OneTab

Author(s):



***IMPORTANT: Read the bottom of this section for information on Firefox 57 and other version compatibility***

Whenever you find yourself with too many tabs, click the OneTab icon to convert all of your tabs into a list. When you need to access the tabs again, you can either restore them individually or all at once.

When your tabs are in the OneTab list, you will save memory and CPU utilization because you will have reduced the number of tabs open in your browser.

Privacy assurance

Information about your tabs are never transmitted or disclosed to either the OneTab developers or any other party. The only exception to this is if you intentionally click on our 'share as a web page' feature that allows you to upload your list of tabs into a web page in order to share them with others. Tabs are never shared unless you specifically use the 'share as a web page' button. We use Google's favicon generator to retrieve favicons for each domain in your list, but only the domain name is used and the full URL is never disclosed.

Additional Benefits

Depending on how many scripts are running inside your tabs, moving them to OneTab can also speed up your computer by reducing the CPU load. We have also had reports that this also contributes to your computer resuming from sleep more quickly.

FAQ: Why do I need OneTab, when I can just use my browser history?
A: Your browser history contains every site you've ever visited. OneTab is typically used to store just the smaller selection of open tabs you are not finished with yet - such as when you are mid way through researching a topic.

FAQ: Why do I need OneTab, when I can just use the "bookmark all tabs" browser feature?
A: OneTab is the quickest way, with only one click, to store all of your open tabs into a list. Once they are in your list, OneTab makes it much easier to scan over, delete, label and manage your list of saved tabs. There are also plenty of special options and features, such as the ability to exclude certain web sites, to remove duplicates, and to export/import tabs.

Pre-Firefox 55 Compatibility
If you are using an older version of Firefox, please ensure you are using OneTab version 1.17. Install it at this page: https://addons.mozilla.org/en-GB/firefox/addon/onetab/versions/

Firefox 57 Compatibility
If you have just upgraded to Firefox 57, make sure you have updated to the latest version of OneTab. To do this, go to the URL about:addons and then click the settings cog and choose "Check for updates".

If you have not used your browser in many weeks and have just upgraded to Firefox 57, you might be missing your OneTab data. This is because Firefox 57 has a new WebExtension storage format that is not compatible with older browser addons such as the older version of OneTab.

To recover older OneTab data, you need to downgrade to Firefox 56. The FF56 download is available here: https://ftp.mozilla.org/pub/firefox/releases/56.0.2/ and instructions are here: https://support.mozilla.org/en-US/kb/install-older-version-of-firefox . Then, while running Firefox version 56, install OneTab version 1.23 which is available here: https://addons.mozilla.org/en-GB/firefox/addon/onetab/versions/

When OneTab version 1.23 runs inside Firefox 56, this will migrate your data to a Firefox 57 compatible format. After you have installed and run OneTab version 1.23 on Firefox version 56, you can then upgrade to Firefox version 57 and install OneTab version 1.25 (or later) which is available here: https://addons.mozilla.org/en-GB/firefox/addon/onetab/versions/
