So I can use the thunderbird addon with gmail in a way? If I cannot its fine I have so many sites and things connected to the email I do not want to abandon it.
You can indeed utilize Thunderbird to fetch and even send mail with Gmail;

You can probably ignore the warning at the top of the page though about 'Newer' accounts not working (I just had to create a gmail account for a new client of mine back in december and have had no issues with using my older Thunderbird).
Unfortunately though the one addon I used to see used a lot for thunderbird with anti-spam stuff, looks like the author removed it unfortunately.
But at the very least thunderbird has it's own general anti-spam filter so it might even automatically detect and spam-folder natively.
All in all the only sure fire method you might have of near completely protecting yourself against spam is actually purchasing a literal anti-spam service to act in the middle, but I'm not sure of any that work at the individual/non-business level unfortunately :/
Beyond that spam is an unfortunate nature of email.
