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.

work great for me

Hey, I might've found a solution for dynamically updated titles. The following code listens for changes of the 'document.title' object and allows you to execute code when it changes. I would send a PR, but it doesn't seem that you're on any public VCS platform.

new MutationObserver(function(mutations) {
console.log(mutations);
// overwrite the title here
}).observe(
document.querySelector('title'),
{
subtree: true,
characterData: true,
childList: true
}
);

Little regrettable. gmail.com don't updates title, but link Addon is update allways

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

If possible please make focusing tab switch to original title, the extension should hide infocus tabs titles only. Thank you.

Is it possible to use variable in title for regex definition?
for example:
Regex definition:
/.*google\.com.*/ -> title defining as: "[GOOGLE] - %title%"

give for url:
drive.google.com -> [GOOGLE] - My Drive
contacts.google.com -> [GOOGLE] - Google Contacts
calendar.google.com -> [GOOGLE] - Google Calendar

This is a great add on. But I've one more:

Feature request:
Please allow use to clean up the icon. (Reset to the default blank icon)

Thanks.

This does exactly what I want.
Rename Tabs to "Change" the title to make them easier to find.
Very easy to use.
