OneTab Extension

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 up to 95% of memory because you will have reduced the number of tabs open in Google Chrome.

Privacy assurance

Information about your tabs are never transmitted or disclosed to the OneTab developers. 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.

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.

Baloo II (ID: 000000745ea70ea3) Voted 2 ★ - Updated 08/01/2024 Lack of support for multi-window environments still killing an otherwise great idea. Using it jumps you to a completely different desktop. Highly disruptive to the point of not being useful.

Mustafa Emre Koçak (ID: 000000fd70a65460) Voted 5 ★ - Updated 06/18/2024 Useful and practical thanks.

Liam (Kootranova1) (ID: 00000051d0f7d4a1) Voted 5 ★ - Updated 06/09/2024 Love this thing. Update june 9 2024, Now shows multiple Onetabs when i right click the extension, and i think it purged my saved tabs. Not happy.

Sharon Gilat (ID: 000000616ca6ff40) Voted 4 ★ - Updated 06/08/2024 Great for saving memory and productivity, however there is no auto backup and you might loose all info if the (chrom) browser needs to restart

Melissa (ID: 0000009dd049527b) Voted 3 ★ - Updated 06/03/2024 Could be more feature-rich but still my fav extension, good for AHDH ppl, got my ex using it. Yay for workflow! Edit: From 5 to 3 stars, would stop working often in past months until closing and reopening chrome, but that wouldn't have changed rating. But reinstalling chrome I lost over a year of tabs, older stuff not as important but many recent paused/in progress projects. I didn't realize my history wouldn't be like, tied to my chrome profile, because when I reinstalled chrome it automatically added all the extensions I had prior back to chrome. User error.. I should have made the important projects (dozens of tabs each) into webpages and messaged them to myself. I'm just gutted.
