It does what it says for the most part, but for me the new tab title doesn't persist between sessions like it says. When I rename a tab and chose the "Set for this tab" option, and then close and reopen firefox, the tab title has reverted back to it's original value. If the renamed tab title would actually persist between Firefox sessions this add-on would be very useful for me. I'm gonna try some tab stickies add-ons instead for now.

Titles are lost on tab reload.

I really liked this add-on. It helped me get organized and worked seamlessly.

Recently, I took it upon myself to review my extension accesses and I was disappointed to see this extension requires "Access to all website data".

I wish they would just use the tab title and not require this overarching permission. It may be a legacy thing - and I hope they change it - because I really do want to use it again.

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 :)

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?

Very good work so far -- however, to be truly useful, it needs to allow us to *prepend* something, not just replace it completely. I'm a developer using this across multiple environments for the same product (local, dev, QA, staging, production.) I would love to prepend "QA - nnnn", etc. Maybe you can make this an option, or at least allow us to use {0}-style replacement for the original title?
