If you use extensions (Tools > Add-ons > Extensions) like Adblock Plus or NoScript or Flash Block that can block content then make sure that such extensions aren't blocking content.

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

If images are missing then check that you aren't blocking images from some domains.

• Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"

• Check that images are enabled: Tools > Options > Content: [X] Load images automatically
• Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"

• Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).

If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.

Make sure that you do not block third-party images, the permissions.default.image pref should be 1.

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

this seems an automated/ready-to-serve reply

none of the images or videos are blocked by adblock/noscript which i use as addons. all suggested options are in place.

Did you check the Tools > Page Info > Media tab to make sure that images weren't blocked?

Are you using Adblock Plus on any of the computers?

You can create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

See:

• http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
• https://support.mozilla.org/kb/reset-firefox-easily-fix-most-problems

Note that "Reset" creates a new default profile with a time stamp appended to identify it and tries to recover settings like bookmarks and history and passwords and cookies and auto-fill data from the old profile, but you lose data like extensions and other customizations.

• http://kb.mozillazine.org/Profile_folder_-_Firefox

Firefox 15+ versions will move the old profile folder to an "Old Firefox Data-##" folder on the Desktop that gets a number appended if you use reset more than once.

You can recover more data from the old profile, but be cautious.

where's Tools > Page info? FF 16.0 has 'Options'.

been using Adblock past 3-4 yr without issue. sometimes if i Uninstall > Reinstall FF,with all the extns incl Adblock Plus, the issue resolves (did that a coupla times in the past) - but i don't want to do that now as it's a hassle to customize my FF browser all over again.

creating a new profile and tfring old profile files seems a hassle.

if all fails, plan to uninstall/reinstall FF as a last resort.

You can press the F10 key or tap the Alt key to bring up the "Menu Bar" temporarily if the menu bar is hidden to access the Tools menu.

thanks cor-el. i checked 'page info > media' and images are not blocked

Do any of the missing images show up in Tools > Page Info > Media ?

Did you try Safe mode?

Note that extensions like Adblock Plus continually update their filters and it is quite possible that content gets blocked by a too general filter rule.

thanks. disabling Adblock Plus did the trick.

btw, any other non-problematic addon to block pesky ads/flash

Hi all, I am experiencing the same problem here. I have not installed any of the Adblock Plus or NoScript or Flash Block add-ons. Now, images are blocked after a while using ff. I found that by clearing the cashe ( Options -> Advanced -> Network -> Cashed Web Contend -> Clear Now) the problem is temporary solved (until cashed web content reach 25+MB)

Any ideas?

the 'disable automatic cache management' option is unchecked in my 'network' options you've mentioned and i don't face any problem like yours. you can try leaving this option unchecked and see.

Thank you for the answer drapatil, Unfortunately, that is not the case. I had it unchecked and I have also tried it checked with several values in the limit cashe...

Do you see those images in Tools > Page Info > Media ?

Did you try Safe mode?
