In order to allow or disallow third party plugins for certain websites in Firefox you need to perform the following steps:
My website stylesheet sets the overall font size to be 76.1%, this was working fine except for Firefox and the pre tag, it would render fine in Internet Explorer but Firefox would shrink the font size down. In order to get around this I used the following CSS:
pre, code {
font-size: 123.9%;
*font-size: 100.0%;
}The asterisk in front of the font-size command means it is strictly invalid CSS which is ignored by Firefox but is still parsed by Internet Explorer.
Or how I learned to stop worrying and make Firefox look like Chrome.
When Google Chrome was released it suddenly dawned on me that Firefox did not blend very well with Windows Vista. The main problem is the complete lack of transparency which when comparing Firefox with the standard Vista dialogs was an obvious difference. As with most things Firefox this problem has been solved by an add-on called Glasser (external link). This is currently an experimental add-on so you will need to create a Mozilla login before you can download it, but I have been using it successfully for weeks now with no stability problems. It does cause some issues with the menubar but these can be solved by installing another add-on called Personal Menu (external link), this hides the menubar and moves it elsewhere onto the browser window.
