sRGB is the lowest common denominator and you never really know how it looks on other users' screens naturally. If you know that your viewer' use the latest browsers with color management support (enabled as it is off in FF to my knowledge by default) you can use others as well. But there is no guarantee again.
If you import any images they are normally in a certain colorspace, e.g. that of a camera. GEnerally Photoshop should not be set to change that on opening an file. Before you use an image on the web and it isn't sRGB, you need to convert it first to get a proper sRGB image under "Edit > Convert to color profile" (sRGB IEC61966-2.1) (reversed translated as my Photoshop is in German). Never just assign a color profile! Also if your images are CMYK before there might be a shift as CMYK is a much smaller color space than RGB.
If you then use the "save for web" Photoshop normally does not save meta data and color profiles to get the smallest size possible. If the image is in sRGB it should actually display normally.
