Thank you! This has solved having some sites only load on the left of the ultrawide screen. Also solves a sore neck!

Insanely good add-on for wide or large screens. Helps me keep content nice and centered. There are a small number of sites where a few elements are buggy, but I can't blame the dev. It works pretty great across tons of different sites.

I'm dependent on this add-on, I can't stand even going online without it!

Sites like .royalroad.com where you paste in your finished chapters are set up to be super annoying, tiny and in the 'middle" (more like way off to the right because it has a huge menu on the left side, just poor layout design ugg.) I love the site but wouldn't want to use it without this add-on!

Old websites like springhole (or whatever it's called) are even worse the text will span the entire computer monitor width! Often academic articles and such will also have things set up just to annoy readers, I swear. xD

Thank you for making this, all the other center page add-ons don't allow us to adjust things like this one does. I've been using this for years and rally want to donate, please add in a paypal.me or ko-fi, page. It'll make me happy to be able to help you.

Amazing extension mate, you're a life saver

This addon centers pages!

Crazy how basic functionality like this doesn't come integrated with every browser since 1997. Addon does what you think it does, love it.

Makes pages like Wikipedia that stretch end to end so much easier on the eyes. No more straining your eyes.

This is great for moving centered pages outs of the way when you use the video pop-out feature of firefox.

Solves a problem I've had for a while on sites like Wikipedia and on forum-like sites. Always nice to see a FOSS extension as well

This is exactly what I want.

works fine, thank you!

simple. useful. just what's needed. => genius

Thank you very much.
Your extension helped me! That's what I need.
So much the better which if you can provide some shotcut such as SHIFT+Middle mouse button.
and it can be keep left the content at the viewport.. haha perhapers I'm asking too much.
