Tries to help people with a compulsive tabs opening habit by preventing duplicated tabs
DDT - Don't Dupe Tabs Extension
The Context
I tend to open and reopen the very same tabs again and again, just to refresh their content. I've usually got lots (150+ on several browser windows) of open tabs, and even with the use of some Chrome extensions it takes too much time to find the one I want to refresh. So, since my Bookmarks Bar is full, and I reopen the website I want to read once again. And again. And again.
The Need
I don't want to care anymore about duplicated tabs. Please remove them for me, oh mighty browser, whenever I open another tab with a link already present somewhere else.
The Result
Whenever the user opens a new tab, either via CTRL/CMD+click on a link or Right click -> Open in new tab, the extension looks for any other open tabs with the very same url and close them if found.
You can enable/disable the extension by clicking on the extension action icon.
Is it safe?
DDT requires two kind of permissions from Chrome:
-tabs: to access the tabs list with their urls
-storage: to save the enabled/disabled state
It does not:
access the network (in any way, not even for checking for updates)
read the contents of the opened pages
It could:
close some tabs you don't want to close: this extension is in Beta stage. I've never lost anything I did not expect to lose in all the testing I did, but please don't hold me responsible if anything bad happens
Known limitations
It activates only when the user requests a new tab, not when you are clicking on a link that opens a new tab
If you really want a duplicate tab, you can open a blank tab (only one a time ;) ) and then paste the link
If a link/bookmark does a redirect in more than 250ms, thus changing the tab url or scheme (i.e. http page redirecting to the same page served in https) later, it won't be matched
