Read It Later - Firefox Add-On to Save Web Page to Read Later

I use Firefox browser and invariably have loads of tabs open for pages I intend to read later or just that I just want to remember. The important ones I tag with Delicious but for the rest I usually end up closing them down and then inevitably as soon as I do that I need to look at one. Firefox has an Add-On called Read-It-Later also available as an iPhone and Android App as Pocket. With this Add-On you can save web pages to read later with just one click, the icon appears in the URL dialogue as yellow outline chevron.
When you have time, access your reading list from any computer or phone, even without an internet connection!

You can find the Add-On in the Firefox menu >Tools >Add-Ons (Ctrl-Shift-A)

I will report back when I find out if it helps with my problem.
