I can't seem to disable the certificate verification on Mozilla Firefox. As you can see on the screenshot, the error code is SEC_ERROR_UNKNOWN_ISSUER.

I tried multiple solutions, including :

- https://smallbusiness.chron.com/disable-firefox-rejecting-certificates-59249.html - The three solutions from https://stackoverflow.com/questions/20088/is-there-a-way-to-make-firefox-ignore-invalid-ssl-certificates - https://support.mozilla.org/en-US/questions/1234483 - All of the solutions from https://browserhow.com/how-to-fix-mozilla-firefox-ssl-certificate-error/ - https://itectec.com/superuser/how-to-make-firefox-ignore-all-ssl-certification-errors/

and so on.

Is there a way to disable this for only one website, or at least for all website ? I got a web interface which is self signed (if I understand everything correctly) where we can bypass the certificate "error" but it would be great if I just could configure Firefox to skip it entirely for this interface (as I'm certain it's not insecure and even if it was I'd still use it because I can't use anything else for now.

I know Chrome has a command line which do exactly what I want (--ignore-certificate-errors) but Firefox is a must go for me so I'd prefer to find an option on this browser.

Thank you for your time.

Hi, I can't install Firefox and I don't know what's going on here.

Yesterday I installed the latest version of Firefox and it worked fine. Then, I turned off the laptop and the next day when I was going to use Firefox, it didn't load any pages. Edge was working fine, Chrome was working fine, but Firefox was not working. Trying to fix the problem, I decided to uninstall Firefox and installing it again. In order to clean even more the previous installation, I even manually deleted the C:\Program Files\Mozilla Firefox folder to remove all possible traces. I restarted the laptop and downloaded again the Firefox installer. I don't know how, but the installer detected that I had already installed Firefox before. I unchecked restart Firefox and hit the button to continue with the installation. After this, was impossible to install Firefox again. I got a message saying that the installation cannot continue because the VCRUNTIME140_1.dll was not found. The message said that this problem can be fixed by reinstalling the program, but that is not true, everytime I try to reinstall it, I get again the VCRUNTIME140_1.dll error.

After this, the installation stops and the Firefox icon appears on the desktop, but it doesn't install properly the software and when I open it, I cannot browse the Internet.

Do you know what's going on here and how to solve this?

Cheers

Alright, basically I backed up my PC before I wiped it. Then decided to move from chrome to firefox. But there is an issue, I can't migrate my passwords because google chrome will not read my old LOGIN DATA file and refuses to create a CSV either. So basically I can't import about a decade worth of passwords into firefox because of a flaw in chrome's design, fantastic.

So I thought, well, surely if there are program that let you read SQL files (such as the LOGIN DATA file) if you have the password, firefox must be able to do this to right? Well no. Apparently not.

I am not sure if this is the correct place to formally request a QoL feature but I would really, REALLY, like to be able to import my passwords directly from chrome's LOGIN DATA file, I have the master password.

It was my mistake to back up my files thinking that would be enough, I should have known better and double checked if chrome could not read its own native files. But now im screwed. Help. Please.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nextechclassifieds.com because this website requires a secure connection. www.nextechclassifieds.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. www.nextechclassifieds.com uses an invalid security certificate.

The certificate is not trusted because it is self-signed.
Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

This is a trusted website, been using it for years without issue. Used it a few hours ago to check my account. Only problem is on my pc, all other devices including people I've asked, do not have this issue. Seems to be a problem with the firefox browser only.

Firefox icon gone from taskbar and desktop and I can't get it back

As the subject says. I can still search for the firefox app and open it that way or I can start it from the START page that comes up when I hit the windows key on the keyboard. But I am not allowed to drag and drop it onto the taskbar as it says it's already there. It's sorta there I guess because FF is open right now while I type this and this open tab is indicated on the taskbar. If I were to close the FF window there would be no FF logo on the taskbar.

Right clicking the firefox app in the start list that comes up when I left click on the windows icon in the lower left or hit the windows key on my keypad gives me options to unpin FF from the start page or unpin it from the taskbar. I don't want to do that.

I did something to mess this up and I can't fix it. I want the FF logo back on my taskbar so when I power up the machine I can click on the logo in the taskbar to get to the browser with all my previously open tabs back.

The latest Windows 10 a Lenovo yoga laptop if it matters.

Thanks

A recent Firefox update has totally disrupted our ability to print from browser windows. There used to be a "Print Preview" button that allowed us to set things up the way we wanted them. That's now missing. As a result, stuff that used to cost us for ten pages now costs us for twenty pages. Also, when we print double-sided, the second side prints upside down.

This strikes me and my wife as a horrible development, and we would like to go back to the old version ASAP!

I need to use Google Meet for a professional purpose. When I use is from the Chrome browser, I can present a specific tab on my desktop; however, I prefer to use Firefox as my default Browser. The problem is, when I use Meet on Firefox, the presentation options don't include sharing a tab. Is there a way to fix this, or do I just need to use Chrome when meeting?

Thank you.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?
