I want to expand the size of the history panel

I just upgraded to v. 34 from v. 17.0.1. In the old version, I could open History as a full panel, and see the sites and dates in chronological order. Now, although I have the "View > By date and site" option selected, I see only the sites. Also, when I try to expand the size of the History panel by pausing the cursor over the edge, the double-arrow icon does nothing.

There is a minimum (min-width: 14em;) and maximum (max-width: 36em;) for the sidebar and you can't drag the resizer icon beyond that limit.

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 */

#sidebar { min-width:0px !important; max-width:none !important; }

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
  • Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
  • Use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
  • Paste the code in the userChrome.css file in the editor window
  • Make sure that the userChrome.css file starts with the default @namespace line
  • Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
    Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

Is this about the History Sidebar (Ctrl+H) or about the History Manager (Library)?

Try to open a new window in case there is a problem with the current window if toy use the sidebar.

You can check for problems with the places.sqlite database file in the Firefox profile folder.

History Sidebar (Ctrl+H). I solved it by choosing History > Show All History, meaning that I can see a full page of history with sites and dates. But why does the History Sidebar allow you to get a double-arrow icon when pausing the cursor along the edge, but not allow you to use it to change the size of the sidebar panel? Thanks.
