OneTab is one of the well-known browser extensions that collapses all open tabs with one click and saves them as a simple list. From ONeTab, you can save this list as a web page, share it with your friends, or restore them all. But if this is your first time using it, all of these features can feel overwhelming. Don't worry, here is a step-by-step guide on how to use OneTab effectively.

Before you begin

The reason I recommend OneTab over another card manager is the memory usage. I have opened a lot of YouTube tabs that consume more than 1GB of memory, out of my 4GB of RAM. After enabling OneTab, it dropped to almost 44MB, which is a useful drop in memory usage on its own.

I know you already know this, but for those of you who don't, just go to Google and search for OneTab or click here. Then click Add to Chrome. It will automatically be added to Chrome.

You can also see the icon at the top right. To view the quick check or explore the settings panel, right-click on the icon.

It's clean and kind of reminds me of Windows XP. Above it shows the exact number of cards that have been condensed. Just below it shows the date and time of the creation of that specific card. Below you can see options like restore, delete, share as a webpage, etc.

Therefore, all the possible functions that you want to use are right in front of you. Some other options, such as settings, are present at the top right of the page, so there is no intrusion with the main content.

Features
Simply OneTab takes all your cards, condenses them, and puts them into one card, grouping them all. Then you tap and you get a window with a list of pages spread over several tabs.

Basics
This will help you condense all the tabs into one space so that you can expand them all at once by just clicking Restore All. This brings you to the same space before clicking on it. Another quick option is Remove All, which removes all the tabs that you have compressed as soon as you click on them. Although OneTab prompts you to remove tabs first, I suggest you be careful.

Share As Web Page
This is a useful tool when you want to share one group of tabs at a time, as a single accessible web page. By simply clicking on a group, you can send all the cards in that space as a link to anyone. There is also an added barcode that can open the web page while scanning. You, therefore, have the option of a static link and a QCR code.

Delete: I guess this is the function I use the most. It allows me to share all related web pages in one tab. It helps me when writing or reading about a specific topic because I can easily group and tag them.

Group functionality
Grouping all the tabs into one was one thing, but tagging them in groups is just something that helps me be more efficient. I easily name groups and keep them organized.

Get all the basic features separated by groups. But what if you want to add news cards?
As simple as it sounds, you can combine and drag items from one group to another.

Each new tab you close will form a new group that you can rename or add to another group from One Tab.

In addition, you can also lock the group which disables the delete function, which makes it an additional security feature, although I have used it very little.
