Firefox 33 slow?

[linuxyogi]

I am using 34.0a2 (2014-10-13). I downloaded it from their site so I am on Aurora update channel.

No speed difference.

Addons : NoScript, Ghostery, Bluhell, NetVideoHunter, BetterPrivacy, DownloadThemAll.

Just to update;

Tried Firefox again this morning. Sammiev, you are INDEED right about the scrolling with the mouse. It appears to be erratic on my install; sometimes jerky, sometimes smooth. When I posted my previous reply, it was behaving itself.....but I can now see what you mean!

It DOES, however, run and load at its normal speed.....so my issue appears to be simply the scrolling.

Curious.

Regards,

Mike.

Scrolling is the problem, the more graphics, the worst it is.

I don't use Chrome, but I do use Chromium sometimes and I don't find that is better at scrolling than FF, but then as I said in post #2, FF 33 works fine here for me on Xubuntu 64bit.

I wonder if this is related to graphics card in some way. What is your hardware?

I'm curious about graphics hardware as well. I have an AMD board and Nvidia G210 graphics. The open video driver doesn't like that combination at all, performance and stability are substandard to be kind. Nvidia's driver works great. I wonder if there's something about Firefox' graphics engine that goes crossways with Sammiev's hardware.

When I tried using Unity for the first time everything seemed fine but video playback was choppy so I installed the (#apt-get install lubuntu-desktop) the lubuntu DE and tested video performance. The playback was smooth. Just install lubuntu-desktop and test FF's performance. If FF runs well under lubuntu then Unity is too much for your GPU.

Before having him do that, wouldn't be a good idea if we asked what kind of GPU he has? I mean, I'm running Unity smoothly on an integrated Intel GPU from 2008.

Granted, it could be the GPU, but it may also just be a bug in either Unity or the driver for his GPU. Also, gotta keep in mind that he is 14.10, which is still an RC.

I posted all my info already and it only happens with FF33. I will try testing and older version to see how much difference I notice. All other browsers are smooth as glass.

I'm still willing to bet bug. Excuse me if I seem a bit newbish when it comes to trying to read the output you posted earlier. But, I'm assuming when you said it was a fully Intel system, you meant that you are also using an integrated GPU.

Regardless of that, your system should be able to handle it fine. My old Macbook runs it flawlessly, as does my old Gateway. All Intel. So, this seems odd. Again, though, it's an RC.

How well did disabling smooth scrolling work? Has it been consistent or did it start acting up again?

... It's is much slower with the page movements using the mouse but as quick as it was when I slide the bar up and down with the mouse.

What about when you use the page up and page down keys?

Made it worse than it was.
