Hello,

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 (e.g., mail you are composing, online documents you're editing, etc.).

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

Did this fix your problems? Please report back to us!

Thank you.

I unchecked Hardware Acceleration. That didn't help; still extremely slow.

I started in Safe Mode with Extensions disabled. That didn't help.

I switched to the Default theme. That didn't help.

I tried manually disabling all Extensions. That didn't help.

I tried all the ways to upgrade my graphics driver, but could not figure out how to do it. (Also, the instructions list a lot of potential problems, so I hesitate to do that without further input from you.)

Do you think I should try uninstalling and reinstalling? I definitely want to keep all my Bookmarks! Will they be retained unless I specify not to retain them? (VERY IMPORTANT TO ME!)

Also, after I did the Extension disabling, the "Progress Bar" at the bottom of the page, which tells you how fast pages are loading and when they are done loading, disappeared (?) Also, the text at the left-hand side of the bottom of the page that charts what things are loading, disappeared as well. After I re-enabled all the Extensions, these two elements did not reappear (after restarting).

A clean reinstall will not delete bookmarks, addons etc.

hello, such issues can also be caused by a firewall/security software which doesn't properly recognize & therefore blocks or slows down new firefox versions: Fix problems connecting to websites after updating Firefox

So, do you recommend I try that? (Uninstalling and reinstalling.)

RE: Firewall security software. I don't have a firewall installed. I use AVG anti-virus.

firewall/security software includes AVG.

And yes, a clean reinstall is suggested.

Can you post instructions on how to fix and firewall/security potential problem here? (FF is SO SLOW that going to other pages takes ages!) Arrghh! Taking my whole day! :'(

Shall I try the clean reinstall BEFORE dealing with the firewall/security issue?

hello, this is explained in the link in my posting above. in essence remove all rules regarding firefox (& plugin-container.exe) from your security program and let it detect the new browser version again...

O.K.! I did an uninstall and clean reinstall, and my FF is now much faster!

I wonder if I had somehow picked up some bugs or corruption in my original FF? For example, I had never seen the "progress bar" before (that I mentioned above) before downloading Firefox 22 for the first time. And there was also a mysterious "download arrow" next to it. My clean install of Firefox 22 does not have either of these...

Would be interested in your thoughts. Somewhere in the FF Support pages, I saw a reference to the possibility of downloading a "Fake Firefox." Do these exist?

Phillip, thank you for your suggestion re: firewall issues. If I have more problems with speed, I will check that out as well. (It still doesn't load major news sites as fast as before.)

Thanks to both of you for your prompt advice! This was a huge problem for the last couple of days, and I REALLY appreciate getting some help with it!

I found my problem was due to the proxy setting - under Tools-Options-Advanced-Connection. Somehow this got set to "Use system proxy settings". I changed it to No Proxy, and now Firefox loads in a flash - before it would hang for 30+ seconds.
