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.

I don't see a menu option for Lock Tab with 66.0.3 on Ubuntu 18.04.2. However, the Auto-lock feature is working, and that's what I really needed. So, meets my needs, but not so great in general. I would love to see an option for "Links open in a new Window" rather than just a new tab.

Does not work in FF66...does nothing at all but put a padlock icon on the tab...and what would even be worse if it worked is that it unlocks when you reload a tab...hope the developer can fix these issues as there is no addon out there that will protect a tab...this functionality was provided in TMP.

FF60.6 ESR x64 - This addon is a nice attempt to mimick the Lock Tab feature from the old Tab Mix Plus extension, but it's sadly not persistent. When you open FF or reload a page, the lock goes away. Btw, the Protect Tab option would be good to have too.

Did not work for me at all. Icon remains grey always ... and the tabs I try to lock don't get locked.

The add-on is good up, the markings are not preserved, it would be good if you could refine Auto Lock. As only the main domain lock and not at the same time the supdomain.

With a name like "Tabloc" and a the description "Adds Lock Tab button", I am disappointed to find that this extension doesn't actually LOCK tabs so that that cannot be closed.

This extension only prevents the tab from being overwritten when you click a link inside the tab - it causes a new tab to be opened for that tab. That's great, but that's not what I was hoping for an extension with a name like "Tabloc".

"Pin Tab" doesn't work, either, because you can still close pinned tabs.

This extension does lock a tab and a link that would otherwise open in the same tab opens in a new tab. Nice. But if you refresh the tab, the lock goes away. A more minor event is opening a link from a locked tab makes the lock icon on the tab disappear even though the tab is still locked.

Nevertheless, I will keep it installed as the best we've got so far. Just have to remember to re-lock every time I refresh a locked tab.

I also tried the autolock feature. Does work, but it puts three lock icons on the tab that also disappear as described before. And any opened links from the same domain open locked with three lock icons!

Four stars as this function is so sorely needed, IMO, and am grateful to you for doing what you have done thus far. Any chance for working with the issues I described? Thanks!
