OpenStreetMap
If you have version 35.0 of Firefox for Mac, kindly please update the browser to version 35.0.1 to resolve the glitchy-looking rendering issues when you drag the map on OpenStreetMap (Bug entry on Bugzilla).
Other operating systems should update anyway to keep ahead of any vulnerabilities.
Thanks!

Note that this only affects MacOS and not other builds of Firefox 35.

Firefox on Mac usually self updates if not disabled in Preferences -> Advanced -> Update It’s the default setting.

Oh good, was wondering if it was just my old machine playing up.
