I have to use Windows 10 (Home v:1703).

I'd like Firefox to be my default browser, but it's not listed in 'Choose an App'.

There's just Microsoft Edge listed, along with Internet Explorer, and an option to choose an app from the shop.

Microsoft Edge is also presumptuously shown as the default app to start with.


If Firefox isn't listed, how can I set it to be my default browser - or, isn't this 'allowed' in Windows 10 ?

Hi all,

I rely heavily on FireFox (primarily for the multiple profiles and extensions it provides), so deperately trying to solve a problem I'm having. When I launch Firefox on my Mac (10.12.6 - Sierra), I immediately receive an error: "Firefox quit unexpectedly."

I've tried a number of different approaches to resolve including:

1) Starting Firefox in safe mode (by holding down the opt key on launch) - same error occurs 2) Removing Firefox from the Applications folder, and removing Firefox folder from the Application Support folder under the Library (which also removes all my profiles). Then reinstalled Firefox 57. - same error occurs 3) Tried installing older version of Firefox - version 56.0.2 (after removing previous installation as per step 2 above) - same error occurs 4) Tried a machine restart (very early on) - same error occurs.

I've run out of ideas, and hoping someone may be able to shed some light or suggest further troubleshooting options? Desperate to get it working again!

Cheers, Mark

The detailed error report (or at least the start of it) is here:

a tech cleaned up my computer and reloaded windows 10 and firefox but gone are my bookmarks accumulated over the years. I have the old memory drive and maybe I could take it back to him but I need instructions cause he does not seem to know how to do this. Or maybe I can try on my own. I have some bookmark data backed up but it's not up to date and not in a format that seems to open up...I also did not see any way to import back on that external drive file. I'd prefer instructions to recover from old disk drive.

Thanks

I finally uninstalled Chrome and put in Firefox. Haven't used it in years.

On my screen most pages are "wide" -- so a horizontal scroll bar appears at the bottom of the page, and to see the very right hand side of the page, I have to scroll over.

I have tried the CTRL and - but all that does is shrink the text on the page. It doesn't make everything actually fit on the page horizontally. See the uploaded images of a question I found on this topic on this forum. Even though I've shrunk the font size down in the second one, I still see the horizontal scroll bar at the bottom. Even if I shrink it all the way to the minimum (which results in a tiny font I can't see), some of the page appears off-screen and has to be scrolled over to be seen.

I have tried for an hour to fix this and there doesn't seem to be any way. HELP!

We are currently having to role back to FireFox ESR 52.9 from the latest Quantum build of FireFox 60.3.0. Due to the fact that this version utilizes WebGl 2. Our older systems will not render one of the educational games we utilize in the our School District any longer due to the fact that Quantum uses WebGl 2 instead WebGl 1. We have tested and verified that ESR 52.9 renders the game properly.

I have been trying to disable the automatic update in utilizing the user.js file and the cfg file. The computers are apart of the domain. From what I have read only new user profiles will get the new user.js settings while all existing profiles will retain the old settings so we plan on reimaging these computers so all existing profiles will be wiped.

I have also seen users block the updates by changing the Host File which we will not do. Some sites state create a profile folder in the defaults folder other show place the user.js file in the pref folder. So I am lost at this point. I have followed this guide as well:

https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Enterprise_deployment_before_60#Changes_Over_Time

I have placed the 00_admin-prefs.js with the exact settings shown and have the mozilla.cfg file in the same folder as the js. both are in the defaults\pref

When trying to run FireFox I am am not getting:

Failed to read the configuration file. Please contact your Administrator. (I am the Admin). My domain creds give me admin privileges on all computers.

I know this folder also holds the channel-pref.js so I am not sure if I can add what I need to that file.

If someone would please help me determine what is going on. Why wont firefox copy the either a user.js file or utilize the cfg file I created to each new profile that gets created when logging into the computer.

We have a client that used to run on local computers running the latest ESR version, they recently changed to a terminal server environment and during the setup 59.0.1 made it onto their new setup. Multiple issues have arisen that were not present on the old system and we need to move them back to the ESR version on the terminal server environment. I read online that you cannot just directly import any profile versions 55.0 and up to earlier versions so I am asking if I can instead use a mozilla account to sync over their data instead without causing a catastrophe, and if anyone happens to know what I might expect afterwards if this could potentially work.

I completely removed Firefox and deleted all folders. After installing Firefox fresh, Firefox sees that it was previously installed?? "Looks like you've reinstalled Firefox. Want us to clean it up for a fresh, like-new experience?"

I uninstalled Firefox (supposedly) "completely" using the guide here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

Why does the new install Firefox recognize that it was previously installed? Uninstall tool needs to uninstall Firefox COMPLETELY. Since it lies, can someone help tell me what is the appropriate steps for COMPLETE removal?

Firefox magically stopped working tonight. Based on reading help files and past forum posts, here are things I've tried with no luck:

Note: Running Windows 7

- Rebooted (of course) - Uninstalled through the task manager and reinstalled. - Uninstalled and deleted the C:/Program Files/Mozilla Firefox directory and reinstalled - Once reinstalled, attempted to start in safe mode via holding down Shift while loading - Attempted to start in safe mode by attempting to type many things in the run window:

        Firefox -safe-mode
        Firefox /safe
        "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

- Attempted to add a new profile by typing in the Run window (after reinstalling):

        "C:\Program Files\Mozilla Firefox\firefox.exe" -P 

None of these solutions have had any results. No matter what I do, no Firefox related windows will come up and I get no error messages of any kind. Most of the time I at least get a busy cursor for a second and a firefox.exe process will start. I've kept the Task Manager open through most of the attempts and killed firefox.exe between all different attempts. Most everything I do will still open a process (I have two of them still running right now) and I kill all of them in between attempts, not to mention shutting down. I even did a hard battery pull on my laptop just to be sure. I'm not making any headway. If I could at least get an error message that would be nice, but I get nothing at all. Any other suggestions?

Hello, My Firefox was always crashing so when I tried to uninstall I would get an error message (don't have it now). My 15-year old went into CCLeaner and deleated all the registry files, programs and folders to do a new install. Now when I try to re-install using the latest download I get the following two errors:

Firefox Installer.exe - Application Error: The exception unknown software exception (0x06d007e) occurred in the application at location 0x000000076F4B832.
