I have a similar problem with opacity. I just set the opacity of my main DIV to 85% , then the page is very very slow to render. I have interpid ibex with ; - Intel Core 2 Duo - 2 GB RAM DDR2 - nVidia GeForce Go 8600M GT with non free drivers. It does not happen with other configurations I test . I am not sure the 2 others bugs are realy duplicated of this one because I do not have other problem of slow rendering.

[Bug 207454] Re: Firefox is VERY slow rendering pragprog.com; becomes almost unusable
I think the problem is in css file of http://www.pragprog.com/,
especially, high.css file.
I downloaded main html file and css files from the site to my local
machine (xubuntu 8.10, restricted nvidia driver, FF 3.0.1) and tested
with some combination of them. Finally I think I found the root of
trouble.
You can see below code in high.css file.
body {
background-color: #858072;
color: white;
padding: 0;
margin: 0;
-moz-opacity: .99; /* Firefox bug fix */
}
The last line -moz-opacity: .99; /* Firefox bug fix */ is today's main guest.
It's a kind of trick for solving FF 2.x bugs.
However, in FF 3.x, it makes our headache. :-)
I hope The pragmatic bookshelf removes the line or changes value from
.99 to 1 or Firefox team makes patch to around this kind of crash.
Or... you can use alternative way to solve this crash with stylish
plugin. I'll explain how to do it in my blog
(http://classpath.egloos.com/4622029). It's Korean blog, but I'll try
write it in English.

According to my browser history, I visited PragProg.com on 7-9-08 and I recall *not* seeing this problem then.

I have the same problem with Firefox 3.0.1, 64 bit on 64 bit Ubuntu 8.04. Problem exists with all extensions disabled, and also with noscript enabled, so I don't believe it's a javascript problem. I am running the restricted nvidia driver, I will later try and see if it improves by switching to the open source nv driver. Note that the site renders quickly for me in FF 3.0.1 on a seperate vista machine with very similar specs.

I can confirm that under the same kernel, linux-generic 2.6.24.18.41, restricted nvidia driver has the 10 second or so screen freezing delay, and the free nv driver has no delay. I am unable to get linux-generic 2.6.24.19.21 working with the restricted driver at the moment, so I can't report on the latest kernel under the restricted driver, but the nv driver on latest kernel works fine. -- Firefox is VERY slow rendering pragprog.com; becomes almost unusable https://bugs.launchpad.net/bugs/207454 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
