Hello, Firefox updated successfully to the latest version(99), but when i sign in to my account to sync bookmarks,passwords...etc. firefox will revert to the olders version(98), and ask to "restart to finish the update".

how can i keep the latest version and be able to sign in and sync details from old version to the new version?

Make sure you install Firefox properly and that you do not launch Firefox from the DMG (Disk Image) file.

Open the Firefox Disk Image file and drag the Firefox application to the Applications folder on your hard drive. You shouldn't double-click the Firefox application to run it from the Disk Image, but instead drag it out of the DMG folder.
