Where are the settings for blocking installation by websites stored, and how can you edit them?
An external app (my work Lotus Notes webmail) wanted to install something and I accidentally clicked "deny" and "remember this", when I wanted to allow it. Now I have no idea where I can remedy this. Any ideas?

Tools > Options > Security - Warn me when web sites try to install add-0ns = hit the Exceptions button
Highlight that web site and then click the Remove Site button.
Thank you for the reply, and sorry for the delay in getting back to you. Unfortunately, that doesn't seem to have solved the problem, and my Notes webmail still doesn't respond when I click on the button to send mail.
Does this security option only relate to the installation of Firefox-specific add-ons, or does it refer to everything?
Thanks.
Where do you click that button?
Is that on a web page?
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
