A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Also try uninstalling and the re-installing any Security program.

I have no security software, anti-virus, or firewall on my mobile phone, yet the problem still persists using that device. I have tried loading the pages while using home Wi-Fi, and while using LTE data, and still the problem persists.

Again, pages load correctly using Chrome or IE.

Edit: While admittedly I do not know how to do those things you suggested without more specific directions, I am incline to believe that since the problem persists on my mobile device (with no security or anti-virus), still persists on this computer (with Eset security) and still persists on a second computer (new windows 8 computer only running pre-installed windows defender), that this may not solve my problem.

Have you tried clearing Cache and Cookies?? Are you using same log-in preferences for this site on all the devices??

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.

Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

• Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
• Under "Time range to clear", select "Everything".
• Now, click the arrow next to Details to toggle the Details list active.
• From the details list, check Cache and Cookies and uncheck everything else.
• Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Websites don't load - troubleshoot and fix error messages

Firefox can't load websites but other browsers can

Hello again,

Thanks for responding so quickly.

I have cleared Cache and Cookies, yet the problem is still persisting.

I am not sure what you mean by, "using same log-in preferences for this site on all the devices??" The second computer is my wife's computer and she is the one who originally noted the discrepancy in the different browsers loading the same website differently. I don't know if that response helps in determining if we are using the same log-in preferences for the site. As to actually accessing the site in question, I am not logging in or anything, I am just typing the web address in and noticing it does not render the same as in Chrome.

I have been telling her to just use Chrome and not deal with this issue, but she is having issues with Chrome and her new Windows 8 computer, in which she notices that while using Chrome, her memory usage and CPU usage are peaked at 100%, making her computer run extremely slow. Alas, that is a completely different problem for a different forum!

Thanks,

Alex

Any other ideas or suggestions? I am completely at a loss. I would prefer to continue using Firefox, but it is difficult with my ongoing problem.

Please advise.

Thanks!

Amazon.co.uk seems to be having real troubles as of late on Firefox. It's annoying because I can't use the site properly without a working CSS.
