Sometimes one ends up with a lot of tabs, each of which has some unfinished task associated with it -- which is why the tab hasn't been closed.
This extension lets one annotate tabs with extra information. This information can be associated with the particular tab (by unticking the "persist" option), or just the page URL. This is useful both for remembering why you had a tab open, and for recovering from crashes.
The extension will have a yellow icon on tabs with annotations.
One can also view a list of all the annotations, and go to the relevant tab directly from there.

Special thanks to @TildalWave for the icon!
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
