Method for co-browsing a webpage (WP1) displayed in a window of a first web browser (BRW1) executed in a first terminal (T1), with at least one second web browser (BRW2) executed in a second terminal (T2), characterized in that it comprises: (A)- continuously obtaining (S23) with the second browser (BRW2) a video stream rendered in the first terminal (T1), said stream being continuously transmitted by the first terminal to the second terminal and comprising display data of the webpage (WP1) and reference data (REF) characteristic of a display zone of said webpage (WP1) in the window of the first browser, which zone is called the active zone (ZA) of the first browser, said reference data being graphically inserted into the active zone by the first browser; (B)- rendering (S24) the video stream in a rendering zone (ZR) included in a window of the second browser (BRW2); (C)- following detection (S25) of at least one action (ACT) triggered by a user (U2) of the second terminal (T2), which action is applied to at least one graphical element displayed inside the rendering zone (ZR), obtaining (S26, S27) information on the location of the action on the basis of an evaluation of the position of said graphical element with respect to a coordinate system associated with the active zone (ZA) of the first browser, said location information being determined depending on first position data relative to the reference data with respect to the rendering zone; (D)- transmitting (S28) to the first browser a message including a type of action associated with the detected action and said information on the location of the action; and (E)- applying (S29) said action to said webpage (WP1) in the window of the first browser depending on the content of said message. (A)- continuously obtaining (S23) with the second browser (BRW2) a video stream rendered in the first terminal (T1), said stream being continuously transmitted by the first terminal to the second terminal and comprising display data of the webpage (WP1) and reference data (REF) characteristic of a display zone of said webpage (WP1) in the window of the first browser, which zone is called the active zone (ZA) of the first browser, said reference data being graphically inserted into the active zone by the first browser; (B)- rendering (S24) the video stream in a rendering zone (ZR) included in a window of the second browser (BRW2); (C)- following detection (S25) of at least one action (ACT) triggered by a user (U2) of the second terminal (T2), which action is applied to at least one graphical element displayed inside the rendering zone (ZR), obtaining (S26, S27) information on the location of the action on the basis of an evaluation of the position of said graphical element with respect to a coordinate system associated with the active zone (ZA) of the first browser, said location information being determined depending on first position data relative to the reference data with respect to the rendering zone; (D)- transmitting (S28) to the first browser a message including a type of action associated with the detected action and said information on the location of the action; and (E)- applying (S29) said action to said webpage (WP1) in the window of the first browser depending on the content of said message. <EOS>
