firefox 18 displays a blank page when a url is entered


Firefox V18 is installed on a laptop running Windows XP, & has suddenly stopped working, after working ok since being installed. It now displays a blank page when you click on the homepage icon, plus entering a url brings up the word connecting, in the tab, but then displays a blank page with the words new tab in the tab at the top of the page. IE works ok, as does a portableapps copy of firefox 3.5.17.

I have tried re-installing V18.0.1, with no success, I have even tried uninstalling firefox, deleting all remaining folders & running a registry cleaner to see if their was anything causing the install to fail. Firefox still fails to work after all this.

The laptop has been kept uptodate with regards to upgrades, & I have tried doing a system restore to earlier breakpoints, but with no success. Any ideas? TIA

You should really update ther current Firefox 3.5.15 version to a more recent version on the computer that you used to post this.
The Firefox 10.0.12 ESR version is the last official Firefox version that runs on Windows 2000.

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.


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
