It's very sad, but the extension does not allow set title "for this tab PERSISTENT ACROSS SESSIONS". In particular it is necessary to sign two different tabs with same url but different logic (for example 2 different mail containers). There is no way to specify site-specific information like domain or full url. Also missing is the ability to manually edit the already created url in the settings. Other than that, it's a handy and convenient extension.

Great!

This works well once I figured out how to do a Regex to remove a specific annoying phrase that Amazon inserts at the beginning of every page Title. I don't like that because it messes up the default name of my bookmarks.

Here's the regex I used: /AmazonSmile: (.{1,45}).*/$1/

This removes the literal phrase "AmazonSmile: " from the beginning of any page title on smile.amazon.com. It removes the first phrase and then inserts the rest of the title but only up to 45 characters in length. If the original title is longer, it truncates the rest. I found a Regex testing site that helped me figure this out. https://regex101.com/r/vMzP9d/6

The title is persistent when I restard Firefox, but it is NON PERSISTENT when I click on the tabs (which are now unloaded) : the tab reloads with it's original name, not the title i have modified before. Is there a way to fix this ? Thank!
If this can be fixed, then it's a great add-on :)

Please add the option to remove from the right click menu... Other than that, perfect.

Great Add-on, but it lacks a crucial feature: I am going to the same URL but in different containers, and I need to be able to (permanently) ReTitle them differently.
I posted an issue about this on GitHub, but no response. Has development stopped?

Come on, who on earth doesn't want this as a context menu on the tab itself? At least it seems to actually work.

I'm keeping a lot of similar tabs across reboots (organizing them using TreeStyleTabs). Tons of Slack, Mail client tabs, ... without meaningful title prefixes. I'm now using your extensions for assigning titles specific to URL prefix (thanks to your beta regex matching). My brain feels so relieved.
Kind of cumbersome to put in place, but the best option so far!
Would definitely appreciate the ability to modify/add regex more easily, but this is already so useful.
Thank you a lot!

Enhancement suggestion: wider pop-up

Wow. I was using 'Tab Mix - Rename Tab' before, but Tab ReTitle is far better.

Unlike 'Tab Mix - Rename Tab', I can assign a tab title to any URL. So that means I can open a new tab to that URL and it gets my custom title. I can also go to that URL within a tab and it gets my custom title. I can go Back or Forward to that URL within a tab and it gets my custom title. It's also persistent across sessions. So this completely solves the problem for me of how the YouTube history page just gets titled, "YouTube" instead of "History - YouTube".

Unlike 'Tab Mix - Rename Tab', the titles of YouTube videos aren't always automatically renamed to just 'YouTube". With 'Tab ReTitle', the video titles show as expected without me having to change any settings. It just stays out of Firefox's way (unlike 'Tab Mix - Rename Tab')!

There are a few other instances where the title never showed the way I wanted it to show, and 'Tab Mix - Rename Tab' couldn't help because it was just for that tab only and if I closed it, that was it, it was gone. Going to other pages in that tab meant the title doesn't change because I had simply renamed that tab. With Tab ReTitle, everything is exactly as it should be.

Fantastic.
(⬇optional, ty for your hard work):
ADD:
- right click tabs to rename them

Very easy to use gave important feature to set title for this Tab. I had same url where i needed different titles for automation which this plugin gave.

i love this extension i had lot of tabs open it helps to rename the specific tab

I need the regexp replacement so much.
Thank you.

The first add-on really retitle tabs.

Simple to use. It could be nice if you could remove the favicon too.
