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.

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

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.

I can not send emails after the new update I am getting this error. Sending of the message failed. Peer using unsupported version of security protocol. The configuration related to smtp.vcn.com must be corrected I have checked all settings and had the ISP check also and can not get past this error.Any help would be appreciated

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

Thunderbird asked me to restart for an update and now all I get Is the following:-

XUL Runner Error: Platform version 78.5.0' is not compatible with minversion >=78.4.0 maxversion>=78.4.0

Can someone please help

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

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

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 have been using Firefox for the past 2 years, but only recently have I noticed that Firefox is using 1 GB of RAM! It never increases or decreases and its getting very annoying now since I have barely any RAM to run zoom with (which for some reason takes up the rest of my RAM). I can't even run anything else, and thats annoying me a lot since my fan has to keep running. I can't upgrade my RAM because I use a laptop, and my laptop is under warranty and I can't afford to lose the warranty by upgrading the RAM. Is there any other way to decrease memory usage beside using about:memory and pressing the "minimize memory usage" button? Nothing happens when I press the button.

Three days ago, Thunderbird started to give me a "Sending of password for user xxx.xxx@gmail.com did not succeed. Mail server pop.gmail.com responded: Username and password not accepted.

I checked that it was accurate in the Saved Passwords panel and it is. I've entered it manually and still get the error message.

When I log onto Google from any browser with this account, it accepts the password. I can then access my gmail account with no trouble. My Firefox password manager shows the same password that is rejected by TB. My Gmail Android app on my smartphone and tablet also accept my logons with the same password. Only Thunderbird doesn't. I've tried deleting my pop.gmail.com login entry and re-creating it under the xxx.xxx@gmail.com account.

I had a Google Security warning 3 days ago, so suspect somebody might have hacked the account, changed the password, but didn't save his new password anywhere, so I have no idea what new password he might have changed it to. I am going to try changing my entire Google password and see if this will allow me to reset the TB password, but any other suggestions would be appreciated.

I have several other gmail accounts on Thunderbird and all of my accounts use the same passwords set for their accounts.google.com under the separate gmail addresses. How do I find out what to do to fix it?

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

Heyo,

       I switched to firefox today and I noticed that on youtube there's an animation (fade in and out) when fullscreening. Is there any way to disable this?

Thanks

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

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?

Hello

 Can you tell me if FireFox has HDR support?

In Chrome everything works, in FF for some reason not. The monitor supports HDR, I watch videos on Youtube

Thanks

I don't want to be completely negative about Firefox for Android 79, but it doesn't work for me. Extensions that I relied on are no longer supported, and the new functionality doesn't make up for that.

Is there anywhere I can download the .apk for a previous version and install that?
