Great addon, but I have a feature request: would it be possible to make it work with pages that request Basic authentication?
Right now the only way to make it work is canceling the auth request so that the window title gets modified, and then refreshing the page to make the auth request come up again.
Thank you.

Doesn't need permission "access to your data on all websites" like many others. But doesn't show the custom url on sites with basic authentication - only after basic authentication is canceled and site reloaded the proper window title is shown.

Do you think you could add Thunderbird support the way that this addon did? https://addons.thunderbird.net/en-US/thunderbird/addon/keepass-helper/

That one no longer works with the latest Thunderbird.

It used to add the current email account's ID to the "Mail Server Password Required" popups so that KeePass could enter the password.

Other than that, works great on Firefox.

I second the previous comment. Current version effectively obscures the title information. Also it would be better to allow the user to specify a regexp, so the extension could modify only matching URLs.

Very good addon. The feature to show the port number in URL is very useful.

Would be great if there was an option to write the url after the title and not before...
You say in the preceding comment that is is not possible, but some other webextensions addon are doing it:
https://addons.mozilla.org/en-US/firefox/addon/custom-titlebar-text/
https://addons.mozilla.org/en-US/firefox/addon/hostname-in-title/
https://addons.mozilla.org/en-US/firefox/addon/url-in-title/

But for these extensions, if we drag & drop the Firefox url in Windows Explorer, the url is contained in the created shortcut filename, which is useless and very bad (filenames are too long). I don't know if this is the consequence.

Thanks for making this add-on! This is the only "URL in titlebar" extension that doesn't affect the title of the tab. I wish the extension could put the URL at the end of the window title, instead of the beginning. Unfortunately, while Mozilla provides a titlePreface property, there does not seem to be an analogous property for a suffix. Is there a bug filed to request this capability for WebExtensions?

I would like to suggest the developer implement a workaround for a bug in Firefox ( https://bugzilla.mozilla.org/show_bug.cgi?id=1402399 ) that prevents the titlebar URL from being updated when switching to a blank tab. This causes the URL of another tab remains visible indefinitely. The bug can be worked around by setting the titlePreface to a single space (' ') instead of an empty string ('').

Thanks again! This makes KeepassXC usable again.
