Excellent little extension, helps you avoid closing radio tabs :). Still, a couple of new features would make it awesome:
1) prevent reload
2) dialog popup when browser closing if any protected/locked tabs exist.

worx good so far, but the option "prevent goBack/goForward" doesn't work with Tab History Menu 2.1.1 (https://addons.mozilla.org/en-US/firefox/addon/tab-history-menu/).
activated "prevent goBack/goForward" but still CAN go back or forwards by just clicking tab and then select.
5 Stars if this could be fixed.

Great to see a replacement for PermaTabs Mod working in new versions of Firefox (10 as I write it).

This probably is the future of Permatab Lock.
Excellent and easy, Sometimes, Forbidden The tabs, I hope the best for this !

Tabloc is great but no work @ FF5.0 , Ok in FF4 & 4.0.1

I love Tab-Loc functions but its not compatible for FireFox 4.0. One review is get the Pin-Tab confused with Tab-Loc two different functions. I went back to FireFox 3.6.16 until Tab-Loc is upgraded. Thank you for a great add-on!

The newest version is not yet reviewed but you can find it using the View All Versions link below.

The Tabloc icon is not visible while a tab is pinned as an App Tab, but it does work correctly, and the icon is visible again if the App Tab is unpinned. That's the way App Tabs work.

i used this before =D great addon for those vid sites that load slow, when i was going through a bizzaro watching everything phase. =))
suggestion: an auto lock feature, black/white listing for sites. no extra click =)
reg exp supported would be sweet =))

Very nice plugin.

The only downside is that, when you click a link on a locked tab, the new created tab doesn't get activated.

If you could fix that, it would be 5 stars for me.

Anyway, it's a great plugin

Es muy util , muchas veces trabajamos con varias pestañas abiertas y con este agregado, es muy seguro mantener nuestras pestañas mas importantes bloqueadas y protegidas...
Lo recomiendo al 100%.
Saludos.

Lock+Protect = Excellent

Check out the new tabbed browsing add-on collection, Tabbed Browsing Boost! One of its many add-ons is Tabloc!

https://addons.mozilla.org/en-US/firefox/collection/tabbed_browsing_boost

This addon works great against accidental clicks on the tab-close button, but I would appreciate if it would be able to disable the Forward/Backward buttons (also their shortcuts), close-Firefox-button, and any other possible one-click way that may navigate away from the current page, or cause the page to reload. I have a slippery mouse, and it sometimes jumps to the corners, where the top left and right corners mean a serious problem.

Great addon. My favorite one.

この拡張がないとTMPから抜けれませんでした。

This add-on works just as intended and I haven't had any problems.

Exactly what I was looking for, Thank you!

Great addon and does exactly what it's meant to do.

Seems to work well on 3.5.
I would suggest changing the icon to a "key" symbol for lock instead of the pin. The yellow exclamation mark-symbol is fine. Also, the icon on the main extensions-menu needs to be cleaned up, as it looks rather blurry (as though it hasn't be scaled up properly).
Otherwise, nice extension.

Great addon but i don't understand what lock does and how can i activate it to do what it's supposed to do? Is lock supposed to prevent you from switching onto that tab or something cos when i clicked on a locked tab it switched to that, unless "locking" it does something else. Please help

Exactly what I needed.
Stops me from accidentally closing the tab when I'm downloading films.

No issues like some of stated.
Works flawlessly!
With Session Mgr. all tabs locked or protected are remembered!

COMPLETELY USELESS
it makes me lost 30 opened sites

I used this add on on my fast dial page. It did the job of protecting the fast dial page but any links clicked on the fast dial page would open 2 tabs of the same page, like its duplicating every link once.

Had to uninstall until a fix comes up.

This function is the biggest reason why I still use TMP ：)

Two days after reporting Gmail bugs, an update (currently still "experimental") has been released (0.3.1) fixing them.
