Firefox Support Forum

I am a website administrator and I have noticed a lot of 404 errors in my site's CDN access logs. The requested paths are all "/", and the user-agents are all "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:41.0) Gecko/20100101 Firefox/55.0". The client source IPs are distributed, and the ASNs are also diverse. The requests are made to a domain specifically used for static resources (css, js), and the referer is my main website. I suspect there might be a specific bug with Firefox/55.0. Can anyone help me confirm this?

Hi, this is going to be a long one, so many things... Using Firefox the latest Ubuntu LTS, with the latest Firefox from Snap. I'm a very long term Firefox user, never had any real troubles unit recently. I have a vast number of cookies, saved passwords and so on. Reinstalling or deleting cookies or such isn't an option unless fixes are guaranteed to work - if I have to start over then I'll do it with Opera, that is where my grumpiness indicator is at.

The set up is two monitors (working as a single 'screen') attached to an Aspire PC (Aspire X seems to be the model?). I tend to have 'stuff' going on in the left hand monitor, YouTube on the right. The PC is on all day. I know there are log files, but I don't know which is for what or where they are. I use AdBlocker Ultimate.

So what's happening is: Firefox crashes quite often at any time - 'Firefox is not responding - force quit or wait' - always have to quit. There doesn't seem to be any repeatable way to cause this, it seems random.

When the mouse enters the YouTube window (the drawing area, not the actual window) it disappears until the pointer moves out of the window. Jiggling the window size sometimes brings it back, but...

When the mouse pointer actually appears the window is completely unresponsive - clicks don't work, nothing highlights and so on. After somewhere between 10 and 30 seconds things will work for 2 or 3 mouse actions (clicks, drags etc) then do it again. Unless I give it plenty of time, clicking on a video will play a pretty random one - Firefox seems to lose track of where the pointer is.

If I comment on a video the I get about 5 to 10 characters in then nothing happens for 10 to 20 seconds, then any queued characters are shown. Rinse and repeat until the comment is complete - it takes ages.

YouTube is the biggest problem, but there are some glitches in other Firefox windows, I'm supposing that the problems are audio/video related.

None of the above happens with Opera. It's getting to the stage where Firefox is unusable.

I've googled and searched this site but the there seems no solution.

Any help appreciated.

I have been unable to receive the OTP I need to log in. My username and password work fine but then I try to get to the OTP, it doesn't show up on my email and the cell phone number is an old one. Please help. I have a lot of shopping to do.

Is there any way to make Firefox iOS browser Dark Mode a little darker by avoiding the moments when it is loading or reloading a page and the screen is fully bright white?

open app on desktop, closes within 40 seconds whether browsing, playing a bookmarked game or just watching opening page. I uninstalled app, reinstalled with saving bookmarks then without saving apps, it stills closes

Hej på ER, Jag kan inte längre komma in på facebook genom FIRE FOX. Kan Ni hjälpa mig så att det fungerar igen ? Tacksam om ett svar på min mailadress:

The Copilot website text field is the only text field I have encouraged where typing text does not get automatically underlined for spelling mistakes. I have the box ticked for 'Check your spelling as you type' in the general settings, and I have tried changing the about:config layout.spellcheckDefault value to 2. Nothing has worked.

The spell checking feature for the Copilot website text field can be enabled, but you have to manually enable it each time by right clicking the text field and making sure "Check Spelling" is ticked. It is quite annoying.

The "Check Spelling" setting on every other text field from every other website like this very text field I'm typing into right here right now for this firefox support forum, has the  "Check Spelling" setting ticked by default.  

Anybody else experiencing this issue?

Hello! I synced my browsing data yesterday by signing in to firefox account and reset my OS(window 10) to improve my laptop's speed. When I am trying to get back my browsing data back after resetting and installing firefox by signing in to my firefox account and pressing the Sync Now button then its not giving me my browsing data back. Why is it so? Need Help. Thank You!!

Hi Firefox. I have been using Firefox since the 90's. I love the feature that you can save a url complete with that website name, icon, and colors. My desktop is very colorful. I just did an update on Firefox in the last two days. Lets just call it the last update. After the last update an hour ago I just received a notification that Malwarebytes blocked what the call Malvertising. As I said, I have been using Firefox since the 90's as my default browser and I have never seen this before on any browser. There were an few short periods in the last few months when Firefox would just lock up my pc, and I switched browsers to Chrome. But as soon as you corrected the issue, I switched back to Firefox. I got to admit that this Malvertising notification has disturbed me a little. I have Edge, Chrome, and Opera browsers installed as well but I like you the best. Please explain to my why I got this notification from Malwarebytes. BTY, Malwarebytes found a keylogger in my PC that Eset, and Windows Defender scans did not find. So, I am a fan of Malwarebytes as well. I downloaded the Malwarebytes notification of the Malvertising Notification into .txt format, but the button below this says images. If I can send it, and you want it, just let me know.

Can you recommend some kind of extension thet will only check current icons for the bookmarks? Just that. I don't need duplicate bookmarks checker, inactice checker and God knows what else checker. Just icons, that's good enough for me.

After I boot my computer, I can access any of the sites I usually use, but only once. If I then close the site and attempt to open it again (or to open any of the other affected sites), I get the following message: " Secure Connection Failed

An error occurred during a connection to phoenixcommons.cohousing.site. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

The site shown in the error message above is the one I most ofen use, but other very common sites (e.g. Google.com) exhibit the same problem:

" Secure Connection Failed

An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

Yeah, right. I'm supposed to contact Alphabet and inform of the problem?

In contrast, some sites (e.g. The New York Times, The Washington Post) are not affected.

I can paste affected URLs into another browser (I used Brave) and access them with no problems.

Hey Gang -- Has anyone else experienced this?

Whenever I'm on NPR's website listening to a radio program, I can't access any other websites on separate tabs or windows. (they simply won't 'load' or even acknowledge any commands)

I find this to be very strange.

If anyone can help with this minor quandary I would be grateful.

Sincerely,

PS - I am using a PC desktop computer, running Windows 10 and using the latest Firefox version 124.0.2

. .

As of Wednesday afternoon my internal/system mic and speakers are no longer working with FireFox. Geek Squad says it's a problem with FireFox. I'm running Win11 on a Dell laptop that's about a year old. Firefox is up to date, and Windows should be as well.

Receiving this error: Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

My desktop app redirects user to a login screen on Firefox, and I want to automate it using Selenium. My current workflow: 1. Launch Selenium-controlled Firefox browser using GeckoDriver 2. Click on "Login" button on my desktop app. The desktop app launches the login screen on user's OS default browser using the default user profile (in which case I set in profiles.ini to the temp profile copy created by Selenium). 3. (ERROR) Popup on the above error is displayed

Code: import configparser import os

web_driver = selenium_webdriver.Firefox(executable_path='C:\\Users\\mnxl\\.wdm\\drivers\\geckodriver\\win64\\v0.34.0\\geckodriver') profile = web_driver.capabilities['moz:profile']

1. Path to the Firefox profiles folder

profiles_path = os.path.expanduser(r'~\AppData\Roaming\Mozilla\Firefox')

1. Path to the profiles.ini file

profiles_ini_path = os.path.join(profiles_path, 'profiles.ini')

1. Read the profiles.ini file

config = configparser.ConfigParser() config.read(profiles_ini_path)

1. Find the section for the profile to set as default

for section in config.sections():

   if config.has_option(section, 'Path') and config.get(section, 'Path') == profile:
       # Set this profile as the default
       config.set(section, 'Default', '1')
   else:
       # Set all other profiles as not default
       config.set(section, 'Default', '0')

1. Write the changes back to the profiles.ini file

with open(profiles_ini_path, 'w') as configfile:

   config.write(configfile)

I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.
