Are chrome URLs: chrome://browser/content/places/places.xul, et al, broken in Firefox 73

I have bookmarked the 'Library' using the chrome URL: chrome://browser/content/places/places.xul, for the purpose of opening the library in a new tab. This, and other chrome urls such as: chrome://browser/content/bookmarks/bookmarksManager.xul, no longer work, apparently since Firefox updated to 73 or 73.0.1.

Now when clicking the bookmark, I get the error: File Not Found. Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/browser/content/browser/bookmarks/bookmarksManager.xul.

The omni file in the Programs folder now is: omni.ja, not omni.jar.

Was the omni file made obsolete or changed? Will this be addressed in the next update?

How do I workaround this to maintain my bookmark for the library and other bookmarks using chrome urls as referenced at: http://kb.mozillazine.org/Chrome_URLs?

Hello skippdiddly,

The "xul" changed to "xhtml" with the latest update.

So, now you'll have to enter this URL in the address bar :

chrome://browser/content/places/places.xhtml

The same goes for these :

chrome://browser/content/places/bookmarksSidebar.xhtml

chrome://browser/content/places/historySidebar.xhtml

Does that work for you ?

Note that we have seen reports that making changes to bookmarks when you open places.xhtml in a tab isn't working properly, so make sure to check this.

You could bookmark the URL (just a thought .... )

So far the change to Library using chrome://browser/content/places/places.xhtml is working fine. I'll post any issues, if that should change.
