For Firefox users
Best Firefox Bookmark Managers
Last updated October 14, 2026
Firefox already has a capable native bookmark manager, with folders and tags built in. For a lot of people that's enough. For others — once a collection grows into the hundreds or thousands, or spreads across deeply nested folders — finding and organizing what's already saved becomes the actual problem.
This guide compares Firefox's own bookmark manager against tools built specifically to work with it, and against separate cloud-based alternatives.

How they compare for Firefox users
As with any bookmark tool, "Where bookmarks live" is the row that matters most — it determines whether a tool works alongside Firefox's own bookmarks or replaces them with a separate library.
| Bookmash | Firefox native bookmarks | Raindrop.io | Sidebery | start.me | |
|---|---|---|---|---|---|
| Best for | Existing Firefox bookmarks, without migrating them | Simple bookmarking, no extra tool | A cloud library across browsers and devices | A tree-structured sidebar for tabs and bookmarks | A personalized start page |
| Where bookmarks live | Stay in Firefox (or Chrome) — read directly, nothing moved | Firefox's own local/synced bookmark store | Moved into Raindrop's own cloud library | Stay in Firefox's native bookmark store — Sidebery is a view on top of it | Moved into start.me's own account, organized into pages |
| Firefox integration | Extension reads and edits Firefox's native bookmarks directly | Is the browser — no add-on needed | Extension saves new items into Raindrop | Sidebar add-on built specifically for Firefox, reusing its bookmarks and tabs | Bookmarker extension saves new items into start.me; needs separate setup for a Firefox new-tab page |
| Also works on Chrome | Yes — same extension approach, same account | Not applicable | Yes | No — Sidebery is Firefox-only | Yes |
| Uses Firefox's folders / tags | Folders only — reads Firefox's folder structure; does not expose Firefox's bookmark tags | Yes — folders and tags | Folders; tags live inside Raindrop's own system instead of Firefox's | Tree view of Firefox's folder structure; tag support isn't listed among its features | Bookmarks reorganized into start.me pages instead of Firefox folders/tags |
| Search | Instant search-as-you-type over your existing titles, URLs and folders | Basic title/URL search, plus tag-based search | Search across saved bookmarks, collections, and (on Pro) full page text | Search within the sidebar's tabs and bookmarks panels | Search within pages and widgets built in start.me |
| Collaboration | No | No | Yes — shared collections with permissions | No | No |

Three ways to manage Firefox bookmarks
A. Firefox's native bookmark manager
Firefox stores bookmarks locally and syncs them across your own installs if you're signed into a Firefox Account. According to Mozilla's own documentation, Firefox supports folders plus tags, so a bookmark can be filed under more than one label — something Chrome's native manager doesn't offer. For a smaller collection, this is often genuinely enough.
B. Browser-integrated tools
Bookmash and Sidebery both work directly with the bookmarks already stored in Firefox, rather than moving them anywhere. Bookmash adds a searchable dashboard on top of your existing bookmarks (and also works the same way on Chrome); Sidebery adds a Firefox-only sidebar that displays your tabs and bookmarks as a tree. Neither requires an import step, and Firefox's bookmark store stays the single source of truth either way.
C. Cloud-based bookmark managers
Raindrop.io and start.me ask you to save or import your links into a system they run. In exchange, you typically get things a browser can't offer on its own: a library that follows you across browsers and devices, mobile apps, full-text search, archiving, or collaboration. The trade-off is that your bookmarks now live in a separate system, and migrating back out later means exporting and re-importing.
The tools, one by one
Firefox native bookmarks
Best for: simple bookmarking needs, no extra tool
Firefox's built-in bookmark manager supports folders and tags, syncs across your own signed-in devices, and includes basic search. It costs nothing and needs no extension.
Good fit if: your bookmark collection is small enough that folders and tags already work for you.
Probably not for you if: you have hundreds of bookmarks and struggle to find things, or you want faster, smarter search than the built-in one.
Bookmash
Best for: using your existing Firefox bookmarks (Chrome too)
Bookmash works directly with the bookmarks already stored in Firefox, through its Firefox extension. There's no import or migration step — Firefox stays the source of truth. On top of your existing bookmarks, Bookmash adds instant search-as-you-type, Collections, a "MyMash" favourites shortcut, grid and list views with sorting, and bookmark editing.
It does not maintain a separate server-side copy of your bookmarks, and it is not a cross-browser sync tool — Firefox and Chrome each keep their own native bookmark sets, and using Bookmash in both doesn't merge them into one remote store.
Good fit if: your bookmarks are already in Firefox and you just want them easier to find, organize and use — in a dashboard rather than a sidebar.
Probably not for you if: you want a single library that follows you across different browsers or devices independent of any one browser.
Raindrop.io
Best for: a mature cloud bookmark library across browsers and devices
Raindrop.io has a Firefox extension alongside its Chrome, Safari and Edge ones, and moves your bookmarks into its own cloud library rather than reading Firefox's native store. Its free plan includes unlimited bookmarks, collections and devices; the Pro plan (checked October 2026: around $3/month or $28/year) adds full-text search across saved pages, permanent page copies and library cleanup tools.
Good fit if: you want one bookmark library that works the same way across every browser and device you use, not just Firefox.
Probably not for you if: you'd rather keep using Firefox's own bookmarks instead of moving them into a separate system.
Sidebery
Best for: a tree-structured sidebar for tabs and bookmarks
Sidebery is a free, open-source Firefox sidebar extension that displays open tabs and bookmarks as a tree, with sorting, tab grouping, and the ability to highlight an already-open bookmark's tab instead of opening a duplicate. It works with Firefox's existing bookmarks directly rather than importing them anywhere — but, unlike Bookmash, it is Firefox-only and has no Chrome version, no mobile app, and no cloud sync of its own.
Good fit if: you want a persistent sidebar view of your tabs and bookmarks together in Firefox, and you don't need to use the same setup on Chrome.
Probably not for you if: you split your time between Firefox and Chrome, or you'd rather have a dedicated search dashboard than a sidebar.
start.me
Best for: a personalized start page built from bookmarks and widgets
start.me offers a Bookmarker browser extension for Firefox (as well as Chrome and Edge) that saves links into customizable pages alongside widgets for notes, tasks, RSS feeds and more. It has a free plan with a limited number of pages, and a paid Personal PRO plan (checked October 2026: around $25/year) for unlimited pages and widgets without ads.
Good fit if: you want a single home dashboard that combines bookmarks with widgets and feeds, not just a better bookmark manager.
Probably not for you if: you just want to keep using Firefox's own bookmarks, improved, rather than rebuilding them inside a start page.
How to choose a Firefox bookmark manager
- Stick with Firefox's own bookmarks if your collection is small and folders plus tags already work for you.
- Choose Bookmash if your bookmarks already live in Firefox (or Chrome) and you just want them easier to search, organize and use — without moving them anywhere.
- Choose Raindrop.io if you want one polished bookmark library across every browser and device, not only Firefox.
- Choose Sidebery if you want a Firefox-only sidebar that keeps tabs and bookmarks together in a tree view.
- Choose start.me if you want a personalized start page combining bookmarks, widgets and feeds, not just a bookmark manager.
Working with existing Firefox bookmarks, without migrating them
If you already have a large or deeply nested Firefox bookmark collection, the simplest path is often a tool that works with what's already there rather than asking you to rebuild it somewhere else. Bookmash and Sidebery both take this approach: they read and edit Firefox's native bookmark store directly, so installing them doesn't change where your bookmarks live or require an export/import step.
Bookmash specifically adds a searchable dashboard on top of those bookmarks — install the extension and your current Firefox bookmarks show up as they are, with instant search, Collections and MyMash layered on top.

Frequently Asked Questions
It depends on what's actually missing from Firefox's own bookmark manager for you. Firefox already supports folders and tags natively, so for light use it may be enough on its own. If you have a large, messy bookmark collection and want faster search and organization without leaving Firefox's own bookmark store, Bookmash or Sidebery are built around that. If you want a separate cloud-based library with mobile apps, collaboration or full-text search, Raindrop.io is a stronger fit. If you want a start page built from bookmarks and widgets, start.me is a different category of tool entirely.
For a modest number of bookmarks, often yes — Firefox supports folders and tags, and basic title/URL search, at no cost and with no extra extension. It tends to fall short once a collection grows into the hundreds or thousands, or gets deeply nested across folders, which is when a dedicated tool for searching and organizing what's already there (like Bookmash or Sidebery) or a separate bookmark service (like Raindrop.io) starts to help.
Sidebery is a free, open-source Firefox sidebar extension that displays tabs and bookmarks in a tree structure, with sorting and basic bookmark operations. It works directly with Firefox's existing bookmarks rather than replacing them, similar in spirit to Bookmash, but it is Firefox-only and centered on a sidebar/tree layout rather than a search-focused dashboard, and it doesn't work on Chrome.
Yes. Install the Bookmash Firefox extension and it works with the bookmarks already saved in Firefox — there's no import or migration step, and your Firefox bookmark folders and tags stay exactly as they are.
Yes, the same approach applies to both: Bookmash reads and edits the bookmarks already stored in whichever browser you're using, through its browser extension. Using Bookmash in both Chrome and Firefox doesn't merge their bookmarks into one shared library — each browser keeps its own native bookmark set, and Bookmash works with whichever one you have open.
No. Bookmash does not keep a server-side copy of your bookmarks. It accesses them through its Firefox extension, and Firefox's native bookmark store remains the source of truth. See how Bookmash handles your data for more detail.
Not always. Raindrop.io and start.me generally ask you to import or save bookmarks into a separate library or set of pages. Bookmash and Sidebery work differently: they use the bookmarks already stored in Firefox, so there is nothing to import or migrate.

No Bookmash-specific bookmark import. No separate bookmark database. Bookmash works with the Firefox bookmarks you already have.
