URL is not valid' is displayed and the page does not load. This happened to all web pages (including mozilla.com). This also happens when I go to my homepage - iGoogle. This only happens when opening Firefox (and going to my homepage) or in Private Browsing. Reproducible: Always Steps to Reproduce: 1.None 2. 3. Actual Results: N/A Expected Results: N/A
Does this also happen in safe-mode / with a new profile? http://support.mozilla.com/en-US/kb/Safe+Mode http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile
Reporter told me by e-mail that there is no problem in safe-mode. That probably means that the issue is caused by an add-on and that this bug is INVALID for the Firefox product. http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes Please notify the author of the extension so he can fix the problem.
