Firefox bookmark tags: find saved pages across folders

Give related Firefox bookmarks the same tag, and you can find them together even when they live in different folders. If you save reference pages under several topics, a tag such as research gives you another way to find them when you cannot remember their titles.

Firefox also matches tags in address bar suggestions. Type * research to look among bookmarks, or + research to limit suggestions to tagged bookmarks. Put a space between the restriction character and the search term. These searches are useful shortcuts, but neither means “show only bookmarks whose tag is exactly research.” To inspect that tag’s membership, open Tags in the Library.

Add and browse tags

To tag an existing bookmark, open the page and click its bookmark star, then edit Tags. You can also open the Library with Ctrl+Shift+O on Windows or Command+Shift+O on Mac. The menu route is Bookmarks > Manage bookmarks. Select a bookmark there and edit Tags at the bottom of the window. The field’s down arrow lets you reuse an existing tag. Mozilla’s bookmark tags guide also shows how to browse tags in the Library’s left pane.

A page in Browser help and another in Web reference can both carry research while staying in their original folders. A read later tag can mark items in either folder, then be removed from an item you have finished while its research tag remains. Tags organize saved links; adding one does not save a copy of the page’s contents.

If the Tags field has disappeared and your existing bookmarks have no tags, add a first tag to a bookmark through the Library/menu route, then return to the bookmark editor. Mozilla documents this first-tag step for restoring the field.

Try a six-bookmark set

Save the tagged bookmarks practice file as an HTML file. If clicking opens a page of links, use your browser’s Save link as command on the link. The file contains six public reference URLs in two folders. The names below are editorial bookmark titles, so you can see how search behaves when a useful word is a tag rather than part of the title.

Bookmark	Folder	Tags
Firefox bookmark tags	Browser help	research, browser
Firefox address bar suggestions	Browser help	research, browser, read later
Firefox HTML import	Browser help	browser
MDN element reference	Web reference	research, html
MDN style reference	Web reference	research, css, read later
MDN accessible websites	Web reference	accessibility

In this set, Library > Tags > research contains four bookmarks: Firefox bookmark tags, Firefox address bar suggestions, MDN element reference, and MDN style reference. Tags > read later contains two: Firefox address bar suggestions and MDN style reference. Those are group memberships, not a prediction of address bar suggestion order.

To import the file, use the Library’s Import and Backup > Import Bookmarks from HTML command. Mozilla says HTML import adds bookmarks to the Bookmarks Menu and can duplicate ones you already have. If you are importing into a profile you care about, make a JSON backup first. You can instead open the six links above and tag bookmarks you choose to save. Mozilla’s HTML import instructions cover the import path.

Search without mistaking words for tags

Firefox’s address bar documentation lists several restriction characters. * restricts suggestions to bookmarks, while + restricts them to tagged bookmarks. You can put the character before or after the words, separated by a space. The # restriction matches a bookmark’s title or tags rather than its URL; $ matches URLs.

Try + research css as a way to look for the MDN style reference in the practice set. Try # css when you want css to match a title or tag. The bookmark’s editorial title says “style reference,” but its tag is css. For the precise set of bookmarks carrying research, use Library > Tags > research instead of interpreting a suggestion list as exact tag membership.

Search words are not a command to require two exact tags. A tagged bookmark could match research in its title and css in its URL, for example. Likewise, the practice file stores read later as one tag on two bookmarks, but typing + read later supplies two search words; it is not a documented exact-phrase query. You can use that query to look for those pages without assuming every suggestion carries the single read later tag.

Fix a missing page or a crowded search

If a page seems absent from a tag group, check Library > Tags first. Select the bookmark itself and inspect its Tags field before moving it to another folder. Its folder does not determine whether it belongs to research.

If the Library shows the bookmark but the address bar does not suggest it, open Settings, choose Search, and check the Bookmarks option in the Address Bar / Firefox Suggest section. The section’s name varies by region. If pressing Enter searches the web for your typed words, select the bookmark suggestion with the arrow keys or click it. Keep a space after a restriction character, as in * research.

When searches return too many loosely related pages, choose tags with stable meanings. For new bookmarks, a single-token tag such as read-later can be easier to type distinctly from two search words than read later. Both spellings can be tag names, and choosing the new spelling does not automatically rename an existing tag. To rename one topic, select its tag in the Library’s left pane, edit its name at the bottom, and inspect the resulting group. For example, web-research may be clearer than research if your collection also covers other kinds of research.

A bookmark keyword serves a different job: a dedicated shortcut such as home-docs opens one bookmark. A shared tag groups multiple bookmarks, including pages in different folders.

Source note: The practice file was imported, exported, and imported again with Firefox 141’s native bookmark tools in a separate test profile. All six saved URLs and their tag lists survived, including read later as one tag on two URLs. Menu paths and address bar searches follow Mozilla’s documentation; the dialog and suggestion UI were not exercised.
