Thanks for reviving this! It would even more excellent if the functionality of the old Quote Collapse could be incorporated.
Edit: Thanks. If I may suggest a fairly simple way: wrap the quoted block in a <details><summary/>[quoted block]</details> structure. The summary might contain the first line of the block text.
From up version 3.0a7 you can collapse the quotes. This has to be enabled in addons options.
To create your own collections, you must have a Mozilla Add-ons account.
