It is possible to use code in userChrome.css to modify the appearance of this Edit This Bookmark doorhanger.

Add code to the userChrome.css file below the default @namespace line.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* Hide Giant Thumbnail and Favicon */
*|div#editBookmarkPanelInfoArea {display:none !important}

/* Set minimum height for the full folder panel */
#editBMPanel_folderTree {min-height:20em !important; min-width:27em !important}

(edited to cleanup spurious code)

It is not that difficult to create userChrome.css if you have never used it.

The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder.

• https://support.mozilla.org/en-US/kb/use-troubleshooting-information-page-fix-firefox

You can find this button under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in this folder (name is all lowercase). In the chrome folder you need to create a plain text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userChrome.css file as a plain text file.

In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt file extension and you end up with a file named userChrome.css.txt. To avoid this you need to make sure to select "All files" in the dialog to save the file in the text editor using "Save File as".

You need to close (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

• toolkit.legacyUserProfileCustomizations.stylesheets = true

Thank you for the quick reply. I think I did what you said. I created the chrome folder at the location shown by the png labeled Chrome Location.

It contains the code shown in the png labeled file contents.

I went to the config editor and set toolkit as shown in the toolkit png.

I closed Firefox and rebooted.

When I try to save a bookmark I get the same drop down as before. How do I change it size? There is no drag mark or other. See attached image.

I attached the pngs since the forum didn't seem to allow me to include that info in my reply.

Sorry, I forgot to remove a line between the two rules in the code I pasted in the reply.
Note that you can adjust the min-height and min-width property values to suit your needs.

/* Set minimum height for the full folder panel */
#editBMPanel_folderTree {min-height:20em !important; min-width:27em !important}

Thank you again. That works now. Apparently I can play with the numbers so I can make the window open to a predetermined size. That will work. I was expecting a drag icon to resize, but maybe this is better since I will always want it larger.

Two more questions while I have you here.

Since I made that change I have noticed a small new problem. I have set my homepage to google news. I also have "restore previous session" turned off.

If Google news open and I close it and reopen, Google news is there. But if I close it a second time and reopen and the tab is blank. It does not seem to matter how many other tabs are open.

The other question pertains to this forum. When I tried to reply to you, all of the items that I finally included as attached pngs were in the body of my message. I got a warning that I could not post links in a message. However, in your message above you have a URL with an https. I tried including it below and again got the warning. Do you need to precede the item with a special character?

In recent weeks, a number of users with Yahoo and Gmail as their home page mentioned that the page would be blank at startup. It would load if they clicked the Home button, or launched a new window, but for some reason did not load at startup. I haven't seen a diagnosis of this, whether it is an add-on issue, network issue, or something in Firefox. Clearing the cache seems to help at least for one or two cycles, but reloading the page bypassing the cache (Ctrl+Shift+r) would be faster.

There is an exception for moderators. The rest of us need to work around it for now. Adding a space after a dot in the text(dot)text pattern will allow the post to go through.

Thank you again. I just switched from Chrome (after years of use) to Firefox today, both because it is open source (and people like you reply) and because of security concerns that I have been reading regarding Chrome.

The startup page issue is a minor annoyance. I can live with hit. Hopefully it eventually gets worked.

Say I posted another item that I hadn't heard on, perhaps it landed elsewhere. I'm not sure if I'm breaking protocol by asking you as well, but clearly you are a savvy Firefox moderator. My question is perhaps a feature request, or maybe you know how to make it work no. I would like a one click or hot key combo to immediately access Other Bookmarks folder. If you put the Bookmarks icon on the toolbar you can click that and then click Other Bookmarks, but that is 2 clicks. In Chrome it is a single-click away and since I use if often I would like that in Firefox. See below for the image regarding the click sequence I mentioned above.

Hi eberger5, I think cor-el did most of the heavy lifting so far.

On this point --

-- the "Other Bookmarks" category is a bit of a latecomer, having been added in Firefox 4 as "Unsorted Bookmarks" and then renamed later. It's difficult to think of a way to assign a keyboard shortcut to it.

You could create a button for it on the Bookmarks Toolbar -- similar to Chrome's Bookmarks Bar -- but in that case, perhaps it would be more convenient to direct new bookmarks directly to the Bookmarks Toolbar, or the main body of the Bookmarks Menu? There is an add-on for that:

https://addons-mozilla-org/firefox/addon/default-bookmark-folder/

(You can triple-click that, then click Search Google..., or whichever search engine appears on your right-click context menu, while we can't do regular links.)

Or clickable:

• https://addons.mozilla.org/firefox/addon/default-bookmark-folder/

This should do it. Thank you.
