In my cfg file for firefox i use a custom DNS server (Quad 9 which uses 9.9.9.9). It appears this causes DNS Leaks while using a VPN.

The line is this: lockPref("network.trr.uri", "https://dns.quad9.net/dns-query"); Obviously instead of writing 9.9.9.9 this line uses the above shown adress.

If i want to use cloudflare which is 1.1.1.1 instead of 9.9.9.9 what adress do i have to use? Still haven't figured this out...

Have upgraded to FF100.0 today. For years shopped at Tesco uk no issues. Today unable to complete payment with error: Access Denied You don't have permission to access "http://payment.tesco.com/en-GB/payment?" on this server.

Internet explorer works!

I recently upgraded to 91.7.1esr and the shortcut icons that open when I open a new page have changed. They are now about a quarter the size they used to be and are located inside small white squares. The squares themselves are the size the icons used to be. This is a nightmare! Can I change them back to the way they were?

This is a comment, not a question. I really only want to applaud Firefox and all the volunteers that contribute their thoughts and efforts in writing solutions, explanations and more to the many areas that need to be addressed, especially newcomers to the world of computers and Firefox. I was not raised in a computer environment, in that I am old, born in 1953. Everything and anything I know is from being self taught by jumping online and giving it a go, stumbling around on the web until things made sense to me. Volunteers at Firefox have been invaluable as they have been my teachers almost from the start. In addition to just turning 69 years of age and a bit out of the range of "computer age" I had undiagnosed learning disabilities (ADD, dyslexia, etc) which made classic classroom learning very difficult. With Firefox (and others) volunteers, I am able to take my time, going over what I read several times until it sticks and I can move on to take in a little more knowledge each time I logged (and still log) on. So thank you to all the volunteers who share their expertise and thank you to Firefox for highlighting the names of the authors and teachers and posting them at the end of their articles. Firefox does not just talk the talk, they walk that walk, and stand as a fine example of how well community, helping out and giving of yourself makes for a better world. Without naming names, there are others who now prefer to remain more self-serving in their efforts, pumping up their version of "security" by becoming CENSORS TIMES TEN, limiting and blocking any and all comments that do not conform to that company's beliefs. Like I said, I prefer not to name names....but "YIPEE !" Thank God they are the exception and not the rule. Ain't that right, "YIPEE !" or whatever your real name is ! As they say...'DO YOU !" Firefox. Keep up the great work and again, thanks to all of the many contributors who volunteers their time, energy and expertise in spelling things out, helping to teach Old Knuckleheads like me, how to follow the maps you draw in verbiage, that is the standard for great teaching methods in the many, many areas of computing that I personally got a late start on. Be safe and Be healthy, everyone, in particular all you volunteers. All of your efforts are deeply appreciated. p.s. My apologies for the length of this, I just don't know when to SHUT UP ! LOL

Hello, I have a strange issue. When I am in Gmail using Firefox, my time is off by 5 hours. I can open Gmail in Edge and the time is correct.

I have 2 time zones listed in my Google calendar. I removed the secondary one and the time still stays the same.

One posted mentioned that they changed the computer time zone and this resolved the issue. I tried that and still get the same incorrect time.

I can log into my laptop and I get the same issue with Firefox being 5 hours off but Edge being right on time.

Any input would be greatly appreciated. Thanks Mike

09May2022 AusEST 5:25pm I have a query related to the printing of an online monetary transaction, and it's associated incorrect time of printing using Firefox.The details in full will be accompanied with an image representing what I will be referring to. However, I am finding that the image will not be uploaded here at the Mozilla Firefox browser support page. The image is less than 500 KB. I have tried .png & .jpg. Could someone please assist me? Kind regards, Harauld.

Recently I have noticed that when I want to display HTML source of the page Firefox asks me to log to the site once again. WHY? I am already logged in. The page is already loaded and displayed. So why it needs my password again?????

In some cases the page is actually loaded once again which can result in different content being displayed as "a page" and different as "a source" (if there is a dynamic insertion on the page changed on every get). But sometimes it shows old, cached source while the rendered page is already changed. I know that I can see actual content by using the Inspector but "show the source" function was more convenient. Now I can not believe that the "source" shown is a source of the actual "page" Such misfeatures make the function totally useless.

Firefox version 91.8.0esr for Debian.

When logging into my financial institutions website it reports back that I have version 91... of the Firefox browser installed and that it isn't supported. I actually have version 101.0.1 as reported by the browser itself. I called them and they asked me to check my version of Firefox by using www.whatismybrowser.com and it reports back that I'm running version 91. Can you help?

I am on ESR 78.15 Oesr (64 bit) should I stay on it or move to another version of Firefox if I am a web developer? From what I can gather they are the same? I am on debian linux kde

Just paid $150.00 for a remote session from my computer store. Advice is: My older computer (2004)and it's graphic capabilities aren't compatible with newest FF. So I'll stick with older version (9) until I decide to get new computer. Firefox is my preference, but if I update, it's likely to break again. Please tell me how to stop all update notices. It is maddening. Or, if you can do it, please do. I don't want to use the others. It has crashed twice, just FF, in the last few days. A system restore saved me, but I updated and lost it. Can you help this not wealthy person? I thank you for your fine product, and your help.

Firefox 100.0 (64-bit) Mac desktop: Apple Silicon Mac mini (M1, 2020) - macOS Monterey v12.3.1 (problem occurred prior years using Intel/iMac 2015; and previous macOS) Extensions: DuckDuckGo Privacy Essentials; HTTPS Everywhere; NoScript Plugins: OpenH264 Video Codec provided by Cisco Systems,Inc. Location: Australia EST

I am wondering if the following is a known problem. If so, I haven’t been able to find the solution online.

I keep copies of home rental online payments as proof of payment should there be a discrepancy with the real estate agency.

This problem can also apply in other situations, for example payment of online purchases, or movement of large amounts of money to varying institutions.

Sometimes the bank payment is delayed and I would like to ensure that not only the date of payment is accurate but also that the time of payment is relatively close. I am finding that the file printed when banking via Firefox is not time dated relatively close to the time of payment. I use Firefox solely for banking as a secure method.

Upon payment I am presented with a bank receipt and an option to print it, all within Firefox’s desktop application. After pressing the PRINT button I choose to print as PDF and save to the computer. The resulting file is what I am referring to.

The pdf receipt is shown with default details at the top and bottom of the page, the bottom being where the date and time of pdf printing occurred. The discrepancy is between that time shown and the actual time of payment. The difference can be sometimes up to 12 hours!

Can someone please assist me to rectify the situation?

Kind regards, Harauld

Mozilla clearly lost it with their unique identifier, anyways i got a question on this topic.

If i download Firefox here https://www.mozilla.org/en-US/firefox/all/#product-desktop-release there will be a unique identifier, but if download it here https://ftp.mozilla.org/pub/firefox/releases/ There won't be such an identifier.

So, which is the better option since i know little about mozilla.org not sure if it's secure. Also when i download from the first link, what will the unique identifier track exactly since i open my browser and paste the URL for download, i don't come to the downloadsite from any other site or search result, i directly go there, so what will happen with the identification in that case? I know i had a similar thread before, but question is still open.

I went to the official add-on site and I did not see the Add-on named "multi containers" made by Firefox themselves, yet there were about 6 pages of add-on's similar named 'container' but not the one I wanted which is called 'multi containers' add-on.

Hi all. I am having a strange issue with Discord. I can get notification sounds and all other media plays fine there. But whenever I try to "speak comment" or set the settings to always speak comments, nothing happens. The tab shows "playing", but no audio comes out, and nothing shows coming through on the mixer.

Chrome does speak as expected. A different computer, same version of Firefox also does speak as expected (in a different voice though). So that narrows it down to something in this particular copy of Firefox that is causing the problem. Plugins, settings and extensions on the two computers look the same. Also tried a different audio interface. If anyone has any ideas, please let me know!

Hello, for some reason firefox and all firefox related browsers have developed a problem on my system. All videos and streams stop playing if the window/tab loses focus. This is not the first time this has happened but earlier this year using the about:config flag I will mention below the problem seemed to be fixed but now it is back and worse than ever. I have a symmetrical gigabit connection and the problem only occurs in firefox and it's related browsers, no other aspect of my internet is affected, just video/streams and only in these kinds of browsers.

I do have a bunch of extensions but all are ones I have had for a long time, years in most cases, they were not the cause of the problem before and starting in troubleshoot mode plus a fresh profile in a fresh instal confirmed they are not to blame now either.

To be precise about the issue, when I say the videos stop that is exactly what I mean, there are no lags, no buffering, no partially loaded video bar( where applicable), no tab crashes, no connection problems, no warnings about certain tabs or extensions slowing things down, nothing at all, the video simply stops.

I have tried

- safe/troubleshooting mode to rule out any extensions
- with and without my vpn running
- doing fresh installs of the browsers/ complete fresh slate, revo uninstaller pro ran and using fresh profiles 
- found some suggestions for the about:config page, namely window_occlusion_tracking
- found some contradicting information about hardware acceleration but I tried both with and without and it makes no difference
- experimenting with different versions of firefox, so if you can see which version I am using as I post this, the reason it is not the latest version is because I have tried rolling back through older releases to find one that works, but have yet to suceed,

But no matter what I have tried I cannot get the problem sorted. Either I have that specific window and tab as the sole active window on my device or I need to click into it and either reload the tab or push the play button multiple times before playback resumes.

Open to ideas because i'd rather not have to resort to chrome, thanks
