Diễn đàn hỗ trợ Firefox

Firefox disappeared from my computer late Sunday night.

I have not been able to reinstall it.

After downloading the installer the process seem to proceed okay at first. But the progress bar stalls at about 95%. Then the installer sends a message that says something like installation failed.

Please help me.

I have been using Firefox for a decade: I have never had this problem.

I am running Windows 10 on a HP Desktop.

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."

I want to start fresh with a new install of Firefox , like it is the first time I have ever installed it. I do not want to refresh, because I will be getting my previous data.

Tried 5 times to download Firefox Each time get the message in a box " 7zip can not create temp folder archive" when I attempt to execute the .exe file This is not helpful. What is this "temp folder archive" and where is it???

Help please! I'm not tech savvy and I accidentally deleted my Firefox profile.

I was trying to fix my Firefox high CPU issue and followed the advice below. I didn't realize deleting my profile would mean losing everything. Is there a way to restore my old profile? I didn't delete the files from my old profile.

I would greatly appreciate any advice to help fix this. I'm on Windows 10 Pro. Thank you!

"Run" command: firefox.exe -P I deleted my only profile “default” I choose “Don’t delete files” Then I created a new profile

My 11-year-old PC (custom build, now running Windows 10) crashed badly (hard drives and Windows 10 were irretrievably broken), so I bought a new motherboard, etc. and installed a new OEM copy of Windows 10. I must reinstall almost all software, including Firefox. The old C: drive SSD is intact. After I install Firefox on the new machine, how can I restore the tabs from the last Firefox session?

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?

I downloaded the updated version of Firefox and replaced the old version, but my system won't accept the newer version. How do I reinstall the older version for my Mac.

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).

Hi I am trying to install FireFox onto my Macbook Air 10.14.6, and despite following the downloading steps on the website I can't seem to access it. I keep getting this image pop up, but when I tried to drag FireFox into my Applications folder, nothing changed. How do I install this?

I mistakenly loaded a browser called Freshy Search. I was trying to access a CarMax type program, and Freshy downloaded. I now get the Freshy search window every time I open a new tab on Firefox. I want to delete Freshy from my computer. Thanks

I have just bought a new laptop and followed the directions to copy my profile across. It did not copy or transfer my local folders though. I have seen some old threads about this but need it broken down very simply please as I am zero technology geek

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.
