You may have zoomed web page(s) by accident. Reset the page zoom on pages that cause problems.

You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

If you have made changes to Advanced font settings like increasing the minimum/default font size then try the default minimum setting "none" and the default font size 16 in case the current setting is causing problems.

• Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow pages to choose their own fonts.

• Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but to use an extension to set the default page zoom to prevent issues with text not being displayed properly.

You can check the font.* prefs on the about:config page and possibly reset user set (bold) via the right-click context menu to the default value.

Thanks!! I had the NoSquint addon enabled, I disabled it and all seems ok so far. I have had NoSquint for months without any problems, BUT I hadn't been to these sites until recently. Thanks again! You rock! :-)

You're welcome.

Did you check the settings in NoSquint to make sure that you use full page zoom and aren't using "Zoom Text Only"?

Error 1001 Ray ID: 1dccbcba20971840 • 2015-04-25 20:18:27 UTC DNS resolution error What happened?

You've requested a page on a website (qsurvey.mozilla.com) that is on the CloudFlare network. CloudFlare is currently unable to resolve your requested domain (qsurvey.mozilla.com). There are two potential causes of this:

   Most likely: if the owner just signed up for CloudFlare it can take a few minutes for the website's information to be distributed to our global network.
   Less likely: something is wrong with this site's configuration. Usually this happens when accounts have been signed up with a partner organization (e.g., a hosting provider) and the provider's DNS fails.

I will check that. Thanks again :-)

NoSquint was and is set to full page zoom and I am having the same errors again. I can just use the default zoom method with ctlr + and _ ;-)
