When I open Firefox no problem, but when I change the use of my graphics card (ex. switching to chipset intel HD), my Firefox lags for everything, typing, scrolling... I have to restart it everytime.

Reproducible: Always

Steps to Reproduce:
1. Use Firefox, and switch to Intel HD Graphics chipset (and vice versa)
2. You will lag
3. You have to restart Firefox to solve this problem...
Actual Results:  
My Firefox lags when I want to scroll, typing...


MBP i7, 2.66 GHz, 8 Go 1067 MHz DDR3, MAC OS X 10.6.7, use SSD Vertex 2 and use theses add-ons:

- Downthemall
- Element Hidding Helper (ADBP)
- Firebug
- Page Speed
- Web developper
- Xmarks
Please post the graphics section from about:support when using the Intel HD Graphics chipset.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode
Version: unspecified → 4.0 Branch
Hello,

My graphics section : http://yann.tobehost.net/partage/index.php/Capture%20d%E2%80%99e%CC%81cran%202011-04-19%20a%CC%80%2010.52.48.png

No, it works better in Safe Mode, but I can't understand how of these plugins can do that...

Thanks.
Safe Mode also disables hardware acceleration. That is the most likely cause. Your graphics section doesn't show the driver or version. Can you provide that info?
See if this helps: try  Preferences > Advanced Tab and under Browsing, uncheck "Use hardware acceleration when available"
Reporter, do you have anything new to add about this issue?
Hello, thanks for your tip, it was helpful :-), I've disable the hardware acceleration mode and it works!

But I think, there is always a problem with this feature...
Considering comment6, setting resolution to Resolved WFM.

Intel HA is pretty much dead in the water.
