Firefox Bookmark Keywords and Tags: Open Any Bookmark by Typing

A Firefox bookmark keyword opens the page when you type that word in the address bar and press Enter. Set it in the Library or in Edit Bookmark. Tags add more searchable words, and + before a search shows only tagged bookmarks.

Firefox Bookmark Keywords and Tags: Open Any Bookmark by Typing

How to use Firefox bookmark keywords

A bookmark keyword is a short word you attach to a bookmark. Type it in the address bar, press Enter, and Firefox opens that page. A keyword such as cal for your calendar or inv for an invoicing dashboard is faster than any search.

To add one, open the Library with Ctrl+Shift+O on Windows or Linux or Command+Shift+O on a Mac, select the bookmark and type in the Keyword field at the bottom of the window. Outside the Library, right-click the bookmark in the toolbar, menu or sidebar and choose Edit Bookmark.

Mozilla's bookmarks guide sets a few rules:

  • No spaces in a keyword.
  • It cannot start or end with ? * ^ $ % # +.
  • It cannot match a search engine's shortcut. If a search engine uses @g, a bookmark can use g but not @g.
  • Each keyword belongs to one bookmark. Give the same keyword to a second bookmark and Firefox moves it there.

Firefox bookmark keyword search with %s

Put %s in the bookmark's address, and the words you type after the keyword replace it. Mozilla's own example is the keyword mdn on https://developer.mozilla.org/search?q=%s. Typing mdn css border-radius in the address bar runs that search on the site.

This turns a site search into a shortcut. Run one search on the site, copy the results address, swap your search word for %s and save it as a bookmark with a keyword.

Older guides describe Smart keywords added by right-clicking a site's search box. Mozilla says that in Firefox version 140 that feature was replaced with custom search engines. For the same effect today, open Settings, then Search, and in the Search Shortcuts section click Add, paste the address with %s and give it a keyword.

How to use Firefox bookmark tags

Tags are extra words on a bookmark, and Firefox matches them when you type in the address bar. Add them in the Tags field when you click the star, or later in the Library. The arrow next to the Tags field lets you tick tags you already use, so spelling stays the same.

Two shortcuts narrow address bar results, according to Mozilla's address bar guide:

  • Type + and a space before your words to see only bookmarks you have tagged: + lisbon food.
  • Type # to see only matches where every word is in the title or a tag.

To browse by tag, open the Library and expand Tags on the left. Click a tag to see its bookmarks, or select it and type a new name at the bottom to rename it, as Mozilla's bookmark tags guide describes.

Tags field missing? Firefox hides it in the star window when you already have bookmarks and none of them use tags. Add one tag to any bookmark in the Library, and the field comes back. On phones, Mozilla's help for Firefox on Android and iOS covers names, addresses and folders and does not mention tags, so plan to add and search tags in Firefox on a computer.

For folders, A to Z sorting and the phone apps, see how to organize Firefox bookmarks. Before you retag or rename hundreds of links, back up your Firefox bookmarks.

Search bookmarks from the address bar

The address bar is fastest when you remember part of the page title, site name, or URL.

  1. Click the address bar.
  2. Type an asterisk, a space, and your search term: * sourdough.
  3. Inspect the bookmark-focused suggestions.

You can also try a domain such as nytimes, an author’s name, or one distinctive title word. Avoid typing a long question: Firefox matches information attached to the bookmark rather than answering questions about the page.

This method works less well when a saved title is vague, such as Home, Article, or Untitled.

Use Manage Bookmarks for a complete search

Open the Firefox Library with Ctrl+Shift+O on Windows or Linux or Command+Shift+O on a Mac. You can also open the application menu, select Bookmarks, and choose Manage Bookmarks.

Use the search box in the upper-right corner to search for:

  • A title word
  • Part of a URL
  • A tag you added earlier

Select All Bookmarks before searching if you want to cover the whole collection. Searching while one folder is selected may produce a narrower list. The Library keeps results in a table, making names and addresses easier to compare than the shorter address-bar suggestions.

Double-click a result to open it. From the Library you can also rename it, move it to a better folder, or remove it.

Search from the bookmarks sidebar

Open the sidebar with Ctrl+B on Windows or Linux. On a Mac, use the View menu if that shortcut is assigned elsewhere.

The sidebar combines a compact search field with the folder tree. It is convenient when you want saved pages beside the current tab or are working through a known group of recipes, product choices, or project references.

Use the sidebar to browse a known group. Use the Library for broader searches and reorganizing several results.

Why Firefox sometimes cannot find the page you mean

A bookmark stores a destination, but you may remember the reason you saved it: the recipe with miso or the guide that explained a particular error. Firefox may have only the original title, URL, folder, and any tags you supplied.

That creates a mismatch between the memory in your head and the text attached to the bookmark. Firefox also does not search the complete current contents of every bookmarked page. A changed or missing page, an unhelpful saved title, or a remembered sentence from the body may therefore produce no result.

Before deciding the bookmark is gone, try:

  • The site or domain
  • A person’s name
  • One unusual title word
  • A related tag
  • The likely folder
  • Recently Bookmarked in the Library

If whole folders are gone, not just hard to find, follow how to get back Firefox bookmarks that disappeared.

Add context to bookmarks you will need again

Rename an important bookmark so its title includes why you kept it. Model 4000 becomes easier to recover as Model 4000 quiet desk fan.

Tags can help with recurring subjects. Right-click a bookmark, choose Edit Bookmark, and add a few ordinary terms that match how you think. A recipe might use dinner, beans, and quick; a software guide might use the tool name and the error it solves.

Do not build an elaborate classification system. Tags help only when you can predict the words you will use later. Folders are best for clear projects or durable areas. Kitchen renovation is easier to revisit than a deep tree split by vendor, room, product type, and buying stage.

Why reliable return matters

People routinely let devices remember content while they remember where it was placed. A 2015 Kaspersky study found that 91 percent of US consumers depended on devices to remember, while 44 percent said their smartphone held almost everything they needed to know or recall.

That arrangement helps only when the outside memory is trustworthy. Saving is easy; returning is where systems often break. Material becomes scattered across places that do not communicate, leaving no single place to ask for it in natural words.

A reliable store frees mental room and helps you remember new things. An unreliable one creates anxiety because you cannot confidently withdraw what you deposited.

When a bookmark is not enough

Use Firefox when you can identify a page by title, site, folder, or tag. If you regularly remember saved material by meaning, keep a short note beside the link or use a tool built for that retrieval model.

dEssence is one option for saving products, articles, and videos, placing related items on boards, and asking questions about what you kept. You can send things to it through the Chrome extension, the Telegram bot or the web app at dessence.ai.

The test is simple: search using the words that naturally came to mind. If the page appears, the system works. If it does not, add that missing context while you still remember it.

Firefox bookmark keyword and tag questions

What is a keyword in a Firefox bookmark?

It is a short word that opens the bookmark when you type it in the address bar and press Enter. You set it in the Keyword field in the Library or in Edit Bookmark.

Can I use multiple keywords in Firefox bookmarks?

Each keyword points to one bookmark. If you give an existing keyword to another bookmark, Firefox reassigns it. For several searchable words on one bookmark, add tags.

Why are my Firefox bookmark tags missing?

The Tags field disappears from the star window when none of your bookmarks has a tag. Add a tag through the Library or Edit Bookmark and it returns. Your existing tags are listed under Tags in the Library.

How do I search only tagged bookmarks in Firefox?

Type +, a space and your words in the address bar. Firefox then shows only bookmarks you have tagged.
