Firefox Support Forum

I had firefox on my computer a long time ago but uninstalled it. I reinstalled it and it will not open. I did a refresh and it would not work. I went through and deleted the following folders to no avail upon fresh install from https://www.mozilla.org/en-US/firefox/new/

Deleted folders: AppData/Local/Mozilla AppData/LocalLow/Mozilla AppData/Roaming/Mozilla Program Files/Mozilla Firefox ProgramData/Mozilla

Upon fresh installs trying to boot into safe mode results in a window briefly flashing in the taskbar and closing immediately. There's no message or anything asking if I want to boot it into safe mode. I don't care about keeping previous data for Firefox like profiles or bookmarks. I do not know what else to do.

Using Firefox browser for iMac. Recently (10/10/2021) attempted to download .aax files from Audible.com. Files were unexpectedly converted to .mp4 files, making files unusable by iBooks. Conferred with Audible Tech support. Audible Tech confirmed that .aax files are the proper format and that they did not/do not make any format conversions on their end. Audible Tech then suggested trying download with Safari. Download (of .aax files with Safari) was successful and maintained proper (.aax) format. Audible Tech said that he had not encountered this issue before and that it seemed to him that the Firefox browser may be responsible for the unexpected conversion. In the past I have used Firefox many times to successfully download .aax files from Audible.com, most recent prior to this problem was on (9/11/2021). I am notifying you simply to advise that you may have a programing glitch within the download programing portion of the latest version of Firefox (ver. 93.0 - 64 bit) for iMac(s).

This pop-up opens when I download any file. I have tried to go to about:config, but couldn't find browser.download.manager.showAlertOnComplete. How do I get rid of it?

How do I reset the settings so I can play MPeg4 videos in the browser without a dialog box asking to download it? I've tried going under Settings but it won't let me select "Open in FireFox."

Hi, my mac broke, All my passwords were saved in firefox account. As everything happen so suddenly, I did not remebered my firefox account password and changed it.

Hi,

It was OK for me to download file from a link before, but since a while ago, when I single click on any link (ex., Firefox Installer) it showed nothing and nothing happened (Normally I think dialog about if open or save/when to save should pop up). I also try other way to open the link then: 1. If I try to open a new tab on link, then a empty tab was opened (as attached image). 2. If I right click the link and click "Save Link As..." then it will pop up the save folder selection dialog.

I hope to have any suggestion to fix this issue. Thanks in advance for any support.
