Tab Control

A very simplistic add-on to position new tabs to the right of the current tab and activate the tab to the left when closing the current tab.

Easy to use, no need to configure anything.

No permissions required.

Inspired by the old Tab Control add-on by Angly Cat that is not supported by Firefox anymore.

Why does a wrong tab activate for a brief moment before the correct one does?

This seems to be a limitation of WebExtensions technology (or at least its implementation by Mozilla). The browser first opens a tab at its default position and only then it lets extensions know a new tab has opened and gives them a chance to do something. Same thing when a tab is closed. If anyone knows of a workaround to this issue, please let me know on Github!

Other known issues

The add-on conflicts with the built-in Switch to tab feature
Solved! Sometimes there could be a wrong tabs order when a lot are being open at the same time (eg by restoring a session or opening many tabs from bookmarks). Still having this one? Please let me know!

Are there any alternative add-ons?

Yes, there are:

Tab Open/Close Control by F. Kolbe, that includes a lot of options, but sadly activating tab to the left on close was not working properly and the author hasn't released any updates for several months, which has prompted me to write this add-on.
Open Tabs Next to Current by Sebastian Blask, that does exactly what it says in its name. Shame I haven't discovered his add-on before I went to lengths to implement my own.
Focus On Left Tab After Closing by e10s, that I have not tested yet, but it could work in conjunction with the previous add-on.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Control does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Tab Control has earned a fairly good reputation and likely can be trusted.
