Thank you for the Tabloc! Tabloc is a very necessary add-on.
Please add the ability to save the "enable" value for all open tabs. And so that this value is saved when you restart firefox.Thanks!

Works great, including the regex feature (.*youtube.*watch.* for example)

Auto-Lock with explicit URLS (not regexes) does exactly what I need.

Does not work if you reload the tab. + Auto-Lock doesn`t work either.

各タブの右クリックで表示されるメニュー内でも操作できたらボタン追加しなくて済むのにと思った。

Good, but I'd also add a {FOREVER} feature so that the locked tab remains on the browser forever, even when exiting and then opening a new browser. Also add a {STAY PUT} feature where if the locked tab gets reloaded, it remains locked! Thanks

Just discovered this add-on as I needed this function and wondered - hmm - is there an add-on for this? And yes, there was. Thank you, Asukaze. Some feedback:
(1) the icon is hard to see on dark background theme in Firefox
(2) when I lock a tab, the lock icon is not persistent - i'd like the lock icon to persist so I remember it is locked

Does what it says. Nice and minimalist!

概ね非常に満足なのですが、唯一、一番右に来るタブだけ（最後に開かれるタブ）ロック設定しても、Firefoxを再起動するとロックが外れてしまうのが残念ポイント。

Work but when a locked page is refreshed the settings are lost

Do just what it says. Thank you !

an amazing add-on.
works like a charm.
thanks a lot, good Sir

edit:
i wish i could pin "new tab" also

How does this work in preventing the accidental deletion of a tab? Thanks.

Makes your browser behave exactly how browsers should have been behaving since tabs were invented. It is going to be *SO FREAKING NICE* to not have to middle-click every single freaking link on the entire freaking internet.

But, given that this just brings the world into sanity, it's really annoying to get that padlock emoji in my tab titles. It serves literally no purpose; it's like Homer's “everything's okay” alarm.

It forgots the "locked" setting very soon, even before browser restart. After browser restart it always forgots the locked state.

this extension need a shortcut having to move mouse each time to click the icon is too much of a pain and inefficient.

I wanted an app to really lock my tab, I still can close it with the X or with CTRL+W. I wanna protect it from accident closing...

Outstanding, does what you expect and even allows for in-page frame links which is essential for many web-based apps.
(updated) Would like to have a shortcut key to toggle temporarily it off on some sites. For example- in Amazon product question\answers, the links will not open to a new page. A key click combination would be perfect i.e. Ctrl-Click.
