Rename Tab Title

Renames the Tab Title (Firefox 115+)

Click the icon on the ToolBar (or) use the shortcut Cmd/Ctrl + Shift+ E (can be customized
from chrome://extensions/shortcuts)
You'll get a popup, enter the new title
a)Click on Save (or) Press Enter to Save or Esc to close the popup without saving title
(closing the Popup without saving makes the title non persistent)
---
b) Click on "Edit All" in the popup to manage saved titles or use regex feature

In Urls section, select the URL from dropdown located at the bottom of the page
Edit the Title in textbox
Click on save (or) Press Enter to save the title.
Click on delete to delete the title.

In Regex section, add/update regex and the corresponding title and press "Save"
eg: /.*google.*/ matches all the websites which has the term google in the url,
/*/ matches all websites

*some websites keeps updating the title on some events (eg: gmail.com updates title whenever hangouts gets initialized and whenever someone pings) this addon doesn't work in such cases as i didn't add the polling. If have any workaround for this please do mention in the comments.. thanks

If you have any suggestion for shortcut.
Please mention it in the comments and the reason why it is better.
