I am not sure about the component here.
Just got to about:addons and navigate to 'Extensions' from the left navigation.

Now click on the gear icon at the right top corner of the page just before the search bar.

See if the result is similar to the attachment.

Definitely not what happened. it should stay still.

The element in question is here:

Which means its influenced by CSS applied to (among other things) `header-utils-btn`, you can see all the places that's referenced here:

For example:

So its likely you'll need to adjust the CSS in one of those files to fix the 1px jump.

I'm not sure if you've built Firefox before or not, if not the best place to start is here:

... and follow the instructions from there.

If you have any more questions please feel free to ping me and I'll see if I can help.

Hi, so i'm actually having some trouble pushing the changes that I have committed locally to MozReview, but this attachment shows what I have changed to prevent the button from moving down when it is clicked on my system.

If I can get more time to configure my hgrc files and stuff then hopefully I can push the code change to MozReview

I couldn't reproduce this on OS X, but I could on Windows and this patch fixes it for me. I'll set the bug for review for a peer. So you know for your next patch, you need to do this before check-in is allowed.

Alright thanks Andy, for future reference can you elaborate what steps I would need to do to check in the code myself?

To check in code for yourself you need to get level three access, the levels are discussed here:

Next step for most contributors is level one access so you can run tests on the mozilla testing infrastructure.
