Win7/Firefox 115 ESR.
I found I missed the extension on new installs.
Give a useful tab indication.
Would be nice if it prevented tab closure as well or remove the tab's X.

This rocks!

This one is a saver!

For other fellow reviewers, if you feel the feature of this one should be in the settings of out-of-the-box Firefox - vote https://connect.mozilla.org/t5/ideas/pinned-tab-should-not-all-the-url-to-change/idi-p/34397

Very useful.

Wish this were a native feature. But the add on is perfect instead! This completes pinned tabs in my opinion, as I can keep a dashboard open and click links to look deeper without having to click back or control click on each link

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

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

Youtubeにおいて、何か仕様変更があったのか、急に効かなくなった。
リロードやロックのやり直しをしても何故かトップページ（https://www.youtube.com/）だけは効かない。

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.
