Firefox addon

Greetins, I need a Mozilla Firefox 2.x addon that: 1) is going to scroll down/up unlimited times according to time period option for the selected tab(s). This time period will be the length of time for each scrolling up to bottom of the web page. Scrolling of the page will be automated so no user interaction will be needed. When bottom of the page is reached, according to option, addon scroll will return to top of page or scroll backwards. Time period could be set independently for tabs. (not just a 10000ms. scroll time for all open tabs.) Time period unit will be miliseconds. Therefore, a web page could be available to auto-scroll top to bottom for 1 sec, unlimited times without user interaction. (A limited sample of this job can be seen with autoscroll capability of IE7Pro addon on Internet Explorer) 2) is going to let me switch between tabs for independent time limits without user interaction after set. e.g. 1 sec for first tab, switch to second tab, stay 5 secs., switch to third tab, stay 10 secs., switch to first tab,... But this will not prevent first property. On the other hand it is not important that background tabs are scrolled or not; that coder can decide background tabs are whether scrolled. (A limited sample addon can be seen with Auto Toggle Tabs addon on firefox 1.5) Summary: -Firefox 2.x support is a must. -Addon(s) could be invoked seperately. However above expressed properties should be considered. -It's not a must that invocations are coded newly. I just need this(these) addon(s). You can find written one apart. However, coder should present all the needed properties anyway. -As well as xpi, sourcecode is a must. But coder can decide license type for other rights but usage rights. Thank you for your intention. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) License type can be decided by the coder, despite I prefer GPL. But all usage rights without exception belongs to bid requester (me). ## Platform -Platform independent (Linux, Windows are must; other os supports depends on coder) -Firefox 2.x
