when i go to my website on firefox it says "Secure Connection Failed" but it loads fine on safari. i've never seen it do this before. Is this a firefox issue?

full error message: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Error Code: PR_CONNECT_RESET_ERROR

how do i fix this?

This note from ChatGPT explains the issue I am having on my LG Windows 11 notebook running Firefox.

Looking... Given everything you've tested, I don't think this is your LG or audio drivers. Especially since YouTube works in Firefox and ChatGPT voice works in Chrome on the same machine. That combination screams Firefox-ChaGPT compatibility quirk. My hunch is, for now use Chrome for voice, Firefox for everything else. And if you want, report it to Firefox support. Include that ChatGPT voice plays no audio but transcribes fine. Mention Windows 11, Firefox version, and that Chrome works. That's useful for them. And yeah, no shame in sticking with Chrome for voice until they fix it.

I am running into a strange issue with the Firefox app installed on my new mobile phone, and it occurs consistently while browsing almost all websites. The problem is that after a webpage loads completely, the right side gets slightly cut off. It doesn't seem to be caused by display scaling, font size, or screen zoom. Because if that were the case, pinching to zoom with two fingers should have brought the hidden right side into view. For example, on Reddit, when I try to check my profile or notifications, the right side gets cropped out. On the other hand, this Firefox support page is displaying properly, with no part cut off. I have attached screenshots of both. I am encountering this issue on several other websites as well. My device is a popular Samsung model. Other browsers, such as the pre-installed Google Chrome or MS Edge downloaded from the Google Play Store, do not have any such issue. So far, I tried removing all extensions from Firefox, but to no avail. I couldn't find anything relevant in the settings that could cause this either. I tried toggling the protection settings between Standard and Strict, but it made no difference. Is there any known fix for this issue?

this issue has arisen suddenly over the last month. so i try to load bandcamp and for a few moments i'm able to go from page to page. after a certain short amount of time has passed between me opening the site and using it, just seconds, upon me clicking a link, pages initially appear to load [the refresh button switches to the X icon] before they quickly halt and keep me stuck on the same page. attempting to open a link in a new tab in this state gives a blank page - not showing as about:blank in the url but the intended destination. sometimes when i try to confirm a change on something i have uploaded to the site or try to log in, bandcamp gives an error reading "There was network error. Please try again."

so i originally thought it had something to do with using a VPN; initially i thought it was alleviated when i turned it off but i was wrong, problem soon reappeared. i've actually been using zen browser for a while, so maybe it was localised to that? i switch back to regular firefox and it was there too. troubleshooting mode didn't yield any difference either, so there's no conflict with extensions... clearing all bandcamp site data hasn't worked either, now because of this issue i just can't log back in lol. i ended up testing on a non-firefox browser, microsoft edge, and found that this issue isn't present there. so i'm kind of stumped on how to figure this out by myself now. keep in mind this is the only website that is affected by this issue

I use a paid for subscription to Gemini AI. It often creates "visuals" for me apparently using JSON code. These do not show up at all. Moreover, the buttoms and other UI controls do not display well in Firefox. Is there a way to fix this?

For whatever reason when on the front page of YouTube, this magenta border will flash on and off around the top header as well as the button elements, I have no idea if this is Firefox or yt, but I've tried everything, on YouTube, I've tried fixing it in troubleshooting, code, accessibility, restarting browser and computer, randomly removing extensions. Nothing is stopping it. It briefly tried doing it on a different site but stopped on it's own, it's only effecting YouTube and Firefox

NEW NOTE; THIS is actually occuring on other websites now, specifically the Mozilla mdn page I looked at to glance and see if I could figure this out myself. So far still can't fix it

jag har använt firefox sedan det ersatte mozilla, med min nya dator med snapdragon processor vägrar den att koppla upp till en del hemsidor jag har version 154.0b10 (aarch64) och har använt denna dator i 9 månader, men väntar fortfarande på en uppgradering

First off I have always used Firefox as my default browser... better than all the rest. For the last week I've been working on a project on ChatGPT and have multiple times dragged and dropped a screenshot directly into the chat until today... now it gives me a red warning label at the top that says that this browser does not support import of jpeg, png, heic... but I've been doing it all week. Has there a change? How do I keep doing this? And now it won't even allow me to add an image here.

okay this just is bad as of today and last Firefox update and with all extensions off . this is what i got when i tried to post and watch a video. it happens on all the videos on Facebook i have tried contacting them as well and that is an almost impossibility it is only in Firefox they work in chrome and edge i even tried reinstalling Firefox ans still get bland black screen I have tried turnoff extension and still this is what i get

Check https://piunikaweb.com/2026/08/14/firefox-x-images-videos-not-loading/ for details, but basically xTwitter/Melon messed again with their latest update.

Any word from those in the know yet? Having to use different browsers to see multi-pic posts is really annoying.

Chase Banking worked for years using FFox on Win10 PC. and using verification with Message on phone. Now is asking for secondary verification using a phone app that I dont have and cannot load. Can login thru Microsoft Edge and Googal Chrome successfully using PC. Not Happy!

Ever since I updated to 153, the FedEx website goes unresponsive after it pulls up a tracking number: I have to force quit Firefox to get out of this problem. No other website that I use has this issue. Everything else works just fine. What could be the issue here?

Hej!

Vissa foton på Twitter/X öppnas inte på olika konton efter er senaste uppdatering. Problemet verkar ligga hos Firefox, eftersom samma foton öppnas utan problem när jag använder DuckDuckGo-webbläsaren på samma konton.

Mvh

Hi!

Some photos on Twitter/X are not opening on different accounts after your last update. The problem seems to be with Firefox, as the same photos open without any problems when I use the DuckDuckGo browser on the same accounts.

Hi Firefox Support / Dev Team,

I am writing regarding an issue with Firefox Nightly on Android.

The Problem:

I use Firefox Nightly v134 as my daily browser (134.0a1 - Build #2016052927). I really depend on the bottom navigation bar shortcuts because it has dedicated Back and Forward buttons next to the + button. This allows me to go forward and backward instantly without opening the three-dot menu, which is extremely convenient.

Recently, Cloudflare verification (challenges.cloudflare.com on sites like wallhaven.cc) stopped working in version 134. Every time I check the "Verify you are human" box, the page refreshes and asks me to check the box again in an endless loop.

Version Comparison:

Firefox Nightly v134: Has the custom bottom navigation shortcuts (Back & Forward buttons directly accessible), but Cloudflare verification is broken (endless verification loop).

Firefox Nightly v155: (155.0a1 - Build #2016178399) Cloudflare verification works, but the bottom bar layout/shortcuts changed and no longer displays the Forward button shortcut.

My Request:

Is there a fix for the Cloudflare verification challenge on version 134?

Or, if v134 is deprecated, could you please add the option to customize/restore the Forward button shortcut on the bottom navigation bar in version 155?

Device Info:

OS: Android 11

Affected versions: Firefox Nightly 134.0a1 and 155.0a1

Thanks for your help!

After clearing my cache, I got logged out of all of my accounts, and I can no longer sign into Google. When I enter my username it gives me a message that says “Couldn’t sign you in: this browser may not be secure. Try using a different browser.” I was able to log in using Chrome so it’s definitely not a device issue. I already tried clearing my cookies and cache again, and disabling all of my browser extensions, but I’m still getting the same message. Any help is appreciated!

Editing to add, I'm using Windows 11 and Firefox version 153.0
