Hi all, I had a firefox account years ago that i forgot about. Ive just switched from google to firefox by downloading ff and when i opened the browser it had all my old bookmarks and things across the top. I deleted that old account and signed into ff using a new email yet my old bookmarks remained. I then did and 'import' from chrome hoping it would overwrite the old things but it did not. So i am now with a new email / account stuck with older bookmarks i do not want, id like to have all my current bookmarks/passwords and the other things ...

What can I do about this?

Thanks

Using Thunderbird 115.5.1 (64-bit) on Windows 7. For years Ive never had a problem with Thunderbird through many releases. With this release it is constantly locking up and requires a reset in Start Task Manager. Otherwise the busy indicator on Windows never changes.
