Intermittent failures where pages open in IE but Firefox shows blanks usually point to a local configuration, profile, or extension/plugin problem rather than the ISP. Earlier replies suggested cache/firewall tweaks and found a firewall rule difference that blocked Firefox while allowing IE. The checklist below adds focused diagnostics and next-level fixes that were not covered in detail in the thread.

Start Firefox in Troubleshoot Mode (Safe Mode) to temporarily disable extensions, hardware acceleration and other customizations. On Windows this can be done by holding Shift while launching Firefox or by running:

firefox -safe-mode

If pages load in Troubleshoot Mode, the cause is likely an extension, theme or hardware acceleration; disable or update the offending add-on. See Mozilla’s Troubleshoot Mode / add-on guidance for details. (support.mozilla.org)

Test with a clean profile to rule out a corrupt profile. Use the About Profiles page or start the Profile Manager:

firefox -P

A new profile that works indicates the old profile is corrupted; migrate bookmarks/passwords rather than repeatedly reinstalling the program. If a fresh profile still fails, consider a Firefox “Refresh” (creates a new profile while keeping bookmarks/passwords). See the Profile Manager and Refresh documentation for safe steps. (support.mozilla.org)

Do a few quick network and logging checks: flush the system DNS cache:

ipconfig /flushdns

inspect the hosts file (C:\Windows\System32\drivers\etc\hosts), verify Firefox’s Connection/Proxy settings match the system, and disable or update plugins (Flash/Java) if present. Capture the browser state with the Troubleshooting Information page (about:support) when collecting details for diagnosis. (support.mozilla.org)

These steps extend the thread’s work (cache/firewall/reinstall) with low-risk diagnostics that isolate profile, add-on, and environment causes. If the issue persists after them, the collected about:support data and exact Firefox/OS versions are the most useful next pieces of evidence for deeper analysis.

Hi, I have been having the same problem recently.

The mozila was working fine, but then when the latest version was installed, I couldn't see anything! All the pages that I tried returned blank. I tried the same urls with explorer and where displayed correctly.
I run a full system virus scan with my Panda Anti-virus, but still nothing.
I unistalled firefox and donwloaded it again, but still nothing. The firefox that I have at my laptop works OK, but I don't remember if it is the updated version.

Does any one know how to help us fix our problem?

I have checked the firewall of my antivirus. For some strange reason, even though I could use the mozila with no problems, the settings looked changed.
In details: I opend my Anitvirus and went at the tab that said firewall. I clicked at the setting and it had several programs and how these programs should connect to the internet.
I saw that the settings of the IExplorer were diferent than the settings of the Mozila. Since I could connect to the internet using explorer, I changed the settings of the Mozila to be the same as the Explorer and I could use Mozila again

thats good to hear, i can probably guess why it change it is possible that when you uninstalled mozilla your settings change. thats probably one of the many reasons why that happen.

Actually I was having the error before I unistalled. All of the sudden it stopped working. That is why I unistalled in the first place.
You might say that the settings changed when a new version of firefox was installed, but my laptop continued working fine, and none of my friends had that problem
