I thought that somewhere I read the Electron has no intrinsic mass, but instead gains it's mass via interaction with the Higg's field. But I found no reference to this in the electron's Wikipedia definition (although it is a long article, and I might have missed it). So what is true about the mass of the electron? And if the electron really has no intrinsic mass, is this also the case with other fundamental particles (i.e. Quarks)?
