Browser compatibility

BCD tables only load in the browser

  • In WebKit- and Blink-based Browsers, a non-standard and deprecated method ctx.setMiterLimit() is implemented in addition to this property.

Gecko-specific notes

  • Starting Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1), setting miterLimit to a negative value no longer throws an exception; instead, it properly ignores non-positive values.
