broken links and UI elements

about:addons has two broken elements:

First, there is a search bar that says 'Find more addons: [Search addons.mozilla.org 🔎]'. The current functionality is to open a new tab with no content when the magnifying glass is clicked. The expected functionality should be either to grey out the search bar, remove it, or to make it correctly search addons.mozilla.org (the latter seems like it would make more sense, because it is not an unsolicited request and the UI even makes it clear where it will search).

Second, there is a button at the very bottom left of the screen that says 'Add-ons support'. Clicking the button does nothing. I'm not sure what this does on firefox, most likely links to some Mozilla page which says some useless disclaimer like, 'Mozilla is not responsible for the content of any addon, so ask the addon developer directly if you want support from them'. If that's the case, I think the best option would be to remove the button outright, or to grey it out. Otherwise, another possibility would be to restore the functionality of the button.

It appears to me that the relevant files to edit to remove the UI elements would be in toolkit/mozapps/extensions/content/ and the files are aboutaddons.js and aboutaddons.html. I am unsure exactly which change librewolf makes to remove the functionality from these elements though.
