Right click on bookmark and go to properties to edit it. That what I just did to check.

Hmm, for some reason that row is hidden. In Firefox 64, you can "unhide" it using a custom style rule (no idea about future versions). I'll describe how to do that in more detail later in this post.

Here in support we work with the Firefox we have today, which involves built-in features, settings, and known workarounds. To advocate for changes in future versions of Firefox, you can use one or more of the following:

• Feedback: https://qsurvey.mozilla.com/s3/FirefoxInput/
• Discourse: https://discourse.mozilla.org/c/firefox-development
• Reddit: https://www.reddit.com/r/firefox/
• Twitter: https://twitter.com/firefox
• Facebook: https://www.facebook.com/Firefox

You can modify the appearance of the user interface by creating a userChrome.css file to apply custom style rules to Firefox's toolbar area.

Are you already familiar with userChrome.css from making other tweaks to Firefox's toolbar area? If you aren't, when you have 10 minutes to focus on it, here's how it works.

This assumes you do not already have a userChrome.css file. If you do already have a working userChrome.css file, you just need to add the rule under (A) to your file.

(A) Select and copy the following style rule code

/* Show URL in Bookmark Edit panel */
#editBMPanel_locationRow {
  visibility: visible !important;
}

/**** OPTIONAL EXTRAS ****/

/* Hide Giant Thumbnail and Favicon */
#editBookmarkPanelImage, 
*|div#editBookmarkPanelFaviconContainer {
  display: none !important;
}

/* Taller Folder Listbox */
#editBMPanel_folderTree {
  min-height: 350px !important; 
}

(B) Generate and download a userChrome.css file

Open the following page and paste the above rules into the editor, replacing the sample rule:

https://www.userchrome.org/download-userchrome-css.html

Then click "Generate CSS File" and save the userChrome.css file to your computer. (See first attached screenshot)

Use the downloads list on the toolbar to open the downloads folder directly to the new userChrome.css file. (See second attached screenshot)

Minimize that Windows Explorer window for later reference.

(C) Create a new chrome folder in your profile folder

The following article has the detailed steps for that (#1, #2, and I recommend #3)

https://www.userchrome.org/how-create-userchrome-css.html

I have videos for both Windows and Mac in case the text is not clear.

(D) Move the userChrome.css file you generated in Step B into the chrome folder you created in Step C

The next time you exit Firefox and start it up again, it should discover that file and apply the rules.

How do I edit the URL when bookmarking a page?

• v64 does not allow this anymore. WHY NOT? The default given URL, especially a long Amazon or eBay URL, is not necessarily the link I want to bookmark.

• This is basic, people. The URL should be visible and editable when the bookmark this page box appears.

Drives me crazy when 'good' features get axed.

• You can still edit the URL after you Bookmark it. It's more steps, but select from the Menu > Library > Bookmarks > 'Show All Bookmarks' (at bottom of List) and select 'Recently Bookmarked' and select the most recent Bookmark and edit the URL.

• Or, use Alt-B and select 'Recently Bookmarked'

Does anyone remember the last time a URL box was visible in the drop-down from the star icon? I looked through my folder of screenshots and as far back as Firefox 36 (attached), I don't see it.

Maybe it got hidden starting in Firefox 29 when the star moved out of the address bar onto the main toolbar?? A legacy extension in Firefox 29-56 could have "unhidden" it. In Firefox 57+, extensions can no longer make that kind of change to the user interface; a custom style rule is needed.

A search shows that it got changed in Firefox 41.
