How do I disable the Firefox allow page feature.
when I click on allow, it completely knocks me out of the website in which i have to log in again.
Uncertain of your question. If you are getting a re-direct to another page after signing in (common occurence after signing in) check the following setting:
Advanced options panel - https://support.mozilla.org/en-US/kb/advanced-settings-browsing-network-updates-encryption
Link to other options panels - https://support.mozilla.org/en-US/kb/firefox-options-preferences-and-settings
Other- You should check your plugins and update as needed.
