Hello, Since yesterday, the Firefox web browser crashes systematically. This has happened well over a dozen times. I've tried multiple step-by-step solutions: deactivating extensions, troubleshooting mode, repairing firefox, uninstalling and installing Firefox, trying several versions of Firefox (Quantum, ESR, Nightly), downgrading to an earlier version, uninstalling and completely cleaning Mozilla folders on AppData, deactivating graphics/hardware acceleration...

At one point, Firefox was crashing after ten seconds of watching a video on Youtube or another platform. After reinstallation, video playback no longer causes the browser to crash, but closing a tab does.

I am currently using Mozilla ESR 115.12.0. After reinstalling, I lost all the reports I sent. Nevertheless, I was able to reproduce the crash to give you the ID: [https://crash-stats.mozilla.org/repor.../a2d0f5de-d03f-450b-88f8-a8fdc0240705] Another crash report : [https://crash-stats.mozilla.org/repor.../71c602f6-c682-4158-9880-24d6a0240705]

According to the crash table, the reason for the crash is as follows: EXCEPTION_STACK_BUFFER_OVERRUN / FAST_FAIL_GUARD_ICALL_CHECK_FAILURE This reason appears on all crashes.

Thank you.

Secure connection failed and Firefox did not connect Firefox Last updated: 01/16/2024 39% of users voted this helpful

This article explains why you may see a Secure Connection Failed or a Did Not Connect: Potential Security Issue error page, and what you can do.

   If you see a Warning: Potential Security Risk Ahead error page, see What do the security warning codes mean? and How to troubleshoot security error codes on secure websites.
   To troubleshoot other error messages, see Websites don't load - troubleshoot and fix error messages.

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

Hello, everytime I want to open a website that I frequently use, Firefox fails to suggest it as first and rather suggests the "base" url. Example: I want to open https://www.arabdict.com/en/deutsch-arabisch but typing "ara" in the URL input field always suggests https://www.arabdict.com although the first link is both bookmarked and pinned on home. Can someone tell me how to fix this if it's even fixable yet? Chrome does this if you want to compare the user experience I'm missing since switching to Firefox. Thank you!

P.S: sorry for the first screenshot, I couldn't catch the suggestions menu with the built in screenshot tool.

I'm unable to watch videos on Crunchyroll. When I try to watch a video, the video becomes a static image of one frame. When I switch tabs and come back to the video, or hit refresh, it changes to the latest frame of the video but freezes once again. I have the latest version of Firefox and am using a Macbook. Per suggestions I have found online, I have tried disabling all my extensions, deleting my cache, deleting the Firefox folder in my ~/Library, making sure DRM content is enabled, and uninstalling and reinstalling Firefox altogether. Nothing works. Was hoping to switch over to Firefox since Google Chrome has banned ublock origin, but I keep running into these obnoxious video problems. The same issue also happens on Amazon Prime Video, but only when I press full screen.

Hi, i have problem with uninstalling uBlock Origin i cant remove them from extension tab. I tried refreshing firefox, reinstalling, opening firefox with troubleshoot mode and still nothing i dont know why is so difficult.Even when i reinstalling firefox this addon onstalling by itself even when im not logged in.Please help me. Thanks

I have been trying for a house but won't open, so I tried another Browser and the Email account opened first time. What have I done work or what can I do to fix. Firefox is my #1 Browser. Email removed for privacy

Is there a functionality to view Tabs Side-by-Side, or Vertical yet? Or is there a plan for it; similar to the recent version of Edge Chromium? I have read several questions; and their work-around solutions of using a side bar or sing two windows and arranging them side-by-side. Neither functionality offers synchronized scrolling. I used Tile Tabs or We Tabs add-on in the past which was great.

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt

I've attached images of the problem I'm experiencing. Its like pixels are breaking/turning negative colors and it effects anything visible. I don't really understand what's causing this issue. It doesn't effect any other program on my computer/outside the firefox window, so I assume its a firefox issue. I've uninstalled/reinstalled the program with the refresh to hopefully fix the issue but it didn't work.

Hello, After update to firefox 127 for linux I get popup messages every time I visit a site. A typical message is e.g. for google.com:

www.google.com 1

Any hints? Thanks in advance.

Corel asked me to do a screen shot of the issue: Attached When I look at the changed screen, There is an icon infront of the Web address line that looks like a robot. When I rollover it this statement comes up: Browser is under remote control reason (Dev Tools) All of the address bar is inpink. I copied it but color does not copy. when I did the screen shot the address line is not copied. https://support.mozilla.org/en-US/questions/1449321?utm_campaign=questions-reply&utm_source=notification&utm_medium=email

daThis is still frustrating. I do not like to use the browser when something else appears to be in control. I have MacAFee and run a scan but nothing shows up? If developers are following my browser, I should beable to turn this off.

Webpages don't open on Firefox and a link is clicked (for example, a link in an email). This problem does not happen when using another browser. I followed the advice given to someone who had the same problem. Switching to "No proxy" as suggested did not correct the problem. The advice was from zeroknight and is pasted below: zeroknight 12/1/23, 1:28 AM more options The browser settings are in the menu that looks like three horizontal bars (≡). From there, go into Connection Settings and change "Use system proxy settings" to "No proxy".

Refreshing Firefox did not correct the problem

I want to insert my new IMAP or Pop email box into Outlook. I was already told that this email box@ sophie.johnson@proofreadereditorwriter already exists. I could not get it to show. So I deleted it, and I want to start afresh to install it.
