Tips, insights, and stories about productivity and tab management
When the browser's own restore comes back empty, the tabs are often still on disk. Chrome keeps one old session in its profile folder and deletes it the second time you start the browser. Firefox keeps more, and Mozilla publishes the steps. Which file holds what, and the order that does not destroy it.

Ctrl+Shift+T feels like an unlimited undo. In Chrome it is a list of 25 closed things, fixed in the source code, where a sixty-tab window and a single tab each take one slot. Firefox keeps a different set of limits, and lets you change them.

Chrome draws your saved tab groups in the bookmarks bar, which makes them look like bookmarks. They are not bookmarks, they are not in your exported bookmarks file, and one unremarkable menu item deletes them from every device you are signed into.

A Chrome extension cannot read how much memory a tab is using, let alone free it. There is one call that unloads a tab, it is the same one Chrome's own Memory Saver makes, and everything else a RAM saver sells you is policy on top of it. Including the two words that turned the most popular one into malware.

Chrome's own documentation says local extension storage is cleared the moment you remove the extension. What that means for OneTab, Session Buddy, Tab Session Manager and TheTab, and the one thing that survives an uninstall when everything else does not.

The famous numbers - 40 percent of your productive time, 23 minutes to refocus - are a press-release extrapolation and a misquoted field study. Here is what task-switching research actually measured, and where an open browser tab fits.

Both promise to fix a full tab strip on Firefox, and they do it in opposite ways. OneTab closes every tab and replaces them with a list. Simple Tab Groups keeps every tab running and hides the ones you are not using, through a Firefox-only API Chrome does not have. Compared on memory, switching windows, and what survives a browser restart.

Both take a snapshot of every open window so a crash cannot cost you your tabs. Session Buddy is a polished, Chrome-only, closed app with a million users. Tab Session Manager is open source, runs on Firefox and Edge too, lets you set the auto-save interval, and can sync through your own Google Drive. Compared on storage, automation, what you can read, and how each one came through the Manifest V3 cutover.

Manifest V3 is three changes, not a hundred. Background pages became service workers that sleep after thirty seconds. The blocking network API became a rules list with a fixed ceiling, which is why the full uBlock Origin no longer runs on Chrome. And extensions can no longer load code from the web. Here is which of your extensions each change touches, and what Firefox, Brave and Edge decided to do instead.

Chrome shows you warnings, not permissions, and the two are different lists. More than forty permissions produce no line at all, one permission can hide another's line entirely, and the most alarming sentence in the box usually comes from the most ordinary thing an extension can ask for. Including our own extension's list, where eight of the thirteen permissions never reach the box.

Firefox shipped vertical tabs, tab groups, split view, local AI grouping and built-in Containers in eighteen months, and leaves nearly all of it switched off. Including the tab unloading that only runs on Windows, and the one thing Firefox still has no answer for.

Chrome frees memory in process-sized units, not tab-sized ones. Chromium's source says which of your tabs share a process, the six things that keep one running after you close its tab, and why your Task Manager will not show the drop either way.

Google describes the three Memory Saver levels as "a longer period of time" and never says how long. Chromium's source does: 6 hours, 4 hours, 2 hours, plus three more gates most tabs never pass.

Six tab managers compared on what actually matters: where your data lives, whether an account is required, how you get your tabs back out, and who each one suits. Including where OneTab is still the right answer.

Toby turns tabs into a visual workspace. OneTab crushes them into a list. Compared on data model, sync, privacy, speed, pricing and data loss risk, including where we tell you to use Toby instead of our own extension.

How to tell whether an extension actually stores your data locally, which permissions deserve a second look, and what the store listings do and do not tell you.

A single debugging session legitimately opens fifteen tabs, so the count is not the bug. The fix is session boundaries: a three-tab ceiling per task, a save before every context switch, and a dev profile with no path to Twitter.

A profile per client, three windows split between active work, reference and communication, and a shutdown routine that actually ends the day. Includes a paid placement from MoreLogin, marked in its own section.

What Chrome, Firefox, Edge, Vivaldi, Brave, Opera, Safari and Zen each give you for handling tabs, sourced and dated. Including Chrome's vertical tabs landing in April 2026, the Collections feature Edge deleted in June, and why Arc is now a warning rather than a pick.

Eleven extensions checked against their live store listings in August 2026, with the browsers each one actually runs on. Including which ad blocker works on Chrome now that uBlock Origin cannot, and which entry on this list went paid-only in March.
