'''I have been working on this problem for a month. I have read every article ever written about this subject. But given the thousands of people who are having a problem with this I think that this is your problem as well as ours.''' I can install any version of FF and I can fix AND break this very easily. If I only install one version (Nightly, Developer, etc) the bookmark toolbar is easily imported from chrome and displays on Windows 11 perfectly. In the good old days, I could install all versions and they would work without a problem. No longer. The second version will not display the Bookmark toolbar and it breaks the first one that has been working perfectly. I refresh but nothing helps. If I remove the first version (or Second, i.e. Firefox removed or Nightly) then I can fix the first by a refresh followed by an import from chrome. Equally bizzare is that I can break the first correctly running Firefox by merely synching using any mail address I happen to own. The toolbar will not come up even after a refresh. I examined the profile. The loaded profile contains a blank series of paragraphs (current profile) followed by a set of filled out paragraphs(previous profile). I use a second existing profile and it will work AFTER a refresh. Forgive me, I know that many of you are volunteers, but there's is something ilvery wrong with the coding to cause such a complex failure of Firefox. I am a believer and donated a small sum every month for years. I have been writing to Mozilla and complaining but nothing comes of it. Please assume this is a coding problem and not a failure of the user to do things right. I cannot break any browser but Firefox. Please fix. If you want info from me, just ask.
