TabBlock
Prevents from opening new tabs.
This extension is for anyone, who uses websites with pop-up ads (ads that open in a new tab).
red icon -> TabBlock prevents opening any new tab.
green icon -> TabBlock allows opening new tabs freely.
Note! Redirections to ads in the same tab still work! You can try to block them by using other extensions or simply return with "back" button.
TabBlock does not block any normal ads.
Manifest v3 Update: The new approach in Manifest v3 prevents extensions from running in the background all the time, leading to a cold start that can significantly increase the time needed to close a new tab. However, this is purely a cosmetic downgrade - TabBlock now filters out all requests to new tabs instantly, in addition to its ability to close tabs.
This means that even if you see a tab open, it won’t begin to load at all.

doesn't work
So, if a webpage like Yandex, which opens new tabs automatically when clicking to the image section, this plugin will not work until I first click it, and if I do, it will simply prevent Yandex and similar from opening that page at all, even in the same tab? This is worthless!
works when pinned
Exactly what I needed to stay focused. Thank you!
Doesn't do anything.
Great, but with an irritating floor... It stops you from opening up tabs manually. When it's switched on it does its job well, stopping all those annoying separate tab pop-ups, but you have to switch it off every time you want to open up a new tab yourself. If you can make it so that you can still open up tabs yourself whilst blocking the pop up ones, it would be perfect.
It's a great extension, but it prevents me to opening a new tab manually or restoring closed tab with Ctrl+Shift+T, maybe you can make exceptions for this? like opening new tab with "+" button or Ctrl+T, and restoring closed tabs with Ctrl+Shift+T. And manually disable and enable needs extra hand movement, it's either you make exceptions or make a keyboard shortcut to enable/disable the extension functionality. And another thing is there's a critical bug when I closed my browser then opening it again it will closing my blank tab over and over again causing my CPU usage go high. I'll change my review if you fix these problems. Thank you Dev!
Add hold ctrl before click to allow tab to open

I think this is fantastic of an extension, i think the only improvement i can think of is if this can have an option of enabling on specific sites like www.domainname.com/* that way you can still open new empty tabs yourself.
Yep if your on sites that open a add when you even look at your screen, this thing will take care of that easy, Chrome doesn't stop these sites from opening tabs forced. This extension will, it will stop the forced ad sites from loading by closing them so fast they won't have time to lead at all so no hassle, and no issue from b-ad sites. This isnt a Anti-virus, this isnt a Adblocker, but it is a Tab blocker and a sanity saver! It's also super easy to turn on and off. Must have!
Works perfectly as intended
Works like a freaking charm, only complaint I have is that the icon color can be confusing, you think it's enabled by default as it is green, indicating ON except it's not, you have to click the green to actually turn it on (then it becomes red). It's either the opposite color or current color, every developer does it differently. +++++ 5/5
so good i hope its can be active based on active tab/ url ! if u uppdate that features its definitely perfect 5star
Works just fine, better than new-tab blocker. Thanks for not disappointing me like they did. Make sure to turn it on! It'll be red if its off, green if its on. Just click it on your extensions tab.
The dumb me didn't realize that you have to activate and deactivate the extension. It's a good extension, and does what it needs to do.
Does what it says on the tin, but atleast on mobile when reopening kiwi browser with it active it will kill all of your open tabs, needs some work to not just delete your stash of tabs
This app kill any new tabs.. which other tab blocker missed.. everyone should download it
Hate those sites that randomly open tabs with viruses on then for no reason . This extension is a life saver.
Doesn't work
since google now blocks this. any alternative or work around?
Works perfectly! Manga websites open new tabs with ads? Not anymore! Compulsive searching? Social media addiction? Solved!
works as intended, but will stop anything new from opening when turned on, including new windows and apps completely unrelated to chrome. this means that if you close chrome with it turned on, you can't open chrome to turn it off. the only reason I was able to uninstall was because I was still able to open an incognito tab, log into my Google account, open the chrome web store, and uninstall it from there. if that hadn't worked, I would've had to do a factory reset through keyboard shortcuts. it works as intended when you remember to turn it on, but there is no easy way to turn it off if you close chrome completely because you won't be able to open it back up with it on, so I say it's not worth the risk as this is a major flaw in it's design.
Doesn't work. Tabs still open.
It's the best product on the market that exactly works.
WORKS GREAT
Good sad it wont work soon
Works great, sad that it may soon no longer be supported
Works great once you know how to use it. Better enjoy it for the next 4 months. It will be removed from the Store because developer abandoned the extension years ago and MV3 is now the new norm.
If you are using your pc to watch football/sports livestreams, don't bother installing it. It DOESN'T work!!! None of them does anymore.
This is great, just remember to turn it off and on though
With this extension enabled, the standard command for opening new tab (ctrl+T, or '+' sign in the tabs bar) stops working. This is unacceptable.
This extension is nearly perfect, it does what it says it does. There's a major caveat though. it doesn't work on a per-website basis, instead it stops tab creation in every single tab not just the problematic website. Please make this website-dependent... it would be way better.
epic
Does exactly what I need. Perfect extension.
Very nice. I wish it had a way to set certain websites to not open new tabs. Instead of blocking any and all tabs.
its good but remember to turn it off before you close out of your browser, but in case you forget, open task manager then type in chrome and hit end task
was searching for an addon like this for ages! Install and works perfectly fine - nice to block all than annoying stuff on streaming pages.
Works very well. Convenient but you will have to remember to turn it off for new tabs. Thank you!
It works very well. Blocks those annoying tabs from opening. Maybe it works too well. Remember to shut it off before closing chrome or you won't be able to open other tabs for that session. Had to reboot the pc. Maybe add an option to shut it off automatically when closing chrome? Seems pretty easy
Great work.
It no longer stays enabled when you close the browser. You have to enable it every time you open Chrome. I start Chrome in kiosk mode with no keyboard so there is no way to enable it every time. Not sure if TabBlock or Chrome changed.
Great, just what I was looking for.
why is the on off just not apparent its clicking the extension btw yea you go click it then its just on no indication of that tho or anyone saying it why idk. but you go back click again and its off thats really dumb but ok it works thanks for at least that. also there is no red green anything in the opera browser so that bit of info is pretty much useless
Beautiful extension <3 For someone who hates watching... *definitely legal* movies and shows because of all the annoying tab ads, this is amazing. Big thank you!
A BIG THANK YOU!
Brilliant! Finally something that works browsing the dire internet we are on nowa-days
Its amazing! even though it doesn't allow me to open tabs until the extension is disabled, It's doing it's job. Its just that you have to turn the extention off before opening a new tab.
This works really well! There are a couple things to note. For starters when enabled this extension blocks ALL new tabs from being opened even if you the user want to open one. Therefore, it is highly recommended to only enable it when you are on a website that invokes a lot of new tab ads. For me its where I watch sports streams. When it is enabled it does in fact block the new tab ads for all of the websites that I use it on. Would be 5 stars easy if it could learn the difference between a new tab that wants to be opened by the user and a pop-up new tab ad.
Literally doesn't work. Popup tabs galore. Don't even bother with this extension.
