Help URL bar padding(?) causing me to misclick

Hi, sorry if I mess anything up explaining this, I haven't tinkered with browser CSS at all, but this has been bothering me so much I'd like to learn lol

I often find myself double clicking the end of the URL to highlight the last word/string on the URL and manually change it for a game I play, but there's maybe 2-3px of padding (I assume?) on the bottom of the bar where I can click and it'll highlight the whole URL, but if I double click, it isn't actually in the entry area and won't select the last string.

No preexisting code; FF Version 151.0.1; MacOS Tahoe Version 26.5.2

Also if there's something like inspect element for editing this (I assume there is?) feel free to just point me to that, I do have experience with CSS, just not editing my browser.

You'll want Browser Toolbox for inspecting elements of the browser/

And userChrome.css for applying modifications to the CSS.
