I've had a lot of crashes, some just firefox, some the whole computer. In process of migrating to new machine so wasn't overly concerned. But after a restart today, I found I could not get firefox to open at all. After finding the system searching for firefox.com, I checked program files\mozilla firefox and firefox.exe is not there. A search showed it not to be anywhere. Not ready to stop using this machine just yet. Any way to get firefox.exe reloaded without losing all my related stuff??

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:

WerFault.exe - Application Error: The application was unable to start correctly (0x000279). Click OK to close the application.

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

How do I fix this so I can go back to FF and off IE?

I tried to change the language but the browser itself keeps being German, I can only set my preferred languages to English but that doensn't change anything, neither does re-downloading Firefox nor re-downloading Firefox in English - the browser is always in German and that's annoying because then, pages like airbnb are in german too. Everything else on my mac is in English.

I can be actively browsing or be afk, it doesn't matter it seems, but sometimes tab would just crash. Can be active tab or some other, I'm kinda lost. I suspect it's hardware acceleration related, but I would like to fix the issue rather than turn it off.

Some reports:

bp-dffa0904-8976-421e-bb3a-7a5aa0190327

bp-7cf2d617-22a2-4f6e-ad3b-db92f0190327

bp-682cc861-90c0-4186-a369-f30a80190325

I would love to find a reason and a fix for that. Using latest nvidia drivers and latest firefox.

For an unknown reason, Firefox refuses to start, giving a small box with a message that says " instruction at 0x3fc89352 referenced memory at 0x00000000. The memory cannot be read."

The character string beginning with 0x3 changes almost every time. I have uninstalled Firefox several times and reinstalled it and nothing works. Any idea what happened and how to fix it?

Cannot even open it to run troubleshooting, or safe mode or any of that.

System: Win 7 Pro, Intel i7 chipset with 16GB RAM

Thunderbird runs perfectly well.

I have been having problems with firefox lately. Every time I try to run the program it automatically closes without giving an error message. I am running Windows 10 and this happens in safe mode as well. I have tried doing a clean install of firefox - that did not fix the problem. I tried deleting my profile after uninstalling then doing a fresh install, this did not fix the problem either. I ran a virus scan and did not detect any malware. I don't know what else to try.

I cannot get Firefox to open on my desktop, every time I try I get the mozglue.dll missing message. I have read several other people with similar problems, but none of the solutions seem to work for me.

I have tried uninstalling and reinstalling Firefox several times. I do not have AVG installed on this computer, I have checked several times and uninstalled anything with AVG in the name. I use Trend Micro Internet Security, it is updated to the latest version. I tried disabling my Trend Micro while reinstalling, it did not help. I tried going to Adobe and downloading the Win 7 flash player for Firefox, it did not help.

Should I download and upgrade AVG even though I don't have it to start with? Does Mozilla have a way I can simply download the missing file (I wouldn't want to download it from another source)? Is there some other way to troubleshoot this missing file that I am missing?

My Firefox version is 50.1.0. My computer is running Windows 7 and is a 64 bit OS.

Administrator on 64-bit Windows 7 Professional unable to open existing Firefox (45.0.1) or install 46.0.1 (with save or run) -- ALL ATTEMPTS produce this pop-up: "A required privilege is not held by the client."

Version 45.0.1 was working. As I usually do and have done for many versions of Firefox, I downloaded Firefox Setup Stub 46.0.1 with Save rather than Run. However, I could not run it from the download. Firefox was still working. Then I used the Update from inside Firefox (which I presume was the same download), and Firefox has not worked since. I cannot open it with the icon on my taskbar, by using the Start menu, or by clicking on firefox.exe in C:\Program Files (x86)\Mozilla Firefox.

I have spent HOURS searching and reading and trying possible solutions to other problems (not Firefox) where the users had that, or a similar, message. Nothing has worked.

The Securities tab of the Properties of the firefox.exe file shows three "Group or user names" -- SYSTEM, Administrators (with-my-name-here), and Users (with-my-name-again). SYSTEM and Administrators have all "Permissions for Users" allowed (except for "Special permissions" for which neither Allow nor Deny is ticked). Users has ticks to Allow only for "Read & execute" and "Read".

The Advanced Security Settings show me as Administrator as the Owner. I have "Full control" in Permissions (not inherited), and a second entry with me as Administrator also indicates "Full control" (inherited from C:\Program Files (x86)\ for this entry). The SYSTEM entry also has "Full control" (inherited from C:\Program Files (x86)\ . The Users (with-my-name) has a "Read & execute" Permission (inherited from C:\Program Files (x86)\ .

So, I have "Full control".

What does "A required privilege is not held by the client" mean?

Who is the client?

What is the "required privilege"?

And where does one get it?

For a few days I have been receiving pop-ups about updating to a newer version of Thunderbird. Normally I would do so without hesitation (as I have done in the past with Firefox). However, I am now afraid to attempt this in case the same thing happens with Thunderbird and I can't access my emails. At least I can use another browser (as I am obviously doing to post this).

Years ago I used Netscape Navigator (preferred) and Internet Explorer. The first time I used Firefox was at an Internet café on a holiday. I had to learn to use it because it was the only browser on the machines. When I got home, I downloaded Firefox and have been using it ever since. I loved the multiple tabs (which IE did not have at the time). I have IE and Chromodo on my machine, but I only use them for sites that don't work with Firefox (fewer and fewer as the years have gone by).

Can someone help me so that I can return to Firefox? Please?
