FF90 install doesn't pull customizations from FF89
FF89 told me I needed to download and install FF90, unlike previous updates, which have happened automatically. It said my FF89 data (bookmarks, customizations, etc.) would be pulled in automatically. Alas, FF90 has not pulled any data from FF89 nor given me any prompts to import from FF89. Any ideas why this happened (or didn't happen, as the case may be)?
