You can switch the bidi direction of any input field or text area with the Ctrl+Shift+X keyboard shortcut.

Thank you cor-el.

Is it possible to set the DEFAULT value to ltr? textbox-input-box { direction:ltr !important; } does that in the Search Bar.

This code in the userContent.css file works for me with a ltr locale (en-US)

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

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

• Help > Troubleshooting Information > Profile Directory: Open Containing Folder

/* about:config */
@-moz-document url-prefix(about:config) {
 #textbox { direction: rtl !important; }
}

This code in userContent.css also works for me on the about:config and about:addons pages (not on about:home).

.textbox-input { direction: rtl !important; }

Hi cor-el,

Thank you so much. I’m really impressed!

When using .textbox-input-box { direction: ltr !important; }, the entire layout is changed (the magnifying glass is moved too). I could use .textbox-input-box { text-align: left !important; }, but I’d be glad if you have a better solution.

May I request your help with three more issues? I hope it’s not too much of a trouble.

1) The default TEXT direction of the Location Bar is also rtl. Any idea how to change that (only the text, not the layout)?

2) Could you please have another look at this post?

It might have to do with the answer you’ve given me here.

3) I’ve written a small extension for my personal usage. I’d like a toolbar button’s tooltip to consist of 2 lines, and some parts of the its text to be bold. Is it possible to do that in a dtd file, or the only way is to use properties and/or js files?

Thanks again. I appreciate your help.

For input fields in the user interface you can add code to the userChrome.css file below the default @namespace line.

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

*|*.textbox-input { direction: rtl !important; }

Thank you. You've been very kind.

You're welcome
