More of a piece of feedback than a question: when opening tabs from a collection (using firefox Beta), it seems that the browser treats this as restoring a previously closed tab rather than opening a new tab and navigating to a site/bookmark. This ... is problematic. And causes some weird behaviour. - Oftentimes (and seemingly at random, can't tell whether this is due to updates or if it just changes at will) tapping a site in a collection causes it to be opened in a background tab, instead going to and refreshing whichever open tab was last displayed before opening the new tab. This makes the new (collection) tab appear at the top of the tab list rather than the bottom, and is overall extremely annoying. - Sites added to a collection seem to remember (some?) previous navigation history, meaning that visiting that site and then navigating "back" to get to the home screen instead navigates to whatever was visited previous to saving the site to the collection. This is entirely consistent for the collection entries where it happens. This is not how an equivalent of a bookmark should work. - Often when opening a site from a collection, it seems that what is opened is a cached version from the previous rather than actually refreshing the site from the web. I previously had this issue for a very long period, before it finally went away, but has recently returned again. Checking a news site or forum and having to remember to refresh it manually after opening is, again, extremely annoying.
