No one has had this issue and or knows how to resolve it, I am surprised.....

You can set this maximum via this preference on the about:config page.

• browser.urlbar.maxRichResults

Unfortunately Firefox sets a maximum height to this drop-down list and shows a scroll bar. You will have to use code in userChrome.css to increase the max-height of this container.

Add code to the userChrome.css file below the default @namespace line.

• http://kb.mozillazine.org/userChrome.css

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* URLBAR: drop down list - restrain max-width */
#PopupAutoCompleteRichResult {
  width: 800px !important;
  max-width: 800px !important;
  margin-left: 0 !important;
}

/* URLBAR: max-height for 12 items visible without scrolling */
#PopupAutoCompleteRichResult .autocomplete-richlistbox {
  height: auto !important;
  max-height: calc(30px * 12) !important;
}

• create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
• use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
• paste the code in the userChrome.css file in the editor window
• make sure that the userChrome.css file starts with the default @namespace line
• make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
  otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Thank you, I greatly appreciate it and will try and see if that works. Regards

Ta da, that was it, sir you are a gentleman and a scholar and I thank you. Regards

Now if I could only just keep the selected websites that I prefer to go to rather than the ones that I have just been too a few times however that eventually push the selected websites off the address bar drop down menu.....

Does anyone know how to do this? Thank you

That triangle is pre-programmed to search your history and apply a formula called "frecency." You can adjust how frecency is computed, but you can't completely replace that approach with your own list. Bookmarks could be useful for that, either using the Bookmarks menu button, the Bookmarks toolbar, or the built-in matching feature of the address bar where you type a couple characters and your bookmarked sites that match are listed.

(By the way, I experimented with the "weights" listed on the following page but couldn't change my list. Perhaps it's not retroactive, or I just don't understand it. https://developer.mozilla.org/docs/Mo.../Frecency_algorithm)

Okay thanks, I will work with it and see what I can come up with. Regards
