Review by David White
by David White, 4 years ago
Somehow, with Firefox 80 the EBay Print Shipping Label page was placing up/down arrows in the numeric input fields for weight and dimensions rendering them unusable. I was able to find the offending CSS and figure out how to defeat it. Then I am very easily able to use this addon to over-ride the offending CSS. Freaking great! But I am really only a novice in all these matters. At least this prevents me having to switch to Chrome for this page/operation. Thanks!

    Nice plugin!

    Is it possible to get rid of the [CustomCSS Injector] Applied custom CSS. console.log() message?

    CSS inject is too late so page is changed after fully load

    Doesn't seem to work at all. No matter what css rule I put in the css box, it's always highlighted red (as in invalid data) when I click save. No errors, no feedback, no nothing. Even error console doesn't produce any output at all.

    Edit: Tested again after receiving developer's feedback and it seems to be working fine.

    The red border-colour appears only when applying custom CSS to URL or Domain. Your feedback however has given great insight into how it actually can be mistaken for an error. This feature has since been removed in the new version; along with a bug-fix and some small visual changes.

    It's also important to remember that the 'Mozzila.org' domain isn't affected by any custom CSS rules. This is because Mozilla explicitly doesn't let Firefox Add-ons alter the DOM on their domain. Make sure to test it out on another website!

    Thank you for checking out my Add-on!
