Overview
Product summary
Review the store description, core capabilities, and common use cases.
Adds a padlock icon that allows toggling each tab's lock/unlocked state. When a locked tab is being closed, a confirmation dialog which allows preventing the tab from closing, is displayed.
📣 IMPORTANT: after locking, some interaction with the page is required for it to work. So you need to, for example, click anywhere on the page after locking to actually prevent the tab from being closed. This is how Chrome works.

Doesn't work. Yes I "interacted" with a open tab.
Sadly, I've had to lower my rating due to some unexpected behaviors I only just discovered. On a regular basis I perform online shopping routines on multiple sites. I thought that locking those shopping tabs would solve the problem of another extension I use to keep my tabs from multiplying by automatically closing background tabs that haven't been used in a preset number of minutes. While this did prevent those from being closed by the other extension, it unfortunately caused an issue that makes it impossible to use while shopping. Every time I try to add an item to a cart, the pop up appears asking if I'm sure I want to leave the page or I might lose changes (when there are no changes to be saved). I tried unlocking all my shopping tabs and pinning them while shopping, certain that would solve the problem. It didn't because although I have "auto lock pinned tabs" unchecked in the extension's settings, it is auto locking the tabs anyway, perpetuating the issue. I've posted the issue of pinned tabs locking improperly on the extension's Github page but have not yet heard back. Original review: Does what I need it too. Stops pinned tabs from changing pages when I forget to switch tabs before typing something in the address bar.
So far works fine with me. I'm listening to Naxos music and going through my online RSS feeds---two sites which I often close by mistake. App is keeping both open with a warning screen if I try to close them.
Nice and Simple
Works quite well for how simple it is, and for this reason I am willing to accept some of the minor drawbacks. On some pages it does not seem to work, when I tried to lock the webstore page the extention did not display the locked icon when clicked. Otherwise exactly what I was looking for, and being open source is a good bonus.
Great except when you have to relaunch Chrome for updates and it won't close because of the locks. You have to unlock everything, relaunch and then relock everything. Not feasible. Also a pain when reloading a page that you have to relock it.
does not work
@gabrielmaldi Nice tool and useful for me. I wonder if the dialog box text could be less generic. I sometimes do want to close sites in which I've made changes that I don't want to save, so it confused me at first. I need to do an additional mental step of thinking "oh, is this dialog because of LockTab, or is this a real message?" Maybe it could say something like "This tab is locked by LockTab. Do you really want to close it?"
Actually made me lose a tab I was trying to lock. Will lock some tabs, but not others. Uninstalling before it can mess me up any further.
Can't believe Chrome doesn't offer this, the extension works great just follow the gif posted by the author below.
