Chrome, Firefox adding extra <br>

Question

When I click view source, the HTML on my page is

but the page has a big gap above the table. When I Ctrl-Shift-I or view the source code in Chrome or Firefox's developer tools the HTML is

How could both browsers' view source be different than the source in the developer tools? Where are those <br>s from and how do I remove them?

Searching for <br> in the "view source" page says there are no instances in the HTML.

Good suggestions. Disabling all chrome extensions didn't work and there isn't any javascript that adds
's.

It turns out the HTML had <br /><br /> between the table rows:

<tr></tr>
<br /><br />
<tr></tr>

so the browsers must have rendered them before the table and changed them to <br>.
