The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Can't load Firefox!!!

In general, Firefox was running very poorly, freezing up at times while loading sites. I once ran RogueKiller and it detected a rootkit affecting Firefox. Following this I decided to reset Firefox. I was also prompted to update Firefox to the latest version, which I also did. After this, Firefox does not open a window upon starting the program. It will show that it is opening on the task bar (I have Windows 7) and then after about 15 seconds the icon appears as if it is not open. Upon checking in Windows Task Manager, it shows that FF is running, albeit in the background. I have tried various anti-virus/malware scanners (Spybot, AVG, Sophos Virus Removal Tool, Malwarebytes, SuperAntiSpyware) and other scanners (TDSS Killer, CCleaner, AdWCleaner) but nothing malicious is detected (even in safe mode). I suspect some kind of deeper infection which is evading all these attempts. FYI Internet Explorer is also affected by the same problem. Thank you so much for any kind of help.

Hi!

After update to 56.0, I was getting multiple following messages when starting and/or using Firefox. Eventually, all my bookmarks loaded without problem, but the error windows appeared consistently:

"Your Firefox profile cannot be loaded. It may be missing or inaccessible."

Attempted solutions (with no success):

 - Delete %appdata%/Mozilla/Firefox/profiles.ini file
 - Delete the whole %appdata%/Mozilla/Firefox folder
 - Re-install firefox
 - Delete the %appdata%/Mozilla folder, delete C:\ProgramFiles\Mozilla Firefox folder and re-install
 - Remove old profile and add new one using "firefox.exe -P"
 - Repeat some of the above 5x

Working solution: Reboot

 - I noticed Kaspersky antivirus was demanding restart after its own update.
 - Firefox error said "inacsessible", and antivirus frequently locks out our files during development.
 - Kaspersky forces its plugins into browsers, so I gave restarting it a try.
 - The Firefox works after reboot with no errors even with the original (restored) contents of the %appdata%/Mozilla folder.

Suspected cause of the problem:

 - The Kaspersky automatically installs its extension into browsers (even after manually removing or disabling them). 
 - I suspect that the updates/installs somehow conflicted.

EDIT: Reformatting for better readability. Added missing info into "attempted" solutions.

Hi, I have a Mac 10.11.6 and for whatever reason I cannot get Firefox to open. I received a message at the bottom of my browser during the last use saying something to the effect of click restore/restart to improve speed. I did this and now Firefox will not open. I get a Mozilla crash reporter screen even when I try launching it in safe mode. I tried the refresh option (by holding shift + option on startup) and still get the crash report screen. I reinstalled it multiple times, tried deleting it and doing a clean install, deleted my profile and created a new one, and even deleted my anti virus program. Nothing seems to be working and I am very eager to get my preferred browser working again.

Thanks very much for your insight!

Using Windows 7 - since installing v41 every time I use Firefox it asks me enable every add-on rather than automatically loading them automatically - how can I prevent this from happening? I want them loading automatically like they were with v40.

I'm getting a blank (white) screen when my Win 7 pc boots up to the desktop (see attached screen shot). It has a small FireFox logo at the upper left corner. After about a minute this window will close revealing the desktop. If you try to close it, it says it isn't responding. As a test, I uninstalled FF and then rebooted. This window didn't open up. I can't tell if it is a FF issue or if some program is trying to use FF on startup but failing. Has anyone else had this issue?

When I install Firefox it works fine. Installation does not include a shortcut on my desktop, so when I attempt to start it again, I go to "all programs." Then I get the "specified path does not exist" message. I suspect that this has something to do with confusion between two hard drives. C: drive, a small SSD, contains the operating system and various other software. D: drive is my data drive, contains other applications, music, photos, etc. The path referred to in the error message is D:\Program Files (x86)\Mozilla Firefox\firefox.exe.

Firefox does not provide the option of choosing a drive for the installation. Is it possible that it installs automatically to the C: drive, and the shortcut keeps sending me to the D: drive?

If you have any other thoughts or suggestions, I'd love to hear them.

I have been using Firefox for years, but yesterday firefox stopped working. That is to say that the task manager showed firefox in the task list with 14%CPU but no browser page was started. ie Firefox running but no screen output. I then uninstalled firefox and reinstalled but I still have the same problem.

Any help on this ?

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:

this morning, I get the above error message when attempting to open ff. I was able to open ff from the start menu(windows 7 enterprise), but all of my bookmarks have disappeared. I had the system administrator attempt to restore my computer, with no results, then reinstalling ff. upon reinstall, I was able to open ff, but bookmarks were still missing. then, a ff update "esr" was run, and now I get the error msg above trying to open ff from anywhere. I cannot open ff at all to restore defaults or run in safe mode to fix.

I use OS 10.9.5 Build 13F1096. In System Preferences, Users & Groups, Login Items I have added Firefox 39.0 to the list of applications that open at startup but it usually closes immediately after it opens. Is there a remedy? Thank you.

Hello,

I can run Firefox Developer 59.0b4 64bit and Firefox Quantum 58.0 64 bit on my desktop, but I cannot run the same browsers on my laptop. Both my laptop and desktop are HP and 64 bit. Any suggestions would be greatly appreciated.

Thanks

I have tried everything I can find to stop bing.vc from opening as the start page in firefox version 39 and so far nothing has worked. I am unable to find any reference to in in about:config; a refresh of firefox did not help; no add-ons refer to it and conduit or search protect do not appear in uninstall programs in control panel. No malware removal tool has any effect on it and I have used all that were recommended on the Mozilla support site. Help please!!

This should be an easy fix because all other browsers and Firefox used to do this. When Firefox is restarted the pages do not reload they just display history. I have to hit the reload current page button to get the new data. This has been driving me crazy for a few weeks. I thought I had if fixed a couple of times but only a couple of pages would reload and now it is all history again.

I downloaded the newest version of Firefox and it simply crashes before it opens.

This is the Crash ID:

Crash ID: bp-19c953f3-7fb3-4ba3-9136-06c9d0181024

I don't know what to do.

Firefox always immediately crashes on startup, giving a message popup box saying: "We're Sorry Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts. To help us diagnose and fix the problem, you can send us a crash report." It then crashes again if I select Restart Firefox, and crashes even if I quit and restart it later.

I have uninstalled Mozilla multiple times with a clean removal and redownloaded and reinstalled and the same thing happens. Also persists even with numerous restarts between removal and reinstallation. Crash ID: bp-fc0e63cc-13b5-4657-995f-8dfa02150919 is one of these crashes.

Firefox used to work all the time every day; this started 4 days ago--no new installs of anything else.

I was using Firefox without problem until the last few weeks on my 3rd Gen Carbon X1 running fully-patched Windows 10 64-bit. At some point, it just stopped launching. I have tried everything suggested here https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions without luck.

In particular, I uninstalled Firefox with Windows 10 "Add and Remove Programs". Then I deleted all Mozilla/Firefox folders under \AppData. Then I went through the registry and deleted every Mozilla or Firefox key. I rebooted, and reinstalled Firefox from scratch using the installer. There are no errors on installation; however, when I then try to launch Firefox, nothing happens (the process is visible in task manager or pslist, but otherwise no windows opens). I have also tried launching firefox.exe from the command shell; likewise, no errors or other response--it just stays spawns the pid but then no window opens or other visible indication that Firefox is there.

I've tried variations on this uninstall/purge/reboot process several times without any progress. I just can't get firefox.exe to launch at all on this system. Otherwise, the box seems to functioning perfectly, and all other common web browsers work fine.

I've also tried launching in safe mode (via command line or keypress) but get no different result.

Any ideas for narrowing the issue?

I tried to delete browsing and web history when closing Firefox and this problem happened with Firefox immediately hanging up not closing except on 'force quit' and then totally not opening at all. It won't open in Safe Mode just zilch happening! Nothing I've tried has worked. I've removed and reinstalled Firefox, it but the same immediately happens. I am an older person and not a tech head! So need some simple instructions. Presently I am using Safari and but would like to get Firefox back and reinstalled again so I can access my book marks. Thanks for your help.
