Looks like SNI settings via about:config in Nightly don't apply. Nightly version: 90.0a1 (2021-05-24) (64-bit) OS platform: Win 10 pro, 21H1 19043.985

1. network.security.esni.enabled ->true 2. network.dns.echconfig.enabled ->true 3. network.dns.use_https_rr_as_altsvc ->true 4. network.trr.mode -> 2 5. in Network settings DoH is enabled and Cloudflare (default) is selected 6. 1.1.1.1 with WARP is used

I have a Windows XP machine kept solely to run those applications that wont run under Windows 10, and there are several.

It has a hardware switch that removes access to my network and is only connected briefly to print to my network printer then disconnected as the default. It does allow access to the Internet but that is only ever to one particular site, nominally once per year.

One program requires a yearly update to an internal text file from its parent organization. Previously all I had to do was briefly connect to my network access that file from that organization using the Firefox version on the XP machine to download that file directly to the program that needs it.

I tried that this week May 2021 only to receive an error message from somewhere to "Try Internet Explorer".

I have a workaround solution involving my W10 machine and a thumb drive to transfer that 1K text file manually, but the process of direct transfer to the XP machine used to work, and is much more convenient.

What has changed, such that the Firefox version on the XP machine no longer works?

Ideas please.

Hi, I need to use alt+scroll to zoom in and out on a website I use regularly. However, often, I will use alt+scroll to zoom out and end up leaving the session as firefox backs out to the previous page. This means that I have to spend a long time logging back in and loading my page.

I have tried shortkeys, but it doesn't seem to support modifying shortcuts using the scroll wheel.

How can I disable this shortcut?

Thank you.

firefox 88.0.1-1 on linux Since recently firefox started to open random udp ports that's what i see in netstat udp 0 0 0.0.0.0:36531 0.0.0.0:* 16227/firefox udp 0 0 0.0.0.0:43783 0.0.0.0:* 16227/firefox It only happens on some sites likes youtube and discord is that related to http3 in some way? there is nothing in about:networking

I am just not sure if this is anything to be concerned with, i did a bunch of searches for firefox open ports, but couldn't find an answer

I recently updated FireFox to it's new version and added add-ons. Usually, when an add-on gets added, it shows immediately on the top left on the toolbar. (in videos and articles). However it doesn't display on mine. I did some research and found another method: customize toolbar -> drag the add-on to the toolbar. That didn't work either because no add-ons displays when i enter customize toolbar. Instead, there's an add-ons icon to drag. Dragging it on the toolbar and clicking on it doesn't do anything. I also read that if the toolbar is full there would be a + icon and when i click on it add-ons shows up. (my toolbar is actually empty and i don't have a + icon). So yeah, i'm left with no solutions. Appreciate some help and suggestions.

When I try to print something from google drive it launches the firefox (?) printer dialogue. The I click next, and get this screen requiring me to download it before going to the HP printer dialogue. Can I skip this part, the downloads get so full!

I do like the ability to customize web pages using usercontent.css. I wonder whether this capability still exists in FF 89. I may become a crotchety old guy and stay on 88 if that feature has gone away.

Every time I try to open Firefox it asks me for permission to install Firefox Software Updater. I then say no and Firefox opens with a notification to update to the latest version. I opted out from updates but the only option available is for the Firefox to ask before updating, there is no option to opt out definitively. Is there any solution to stop notifications and installing attempts?

Thanks in advance

The firefox on my phone allows me to speak what i want to SEARCH for from the URL box. EX: "show me lawn mowers for sale near me". I want to be able to do the same thing on my laptop. How do i do that? Yes i do have an internal microphone.

After an automatic update Firefox had a terrible surprise for me. A beyond ugly user interface. And NO WAY to fix this with a simple toggle switch back to classic mode. There are theme's available, but still it looks unusable to me. This kind of updates should be beyond Mozilla, maybe don't hire former Apple employees, the esthetics don't have to be " slick and modern"

So after a long fight with almost losing my plugins, saved tabs (100+) etc.. I downgraded successfully to 88.

Step 1 (Secure your profile) Open menu, Click Help, Click "More Troubleshooting Information" Go to the line which says, "Profile Folder" Hit open folder

Pay extra attention during these steps: Now you are browsing in your active profile. If you did this after upgrading to 89 version. Make a back-up copy of this whole folder!! Rename it back up.

Open the file "Compatibility.ini" with a text editor, and empty it. Save and close.

Download and install the previous version of Firefox, After installing don't forget to disable automatic updates.

If the profile isn't loaded, browse to "about:profiles" and find and select your profile to get al your plugins, tabs, favs, etc. back.

Its a terrible shame i need to write this down for people to avoid the frustration of a terrible update

Bonjour, depuis plusieurs semaines j'ai des bugs graphiques sur l'interface de Firefox et sur les pages web. J'ai attendu en pensant que ça passerait avec une nouvelle mise à jour mais rien ne passe. J'ai testé le mode dépannage et le mode réparer Firefox, le problème persiste.

Pre v89 Windows 10- for some reason, one of my bookmark folders, containing many subfolders and individual bookmarks, has disappeared from my bookmarks toolbar. interestingly, the lost Bookmark folder it does appear on my android phone. Is there some way of finding it on my desktop and restoring it from there, or possibly restoring it from my phone? I would think I would like to try to do this before installing version 89. Thanks in advance.

I don't know if it's a need to mark your territory, or some marketing major blathering about "holistic new user experience paradigms"--and I put up with the stupid move to tabs on top (because apparently some dev felt that what Firefox users really wanted was Chrome!)--but this is a hideous, steaming turd.

'Oh no, showing the 'close tab' icon and clearly delineating between tabs interrupts the synergistic flow of the UI! Let's make the tabs one disgusting, unreadable blur from left to right! Also, let's make them take up more real estate on the screen, because people have higher resolution screens now--we can totally dominate the upper quarter! Oh, and force the change to the new layout, don't give people an option to revert--and don't warn them, either! EVERYONE MUST SEE OUR MAJESTIC, PERFECT, UNASSAILABLE VISION! Surely that won't confuse TF out of a bunch of grandparents whose hapless children/grandchildren will have to completely re-explain, multiple times, how to get to Facebook!'

Rolled back to 88.01, went through the "new profile" crap you put in to discourage rollback/cover for poor programming, and disabled automatic updates. Barring a major, earth-shattering security vuln, I'm done updating. And when that time comes, I'll find another browser.

Posting here because they've stopped soliciting feedback--probably because they know they've unleashed a sloppy splattered dook onto the world and they're tired of being screamed at.

In the current version (89.0) the shortcuts for the context menu are not working anymore (i.e. right click + L for "Copy Link"). I had to downgrade to 88.0.1 to make it work again. Is there any possibility to get those shortcuts back in the actual version?

When I restart my computer firefox keep logging me out at then I need to add email and password, then my bookmarks and plugins very annoying any solutions here ?

Good day , I tried to downgrate to 88 cause the layout of newest update was crappy (is) So it made a new profile but al bookmarks etc are not there I did do the about:profiles and see 3 diff 1's i know 1 is the 91! since if i click on open folder on the root directory it gives a whole long list on all 3 the profiles but it does not show in browser When i try to start a other profile i keep getting the pop up to make a new profile for older FF

How ever i do not want to keep making new profiles.. I just want all mmy bookmarks and paswords and add'on being in the browser

I am not a computer saffy so if any 1 can explain how to fix in easy to understand way i would be happy Ty on forehand

I'm currently running Firefox 88.0.1 on Windows. When Firefox first released 91.0 I updated but quickly reinstalled an older version, I hate the new look with the floating tabs and oversimplified colors. One of the reasons I use Firefox is cause it doesn't look like a Chrome wannabe. But now I can't open my browser without it prompting me to update. I would like to stay up to date for security reasons and the such. Is there anyway I can keep the old Firefox look and still update?
