This extension does exactly what it says: it stops links from opening in new tabs. Whether it's an old-school link with a target="_blank" attribute or a modern site using JavaScript to spawn tabs, No New Tabs forces the content to open right where you are. THE UNBREAKABLE UPDATE (v3.0.0). Earlier versions only worked by stripping basic HTML attributes like . Version 3.0.0 now handles every technique websites use to open new tabs—it also intercepts JavaScript to keep new pages in the current tab. Temu can't get away with it anymore. Cleans Links: Strips out _blank, _new, and a bunch of non-standard targets. Blocks JS Spawning: New in 3.0.0—prevents scripts from hijacking your browser flow. White/Blacklist: If you actually want Gmail or other specific sites to open new tabs, just add them to the whitelist in the options. Or if you want to ONLY prevent new tabs from certain pages, you can configure a blacklist. AJAX Friendly: Works on sites that load content as you scroll, like Facebook or Twitter. Easily configurable: The extension popup allows you to easily enable/disable the extension, or add the current page to the whitelist. If you find a link or a script that manages to escape, let me know and I'll see if I can hunt it down. Email (available in the options page) is the most reliable way to contact me. I am very responsive Version 3.0.1 (2025/01/11) - Bugfix: Command clicking (or control clicking for you non Mac folk) should open links in a new tab, even with this extension. The previous update broke that, so this one fixes it. Version 3.0.0 (2025/12/24) - The "Unbreakable" Update: Renamed to No New Tabs. - JavaScript Handling: Finally added the ability to prevent scripts from opening new tabs/windows via JS. - Overhauled logic to handle modern web-app navigation better. Version 2.1.2 (2025/11/25) - Performance improvements - You can now use a popup from the extension to easily enable/disable the extension for the current page Version 2.1.1 (2025/9/25) - Small bugfix in fenced frames (really just an annoying log message). - Made config page dynamic, no "Save" required. So fancy. Version 2.1.0 (2025/9/19) - Significant optimizations and performance improvements. - Removed jQuery dependency, other optimizations. - Reduces memory usage and should improve page load performance as well. Version 2.0.4 (2025/9/17) - Version 2.0.3 was a rollback to version 2.0.1. - Fixed a bug in 2.0.2 which reversed the behavior of white and blacklisting, effectively breaking the extension. Sorry! Version 2.0.2 (2025/9/9) - Fixed a bug in rewriting links with rels. - Made the extension overall more robust, fixed some possible race conditions. - Made the options page prettier. Version 2.0 (2024/10/15) - Updates to manifest V3 - Big rewrite under the hood. Settings are not persisted from previous version, sorry. I do this in my spare time and I didn't have the gumption to spend more time on this than it already took to just get the basic functionality working again... Version 1.9 (2020/10/15) - Bugfix: previous version of the script did not work when the "Filter HTML forms" option was deselected. Version 1.8 (2017/12/16) Big change - Should be noticeably faster (only monitors updated/added elements on page, rather than rescanning the whole page on modification). - Added ability to enable/disable by clicking on extension button (also added a toggle in the options page). - Added the __blank (two underscores) target. - Requires fewer permissions, should be fewer corner cases that it misses. Version 1.7 (2015/11/25) - Allows the user to specify what the "_blank" target should be rewritten to (don't do this if you don't know what it means!). Version 1.6 (2015/10/25) - Now disables _blank (etc.) on the tag as well. Version 1.5 (2014/03/07) - Now works on HTML forms as well. Can be disabled in the options menu if you prefer (although please tell me why, if you do!). Version 1.4 (2013/11/6) - Exceptions can now be specified as a blacklist instead of the default whitelist. Version 1.2 (2013/7/7) - Now works with pre-rendered pages (frequently generated from Google searches). As a side-effect, now requires the webNavigation permission to know when new pages are loaded or swapped in. Version 1.0 (2013/3/9): - Now works on dynamically-loaded AJAX content. Useful for sites like Twitter and Facebook. - Added a whitelist option. - Now requires permission to view your tabs, so that I can know which page you're browsing (needed for the whitelist). Version 0.9 (2013/3/3): - Now catch rel=ext and rel=e, which are sometimes used to open new windows in javascript-based techniques. Version 0.8 (2012/7/3): - A change in the previous version meant that my script didn't operate while the page was still loading. Fixed now. Version 0.6 (2011/6/24): - Added the _newtab target Version 0.5 (2011/04/29): - Now works for file:// URLs as well. Version 0.4 (2010/10/28): - No longer needs permission to view your tabs or history (mind you, it wasn't making use of this permission before). It still needs permission to access "Your data on all websites", but there's no getting around that -- it rewrites the links on every page you browse! Version 0.2 (2010/07/21): - Now blocks the _new target as well.

TabBlock
This extension is for anyone, who uses websites with pop-up ads (ads that open in a new tab). 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.

Selection Search
Search for the selected text in search engines With this extension you can easily search for text you have selected. When some text is selected you can left click the selected text to get a popup where you can choose a search engine to search with. In the options page you can customize the look of the menu, which mouse button that should activate the menu, which search engines to show, and a lot of other things. When you install this extension you will get a warning that this extension can: "Access your data on all websites." This is needed because the code for the popup-menu needs to be added to every website for it to work. If you want to report a bug/issue, please use the following site: https://github.com/Pitmairen/selection-search/issues Alternatively you can use the support section on this site (chrome web store), but I get no notifications about new posts, so I may not notice the message. Some people have asked for ways to make donations to the project. If you want to make a donation you can do so by buying me a coffee: https://www.buymeacoffee.com/pitmairen 0.9.7 - Improve support for IME input in toolbar popup (See issue #173) - Change to use a html class to shown/hidden the popup menu to make it easier to override the display property of the popup with custom CSS. 0.9.6 - Fix issue where icons in some cases could fail to load because the fallback icon loading did not work. This may improve the icon loading for some users. 0.9.5 - Add option to trigger "open all" feature on submenus with middle click only. - Make back button in toolbar button go back only one level at the time - Fix issue where "open all" on sub menus could crash if the submenu contained separators - Change default search engines on new installs to use https 0.9.4 - Add ability to customize the toolbar popup with css - Include separators in the toolbar popup. Hidden by default, but can be made visible with custom css. 0.9.3 - Fix issue where some icons failing to load could trigger a loop in the image loading, which could cause high CPU usage and pages failing to load. 0.9.2 - Improvements to icon loading. The icons are now loaded in the background worker, similar to how it was done in the 0.8.* versions of the extensions. This should make the icons load faster and with less chance of icons failing to load. Note: The icons are cached in the sessions store provided by the browser. This storage has limited capacity. If you have a lot of search engines or have many large custom icons, you can hit the limit. This will cause some icons to fail to load. If this happens try to use smaller icons if you have custom icons. If that does not help report the issue as it may be possible to make the usage of the storage more efficient if necessary. You can also hit the limit if you make a lot of changes to your search engines in one go, but this should be fixable by just restarting the browser as this will cleanup old entries in the storage. 0.9.1 - Fix issue with context menu items requiring two clicks to work - Fix issue where the context menu items was not added properly - Fix issue where hitting enter in the toolbar search box would not open the first search engine - Changed icon loading to use the icon urls directly, instead of loading the icons in the background, as the background loading does not work properly with manifest v3. This will probably also fix some issues where custom svg images would not load. 0.9.0 - Major rewrite of internals to migrate the extension to manifest V3, as required by Chrome for the extension to continue to work. - No new features or bug fixes in this release. 0.8.63 - Added new buttons to allow adding new search engines/separators/submenus at specific positions in the search engine list 0.8.61 - Added option to enable the search engine popup blacklist/whitelist to also affect the search engine hotkeys. The options is located under Popup menu -> Advanced -> Blacklist/whitelist. 0.5.58 - Fix issue where the popup could be partially positioned outside the top of the browser window and become unreachable. Mostly an issue for very large popup menus with many search engines. 0.8.57 - Fix mycroft integration. - Add an additional source for search engine icons that is used if the default source does not have an icon. 0.8.56 - Added special search engine marker for sites requiring encodings other than UTF-8. Simply append {SPECIALENCODING} to the end of the search engine url. This enables the feature and the browser should be able to auto detect the correct encoding. 0.8.55: - Possible fix for freezing tabs for searches opened in new foreground tab 0.8.53: - Added option to open search in new window - Make it possible to add search url to the submenu root item. If a search url is added it will open when clicking the submenu root item, unless the openall on click option is checked. - Improved replacement of bracket placeholders ({%s}). If "}" must be used inside the placeholder it can now be escaped using "}". - Improved regexp placeholder replace converter. The old "re:" converter still works for backwards compatibility. The new improved converter is called "replace:", and is documented under "More Variables" at the top of the options page. 0.8.51: - Fix issue with saving changed settings on options page For full changelog see:
