Update on 21/09/2024: it does not stay from one session of Firefox to the next, as my renamed pinned tabs had their changed titles all revert back to their previous titles at a new session of Firefox!!!

It works fine but one exception where it does not work is the following.

When I put a new tab on my firefox, I want to rename this new tab a particular name instead of new tab. I right-click and select rename but, for this particular case only, nothing shows up to allow me to attribute a new name to this new tab.

Thanks for the developer for this addon.

Almost perfect - it's a simple right click & rename as advertised. Only improvement would be to add option to persist after reload.

Does exactly what I want and requires less permissions then all the other extensions that does the same thing.

Right click tab and click rename, very easy
