Quite useful in order to "rectify" some inadequate tab naming.
Would like if polling would be added to cope with changing titles (could have a user-specified interval and allow one to disable).
p.s. As it doesn't really follow the syntax (it's more a template), what's referred to as Regex could perhaps carry another name.

Does not work. Nothing happens after clicking the Update button. I did not restart the browser, so maybe that's the issue. I instead used a different extension (Tab ReTitle)

It lacks a crucial feature: I am going to the same URL but in different containers, and I need to be able to (permanently) rename them differently.
Also, is there no support site?

Very cool. To the author : when we click on the button to rename, please automatically "select all", so we just have to type.

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

This extension is great for a busy student! It does exactly what I wanted it to do. I have a couple suggestions.

1) It would be cool if when I opened a bookmark (that I renamed), the newly opened tab would keep the name I gave the bookmark. For example: I have bookmarks for my online math class that redirect to a login screen before I can get to the "Lesson" I bookmarked. When I click the bookmark and get to the login screen, the tab is still called "L30" or whatever I named the bookmark. After logging in, though, the tab is always just renamed to the name of the website, which is too vague to work with if I want multiple tabs open, so I often use this extension to rename the tabs to something more specific. It would be awesome if this extension could rename my tab back to "L30" when it detects that the site renamed it. Maybe this feature idea is too specific for most people's workflows, but it would help me personally if I could designate tabs so they are not renamed until I leave the website.

The way this would probably work is automatically renaming the tab after the website renames it.

However, if you're browsing reddit or Twitter or something like that, you want the tab name to change with what you're looking at, so this feature should be optional and only work when 1) opening a bookmark, and/or 2) you're on a site that you have chosen in settings to activate this feature. (e.g. I only want this to happen on wamap.org, the website where I do my math class)

2) Also, the icons for Firefox built-in features are specific to the feature and not just a screenshot like this one (for example: "Print" icon looks like a printer). Here's an idea for what a better icon may look like, based on the "Synced Tabs" icon: Go to: imgur dot com slash Y6mMXEv

Thanks for making this cool extension, dev! I hope I can make an extension this useful one day.

Thank you Anush.
Like others: Could it be possible to add a "Rename Tab Title" action to the context menu for right-click on the tab, please?

It's difficult to choose good custom shortcuts. Why? Some people use various browsers (Firefox/Chrome) or operating systems at the same time (at home, work...) and those have their own default shortcuts. Shortcuts are difficult to remember and not intuitive.

Wouldn't a context menu be lovely?

This is one of the (few) life changers, and one of the very few that bring so many smiles per day
I'd reached :-) :-) :-) before I got back to this page, so *****

Doesn't work with file:// pages, but straight editing of

Does the work. But a good feature, would be to completely replace the tab title (instead of appending).

Immediately I noticed it doesn't keep the tab name when using it. I'm using Firefox Browser 73.0.1 (64-bit)

This add-on can:
Access your data for all websites

To rename tabs why does it need to read data from all websites !

Dev please explain

Works perfectly!

Doesn't persist the title. As soon as I navigate somewhere else, the title changes by itself. Useless.

It works, thank you! Love the regex feature

Very nice addon, I like the feature that you can automatically rename tabs by a regular expression.

Two additions would make that addon even better:
1. An entry in the context menu of a tab
2. Re-use capturing groups from the RegExp inside the new title. Like "someurl.com/pages/(.*)" --> "Someurl, page $1"

I'm using Bunsen Helium Linux, derived from Debian 9 (Stretch).
Seems to work fine in Firefox Nightly Version 69.0a1 (2019-06-02) (64 bit)

Like others, I'd like it to be an option in the context menu (right mouse button).
The hotkey (Ctrl-Shift-E), is already being used to bring up Network Monitor, so it needs another key def.

This is a classic example of a tool that started out just to do a simple text change, then people wanted it to persist between sessions, then they wanted wildcards for multiple tab changes, etc., etc...
Anyway, its a good add-on; glad I found it.

NOT USEFUL

Nice add-on. I especially like the Regex entry type.
Need a way to import and export tab titles to/from a file in case of a Firefox re-install or migrating to a different computer.
