Are these the thumbnails that Firefox creates and displays on the "new tab" page, or thumbnails captured and displayed by an add-on? If it's an add-on, which one is it?

no, these are firefox generated. some are fine, some not so fine. youtube looks like a bad eye test. I'm sure it's in the settings, although in general Opera renders its dials much more sharp. On the other hand, Opera's thumbnails never get updated.

I would also love to space out the individual dial blocks maybe a few more pixels between them. haven't figured out that yet either.

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.

Note that you can set the number of rows and columns that appear on the about:newtab page by modifying these prefs on the about:config page via a double-click.

• browser.newtabpage.columns (3)
• browser.newtabpage.rows (3)

here are two shots, from opera and from aurora. thanks for the helpful replies.

Hi Jeff, what is the speed dial you're using? I don't recognize the captions above the thumbnails.

That might be the answer. I changed speed dial extensions and now use the FVD Speed Dial, which offers many more options and produces some excellent images. Thanks for all the helpful responses and suggestions.
