- 5Firefox cannot load certain websites
If you were able to load websites until you updated Firefox or until your Internet security software was updated, reconfigured or a new one was added, your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is likely preventing Firefox from connecting to the Internet.
Note: Some Internet security programs can block Internet access even when they are in a 'disabled' state.
In general, you should make sure your Internet security software is up-to-date and remove Firefox from your program's list of trusted or recognized programs, then add it back. For instructions on how to configure some programs, see the Configure firewalls so that Firefox can access the Internet article.
If you connect to the Internet through a proxy server that is having connection problems, you will not be able to load websites. To check your connection settings in Firefox:
- Click the menu button and select ..
- In the General panel, go down to the Network ProxyNetwork Settings section.
- In the Network ProxyNetwork Settings section, click .
- Change your proxy settings:
- If you don't connect to the Internet through a proxy (or don't know whether you connect through a proxy), select No Proxy.
- If you connect to the Internet through a proxy, compare Firefox's settings to another browser's (such as Internet Explorer — see Microsoft's guide to proxy settings)(such as Safari — depending on your OS X version, see Mac OS X 10.6: Enter proxy server settings, OS X Lion: Enter proxy server settings, or OS X Mountain Lion: Enter proxy server settings).
- Close the Connection Settings dialog.
- Close the about:preferences page. Any changes you've made will automatically be saved.
If you find that changes you make to your Firefox connection settings are not remembered when you restart Firefox, see How to fix preferences that won't save.

- In the Time Range to clear: drop-down, select Everything.

If clearing your cookies and cache did not enable you to load the websites that did not work in Firefox, you should check your computer for malware. Certain types of malware are known to target Firefox and can prevent it from loading various websites: https://psychicruinspersona.tumblr.com/post/638424620484165632/adobe-flash-player-9-for-mac-free-download.
- If you have an antivirus or Internet security program, update its detections database and do a full scan of your system.
- If you still have problems, follow the instructions in Troubleshoot Firefox issues caused by malware.
A Firefox extension could be causing the issue, especially the ones that have network access and/or those that rely on manipulating webpage content. Try disabling your extensions in the Add-ons Manager one by one and then reload the page. See Disable or remove Add-ons and Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for more information.
