Firefox Support Forum

I purchase audiobooks on Audible.com using my Mac (OS Catalina). When I download a purchase Firefox sends it as an MP4 file which is incompatible with the apps to play the audiobook. Safari and other browsers do no do this - the files come as an .aax file. Even after I have an .aax file I cannot play it using Firefox because Audible.com does not recognize my registered computer. I get an error message: Document "LicenseForCustomerToken" couldn't be opened. Incompatable with QuickTime Player. FYI: QuickTime Player is a video (MP4) player app on my computer. So, once again, Firefox makes the .aax file appear like an MP4 file to Audible. It's doing some kind of unrequested and unwanted conversion of .aax files to MP4.

I hope you can fix this in your next update. i've worked with Audible to solve this issue, but they cannot help and are telling me it is a "known issue" with Firefox and recommend I use a different browser.

Have update from 89.0.2 to 93.0 today, and like many others it seems been caught out by the assurance that passwords & logons would automatically be transferred. I've found the advice about copying key4.db & logins.json from the Old Firefox data folder that has appeared on my desktop. The problem is I can see key4.db but there is no trace of logins.json. I have show hidden files enabled. Have tried searching the folder and still got no trace. NB there was also no logins.json in new profile folder until I created an account for this support posting, although I realise it may not create until a log on is saved.

The issue is the missing passwords are computer generated and only saved in my firefox browser, and there were definitely some saved with usernames etc.

I noticed a comment that logons.json is a text document. I only have 4 of those - AlternateServices, pkcs11, SecurityPreloadState & SiteSecurityService State. I assume none of these could be logins under a different name?
