Firefox: Clearing “Recent Locations” in Bookmarks

Another day, another Firefox tip!

I’ve been using Firefox for years, and I’ve had one minor (but annoying) problem for a long time now: when you go to save a bookmark, there’s a handy list of previously used folders. That way you can quickly choose a folder to save the bookmark, rather than click through the entire folder hierarchy.

Problem is, this list stopped updating about 5 years ago.  The issue followed me through several versions of Firefox, on both desktop and laptop. I could save a hundred bookmarks in some other folder, but this list of recent folders has looked exactly as shown above since 2016 or 2017. And it was super annoying, since I mostly only use bookmarks as a session-saving type system these days. I save each Firefox window in a folder called “Sessions”… which I always had to manually click to, since the folders shown above never updated.

But yes, there is a way to fix this:

1) Open a new tab in Firefox and enter “about: config” (without quotes) into the address bar. Click “Accept the Risk and Continue” when prompted.

2) Type (or paste) “devtools.chrome.enabled” into the search box, and when it appears, double-click it to change the value from FALSE to TRUE. Close the tab when done.

3) Click the hamburger menu in the upper-right of he screen and click More Tools > Browser Console. A small window with a bunch of techo-gobbledygook will open:

4) Type (or paste) the following at the cursor on the bottom of this window:

await PlacesUtils.metadata.set(PlacesUIUtils.LAST_USED_FOLDERS_META_KEY,[]);

5) Restart Firefox. When you try to bookmark a page, the previous locations should now be empty, and will refill over time as you save to various folders.
