CSS Hacks for Firefox 22

These are my legal CSS Hacks for fixing web browser quirks or outright bugs. Please enjoy, I have been working on them for years. May it help you if you need them. Please read here first: [What are these CSS Hacks Anyway?] Then check my [Live CSS Hacks Test Page] and also [BrowserHacks.com] where I sent new hacks and test submissions for the site.

Here is the simplest of the ones I have created. It works, but will appear in earlier versions of Firefox if a flag has been set by the user. This does not really matter in most cases.

/* Firefox 22+ */

@supports (-moz-appearance:none) {
    .selector { property:value; } 
}

This slight change allows it to require version 22 and newer:

/* Firefox 22+ */

@supports (-moz-appearance:none) and (display:flex) {
    .selector { property:value; } 
}

This is the older way, the first way I found and tested to do this.

/* Firefox 22+ */

@supports (-moz-appearance:meterbar) and (display:flex) {
    .selector { property:value; } 
}

For those who like one-liners, here is a CSS hack I created for this purpose using pseudos:

/* Firefox 22+ */

_:-moz-tree-row(hover), _::-moz-range-progress, .selector { property:value; }
