Firefox suddenly blocking ads
Firefox has suddenly started blocking ads - but I don't want it to and I don't have an ad-blocking extension installed. Can anyone help?
Firefox version 24.0
Extensions: Classic Retweet, Faviconize, PageRank Client 1.2, Password Export, PDF Download, Roomy Bookmarks, TabMixPlus, Web Developer, XMarks.
I use Avast as antivirus but DON'T have the Avast ad-blocker.
I need webpages to display ads for my work, for which I must use Firefox, so any suggestions would be gratefully received.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window.
You can try to rename or delete the prefs.js file and possible numbered prefs-##.js and user.js files to reset all prefs to the default value.
If images are missing then check that you aren't blocking images from some domains.
- Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.
- Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
- Check "Tools > Page Info > Media" for blocked images
- Select the first image link and use the cursor Down key to scroll through the list.
- If an image in the list is grayed and "Block Images from..." has a check-mark then remove this check-mark to unblock images from this domain.
Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
- Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.
There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.
