This wider menu item spacing is a feature of the Firefox 89 "Proton" redesign. I can give you a quick short-term workaround, but a more durable solution will require more work.

Temporary Fix

For testing purposes, there is a preference to switch between new style and old style menus. It helps with the spacing, but might be a tad bit glitchy:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste browser.proton.contextmenus.enabled and pause while the list is filtered

(3) Double-click the preference to switch between true (new style) and false (old style)

In my test, the Bookmarks menu on the optional top Menu Bar was messed up in the existing window, but looked okay in a new window.

Longer Term Community Workaround

This involves setting up a userChrome.css file. The full instructions are in the following thread: https://support.mozilla.org/questions/1337841

I'm sure we'll refine that during the course of the month so when the temporary preference is removed, it will be airtight.

Thank you. I appreciate your time to provide an answer.

Thanks for the temp fix.

I really hope Firefox will give the option to change back. We're PC users here not mobile. The amount of websites that try to be "modern" by having HUGE buttons and lots of wasted space isn't what we're looking for. We're here to use a good browser for what we need to look for on the web. We don't turn on Firefox to admire how pretty the tabs look. My bookmarks folder before the update only goes down to half my monitor. After the update, it goes down 3/4 of the monitor.... not what we need
