Using Windows vista and Firefox 4 hangs almost every time

Question

I have just installed Firefox 4 and now almost every time I open Firefox it hangs. I have checked all the suggested solutions but nothing has had any effect.

Hi,
Try '''disabling graphics hardware acceleration'''. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to '''restart Firefox''' in order for this to take effect, so '''save all work first'''.
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please '''check for updates for your graphics driver''' by following the steps mentioned in the following Knowledge base articles:
* '''[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]'''
* '''[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]'''
Also try to clear the firefox cache etc.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the '''[[Clear your cache, history and other personal information in Firefox]]''' article.
