Hello, how can the zoom on the URL window be disabled? Instructions on how to do this in about:config for previous versions no longer work. Thanks.

Hi mike.porter1, please ignore the spam message with a phone number -- that's not official and we don't know what they will do to your system if you engage.

Hi Mike, well, currently you need to use custom style rules in a userChrome.css file to tame the enlargement. That might be a foreign language to you, but stick with me. Although there are several steps and it might take 10 minutes, you can do it.

(For anyone who already has a userChrome.css file set up, you just need to add the rules you downloaded under (A) to your file.)

(A) Download a rules file

Use the downloads list on the toolbar to open the downloads folder directly to the new userChrome.css file. (See attached screenshot)

Minimize that file browser window for later reference.

(B) Create a new chrome folder in your profile folder

The following article has the detailed steps for that (#1, #2, and I recommend #3)

I have videos for both Windows and Mac in case the text is not clear.

(C) Move the userChrome-ZeroEnlargement.css file you downloaded in Step A into the chrome folder you created in Step B

(D) If you do not already have a userChrome.css file, Rename the userChrome-ZeroEnlargement.css file

Highlight userChrome-ZeroEnlargement.css and choose Rename (using whatever method Finder offers). Carefully remove -ZeroEnlargement and press Enter to save your change. The final file name needs to be userChrome.css or Firefox will never find it.

(E) Set Firefox to look for userChrome.css at startup -- see step #6 in the above article.

The next time you exit Firefox and start it up again, it should discover that file and apply the rules.


Once you start tweaking the interface this way, you'll probably find more and more things you want to do. I suggest bookmarking the pages where you get the code for future reference because changes to Firefox may break them and it's easier to request an update if you can find the source.

You may have seen a post or received a notification regarding support for Firefox or Thunderbird with a link to another site or a phone number being posted. This is a scam and is not a method to receive support from Mozilla. Mozilla does not have telephone or email support. Please do not click on the link and do not interact by calling any phone numbers or email addresses listed. I apologize for any inconvenience caused. You are currently posting on the official Mozilla website and will receive assistance here.
