Original Post
I wasn’t really thinking and deleted Firefox Preview Nightly due to the constant crashing and downloaded Firefox Preview. I never thought about my Collections, which I had several. Will they sync or are they gone forever? Might I get them back if I reinstall Firefox Preview Nightly?
My Comments
They are gone forever. There is a bug filed for this: https://github.com/mozilla-mobile/fenix/issues/4424
Sorry about your experience.
Oh, it’s a bug? So there is a chance I can get them back if that’s fixed?
More of a missing feature. And no, your collections are gone. Sorry.
Context
As of 2024, collections do not sync, and there is no way to export them.
In addition to the bug I referenced in my original comments, the request was refiled to Bugzilla, and there is a Mozilla Connect discussion as well.
Technical folks can use the Firefox debugger (and a desktop Firefox instance) to backup & restore Firefox app data (including collections).
