You can check the home page setting to see if the about:preferences page is appended (|about:preferences#general). This can happen if you click "Use Current Page(s)" to set the home page.

You can check the home page setting

• Tools > Options > General > Startup: Home page

• https://support.mozilla.org/kb/How+to+set+the+home+page

Firefox supports multiple home pages separated by '|' (pipe) symbols.

You can pin the tab with the about:preferences page to prevent including about:preferences to the home page setting if you want to use this button. To set a single page as the home page you can drag the globe/padlock to the Home button.

I have done the suggested option to stop the "options" tab from opening every time I open my browser. It did not stop it from happening. Can you suggest something else to fix the problem? Thank you

Type about:config<enter> in the address bar. If a warning screen comes up, press the Be Careful button. At the top of the screen is a search bar. Type browser.startup.homepage.

Click on this to edit. Look for |about:preferences#general or |about:preferences and remove it.

Thank you for your help. What comes up on the screen is the following:

"browser.startup.homepage;http://my.xfinity.com/?cid=xfinityconnecttocomcastnet#1|about:preferences

browser.startup.homepage_override.buildID;20160105164030

browser.startup.homepage_override.mstone;43.0.4

services.sync.prefs.sync.browser.startup.homepage;true"

Can you tell me exactly which one to delete? Thank you

What globe/padlock are you speaking of?

Also, I have nothing that says: "|about:preferences#general or |about:preferences" to remove. Thank you

Remove what I highlighted.

He means the icon at the far left of the address bar. It only shows a padlock if the page is secured.

Thank you, both FredMcD and cor-el, for your help. The problem is now fixed. Thank you again.

Glad to help. Safe Surfing.
