It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.

Then use the Browse .... button below the Post a Reply text box to upload the screenshot.

The file was a screenshot 87 kbs 283x484 , a .png file. I made the image tiny it now is indecerable but it did load.

Getting back to my question.....Can the theme (drab Gray) of the bookmarks menu be changed?

So...Getting back to my question.....Can the theme (drab Gray) of the bookmarks menu be changed?

Anyone?

Maybe there's an add-on for this? But if not...

You can use custom style rules to modify the appearance of many parts of Firefox's user interface. Here's an example of a custom style rule applied using the Stylish extension's preview feature (see attached screen shot).

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#bookmarksMenuPopup, #bookmarksMenuPopup menupopup {
  -moz-appearance: none !important;
  background-color: rgb(255, 255, 204) !important; /* Pale yellow background*/
}
#bookmarksMenuPopup menu, #bookmarksMenuPopup menuitem {
  color: rgb(0, 0, 255) !important; /* Blue text */
  font-weight: bold !important; /* Bold text */  
}

I'm not saying that's pretty, but it's possible. You will need to be guided by your own color sense.

• Stylish: https://addons.mozilla.org/firefox/addon/stylish/ (after installing, click its "S" icon on the toolbar and create a blank style, then you can paste the rule and click Preview)

• If you don't want any more extensions, you can apply custom style rules to the UI by creating or editing a userChrome.css file.

• To get color codes, you can use: http://www.visibone.com/colorlab/ There also are sites that show colors which coordinate well together if you can't find a combination you like.

This thread shows how you can style the highlight bar which shows the current selection: How do I change the color used to highlight menu choices?
