I upgraded to version 18, and it no longer works. I uninstalled, ran CCleaner registry cleaner, reinstalled full version and it still does not work., Windows 7

Posted

I have been running Firefox 17.x with no issues. Updated to Firefox 18 today, and it will not render a single web page. IE and Chrome work fine. Running on 64Bit Win7 Ultimate. 6 Core/16GB Ram. Latest updates for windows, as of this weeks release. I have done a complete uninstall, run both CCleaner and Norton 360 Registry cleaner to ensure previous traces removed. Reinstalled full version. Still cannot/will not render a web page. No noted activity within the browser window. No error codes to provide.

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.

See:

Question owner

I have gone through the firewall config suggestions - no help. I have turned off the firewall - no help. I have cleared cache - no help. Firefox will not render a web page, yet Chrome and IE work with no issue.

I disabled plug-ins - no help.

I would really like to get firefox back on line, because I prefer it to the other options.

Any other suggestions.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.


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.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

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

The other account worked with Firefox

Sooooo . . . . .

Can I clean up the installation on the current account?
