Who each tool is for
Tab Manager Plus is the right tool the moment your browser has genuinely gotten away from you — eighty tabs spread across four windows, no clean way to find the one you need, and no appetite to close any of them because you’re not sure which ones still matter. That’s exactly the job it’s built for: a popup grid (open it with Ctrl+M) showing every open tab across every window as a searchable, filterable list, with duplicate detection, drag-to-move between windows, and enough view options (block, horizontal, vertical, dark mode) to make a hundred-tab mess legible again. It’s a real, mature project — version 6.0.0, open source under the MPLv2 license with its code public on GitHub, free with no paid tier or in-app purchases, and rated 4.7 out of 5 across roughly 1,100 reviews from around 200,000 users as of this check. For the specific problem of “I have too many tabs open right now and need to operate on them,” it’s a well-built answer, and it composes fine alongside a bookmark bar — the two operate on different layers entirely: open tabs versus saved links.
The name is worth being careful about, since it matters for trust, not just semantics. An earlier, unrelated Chrome extension called simply “Tab Manager” was removed from the Chrome Web Store after it was found injecting ads and behaving like adware. Tab Manager Plus is a separate project, written from scratch by different developers specifically in reaction to that malware-ridden original — its own store listing says so directly: “This version does NOT have any malware or hidden ads. We made this, because we were fed up with the previous version.” That’s a legitimate, safe successor with public source code, not a rebrand of the thing that got pulled. Worth knowing before dismissing the name on sight, and worth confirming again yourself if you’re reading this months later — extension ownership and safety records can change.
Where Tab Manager Plus doesn’t try to compete is persistence. Its core model is live tabs — close the window and, by default, whatever was in it is gone. There’s a beta feature to save and restore a window’s tabs from local storage, which is a genuine session backup, but it’s still a snapshot of a browsing state, not an individually filed link you can reach by name six months later. That’s precisely the gap Second Bookmark Bar fills: not the pile of tabs you have open today, but the small, known set of destinations you return to on purpose — the CRM tab, the client dashboard, the same handful of tools you’re in and out of dozens of times a day. Those don’t need a grid to search through; they need to already be filed somewhere visible, so reaching one doesn’t require scanning anything at all.
The honest concession here is genuinely straightforward, not a hedge: if you have a hundred tabs open right now and that’s your actual problem, use Tab Manager Plus — it’s free, safe, and built for exactly that. Second Bookmark Bar doesn’t touch open-tab chaos at all; it has nothing resembling a tab grid, and it isn’t trying to grow one.
Why the row is faster here, specifically
Neither tool is slow at what it does — that’s worth saying plainly instead of overclaiming. Tab Manager Plus is genuinely fast at its own job: open the popup, type a few letters, jump to the tab. The honest contrast isn’t speed, it’s what each tool is fast at. Tab Manager Plus makes open-tab chaos navigable; the row makes most of those tabs unnecessary in the first place. If a link is important enough to keep reaching, filing it once and never having to hunt for it among ninety other open tabs is a smaller cost, over and over, than searching a grid every time — even a well-built one.
The mechanical difference is where the interaction starts. Reaching something in Tab Manager Plus means opening the popup first — a keyboard shortcut or a click, then a grid to scan or a search box to type into, then a jump. That’s a fast three steps, but it’s three steps every single time, and it only works for tabs that are currently open; close the browser overnight and the grid is empty again unless you used the save/restore-windows backup. Second Bookmark Bar skips straight to the destination: the row is already visible above whatever page you’re on, so reaching a filed link is one click, not a popup-then-search. Auto-switch narrows it further — a rule you set once maps a site to a folder, and the bar can already be showing the right one before you look for it. That’s a fixed mapping the extension follows, not something it infers, worth stating plainly rather than oversold.
The save-time behavior compounds the gap over months, not just in the moment. Tab Manager Plus organizes whatever’s currently open; nothing about it decides in advance which of those tabs actually matter later, because that isn’t its job. Second Bookmark Bar’s Ctrl+Shift+A does the opposite: it takes every open tab in a window and files it straight into the active, visible folder on the bar as real Chrome bookmarks, at save time, not as a live grid you’ll have to re-scan tomorrow. A tab you didn’t file stays exactly what it was — an open tab, one crash away from gone unless you’d used the beta window-backup feature — while a bookmark, once filed, is permanent and instantly reachable the next time you need it. Same problem, two different defaults.
One honest boundary applies here the same way it does everywhere else on this site: the row 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, Tab Manager Plus’s popup and the row are on equal footing, since neither injects into them. Everywhere else, the two tools are simply solving different problems well: read more on how the paradigm question between bars, sidebars, and dashboards actually shakes out, or see the OneTab comparison for the closer contrast — a tool that also starts from open tabs, but collapses them into a list instead of a searchable grid. If your actual habit is saving every tab in a window rather than hunting through them live, one shortcut does the whole job in a single keystroke.
