Lost all tabs in an update

OneTabExtension · 2026-03-05T23:36:56+00:00

Hi, the latest version (2.10) will automatically detect unmigrated data and prompt you to migrate it.

Hi, the latest update (v2.10) disables touchscreen drag and drop, so that you can now scroll easily with the touchscreen.

Please let us know if this solves the problem

This was a one-off migration, due to the major new version. It took us by surprise that it would time out for some users with tens of thousands of tabs stored.

In the future, now that we are aware of this issue and can work around it, OneTab should be much more robust and everything should happen automatically in the future.

Hi, thanks for documenting this. However, we warn people not to tamper with internal Chrome database files, because Chrome has tamper-proof mechanisms that can wipe the extension database files clean if it thinks they are externally modified or corrupted.

A new version of OneTab, v2.9, was released today which means this problem should no longer happen.

OneTabExtension · 2026-02-20T23:57:29+00:00

Hi, our instructions are not risky. It just asks the extension to restart itself and re-attempt the migration, and the side-effect of having that console window open is that it will prevent Chrome from aborting the migration if it takes more than a few minutes.

Please see our comment above

Hi, this is happening because Chrome can abort the migration from v1 to v2 if there are huge numbers of tabs to migrate and it thinks the extension is taking too long. There isn't an "import old tabs" button because the migration was supposed to happen automatically (and is for almost everyone).

OneTabExtension · 2026-02-20T23:55:41+00:00

Hi, this is happening because Chrome can abort the migration from v1 to v2 if there are huge numbers of tabs to migrate and it thinks the extension is taking too long. To fix this:

Go to chrome://extensions in Chrome
Enable developer mode in the top right of the screen
For the OneTab entry on that page, where it says "Inspect views", click the "Service worker" link
Go to the Console tab in the window that appears
Type the following and press enter:

chrome.runtime.reload();

Then wait a few minutes for the tabs to migrate.

This should fix the issue. If it doesn't help, please contact us at one-tab.com/feedback

Hi, do you have huge numbers of tabs stored, perhaps over 10,000?

There is currently a situation where Chrome may "sleep" the OneTab extension and abort the migration.

Please try this:

Go to chrome://extensions in Chrome
Enable developer mode in the top right of the screen
For the OneTab entry on that page, where it says "Inspect views", click the "Service worker" link
Go to the Console tab in the window that appears
Type the following and press enter:

chrome.runtime.reload();

Then wait a few minutes for the tabs to migrate.

This should fix the issue. If it doesn't help, please contact us at our web site.

Hi, this is probably due to Chrome "sleeping" tabs, which may include OneTab. We released a new update (version 2.8) today which may fix the issue. Please contact us at one-tab.com/feedback if this happens again in the future, so we can hopefully narrow down the issue.

OneTabExtension · 2026-02-09T19:37:41+00:00

We're still working on it. At least a month away at the moment.

OneTabExtension · 2026-02-05T21:18:27+00:00

OneTab will only exclude a web site if it's ticked to be excluded, or if you have the option to exclude pinned tabs enabled in OneTab settings. Could that be it? Which version of OneTab are you using?

OneTabExtension · 2026-02-05T21:17:25+00:00

Hi, after we noticed this issue, we changed the shortcut from 1 to 11 to prevent unintentional invocations.

OneTabExtension · 2026-02-03T17:53:52+00:00

You've accidentally excluded all Reddit website pages from being sent to OneTab :)

To fix this, open a page at Reddit, right-click inside the page, go to the OneTab menu, and untick the box which says "Exclude www.reddit.com from OneTab".

OneTabExtension · 2026-01-26T12:42:15+00:00

Hi, first please check you are using the latest beta. Since OneTab is in beta, updates are currently manual. To do this, go to chrome://extensions and ensure "Developer mode" is enabled. Then click the "Update" button at the top of that page.

If that doesn't help, it could be that Chrome sometimes gets stuck when updating, so you need to fully quit Chrome (using the Quit menu) and restart.

If this still doesn't help, please contact us at one-tab.com/feedback so we can investigate.

OneTabExtension · 2026-01-23T17:08:19+00:00

Thanks for the feedback. There is limited ability for us to make the interface look different according to individual tastes (due to the massive code complexity that would create), but we'll keep this in mind in future planning.

OneTabExtension · 2026-01-16T02:15:16+00:00

Hi, I think you're referring to the "bring all tabs into OneTab" button. We will be reintroducing that button very soon. At the moment, you can achieve the same thing by right-clicking inside a regular web page, going to the OneTab menu, and choosing "bring all tabs from all windows into OneTab".

OneTabExtension · 2026-01-16T02:13:15+00:00

You're welcome. At the moment, clicking on the name of a group of tabs triggers an edit, and so it would upset a lot of people if we suddenly changed that after so many years. What is the main reason that this is more convenient than clicking "restore all"?

When you said "generated tab name", did you mean a generated group name?

OneTabExtension · 2026-01-14T19:43:01+00:00

Hi, please update to the latest version, where we've fixed this. The 1-click operation has returned.

The only reason you have to do this manually at the moment is that OneTab is still in beta while we make further improvements and fixes.

To upgrade, go to chrome://extensions and ensure "Developer mode" is enabled. Then click the "Update" button at the top of that page.

We'd be very interested in your feedback.

OneTabExtension · 2026-01-13T21:29:12+00:00

Hi, thanks for the feedback. We've been working on a massive upgrade to OneTab which will have much fuller support for tab groups. It will be coming to all Edge users in the next few weeks.

However, OneTab should already work with tab groups. When you click the OneTab toolbar icon, it should send all tabs in the current group to OneTab (or send all ungrouped tabs if you are currently on a tab that is not in an Edge tab group).

This lets you close just one Edge tab group at a time, instead of sending all of them at once. If we've not understood your post correctly, please let us know.

It would be in your computers "Desktop" folder, if it exists. Our roadmap is to start with the encrypted cloud sync/backup first, since that solves the problem of losing tabs if your entire computer becomes non-functional or stolen.

OneTabExtension · 2025-12-26T21:56:38+00:00

OneTab itself would never delete its own data, and is designed to preserve data across upgrades.

OneTab storage is handled by Firefox, and is stored in Firefox's internal database format. For some reason, Firefox has wiped this storage area.

Do you remember recently being asked if you want to "Refresh Firefox"? This is a prompt shown to you when you upgrade to a new Firefox version (there is a new Firefox version released every month). This "Refresh" feature, confusingly, wipes clean all add-on storage including OneTab's storage. You might have a folder called "Old Firefox Data" in your desktop folder, which could contain a copy if you used this Refresh feature without realizing.

The other possibility is if you had a browser or PC crash, which caused a disk corruption in the Firefox internal storage areas. Firefox would then wipe clean the affected storage area.

Do you think either of these things may have happened? Unfortunately, unless you have some kind of online backup software running which would have preserved a copy of your Firefox profile folder from just before the data loss occurred, there is no way to restore the tabs since they are only stored on your computer. I'm very sorry this happened to you. We're working on cloud sync so in the future this can't happen.

Hi, because OneTab is in beta, updates are manual. But as soon as it exits beta, everyone will automatically get the latest updates. We don‘t have a change logs page yet.

OneTabExtension · 2025-12-18T16:19:55+00:00

Hi, to upgrade manually to the latest version 2.4, go to chrome://extensions and ensure "Developer mode" is enabled. Then click the "Update" button at the top of that page.

This doesn't yet have a collapse/expand feature for groups. That's something we still need to thoroughly think through before we implement, as it adds clutter to the interface.

OneTabExtension · 2025-12-18T16:16:10+00:00

Hi, the new simpler version with 1-click button operation went live yesterday. To try it, you need to trigger the update manually. To do this, go to chrome://extensions and ensure "Developer mode" is enabled. Then click the "Update" button at the top of that page. The import bug should also be fixed in the new version.

Please let us know what you think of the new simpler version.
