Used to be great. Past few months, it occasionally (once every 2 weeks) glitches and opens a few dozen times in the same Chrome browser window, lagging the browser to the point of freezing. 5 minutes later it crashes the extension and I have access to my tabs again.
***Use "Closure" instead*** "Chrome Close Lock" was working fine until about a month ago. It was one of my favorite extensions. Now if enabled, the extension opens dozens of duplicate pages and freezes the browser for at least 30 minutes. To get back to a functioning browser, you have to close each opened tab one by one. I've searched all through the chrome store, and I finally found the perfect one named "Closure." It's a wonderful app that works like I want - doesn't let me accidentally close Chrome. Simply right click on a unused and pinned tab (preferably) and a notification window will pop up asking permission to not close the window without consent. Works well and easy to use. The Closure extension can be found here: https://chrome.google.com/webstore/detail/closure/jjagagcgljmlnihcilbpbfcglnopepjb
do to be useful as what it stated as, but seem like something wrong with the programming, it will open multiple or a lot lock tab, when i just open a tab in new window, starting to encounter problem on open a lot of unecessary lock tab after use it long time, this problem need to be solve.
TERRIBLE !! Seemed like a great idea - and appeared to be, at first.... ..but not for long.... When I start up Chrome it usually asks if I want to restore all pages - which I ALWAYS do... This app then hijacks them all, sends CPU usage to 100% for at least half an hour, sends Chrome usage to over 80%, and replaces multiple tabs on different windows (randomly) with red or blue warming triangle icons, ands nothing works - can swap windows, but all tabs unresponsive... Then costs me 30-60 mins waiting, trying to respond to flashing triangle icons, and then loses some of my Chrome windows with anything from 10-50 tabs on them... ..then they dont show up in 'recently closed' list, as the list is full of 'Close Lock' entries closed by itself after randomly opening them. So, then I have to try and find all those tabs again, recreate the lost Chrome Groups, and put them all back in - complete NIGHTMARE. Absolute BLOODY DISASTER... ....sorry mate - you need to fix this random lockup resource waster or delete it....
Works now, thanks. I'll upgrade my rating to 5 stars if we get an option to enable the close lock by default when you open chrome. I've always felt that this extension would be infinitely better with an auto-enable option.
Not worked today... please fix it Thanks it work again
Addon is dead, not working now!
Keeps me from having to start my work over as my mouse tends to jump from the scrollbar to the close button lately.
Good idea. Extension can only be better if only turned on that "tab" automatically. P.S. Also it would be nice to change that crazy bg images)
Each time you have to turn it on manually!
