Hi,

I'm having an issue with Firefox (on CachyOS, but i'm pretty sure that is not relevant) when I try to hit domain with PORT number.

To be clear, I have a "service" I am locally hosting on a more widely available "domain.com" (those are examples of course...) I am using this typology to still be able to generate Let's Encrypt certs for domains (that I own) not accessible outside my network for those sub-domains, and am using therefore Pi-hole to serve the few IPs of my few "service123.domain.com"

When I use a Chromium based browser (or FF ESR v128) the only DNS query is for "https://service.domain.com:8000" is "service.domain.com" (as seen on pihole queries and in FF-ESR/Chromium DNS cache), whereas FF 135 there is first a "service.domain.com" (righfully answered by my local DNS), and then a second query "_8000._https.service.domain.com" is sent, but my pihole doesn't seem to recognize (and shouldn't have to interpret anything concerning ports), so it sends it to upstream DNS (which are unable to answer)

I have disabled DoH, and every extensions. So I am really lost on what as changed in FF that would explain this, or if it's a pihole config problem (weirdly only affecting FF 135+ ...)

Feel free to ask anything, I may have omitted important info. Thanks in advance

I'm afraid I cannot continue using Firefox, after the last change, since I can no longer keep my tabs open after closing a session, as I specified in the settings: "Open previous windows and tabs." Can someone help?

I reinstalled FF on 30 Apr 25 and it performed normally for a few days.

It is now 3 May 25 and we're back to where we started.

I started FF and I'm getting the tour screen on one tab, the privacy notice on another

All the tabs I pinned are just spinning their wheels

And all my extensions are gone.

I did a clean install of Windows 10 on a larger SSD for my laptop. After installing my Bitdefender AV and firewall software I installed Firefox latest version. I cannot login to sync my account. My email address keeps getting rejected with the message: “Mistyped email? *name@domain*.com does not offer email”. It is the same email that I have used to sync Firefox across all my devices and Win 10 PC’s. It is a domain we bought or registered for a private email service. It is the same email I used to create this account using Firefox on my iPad to make this bug report. Firefox is allowed thru the firewall, but many Windows sub programs are not. I did reboot several times after install with the same result. Currently not running any extensions as I haven’t tried to install them without sync. Is there some windows service or sub program I need to unblock? Never had this issue on any other device or PC when trying to sync. Any suggestions appreciated thanks!

Please 🙏 I am tired of the same thing nothing changes I will get control over my podcast and Cash app pay pal and they take it right back I truly know who's doing this where do I start

The latest firefox browser for windows desktop pc broke the ability to log in to at&t (also called yahoo) email. The email works fine on microsoft edge and chrome. It worked fine on firefox until the last update.

Late last week I updated Firefox to the latest version. Ever since, I keep getting the same error message that I typed in the subject line. I've seen previous recommendations on how to correct it, but none of them work, probably because there's been more updates since what I've come across. I'm getting this error message on multiple sites, including my bank account and my business email account. I'm presently typing this on a different browser (Brave), because I was getting the same error trying to find answers using Firefox.

Any assistance would be appreciated; thanks.

I'm trying to use a script which requires a question mark after the "dot com." I.e., if the url should be http://www.URL.com?custom_URL, it changes it to http://www.URL.com/?custom_URL. How to I keep it from changing the URL - and what is the point of jamming that slash in there in the first place?

This is my second attempt at getting an answer. Can't anyone help me with this?

I've noticed that whenever I press ⌥⇧Space (option-shift-spacebar) in Firefox Developer Edition, it causes the page to refresh.

This behaviour seems to be consistent across devices.

Is there a way to change/disable this behaviour? It is very inconvenient, as it often causes me to accidentally trigger a page refresh when I type an em dash (`—`) in a text input (opt-shift-dash, and then type a space character after it, I'm very likely to hit opt-shift-space by mistake 🙈).

A video of what is happening . This only happens when I search something up, for example, if I search more than one thing up on Pinterest, Google and sometimes Youtube . . . I'm sure it's not related to any extensions, the only one I installed recently was Privacy Possum, but after noticing this issue I deleted it and it didn't resolve the issue.

Online purchases only work on about 50% of the websites I buy on. The most recent one was buying a gift card from Whole Foods. This is becoming so ANNOYING; before I finally switch to another browser, does anyone know how to fix this?

Hi, I have been experiencing issues lately with Firefox. Attempting to install it often comes up with errors suggesting file corruption but I eventually got it to install. However, now it crashes as soon as I open it and in the past before a system reboot on my PC, Firefox tabs crashed very often. I'm trying to diagnose the issue. I have completely uninstalled and reinstalled Firefox multiple times.

As my laptop is currently experiencing other issues, if there's a specific driver that is causing trouble, it'd be great to figure out what's wrong and what is causing Firefox to not function.

My specs are: Asus Rog Strix G614JIR - (GPU: 4070RTX, CPU: IntelCore i9, SSD 1TB, 32GB RAM).

I have attached the most recent crash. Any help is much appreciated. Thanks.

I have been having an issue with Firefox opening certain websites and unfortunately my self and other friends are forced to use Chrome. It is even difficult to contact anyone at Mozilla on this issue. If we Mozilla doesn't show concern we will easily make the complete transition over to Chrome. This is the fourth time I asked for help and have tried trouble shooting the issue from posts listed. We are sick and tired of trying to get this issue resolved and have been with Firefox for over ten years. Does anyone at Mozilla care? No phone numbers, no direct contact? Why the hiding? Obviously we are all pissed off about this issue.

I keep getting nuisance popup prompts to sign into an old gmail account I had linked to my firefox program. I have since deleted this email from firefox and closed the gmail account but keep getting these popups asking me to log into this old gmail. How do I fix this??

Hi – When I type a URL into the address bar, I get a list of suggestions for autocomplete. I can select the site I want, hit enter, and go to that site, or what I usually do is hit command+enter, which opens the site in a new tab. But for the last couple days, when I hit command+enter, the autocomplete deselects and I don't open a new tab. For example, if I type "go," the autocomplete suggests "google.com," I hit command+enter, and the current tab I'm on goes to "go.com."

This is really a pain because it's a very natural part of my workflow to go to websites in new tabs. Of course I can just open a new tab and type in the URL there, but I'd love to be able to keep using my browser the way I'm used to. Is it possible that I made a change to my settings accidentally? I can't find anything in the Firefox settings but I imagine i must have done something. I did check and none of my keys are stuck or anything.

I'm on MacOS Monterey, Version 12.7.2, and my Firefox is version 136.0 (64-bit)

Thank you very much!

I am using the version 115.20.0esr (64-bit) and have noticed I have links in my bookmarks, that are either from other bookmark folders but I never copied them over, or I have new links that I never clicked to be saved? I have deleted those I found but some more keep popping up?

Click on bookmarks, the drop-down menu appears, click or move cursor on an entry in the list, the new drop-down-menu of 2nd level appears. If the list contains many entries the 2nd level drop-down menu overrides 1st level. This does not happen with firefox preceding version. Note: attaching a picture because a webm video is not accepted.
