Firefox supportforum

When dowloading an AAX type file from Audible, Firefox changes it to MP4 (downloads as AAX with other browsers).

Note, changing the file type after the download fixes the problem. But, is there a way to prevent it from happening in the first place? Also, why changing file type in the first place?

Today using Firefox 93.0 on my Windows 10 home computer I opened the browser to my Audible library on Audible.com and selected a book to download. The browser download window opened with the book file name but the extension wasn't .AAX but had been changed to .MP4. This did not happen when I used Microsoft Edge nor did this happen on my Windows 10 laptop which was still running Firefox 92.0. Once Firefox upgraded to 93.0 on my laptop I now get the same problem as I get on my home computer.

Audible technical support looked into the problem and found that this change wasn't caused by their servers.

I have discovered that if I change the file extension from MP4 to AAX I can load the audible book into iTunes and sync it over to my iPhone which is able to play the file as an audible book. This indicates to me that the actual AAX file was not converted to MP4. For some reason only the file extension was changed.

I wasn't able to find any setting in the Firefox browser that corrected this problem.

Hello everyone I re-install my win7 recently. I can get the firefox browser installed whitout any errors but it doesn't open. However I can see it's open in task manager in processes tab. what would be the problem? please advise

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

Windows 10 did an update this morning and now I cannot access firefox. firefox entry not found. the procedure entry point ?profiler_init_main_thread_id@baseprofiler@mozilla@@YAXXZ coulld not be located in dynamic library. c\programfiles (x86)\mozilla firefox\xul/dll

Please tell me how I can regain control over my own computer, and block companies hijacking or derailing it. I'm very tired of incessant reminders of unwanted updates, as well as their arbitrary limitations, and apparently will somehow have to remove layers of them to regain flash player stolen away by Adobe. If only they had left well enough alone...

The Firefox 78 ESR is the last version of Firefox that supports Flash - how can I reinstate it? Do I have to roll back browser versions to regain control of my own computer? If I had a problem with Flash, I would have dealt with it myself!

Does Open Office respect customers' rights better? I hope so!

Today's update- Facebook shortcuts missing. Followed instructions to update profile. Need 2 separate tabs open- One for Fb, another for the shortcuts. Cannot merge to show on one page as always before.

I was getting a browser error on another site, so tried updating firefox. Now nothing works on firefox. Edge is working, google, windows explorer, etc but not firefox. I have an older PC running I think running Windows 7. can I revert back to previous version of firefox or reinstall to an older version if incompatibility is an issue?
