Firefox Support Forum

Hi, I have checked many questions here in this forum. And have checked and tried all solution suggestions described in question "Firefox does not start at all" asked by user "hampet47". I click on the Firefox icon, the firefox.exe process appears in Task Manager, but that's it. I've tried opening in safe mode, but the same thing happens, just the process appears, but nothing else. I've tried creating a new profile, but that also does not work. After creating the new profile and clicking on the option to start firefox with that profile I get the "not responding" message and have to end the process. I've scanned my PC and nothing wrong here. I've tried both uninstalling-reinstalling procedure and the clean reinstall process and it also did not help. I don't have a Logitech camera installed and never had. Anything else that I can try to fix this? I am running on Windows 7 Pro OS. Thanks

I have a link to Firefox in my task bar. When I click on it to open Firefox, Firefox opens and so does webcvlipper. I don't want Evernote or web clipper to open automatically.

Last week, Firefox performed an automatic update and restarted itself. Now it never starts. I can see firefox.exe processes running, but no window is ever visible.

Things I have tried:

• uninstalling and reinstalling Firefox using latest installer.
• while Firefox is uninstalled,
  • delete C:\Program Files\Mozilla\* and C:\Program Files (x86)\Mozilla\*
  • delete anything under C:\Users\<me>\AppData\ that had "Mozilla" in the name
• tried using Profile thingy (mozilla.exe -P) -- a firefox.exe process was running, but no window ever opened.

This is on a company-owned laptop running Windows 7 x64 and kept up-to-date. Mozilla ran without complaint until last week's automatic self-update.

PLEASE DO NOT SUGGEST ANY STEPS THAT REQUIRE AN OPEN FIREFOX WINDOW. THAT JUST TELLS ME THAT YOU HAVEN'T ACTUALLY READ THIS.

I re-installed Firefox. Every time I start Firefox, I get a long message in a window called “Browser console”: alert() is not supported in background windows; please use console.log instead. There was an error configuring Browsing protection. This may be due to your proxy configuration. Please run the command "/usr/local/f-secure/bin/proxy-localhost-bypass" in Terminal or ensure that your system is configured to bypass proxy for host 'localhost'.

Can somebody explain what this "bypass proxy for host 'localhost" means for my iMac?. (any security risks?).

After deleting my user profile, firefox won't start anymore. Every time I start firefox the Crash Report window opens. This happens also in safe mode. I tried creating a profile with the ProfileManager option, but the result is the same. I have been waiting for a couple of weeks to see if a system update would eventually fix this (I installed firefox from Arch's repos). I run Arch Linux 64-bit. I have also tried installling firefox-nightly and even downloading firefox from mozilla with no success

\Whether or not I use Roboform in my system Tray, or instead try to launch Firefox its Taskbar icon, Firefox launches only about a third of the time. When it hangs without loading its process is still visible in the Task Manager. What to do so that it launches every time?

Dear all, I am on OS X El Capitan, and quite new to MAC OS. I need to use a web browser in 32 bit mode for a website that requires it, so I followed a thread that showed me how to allow your firefox to run in 32 bit mode ("go to Finder/Locate Firefox/Ctrl click Get information/tick "run in 32 bit mode"). Unfortunately when I quit and restart the browser it seems that I am still running in 64-bit mode. The 32 bits links won't work AND I can see in the troubleshooting panel some indications that I am still running 64 bit... I tried to block automatic updates, or to lock the version after ticking the "32 bit mode" in the finder but so far nothing worked. I even tried to restart the computer to see if it did anything.

Has anyone encountered the same issue ?

thanks,

After update to Firefox 57 (Quantum) - I can no longer access the main firefox menu without firefox crashing. Some other menu's work, but a lot crash.

I have tried (after reviewing other postings on this forum):

0) Started Firefox in safe mode

1) Disabling accessibility

2) Disabling Hardware acceleration

3) Created a brand new Profile

4) Output of about:support available here: https://pastebin.mozilla.org/9073540

All with the error persisting.

I've tried system preferences and ctrl click on the FF icon and check/uncheck Open at log-in but FF keeps opening at startup. If I cant fix it I'll have to take it off my laptop so I'd appreciate any help.

Good day,

Everytime, since a few weeks, when I start a new session I have to accept cookies again with many websites. e.g. Google or De Telegraaf. Normally with the Telegraaf I have to log in just once, but since a few weeks I have to log in every time. In firefox settings I have "remember history" on.

Error de lectura XML: entidad no definida Ubicación: chrome://browser/content/browser.xul Número de línea 381, columna 7: <menuitem id="context_duplicateTab" label="&duplicateTab.label;" <pre>this happened since i got the last version of firefox

Hi!

It worked before but suddenly stopped working. When I click the icon, it looks for a second that firefox will start since the icon shows in the dock for half a second, but it then disappears and the program doesn't start. It doesnt even tell me that something is wrong. I have tried open the terminal and entered "/Applications/Firefox.app/Contents/MacOS/firefox-bin -P" but all I get in the terminal is this message "The patch directory path is not valid for this application (/Users/jonatanf./Library/Caches/Mozilla/updates/Applications/Firefox/updates/0)".

I hope you can help me so i wont have to browse on chrome anymore.
