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

Also:

• Firefox in safe mode
• Plugin check
• Clear recent history
• Create a screenshot of the problem

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

Thank you.

I tried all of the suggestions listed other than trying to update the video drivers and word wrap still doesn't happen. It is strange that when I receive e-mail that was sent my icloud account using an Apple product (iphone or ipad) there is word no word wrapping. However, if I receive e-mail sent from Microsoft Outlook to my icloud account (which I view in Firefox), word wrapping works just fine. Does this information suggest a solution to anyone. The lack of word wrapping in Firefox just started a couple of weeks ago. Prior to that all was well.

Does it happen to be crashing too?

• Bug 856670 - Firefox crash [@ js::RemapWrapper]

Or in the about:config page what are the values for:

• plan_text.wrap_long_lines

If they are normal, it may be a styling in the site itself.
