Visual Studio .Net BHO App Updates

We have an app written in visual studio .net that works with Firefox and IE. We need several updates and code modifications done to the software app. Only bid if you... 1. Have knowledge of BHO's with IE, 7, 8, 9 2. Have knowledge of Firefox addons 3. Can complete the project by the deadline. What needs to be done? The modifications should be easy for someone with experience with BHO's 1. In the last version IE was working fine, since the last update our IE version doesn't seem to be working correctly we need this to work correctly (works fine in Firefox). Should be an easy fix. 2. Urls are sent to our server with some other data. We (when it was working correctly with IE) have an issue with IE where if they visit a https the user gets security warnings. We want this modified so if the user visits a https it calls the file on our server via https to get rid of these warnings (only happens in IE). 3. Verify the auto updater is coded correctly and works. 4. When sending the request to our server we need the software to generate a random number with the request so it is not cached. 5. Reduce exe size by cleaning up code. Must include source and compiled version for completion. If you can get this done on time and code well there will be much future work for you. Thanks for looking
