Firefox Support Forum

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

Hello,

I've set up Firefox to ask before updating, so I was taken aback by the fact that today, an update was automatically installed without Firefox asking me... (I was updated from 97.x to 98.0)

It is especially frustrating, as the mandatory "Restart" screen is broken when using several profiles, at least under Debian.

Let me know if you need more information.

Best regards,

Adonis

I bought this laptop because it had Windows 10 so I could download firefox, The laptop immediately updated to Windows 11, no way to stop it. I am locked out of my microsoft account, have been for years. How do I get firefox downloaded ?

I've read all the articles here about importing my passwords and history, but the Import Wizard is ONLY giving me the option to import my bookmarks. Even if I can't get the browsing history I need to be able to migrate my (extensive) password list.

I've exported my Safari passwords as a .csv file, but there doesn't seem to be an option to import a .csv file.

The page here regarding it says the feature is 'disabled by default' but does not say it's unavailable and I can't find clear instructions for how to activate the feature so that I can import my passwords. Can anybody help?

Basically, a requested relaunch blanked my profile and I can't get it back.

I have a lengthy workaround that will take over an hour to fix from backups, before this incident, but I'd really like to understand what's going on. How can my add-ons, bookmarks, history, logins, etc. be gone? If I did a refresh on purpose, why would my shortcuts remain intact? And, I started by backing up my profile folder to a neutral spot, so why isn't replacing it reversing the changes?

As background: The "about:profiles/Restart With Add-ons disabled" button brings up a small button dialogue to choose "refresh" or default "open." I selected "open" because I didn't want to fix my profile and assumed I would relaunch with only add-ons disabled, so this was a potential point of screw-up. I assume selecting "refresh" would reset application defaults and make a mess exactly like I find myself in now. Shouldn't "Restart with Add-ons disabled/Open" relaunch a temporary and reversible state? Doesn't "refresh" prompt a new default profile?

Considering evidence only, it appears I did something to roast my profile before I backed it up, but that's strange and really out in the weeds, and I'm assuming I wrecked it with my current activity.

The default profile name and path are correct. My shortcut links and labels that I use for a home page are intact but with icons missing, the same appearance as if I deleted the cache; is this detail part of application settings and not profile?

My job requires me to download and open files in new tabs consistently. However, when I download these files, I don't want the download panel to obscure my vision. Can I disable it?

I am following all the instructions. It has continued to fail for the past year. I've uninstalled ff and reinstalled ff. I've tried creating new profiles. I can import everything into Chrome or from Chrome to MSE, but NOTHING will import into ff from any other browser.

I've always used the "Always ask you where to save files" option when downloading. Recently (beginning of April 2022), files go directly to the Downloads folder. The "Always ask" option is still selected in Settings.

I've tried un-selecting and re-selecting, restarting Firefox, restarting my computer - basically every iteration of 'turn it off and on again' that I can think of.

I downloaded the latest Firefox to my Linux and got this error message: W: Download is performed unsandboxed as root as file ......etc. There's more, but can you tell me what happened and if I need to worry? I haven't had any trouble using Firefox since the update. I've attached a screen shot of the whole message.

I appreciate any help.

Hi,Why is download showing up on nearly all sites I go to & HOW do I get rid of it permantently I can close it by hitting the X beside the Download,but it Should not be there Thanks Darryl

I don't have time and effort to describe the scenario as I am getting sleepy. But I have pics to describe what I have experienced. But having that experience, I felt started to hesitate downloading your installer of mozilla firefox but I nahhed it to continue installing until I successfully installed mozilla firefox.

I just concern.

Some how Yahoo jumped in and displayed a yahoo Home page with no way of deleting it. I tried installing Firfox..But it became stuck half way..what should I do to get back to Firefox ?

firefox updated itself, which normally would be fine, but now there is a PDF icon in place of my normal firefox icon, and I am afraid to use it now. Is it for real?, can I change the icon back to the old firefox one? Please let me know cause I won't use it now until I know for sure that it's ok and get it back as it was. thank you, Linda

bold text' I need to stop firefox from attempting to download update 99 because it will not download it and it is taking up too much of my internet metered download time.'I have taken it off of automatically download updates,but it still pops up a message every day.
