Not sure why this isn't a thing, but it would have been sooo much more convenient to be able to RC on a tab and select RENAME there.

And also for the tab's name field to be blank when you open up the dialogue box, so you dont have to CTRL A and del each time

It works but lacks of usability. learn how to add URLs and patterns require some test as UI is pretty confusing. It is a promising addon

Doesn't work to rename tabs for PDF files, in Firefox 77.0.1 and Windows 10 version 1909

I dont see a place to add a new url. I want to add per site and not tabs .IT used to work in the past

Extension is working good but i do have a suggestion/Feature,
It should be able to handle domain names, currently it only renames individual tabs from a site.
e.g www.abc.com/xyz (renamed as) ----> AB
www.abc.com/qwerty (should also retain the name) ----> AB

Thanks & Cheers.

A good start, but a long way to go to truly make this extension useful. Need the ability to rename tabs based on rules (wildcards or complete URL's). Also, after renaming tab, it is not persistent.

Hopefully, I'll come back when the feature set is more mature like Tab Modifier (Chrome) or Tab Mix Plus was before the latest version of Firefox.

Appreciate the effort.

Firefox 55.0.2 with various extensions, multiprocess enabled. Screen recording and other information available on request. Find me in irc://irc.mozilla.org/#firefox or (if you use Matrix) https://riot.im/app/#/room/#mozilla_#firefox:matrix.org – thanks.

Rename Tab Title is one of my top ten extensions for Firefox 56.0.2 –

– less than five stars only because of the unresolved issue.

I have been using a different tab renaming add-on for many years but it stopped working with FF 55. What I loved about that one was when you renamed a tab, it was permanent regardless of if you navigated to a different URL within that tab. Is there a way to make the new name stick as I'm clicking on various links within the tab (which right now will make the chosen name disappear)? For example, it's pretty useless to name a tab "YOUTUBE" but have it disappear every time you click on a new video. I want the tab name to remain "YOUTUBE" no matter what. Any chance of adding this feature?

It would also be nice to just right-click the tab to rename it as suggested by the review before mine. The old add-on I used had that.
