Add-on summary
Have you ever been overwhelmed by the number of opened tabs in your Firefox browser ? I do. Sometimes I just don't know how I got there, how is it I ended up with hundred of tabs opened ? Then Firefox lags because it can't handle it and I just can't enjoy web browsing anymore. I feel miserable, my life is a failure.
But I made this add-on to solve a problem here. I believe it is a pramatic and simple solution to find potential duplicates between the opened tabs, allowing you to close those and more.
How this add-on looks for duplicates ?
This add-on estimates duplicated tabs based on their urls and their title. If the url matches exactly the one of another tab, then the two tabs are considered as "trusted" duplicates. If there are differencies in the urls, like an extra parameter or an anchor, the tabs are considered as "untrusted" duplicates. They may be duplicates or not, depending on how the corresponding site deals with this extra parameter or anchor.
For example on a tube site you may add a parameter "&t=72" to start a video at a specific frame. Technically the page is the same than another one without this parameter. But what if the extra parameter is something like an id ? Then it's two different pages.
So untrusted duplicates may or may be not real duplicates, this add-on provides a way to find those but you'd have to check it yourself.
How to use it ?
It is quite simple, basically this add-on comes with a toolbar icon. If potential duplicates are found between your opened tabs, it will display a badge with the number of duplicated urls found.
