopard!
I've just installed the unstable 22.0 release and had unfortunately to discover...
1. that the problem with the menus is still there and the CPU is literally freaking out when hovering over it, even the cursor is getting slower and the CPU fan nose tells me that my iMac is just about to take off! Same happens with slideshow and also its controls on the right, and...
2. there is no language files available for v. 22.0 yet. I think that if you gather usage data about 22.0, it will be very useful to offer language files - this way you could reach much more people and gather more data.
You're right, the animation in the menu is intended to be smooth, as one of the contact form fields.
Maybe the difference is that you use 10.4Fox for G4 and mine is for G5? I mean, they seem to be kind of different programs.
My PowerBook is also on Leopard. I don't have a G5 here to test
with, however on my G3 Pismo (400 MHz(!), Tiger) the website, once
it's loaded (after about 35 seconds), the menu is a bit laggy, but
I see the same smooth animation for the buttons, and the website is
Unless it's a G5 specific issue, I'm pretty sure the website
will be fine if you try a fresh user profile. The easiest way to
test this quickly is this:
1) quit TFF, and make sure it's really quit, which may take a
2) in the Finder, go to your user Library/Application Support and
move the Firefox folder to your desktop. This folder contains your
profile with bookmarks, add-ons etc.
3) start TFF. It will act like it's never been started before.
4) visit the site in question and observe performance
5) Now quit TFF and move the Firefox folder from your desktop back
into Application Support. There will be a new Firefox folder in
there, which can be replaced. Make sure you're replacing the right
thing. If unsure, back up you Firefox folder to another harddrive
If the site loads normal now, you know you probably have an
add-on that slows stuff down, or a whacky preferences
configuration. If this is the case, we'll see what we can do
2) there's no Firefox folder, instead a Mozilla folder. Probabyl should have mentioned "user" before /library/application support ;)
4) don't know how to start this mode, couldn't find it. If you simply meant that I should look how the site works now and test the mentioned instances, then I did it and it's still the same.
The only add-on I use is the AdBlockPlus 2.2.4, which was during this last test disabled everywhere before action (1).
The animation of the buttons is smooth as is should be, if you hover just a single menu item, but the CPU load is up to 75% an the iMac starts wheeping. If you go up and down the menu bar, the processor load reaches 78% sometimes and the average is around 60%. The most annoying lagg happens while hovering Versions, making the submenu fold out.
What do you mean by "whacky preferences configuration"? The browser's prefs? How should they be best?
Cool! The German language installation worked! Many thanks!
If it's still the same with a fresh profile, then there may
indeed be a difference in the G5 version. My PowerBook doesn't go
over 50% CPU hovering up and down the menu, which I would consider
normal. However, >70% istn't completely unusable. In Safari, I
see exactly the same slight lag between buttons.
If you click "Help", then "Troubleshooting Information", you'll
get a list of modified preferences. But it's not necessary. There's
not much I can do right now. It needs to be tested on another
I was away on business, so sorry I couldn't look at this sooner.
On my own G5 I do see what you are referring to, but because of
known threading problems on 10.4, I can't really distinguish
between those and anything specific to your 10.5 system. The first
thing is to upgrade the allocator, which is issue 218, and then to
see what remains. However, the highest priority for version 24 is
BaselineCompiler, so I cannot make any guarantees about when that
can be updated.
