Who each tool is actually for
A switcher extension is the right pick for exactly one situation, and it’s worth stating plainly instead of arguing around it: if you want Chrome’s own native bookmarks bar to be the thing that changes — its exact rendering, its exact position, no injected row above or below it — a switcher is the only mechanism that does that, and it costs nothing. Bookmark Bar Switcher, Bookmark Switcher, and Bookmarks Bar Switcher all work the same underlying way: pick a different “bar,” and the extension backs up what’s currently sitting in Chrome’s native bar to a folder (Purtov’s calls it a “Bookmark Bars” directory; Wang’s uses a same-named folder inside Other Bookmarks), then moves the chosen folder’s contents into the now-empty native bar. You still only ever see one row, and it’s genuinely Chrome’s own bar the whole time — nothing about it looks or behaves like an extension is involved. For someone who has a strict “no injected UI” rule, or just prefers the native bar’s exact look, that’s a real and honest reason to pick a switcher over a second row. It’s also worth crediting Catiau-Tristant’s Bookmark Switcher specifically for a detail neither of the other two ships: bar names can carry emoji, which is a small but genuinely useful way to tell ”🏠 Home” from ”💼 Work” at a glance in a popup list.
The tradeoff for that native-bar purity is the swap itself, and it’s not hypothetical. Both Purtov’s and Wang’s own extension descriptions confirm the mechanism outright: every switch physically moves bookmarks between the visible bar and a backup folder. That’s a write operation on your bookmark tree every single time, and it shows up in how people actually describe using these tools. Reviews aggregated for Purtov’s extension include one describing it as working “like a dream until it deleted my entire work bookmarks folder,” and others calling it “a great idea, poorly executed,” with bars reported to mix up every few weeks. Wang’s listing is more direct about the specific failure mode: it acknowledges the extension “doesn’t work well across multiple devices,” with bookmarks reported mixed up or emptied when a switch happens while Chrome is mid-sync — a genuine race condition, not user error. Catiau-Tristant’s own listing doesn’t spell out the internal mechanism as precisely as the other two, but it carries the same tell: a stated disclaimer that the developer isn’t responsible if you lose bookmarks, with a recommendation to back up first. That’s not the kind of warning you’d need for a tool that only ever reads your bookmarks.
Staleness compounds the risk rather than offsetting it. Wang’s extension — the most-used of the three at roughly 10,000 users — hasn’t shipped an update since February 2019, over seven years before this page was checked. Purtov’s, last touched June 2024, is the most recently maintained of the group and still sits at more than two years without an update. Catiau-Tristant’s October 2024 release is the freshest, but also the smallest by user count and rating. None of that means any of the three is actively dangerous — nothing here suggests malware — but a bookmark-tree-writing mechanism with known sync-race complaints, sitting mostly unmaintained, is a real thing to weigh before trusting it with bookmarks you’d mind losing. One older multi-row attempt at this same category, Roomy Bookmarks Toolbar, appears to have gone further: every current reference to it routes to third-party mirror archives rather than a live Chrome Web Store page, and a community fork keeping it alive for Firefox/Waterfox is itself a sign the Chrome original didn’t survive.
Everyone else — anyone who wants “different bookmark sets depending on context” without a native-bar purity requirement — gets the same practical outcome from Second Bookmark Bar with none of the swap risk: two rows instead of one, automation the switchers don’t attempt, and nothing rewritten in the bookmark tree on every switch.
Why the row is faster here, specifically
The comparison here comes down to two of the same four pillars that make the row fast everywhere else, sharpened by how directly they contrast with what a switcher does. First, a switcher still costs a manual action on every context change — a click in the popup, or a keyboard shortcut you have to remember and trigger yourself, every single time you move between contexts. Auto-switch removes that step entirely: map a site to a folder once, in Settings, and the second row flips to the right folder automatically when you land on that site — a fixed rule you set, not something the extension infers or learns. None of the three switcher extensions has an equivalent; switching is always something you do, never something that happens because of where you already are.
Second, and this is the part a swap-based tool structurally can’t offer: the second row means you never lose sight of your base set while switched. A switcher shows you one bar at a time by design — whatever’s backed up is, for the moment, invisible. Second Bookmark Bar’s seven quick-switch slots are all reachable without touching a popup (Alt+1 through Alt+3 jump between the first three without the mouse), and because nothing is being swapped out of view, the folder you’re not currently looking at is one click away rather than one full swap-and-wait-for-it-to-settle away.
For anyone comparing this to Chrome’s own native tooling more broadly — tab groups shown on the bookmarks bar, the built-in reading list, or separate Chrome profiles for keeping work and personal bookmarks apart — the fuller breakdown of what ships natively lives in the adaptive bookmarks explainer, and the profile-based approach specifically is covered in separating work and personal bookmarks with Chrome profiles. One honest boundary worth repeating here, since “always there” is load-bearing to the whole row argument: Second Bookmark Bar is a script injected into normal web pages, so it doesn’t render on chrome:// pages, the Chrome Web Store, or the new-tab page — on those surfaces, whatever native tools Chrome gives you, switcher extension included, is the whole toolkit. Everywhere else, the difference holds: a switcher extension still asks you to do the switching, and does it by moving your bookmarks around; the row asks nothing, and moves nothing at all.
