How to remove the new tab button in Firefox 3.5

Mozilla Released Firefox 3.5 a while ago and as always there were some UI changes and if you are like me and don’t like getting used to new stuff again and again you definitely wont like these useless changes , one such change is the addition of the new tab button which is totally useless for me and just occupies valuable space on my tab bar as I use double click (on the tab bar) to open new tabs so i just removed it, i will show you guys how to remove it.

Removing it is pretty easy without harming anything, we are going to use the userChrome.css file to edit the layout of Firefox don’t worry it only sounds dangerous but it isn’t in fact this file is used for creating themes for Firefox.

ok now lets do it, at first we need to open the chrome folder where the userChrome.css file resides for that you need to browse to “x:\\Document and Setting\%your username%\application data\Mozilla\Firefox\profiles\%your active profile folder%\chrome\” (where x is your windows installation directory), once you are there, you have to find the userChrome.css file if its not there, don’t worry, its not there for most people just open userChrome-example.css file and save it as userChrome.css and now add these lines to it under the @namespace line:

/* remove New Tab button */

.tabs-newtab-button {display:none !important;}

Once you are done with adding those lines just save the file and restart Firefox and now the new tab button will be gone, if it is still there then there must have been some problem, just leave a comment and i will be glad to help you out.
