running a remote browser to interface between a third party and the local browser; sending an image of the remote browser to the local browser and presenting an image of the local browser to the third party; selecting, on the remote browser, a local resource from a virtual representation of the local resource on the remote browser; and redirecting data from the selected local resource from the local browser to the remote browser. ## Claims ### Claim 1 A method for remote browsing, comprising: running a local browser instance on a local device; running a remote browser to interface between a third party and said local browser, wherein said third party is a web conferencing (WC) service and wherein the remote browser has no controlling access over resources on the local device except for capturing keystrokes and mouse or other cursor movements; sending an image of the remote browser to the local browser and presenting an image of said local browser to said third party; selecting, on said remote browser, a local resource from a virtual representation of said local resource on said remote browser, said virtual representation being generated on the remote browser from meta data provided by the local device, relating to said local resources to which the remote browser has no access; and redirecting data from said selected local resource from said local browser to said remote browser. ### Claim 2 (depends on 1) The method of claim 1, wherein said data is redirected from said local browser to said remote browser via direct peer-to-peer communication from within a browser. ### Claim 3 (depends on 2) The method of claim 2, wherein said direct peer-to-peer communication is facilitated by Web Real-Time Communication (WebRTC). ### Claim 4 (depends on 1) The method of claim 1, further comprising: generating a menu of local resources, on said remote browser, from which said virtual representation of said local resource is selected. ### Claim 5 (depends on 4) The method of claim 4, further comprising scanning an end-user device running said local browser to ascertain available local resources to populate said menu of local resources; wherein said scanning is performed continuously or on demand. ### Claim 6 (depends on 1) The method of claim 1, wherein a predetermined period after the local browser disconnects from the remote browser said remote browser is configured to terminate. ### Claim 7 (depends on 1) The method of claim 1, wherein said local resource is selected from the group including: a microphone, a webcam, a screen. ### Claim 8 (depends on 1) The method of claim 1, wherein said step of sending said image of the remote browser to the local browser is performed using WebRTC. ### Claim 9 (depends on 1) The method of claim 1, wherein said third party is a Remote Support service. ### Claim 10 (depends on 1) The method of claim 1, wherein the local browser connects to the remote browser via a proxy. ### Claim 11 (depends on 10) The method of claim 10, wherein the local browser downloads an agent from said proxy to enable communication with said remote browser. ### Claim 12 (depends on 10) The method of claim 10, wherein said data from said local resources is also redirected to said proxy. ### Claim 13 (depends on 12) The method of claim 12, wherein said data is manipulated by said agent and remote browser.
