very useful but still needs work Rated 4 out of 5 stars
this extension is one of a kind and very useful, which makes me wonder why no one else has done something similar. I keep it out of necessity but really wish efficiency was better, the performance is very poor even on the most up to date hardware. it skips and pauses, lagging the entire ui of firefox every so often (eg. scrolling and textboxes) on all multicore setups of mine, no matter what the cpu preferences are set to.
other than that it works as intended, adding and removing live bookmarks is simple and it works, though sometimes unreliable this is easily fixed by disabling/re-enabling the extension.
besides performance/reliability improvement, only feature I really think would be necessary to add is some sort of filter. many feeds aggregate or combine all their categories and push them in bulk, this works for full featured readers but obviously not compatible with tickers that have no filtering. safe to say most users don't actually want the whole feed most of the time when this is the case, but for this type of feed there is usually headers or prefixes seperating the categories. so even a simple regexp type of filter would be sufficient, for the user to designate some and/or/not strings to include/disclude and minimise the clutter.
