Good afternoon folks I can't watch Netflix on my Firefox browser. Do you know why is there a plug-in what is missing or something? He says the version is not up to date While my Firefox is always up to date, can you help me further. Thanks in advance from Trimmy.

Some of well known sites such as "drive.google.com" & "mail.yahoo.com" is resulting in "Did Not Connect: Potential Security Issue page" in Firefox. They are opening just fine in other browsers.

This issue has cropped up since past week in Firefox. Not sure what is the root cause behind the problem. I have tried re-installing Firefox, but still no change.

I have checked the certificates of those sites, and they are seems to be in order. I mean other browsers are able to open without issue, then why Firefox is not opening them for me?

Please let me know if this issue can be fixed in Firefox.

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

Hello. I need help with: `DOMException: The quota has been exceeded.` I'm trying to use IndexedDB. However, the code is requesting persistent storage: `await window.navigator.storage.persist();` (and this is returning true) This website is only storing about 8MB of data and I have a different website storing 200MB of data (userscript) The storage medium still has 140GB available. What quota did I exceed? If this is the wrong place, please direct me to the right place

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

I am using Firefox Browser V81.0 (64-bit) on MacOS Catalina and I'm experiencing issues with downloading files specifically from Google Drive. I can download other files using Firefox, but it doesn't work when using GDrive. I know it's an issue with Firefox because I've tried downloading the GDrive files using Safari and it's fine.

What happens is I'll click download and then there is no prompt that asks me if I'd like to download the file.

I also looked at this thread and followed the troubleshooting measures (including clearing the browser cache and starting Firefox in Safe Mode), but it did not solve the problem: [https://support.mozilla.org/en-US/que.../1157677]

I've also tried un-installing/re-installing Firefox. And I have my adblocker disabled for Google Drive.

Any suggestions for how to resolve the problem?

The Firefox desktop browser is the only one that give me this error Error code: SEC_ERROR_REVOKED_CERTIFICATE I am on a MAC OS using latest version of Mozilla Firefox desktop browser: 82.0.1 (64-bit) Incognito mode, cleared everything, reinstalled the browser and still got the same error. Talked with GoDaddy support and they told me everything is ok on their side. What is going on? Why: Safari, Chrome, Opera, Firefox Mobile (iOS) and so on have no problem loading my pages, but Firefox desktop has?

I looked on my GoDaddy hosting cPanel and the SSL are correctly generated and valid, so I don't understand what is going on with this browser.

Thank you! PS - If this is already answered, please point me to the correct reply.

I run FF on both a Windows machine and a MacBook Pro. On the MBP the browser does not save my tabs, despite "restore previous session" being selected. I do not have this problem on the Windows machine.

I have tried uninstalling and reinstalling the browser but it has not made a difference.

I'm running the latest version of the browser and the OS is Big Sur.

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

dear ladies and gentlemen,

Firefox has been delivered with the new print dialog since version 82.

I have to print around a hundred PDF files at work (usually only the first page of the document). The new print dialog means that there is a lot more work for me here.

Is it possible to set the "old" system print dialog by default or to instruct firefox to always print only the first page of the document by default?

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

• This happens for any filetype, from any source.
• It started happening about a month ago.
• Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
• If it's a small file and I try repeatedly, it sometimes will eventually download.
• Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
• I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

• Used Refresh Firefox
• Cleared download history
• Changed download location
• Reset browser.download values
• Disabled firewalls and antivirus/spyware
• Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
• Cleared cookies and cache
• Ran in safe mode
• Verified Temp folder filepath was valid
• Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
• Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

• I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
• Verified places.sqlite was not set to read-only
• Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

(Edited for readability)

If I open two windows of Firefox, pin tabs in the first, close it and then close the second window, my tabs disappear. In order to use this feature one must work with only one instance of Firefox?

On ubuntu 20.04, the snap version of firefox can't play some videos. Some youtube videos will play but streams won't, and then I get the message "to play video, you need to install the required video codecs". On telegram web and tweetdeck I also get this message while trying to play some video.

Since it's a snap, nothing I do on my system will solve the problem, I cannot install any codecs.

It's firefox 89.0

When I try to watch a video on WSHH, I get this error VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media. I have DuckDuckGo Privacy Essencials installed, and I also have uBlock Origin installed. I disable both extensions but I still see the same error. I'm on Ubuntu 20.04 LTS, and my Firefox version is 77.0.1 (64-bit) canonical - 1.0

I attach the console log.
