Dude, I feel you. I spent hours trying to get Gmail proxy over Thunderbird to work.
One thing that helped was using a dedicated proxy for email traffic. Also, make sure your Thunderbird is updated to the latest version. Sometimes, older versions have bugs with proxy settings.
If all else fails, try this tool: [Tool Name]. It automates the whole process.
