Request for ability to expand list of "leftover redirector tabs to automatically close"

[saxhouse]

If you use the Temporary Containers add-on, you probably appreciate the "Automatically close leftover redirector tabs after two seconds" feature

in the Advanced options menu.

However, it strikes me as an odd design choice for users not to be able to customize and add other domains (ie google) to the list of sites that use redirector links. Currently the feature only supports Twitter, mozaws.net (Mozilla owned) and Slack...which is unnecessarily restrictive.

The add-on should be patched so it can support redirector url domains supplied by the user.

But I will settle for a custom Temporary Containers script
to run instead if someone could help me write it.
