I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

  • DNS over HTTPS turned off
  • Uninstall all add-ons
  • Reinstall Firefox
  • Create new profile and set it as default
  • Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Last Updated November 1, 2023 {: datetime="2023-11-01" } Summary

This top section summarizes the terms below. This summary is provided to help your understanding of the terms, but be sure to read the entire document, because when you agree to it, you are indicating you accept all of the terms, not just this summary.

   The Services are provided "as is" and there are no warranties of any kind. There are significant limits on Mozilla's liability for any damages arising from your use of the Services.

Terms of Service

   Introduction
   These Terms of Service ("Terms") govern your use of Mozilla accounts, a suite of online services provided by Mozilla (the "Services").
   Mozilla Accounts
   In order to use some of the Services, you'll need to create a Mozilla account. During registration, you will be asked to set a password. You are responsible for keeping your password confidential and for the activity that happens through your Mozilla account. Mozilla is not responsible for any losses arising out of unauthorized use of your Mozilla account.
   Services
   (a) Mozilla VPN is a Virtual Private Network in partnership with MullvadOpens in new window. A Mozilla account is required.
   (b) Firefox Relay allows you to keep your primary email address safe and private from online services by making unique, alias email addresses that allow you to send and receive emails without revealing your primary email address. A Mozilla account is required.
   (c) Firefox Monitor is an informational service to promote online security by informing you of public data breaches. You can scan email addresses on our website to see most publicly known breaches. If you subscribe with a Mozilla account, you will receive:
       Full Report: This includes a complete list of publicly known hacks, including breaches of sensitive websites, such as those for children or adult and dating sites (these sites are excluded from website scans in order to protect the privacy of those individuals).
       Breach Alerts: This notifies you if your email address appears in a new data breach.
       Safety Tips: This sends you occasional online safety tips from Mozilla.
   It is your responsibility to protect your online accounts using strong and different passwords, security questions, two-factor authentication, password managers, and other safety measures. Although Firefox Monitor and Have I Been Pwned?Opens in new window strive to have current data, there is no guarantee that either will have complete or timely records of all public data breaches.
   (d) Firefox Notes lets you take notes in Firefox. A Mozilla account is required to view, edit, and delete your Notes across devices.
   (e) Firefox sync lets you access information stored in Firefox across devices, including your tabs, awesome bar, passwords, bookmarks, and browser preferences. You can enable and disable Firefox sync through the Settings section of Firefox. A Mozilla account is required.
   (f) Pocket helps you discover great content that’s personalized to your interests and save this content so you can return to it later – on any device, at any time.

When I'm in full screen mode, The Apple, "Firefox" "File" "Edit" "View" "History" "Bookmarks" "Tools" etc menu bar shows up at the top and won't disappear. On my iMac Pro, it doesn't show up. i.e. Off.

I can't figure out what is the setting to make sure it does not appear. I went digging everywhere and can't figure it out. If you could tell me what config, etc I'm missing I'd appreciate it.

Screen shot attached to show which menu bar I mean.

Hi, I've upgraded to Windows 11 today and couldn't open Firefox since. Things I've already tried:

  • Reinstall Firefox and delete all old files (Appdata & Program files)
  • sfc /scannow and DISM.exe /Online /Cleanup-image /Restorehealth
  • Windows compatibilty mode
  • Firefox Troubleshoot mode won't open either
  • ipconfig /release & /flushdns & /renew
  • netsh int ip reset & netsh winsock reset

When opening Firefox in any way, i get a white window/just the window border which immediatly closes. When trying to start troubleshoot mode, the small window has the same issue.

I also checked the crashlogs and none were generated. The Windows event-logger also has no entries.

BTW: Here is a video of whats happening: https://youtu.be/AJP4rqZFxlY

I have no idea what to do - send help please.

The bookmarks icons and fonts are too small for my older eyes on my new Ubuntu computer. They are bigger on my older Ubuntu computer. I have tried to find out how to enlarge them without sussex.

I am aware of the Zoom feature for a webpage itself, I am not asking about that. I simply want to have my bookmark toolbar FONTS and ICONS larger.

This has been frustrating. Perhaps including an EASY way to do this for future updates, or an app suggestion that would solve the problem. Thanks for your consideration and (hopefully) help.

I've just switched to firefox from brave, and theres no button on twitch to enable picture in picture. Using the keyboard shortcut (cmd+option+shift+]) works, but I'd much rather click something on the screen. On brave there used to be a picture in picture button alongside settings, theatre mode, and fullscreen buttons, but on firefox this has been replaced by a clip button. There's no option for it if I right click (this works on youtube), and no option in the address bar for either twitch or youtube. I've tried disabling all my extensions and lowering protections but nothing seems to work.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I always set Firefox to open the previous sessions tabs when starting. For some reason during the start up over the past several days Firefox opens to the home page only. I then have to search the history to find the closed tabs. Except for this problem, Firefox is working perfectly.

Today a website told me I needed to enable JavaScript in order to continue, despite the fact that it is enabled. At first, when I received this message, I turned off the "NoScript" extension and tried again, but the website still gave me that same message. So then I went to the about:config page. and it showed that JavaScript is enabled because it showed a value of "true". This sort of thing has happened more than once in the past. I'm forced to go to another browser such Microsoft Edge or Chrome, where I do not encounter this problem. Why is this happening in Firefox, and what can I do about it? My operating system is Windows 10 Professional, and if you need any other details, please let me know. I will appreciate your assistance.

When streaming a video and using PiP, after opening another window or program and then pausing said video that is currently being played on the PiP player window, sometimes this causes the actual video itself being played via the PiP player window to freeze. So the video is paused and I want to resume play but when clicking the 'play' button on the PiP player window the video refuses to play.

The only way to clear this bug is to click the 'close' button or the 'back to tab' button on the PiP player window and then refresh the actual web page. After refreshing the web page and repeating the same steps - the PiP player window works just fine with playing and pausing, but it's annoying that I have to do this.
