How do I disable secure connections for local domains? like http://nas.local or http://nas.home.arpa ?

I search for the subject but nothing came up. Apologies if this has been asked before.

Hi.

I have several internal sites, each signed with their own internal CA/subCA. These CAs are all named the same, but have different crypto materials.

If I import just 1 CA into FF (directly or in Windows store with security.enterprise_roots.enabled ), the site with that CA works fine (browser warning is not presented), but ALL those other internal sites give this error:

An error occurred during a connection to 10.1.1.1. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE

with no option to add a security exception.

If I add the CA for another site, that one works as well, the others won't. If I remove all the internal CAs, all the sites start working again (with browser warning, ofc.).

I tried in Chrome and Edge and I get the option to create a security exception for the sites for which I did not install their CA, which looks like the ideal/preferrable option to me.

Is this as intended (and why?) or can it be fixed?

This looks somewhat similar to this: https://support.mozilla.org/questions/1170738

Thank you. Davide.

I cannot do anything involving a search, tab crashes. I have used Firefox for many years, and yes, I have updated to the current version. If I cannot get this resolved, I will have to uninstall Firefox and use another browser. Please advise. Thank you.

A while back, I had some very bad cataracts. In order to view text more easily, I somehow managed to change black text against a white background to white text against a black background in the pdf reader's settings. A side effect of this change was that color became grayscale. I would now like to return the settings to default. I've lost the article on how I made the changes. How can I get the pdf reader back to it's default settings?

I've tried uninstalling and reinstalling Firefox. The settings did not change.

Help!

Copying text with the latest version of Firefox 127.0.1 (64-bit) does not catch all lines of a page and its text the marking of these lines are ignored the same page text works if using Chrome

Those marked grey (in attached file) are the only that are captured as all the rests are left out even if they was intended to be marked .

Any help would be appreciated!!!

I found that my session activity on a secure (logged-in) website was being interfered with. I could not log-out of that website. After I closed Firefox, a notice appeared that an update was in progress. Why should a Firefox update interfere with an active session? Is this an updating issue that needs fixing?

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

OS: win 11 x64 Firefox 127.0 x64

I think the v127.0.2 fix to the Youtube buffering issue also fixed the frames being navigated in the wrong order when using < and > to navigate frame by frame. For several months it would occasionally skip a frame with one tap of the button then show the frame it should've shown when you tapped it again.

I was sitting playing on the computer, I go to firefox browser and go to zelenka.guru, I look, and I'm not in an account on this site for some reason. I decided to go to another site, but there is the same problem, as I realized - for some reason I got out of all accounts on all sites.

Hello all. Having updated Firefox a few days ago, we can no longer sign into Instagram. This happens only on Firefox, only since the last update, and Firefox is the same browser we have been using for years with Instagram. The problem is the cookie permission window for Instagram a) will not make a selection and b) will not disappear/close. We have attached a screenshot. There are no close tabs/buttons anywhere on this window, and we have looked the full length of the expanded window. As we have not changed any other setting, have not added any software, and this only happens on Firefox, we can only conclude that we have missed something which may have changed or been upgraded with your last update. This is quite urgent, as this is to manage the Instagram account of a wildlife conservation charity. So far we have tried reinstalling Firefox, clearing cookies, and deactivating/uninstalling all add-ons, however this has solved nothing. Could anyone suggest a solution please? Thank you for your time and assistance.

Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

For the past couple of days when I watch videos on YouTube on my iMac it's VERY slow to start. Sometimes it takes minutes, at which point I have to refresh, and best case it takes about 1 minute to start.

I have cleared the startup cache, cleared cookies and restarted Firefox.

Also, YouTube works normally on both Safari and Chrome.

Not a super 'tech' guy so any basic steps I can take are appreciated.

Thank you!

I'm getting this error when trying to access Instagram posts on here in the past few days:

Something Went Wrong

It opens regularly in every other browser I have.

Hi! I have more than one device for Audio connected to my laptop. Obviously the default device provide by laptop but also I have a Jabra Headset EVOLVE 20 SE MS and Jabra Speaker SPEAK 510 USB/ Bluetooth. Also my webcam Logitech C930e provide a microphone.

When I use Google Meet, in Chrome I can select on Meet Audio Device Select the different microphone or Speakers but in Firefox I can only select the Default System Speaker.

I would like to know how to change between my Audio Devices for the output or can switch between my different speakers.

I've been experiencing a problem in Firefox where, when I scroll, the incoming part of the page momentarily goes blank and then loads to normal. This issue becomes more pronounced on pages with a lot of elements. Also, this issue becomes more vivid in smaller screens compared to larger ones. It feels like the browser is taking time to paint the part of the page.

This issue only occurs in Firefox. I have tried this in Chrome and Safari.

Here's what I have already tried:

• Disabled hardware acceleration and WebGL.
• Disabled smooth scroll and auto-scroll.
• Opened Firefox in safe mode (troubleshoot mode).
• Confirmed that I have no extensions or add-ons installed.
• Reset Firefox.

Despite these attempts, the issue persists. This problem is affecting the usability of the website. How can I resolve this scrolling issue? Any help would be greatly appreciated.

Firefox "Tabs" when operated automatically will not work on links within emails that I trust. When I manually select the link to open within a "Private Tab"(Personal, Banking, Shopping, etc)the link will work, and connect. I have checked the Windows 10(64) Firewall and my VPN, and nothing is set to block Firefox from connecting the auto-opening Tab. What is the trouble?

I've been unable to complete the installation of the latest version of the Firefox browser for Windows 10 for several weeks because my Bitdefender online protection repeatedly blocks the connection to incoming.telemetry.mozilla.org saying: "firefox.exe attempted to establish a connection relying on an unmatching security certificate to incoming.telemetry.mozilla.org. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."
