My Dashlane password manager extension wasn't working, so I deleted it and planned to reinstall it. When I tried to download this extension again, I got the following error message: "Installation aborted because the add-on appears to be corrupt."

I have the most recent update of Firefox 147.0.2 (64-bit). Please let me know how to fix this issue, as I heavily rely on this extension to sign in to most websites.

All of a sudden, my Yahoo Mail Contacts doesn't load. The following is the error message where my contacts should be listed. How do I fix this? Thank you

I use Firefox (the current version) on a Dell Windows 11 Pro laptop. I have around 8800 bookmarks, and I've lost around half the tags on my bookmarks. (The bookmarks themselves are OK; I'm losing about half of the tabs.,) This has happened to me twice recently, and I'm restoring the bookmarks as I write these words.(after I'm finished, I'll save two copies of the HTML file for backups. Can anybody tell me why this is happpening, aaand How I can prevent it in the future?

Thanks.

I have lost my passwords on my desktop. I still have them on my mobile. I am currently logged on to Mozilla on my Desktop. If I log on to Mozilla on my mobile and select "Synch" how can II ensure that the mobile passwords replenish those on the Desktop and not vice-versa?
