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.

Bisher alles bestens. Bin umgestiegen, da der alte 'keepass helper' nicht auf den aktuellen Stand gebracht wurde.
