If you don't like a certain feature, you can go ahead and download Firefox's source code, modify the files you want, and compile it yourself.

I don't use Linux, so I can't run source code! Windows's food is .exe files!

Note that "Close Tab" is what you see in the right-click context menu, so you can read this as Undo the "Close Tab" action and not reopen closed tab(s).

It's a little hard to describe, actually. The command will "re-open the last tab I closed" but if you already ran it once, it will "re-open the last tab I closed that I haven't already re-opened." Difficult to put into few words satisfactorily. 8-)

Please allow changing string names in next MF update.

We can't change such things here on the tech support forum. Mozilla has an input page for feature ideas and listens on social media:

• Input page: https://qsurvey.mozilla.com/s3/FirefoxInput/
• Twitter: https://twitter.com/firefox
• Facebook: https://www.facebook.com/Firefox
• Reddit: https://www.reddit.com/r/firefox/

What? I don't think you need to use tech support forum to allow changing string names in next MF (which means Mozilla Firefox) update.

I'll say it a different way: support forum volunteers -- the people with whom you are conversing in this thread -- can't change features in future versions of Firefox. Therefore, please submit your request where it will be seen by relevant people.

It would be possible to make string changes with a legacy extension, but you can no longer do this with a WebExtension (you can't overlay a chrome URI) and you can no longer get a legacy extension signed.
