I tried to do the problem and I couldn't, you probably have another extension that conflicts with the behavior. There are extensions that do the job of forcing a single URL to simulate a "standby" mode. If you can provide clear details of how the error occurs, including which addons you use, it will be easier to try to work around the problem so that you can enjoy this addon.

Thanks!

Thanks for the review. You can try disable "keep the tab that is active" in options.

Thanks for the review and for sharing your opinion. I understand your wish, but in addonsmozilla there are already other addons that do what you want, this addon I created to be automatic because it was something that didn't exist yet, apart from that it also differentiates containers. It is more for productivity in an automated way, especially for environments where this facilitation is required. I'm still very grateful.

it does not have controls, they are only configurations, the extension is different from others, the proposal is another one, the intention is that the addon to manage everything alone, based on some configurations made by you. But really about the texts I want to improve the description, is that the events of tabs are better known in the way described for those who understand the API, to pass some technical language to the understanding of other people is not always easy.

And by the way, the project is open-source, collaborations and text revisions are welcome on Github

Thanks! Unfortunately I think that is impossible, because events are triggered after the tab is opened, ie the control on the tabs only occurs after.

I believe that this is so to avoid problem like sending POST requisitions, that it would be impossible to do a check if there were the use of `form method="POST" target="_blank"`, this is how the internal API of firefox (WebExtension: https://developer.mozilla.org/en-US/Add-ons/WebExtensions) and other browsers works.

Thanks! I just need to improve the system to close the older tabs, I am currently using the IDs, but this does not seem to be accurate. I promise to improve the extension. [Update] New version (0.5.0) will soon be available, awaiting evaluation by the moderators.
