Firefox Support Forum

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

Hi there. I'm in the process of switching from Chrome and I want to import my passwords.

I first tried the 'import from Chrome' option - it says it's successful, but nothing has actually been added. Same result after several attempts.

I then tried the csv route. I found out I had to change the config settings, so I did just that, but the 'import CSV' option still isn't showing even after a reset.

So now I'm at a dead end. Any bright ideas please? TIA!

FYI I'm using Firefox 99.0.1

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

Dear Firefox support,

I am writing to inquiry about bookmarks. I have hundreds of bookmarks, if not thousands with many folders, which I have saved over the last decade. I have always synced my account and it should all be there upon downloading a new firefox on my new computer. However, the HTML file that it is asking me to upload from is not a file I am able to find in by backups, time machine, or anywhere else. It is also not in my account after I sign in. I have spent nearly 10 hours trying to figure this out. I have read all your articles and went through the steps of about:profiles. ALL my bookmarks should have been synced and saved. I have firefox in my Time-machine backup also. But none of the library files populates the bookmarks.

It would be a huge harm to my research career if I am unable to restore my bookmarks. I have trusted and used Firefox for a long time. Please assist me in obtaining these bookmarks in my browser.

Best,

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

Open this url https://openfde.com/intro.mp4 and firefox shows "video can't be player because this file is corrupt".

Chrome is fine.

I am using MacOS Monterey 12.7.1 with the latest Firefox version. When in full screen mode, if I want to refresh the screen I move the mouse pointer to the top of the page to get the tools to display but when I move it down the the refresh button, it quickly hides again before I can refresh the page. Does anyone know of a solution to this or a keyboard shortcut I can use to do a page refresh while in full screen mode?

I've just switched to firefox from brave, and theres no button on twitch to enable picture in picture. Using the keyboard shortcut (cmd+option+shift+]) works, but I'd much rather click something on the screen. On brave there used to be a picture in picture button alongside settings, theatre mode, and fullscreen buttons, but on firefox this has been replaced by a clip button. There's no option for it if I right click (this works on youtube), and no option in the address bar for either twitch or youtube. I've tried disabling all my extensions and lowering protections but nothing seems to work.

Hi Firefox Support,

I was directed to contact you by Metamask Support. I'm experiencing a problem connecting to Metamask from Firefox, though it connects without any issues in Chrome. Based on this, Metamask Support believes the issue may be related to Firefox.

Here's what I've done to troubleshoot so far:

Cleared cache data in Firefox. Verified that I'm using the latest version of Metamask (34.0). Encountered an error when trying to switch networks with the message "unable to connect to Polygon." Confirmed that no other wallets are causing conflicts. I've attached some screenshots for your reference.

Given that I can connect to Metamask in Chrome and have already cleared data in Firefox and ensured I'm using the latest version of Metamask, Metamask Support suggested the problem might lie with Firefox.

Could you please help?

Thank you.

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

I experienced unreadable / garbled / distorted text rendering on some websites on macOS 13.4.1 (22F82).

Tested on following browsers:

• Firefox 114.0.2 (64-bit)
• Firefox Developer Edition 115.0b9 (64-bit)
• Firefox Nightly 116.0a1 (2023-06-30) (64-bit)

See attached screenshot when I visited reStructuredText Quick Reference documentation[1] using a Private Window from a new Firefox Profile.

How can I further investigate or fix this issue?

Firefox has suddenly stopped sizing shipping labels when downloading them from Amazon and ebay. They print way too large. Changing the printer setting, size, etc does not help. It seems as though Firefox is converting them somehow. I have tried clearing the printer settings in Firefox also.

When playing music on music.youtube.com, if I navigate away from the tab, by either moving to a different tab or opening a different application the music pauses. This happens consistently with two different Firefox profiles.

I admittedly have a quite a few plugins installed, so I tested this in a private window and this issue does not occur.

I attempted disabling the obvious plugins UBlock, 'I don't care about cookies', and Tampermonkey without any success. I also tried using a different user-agent without any success.

edit: removed erroneous error information

New York times articles briefly load and then disappear on one iMac. I think it is associated with the fact that the New York Times ads are missing or haven't loaded on that iMac. On our other iMac, New York Times articles load fine and the ads are present. I've looked in the Firefox settings on both and can't find any significant differences differences that would create this problem.

The photos page in OneDrive is having trouble loading most of the time. The page has the OneDrive header, and the section where the photos should show up is simply blank. Screenshot attached.

This is working fine on Google Chrome, but I would prefer not to use chrome for privacy reasons.

Can anyone help me with this?

Regards, Harrison
