Testing customisations
If you want to test the effect of changing settings in userChrome.css or userContent.css, it's sometimes handy to activate a setting then deactivate it to contrast its effects in the browser.

Because you must close the browser and then reopen it before a new setting takes effect, the process is a little involved. You can speed things up a little by using comment codes to "comment out" a setting; that way you don't have to insert, delete and re-insert code to make the changes. By adding /* at the beginning of a line and */ at the end of a line, you turn everything between into a comment, which is ignored by the browser.

So, for example, you can use the following code in userContent.css to stop Web sites from displaying blinking text: blink { text-decoration: none ! important; }

If you'd like to turn blinking text on again, you can do so quickly by commenting out the line, thus:
/*
blink { text-decoration: none ! important; }
*/

No text
Eliminate the text below the toolbar buttons in Mozilla and gain a smidge more display space by adding the following lines to userChrome.css: .toolbarbutton-menubutton-button > .toolbarbutton-text, .toolbarbutton-1 > .toolbarbutton-text { display: none !important; }
