Not everytime. I tired cleaning again today, after making a fresh backup of my bookmarks on a separate drive, and it did not destroy the bookmarks this time. Maybe it only happens if Firefox has already created a certain number of bookmark backups already? (since I had cleaned recently, and Firefox only creates new backups by itself every now and then, there probably weren't any backups to be cleaned this time) Nope. Nope. Yes. Nope. I'm using Firefox Developer Edition as my primary web-browser for years now. Never in all that time did it "lose" its bookmarks by itself.

In fact I'm using the latest official release of Firefox Developer Edition: https://www.mozilla.org/en-US/firefox/developer/ This is a different product from Firefox "Beta" or "Nightly" builds. Nope, it has happened to me several times now. First time it happened was quite some time ago. Can't remember which exact version of Firefox it was back then, but probably pre 100. Sorry, that is beyond my knowledge.

As the title says, CCleaner destroys the bookmarks of my Firefox profile! And I'm explicitly not talking about bookmark backups. I'm talking about the actual bookmarks. If you start Firefox after CCleaner has been run, then all your bookmarks are gone, not just the backups! And, because all bookmark backups have been removed too, you can't even restore your bookmarks! This has happened to me several times now. The first time I had to go back to an old backup I still had on my USB HDD, which means that I lost all my bookmarks from the past months... (Now that I know about the problem, I make a fresh backup on separate drive before running CCleaner, but that can't be the solution). Yours sincerely.
