Importing bookmarks from an old Firefox

[foxy]

Win 7
FF
Chrome 109.0.5414.120
Waterfox
-----------------------

I've been using Waterfox Classic, but it's getting outdated. Trying to switch from the very old Firefox 52.9esr to FF 115.3.1. I have 1200 bookmarks in the old one, and the new FF says it will import only from Chrome or IE. I know I can't re-use my old profile. Any idea how I can import my bookmarks?

Never mind. I copied the file places.sqlite. Now I need an extension that can make 3 rows of bookmark folders. None of my old extensions are any good.

Try this:

In WF Classic:
Bookmarks > Show All Bookmarks
Import and Backup > Backup...
The bookmarks should be saved to .json file
Click Save

In FF115.3.1ESR:
Bookmarks > Manage Bookmarks
Import and Backup > Backup...
Restore > Choose File...
Browse to the .json you created earlier
Click Open

I'm guessing you mean multiple lines in the Bookmarks Toolbar? I don't know of any current extensions that can do that, but you could try modifying your userchrome.css.

Note that you need to enable toolkit.legacyUserProfileCustomizations.stylesheets in about:config
about:config > toolkit.legacyUserProfileCustomizations.stylesheets > true

There is a "BOOKMARKS TOOLBAR - MULTIPLE LINES" section, but I haven't tried it myself. You'd need to remove the /* at the beginning of the line to enable it.

@import "./css/toolbars/bookmarks_toolbar_multiple_lines.css"; /**/

Thanks, Midknyte.
