Browser Makers To End RC4 Support In Early 2016
msm1267 writes: Google, Microsoft and Mozilla today announced they've settled on an early 2016 timeframe to permanently deprecate the shaky RC4 encryption algorithm in their respective browsers. Mozilla said Firefox's shut-off date will coincide with the release of Firefox 44 on Jan. 26. Google and Microsoft said that Chrome and Internet Explorer 11 (and Microsoft Edge) respectively will also do so in the January-February timeframe. Attacks against RC4 are growing increasingly practical, rendering the algorithm more untrustworthy by the day.
Assuming you aren't on a browser that is so old it doesn't support more secure algorithms (AES I believe is the one everyone should be using instead of RC4) then what will happen is that people still using RC4 certificates will switch to AES certificates and your browser will be more secure as a result.
