When do you need a developer toolbar or a browser add-on for a mobile responsive test?

Generally speaking, if you don't need to show the mobile responsive test result to anyone, hence it doesn't have to be presentable or comprehensive, a developer toolbar or browser add-on will perfectly do. They're quite convenient responsiveness testers for ongoing front-end development, since you just grab the side of the panel and drag it left and right to change the responsive view. You shouldn't expect pixel perfect accuracy, but during the development stage you probably don't need to worry about the accuracy of the website responsiveness test. Basically, you just need to see that you've set up the layout and the responsive breakpoints correctly.

Some of the available Firefox add-ons are Default Responsive Design View by Aniket Kudale, L-Square Responsive Design Inspector by Jason M., FireBreak by Filip Johansson. Also, there are some nice add-ons for Chrome like Responsive Inspector by Piotr Walczyszn, Responsive-web-design by Dan Zajdband, Mobile/Responsive Web Design Tester by Gabe Hodges, Resizer.
