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 forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

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.

Internet explorer works!

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.

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

i opened firefox (v.95) and tried opening up my email and found that all my saved passwords were gone from firefox on my computer. it said i should crate a firefox account to get my logins back so i did and i still could not access any of my web logins. so i searched the help pages. opened up my profile n made a backup of my key3, key4, n loginjson files, downloaded v.91 firefox esr and copied my key3 file into a new profile.

so i still dont have my web logins ... n now i have an outdated version of firefox with none of my bookmarks either. im sick of troubleshooting n my wifi is almost out for the month.

how do i get my web logins and bookmarks back so i dont have to spend hundreds of hours recreating them?

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.

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...

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

I just need a way to rearrange tool bars, and in particular, move the address bar to the bottom.

I am using: Name Firefox Version 91.8.0esr Build ID 20220330151638 Distribution ID User Agent Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0 OS Linux 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) Debian 11 with Xfce 4.16

I can't open anything in the browser. It always says "secure connection failed" and I cannot reach anything get anywhere within the use of the browser. No matter what I do try. I have looked at a number of workarounds posted online but nothing seems to work. I need some help. I use Windows 10

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

There are multiple screenshots attached below, 2 of them showing setting marked in red. Those settings are pre-configured with the firefox.cfg file. I would like to also pre-configure a list of other settings. You can also find those other settings below.

Anyways, i remember someone from this forum told me there is no "official documentation" for the firefox settings which are listed in about:config. Is there an "inofficial documentation"? If you could reply with the exact setting that i have to change according to the screenshot attached below that would be awesome, otherwise an URL for some sort of documentation would be welcome..

Basically all the setting i want to change exists and can be manually edited using the firefox settings, but theoretically could be easily pre-configured with the firefox.cfg.

All i need are setting-names/ids.

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

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.
