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?

FANTASTIC! Looks good, and everything you need is in the options (Default name type, and removing tags), and its compatible with other tab applications. Couldn't ask for more. Thanks!!

Hi. You told someone else you added the feature to rename tabs according to how our bookmarks are named, because of that I installed this addon but I don't see that option. Is it because that update to your addon hasn't been approved yet and you are still waiting on it?

I like your add-on. But I have one remark. In Options, what is the difference between 'Set for this tab' and 'Only exact match'? I tried both a bit, and Only exact match seems to work better.

Works as advertised, and the developer just added the option to have a one-time title. Now this add-on is truly excellent.
I have a suggestion. Is it possible that Tab Retitle shows, when available, your own title from your own bookmarks? As many people I have a lot of bookmarks and it would save time and effort if I would not have to retype those titles.
