This extension removes the URL intercept/redirect on Gmail and many other sites:

This one handles the other situation, tracking parameters added to the URL that are intentionally passed to the target site:

Thanks for the link. I just spent a few minutes looking at this extention’s creator’s github activity. Installing this will be my first todo list activity whenever I first use my laptop today.

That redirect always bugged me.

EDIT: I just noticed on the install page "This is not a Recommended Extension. Make sure you trust it before installing.Learn more" which is annoying.

ClearURLs by Kevin R. is recommended by Mozilla, so maybe that's a better option:
