Disable number box spinners?

more options

Since updating to Firefox 38.0.5, number fields now have spinners (up and down arrows) on the right side. This can actually be fairly handy on a few sites, but for most other sites, it is proving to be a nuisance, especially because autocomplete is now disabled for these fields. Is there some way I can either disable these spinners or at least make it so they no longer interfere with autocomplete? It would be ideal if I could have a whitelist of sorts to allow spinners on specific sites, but disabling them completely is fine as well.

  • bug 947728 - Provide a way for content to hide <input type=number>'s spinner

Make |-moz-appearance:number-input| the UA style sheet default for <input type=number>, and make the value 'textfield' hide the spinner.


Add code to the userContent.css file.


input[type="number"] { -moz-appearance:textfield !important; }

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

You can use this button to go to the current Firefox profile folder:

  • 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) userContent.css file in the chrome folder (file name is case sensitive)
  • Paste the code in the userContent.css file in the editor window
  • 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 userContent.css.
    Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.txt file

Thank you for the quick response! This works perfectly for disabling the spinners, but it unfortunately doesn't re-enable autocomplete for number fields like I hoped it would. Is there a way to accomplish this as well? I take a lot of surveys and autocomplete saves me the hassle of having to enter my zip code, age, etc. every time.
