This is exactly what I've been looking for, thank you Lazyuki! Domain level titling does work!

I only use the feature to temporarily rename a tab, but that works flawlessly. It'd be nice to have a "Rename tab" option in the context menu for a tab. If that's available, I couldn't find it in the options.

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.

It would be awesome to allow to set title by just double clicking on the tab name, or within the tab context menu.

Don't work, tab title don't change.

Did it with "This time only" but this Add-on is not able to that for a specific url!! It just renames other tabs as well and then having several Tabs with the same name!

update: 20/09/2024. IT DOES NOT WORK AT ALL!!! WHY? BECAUSE THE CHANGE OF TITLES I MADE ONLY FOR A FEW PINNED TABS DOES NOT STAY FROM ONE SESSION TO THE NEXT!!!
I HAD SELECTED SET FOR THIS TAB!!!
THEREFORE, THIS ADDON IS COMPLETELY USELESS!!!

It works except for the New Tab when I want to rename this New Tab. Even when I select "Set for this tab", it is impossible to rename a particular New Tab with a different title!

頻繁に正規表現置換機能が止まってしまう不具合があるものの、これはとても便利。
　長ったらしいヤフオクのタイトルを、邪魔な部分だけ正規表現で取り除く事ができた。ドメイン単位での自動置換だけでなく、そのタブだけ名前を変える事ができるのもありがたい。
　正規表現はスペースを入れるとダメみたい。「\s」でも上手く行かず。`.`で代用した。

動作が途中で止まった場合はアドオンを一旦無効化し再起動する必要がある。ブラウザ再起動後、以前のプロファイルを読み込んだ場合には、ほぼ必ず機能停止している。

great addon, hope it keeps working with future firefox versions!

- Does exactly what you'd expect it to
- Doesn't randomly break
- You can rename a tab for a single browsing session or permanently for a given URL

Works well, and I like the option to pin the tab as a little globe icon.

However, if you accidentally refresh the ReTitle tab it reverts back to a full tab (taking up additional space on your toolbar) with no option to fix this except to close it and restart the extension.

A minor inconvenience that isn't worth a star off a free product, but is still worth mentioning.

Makes it way easier to see what I have open in BitBucket at a glance.

I absolutely love how tidy it lets me organize my tabs, although I couldn't get it to rename my open PDFs. I would love to see that implemented if possible (I realize I can rename the PDF, but I don't want to do that)

It looks that it's working, but after saving a tab in Wordpress, the new title is not saved :-(

Simply does not work for me in FF ver. 109: No R. clk option. But Tab Mix - Rename Tab does work, thank God.

Good extension but can't rename PDF tabs
