WidevineCdm plug-in crashes everytime when I try to play disney plus or amazon prime. I fit the requirements via the disney plus site. Can anyone assist? I was streaming fine last week and now its not working.

Hello,

I have the site espn.com bookmarked and for the last month or so it has been opening it's various foreign sites instead of the united states version when I click on the bookmark tab. It will switch to the UK and Mexico sites randomly when I click on the tab. The address is saved as the US version (espn.com) when this happens so I can't figure out why it's doing it. It doesn't matter if I use a vpn that says I'm in the US or just my regular internet provider in the US, the site keeps changing what country it chooses to open with. I noticed that every time I click the tab it will cycle between the various different sites for each country even though as I said before, the bookmark is set for espn.com. It makes no sense as none of my other bookmarks do this and it doesn't do it when I use Safari's browser. Is there anything on my end I can do to get this to stop or is it coming from espn.com's end? Thank you for your time and help. :)

Since I updated to Firefox v.91.0 I get this error:

Secure Connection Failed

• An error occurred during a connection to support.mozilla.org. PR_CONNECT_RESET_ERROR

• 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.

when ever I try to connect to websites via Firefox only. I've tried many things like reinstalling Firefox and I know its an issue between Firefox and my Antivirus (Kaspersky,) but this didn't happen before Firefox updated to v.19.0 though. I've tried https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and many other things but nothing works to fix it. I've switched certificate stores and other 'fixes' I've read on this website and others to no avail. It does this with or without any extensions in Firefox.

This only started when I updated Firefox to version 91.0. It doesn't give an errors/issues on any other browser I've tried so far (MS Edge and Chrome) so must be something with the version 91.0 update?

Any ideas to fix this would be great. Thanks!

Please help, I just screwed up so bad I accidentally pressed the red "close" button on Firefox on my Mac instead of the yellow "minimise" button and lost a bunch of tabs I need (they were from a while back so not in history)

There is no option to "restore previous session" or "reopen tabs" is there any way whatsoever to recover my lost tabs I am freaking out big time there was some really important stuff in there that I hadn't bookmarked yet like an absolute IDIOT!!! My session had stayed active through computer being shut down and restarted and Firefox updates but pressing the red "close" button has seemingly nuked it. Is there a way to go into folders and find the tabs? Anything please help :(

Any help appreciated, I'm desperate.

Hello, I have folder with old Firefox data, I need Google account name and password, mostly name. How can i decrypt the name from file logins.json or how can I import it to my current Firefox profile? In properties of passwords in Firefox I don't have option to import from file, I don't know how to find option that will let me do it.

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

I'm a little surprised they've taken away the option of choice when it comes to downloading files. But what's most annoying, is the manager opens u and drops down blocking my view of the page, much less that it makes ms stop and think about what I am about to download.

I do not understand the purpose of this. The old way was safer, cleaner and less annoying. How can, or am I able to get that "choice" back?

When searching for a fix I have seen that that there is/was a similar feature in the Edge browser but it can be undone. I feel Firefox users deserve that option.

Thank you.

Thank you.

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

My tab bar and menu bar background is white. I have the latest FF version and I hear it should be black but it isn't. It used to be but I may have changed something and lost it?

How do I make it black for ease of visibility - but not the web pages (just the upper bars). I have searched for hours and none of the answers either match what to do, or work.

Hello. After reading numerous posts addressing similar issues & having no success, I've decided to post a question of my own. I am running the current version of firefox, 94.0.2. I use the Search Bar religiously for searches to sites like google, wikipedia, youtube, amazon, and ebay. I NEVER use the address bar for searches. I have attempted to disable all functionality associated with searching via the address bar. When I go to the address bar, it is because I have a specifc url I know I want to type with a specific destination in mind. Occasionally, I have a need to just go to the home page of one of my search sites, most often it's amazon.com. Recently (not sure which version of firefox) I've found when I go to the Address Bar & type amazon.com, I cannot just go to amazon.com, instead the address bar turns into a search bar. How do I disable this? Its driving me mad! I swear I've disabled every option I can within about:config related to urlb. Please Help. I don't want to switch to Chrome, but I'm tired of my settings getting messed up every time mozilla pushes a new version.

This "half-answer" summarizes my frustration. FWIW, both computers are late-model MacBook Pro - call them Mac1 and Mac2. Both have Sync set up. I have about 40 tabs open in 3 FF windows on Mac1. I need to open all 40 tabs (which can all be in one window if that's easier) on Mac2.

On Mac 2, I can see the list of open tabs from Mac1 when I click the account name (after clicking the "hamburger patties"). If I click on one of them, that tab is opened on the current tab... terrific - BUT, I don't want to repeat this 40 times!!

Is there no way to select ALL tabs, or export all open tabs to a file - or something that makes a little more sense than repeating a task 40 times?

I followed your help line however, on firefox version 94 there is no "Import from a csv file" for logins and passwords. I am migrating from a PC to a new laptop. I created the csv file from the old PC however, I am unable to import that data onto the new laptop.

I am running version 94.0.2 64bit Win10. Can you provide a solution as this is very frustrating.

Thanks A

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.

British English Spell Check as you type is no longer reliable, sometimes it works but most times it doesn't. Can't seem to get to the bottom of the problem, all settings are correct but still doesn't work properly.

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

I am having problems with doing downloads of any files from any website using Firefox. Every time, when I try to do a download, I get an error that the download failed. I am running Firefox 98.0.2 on a Windows 10 laptop. If I use Microsoft Edge, the download is successful. Any help would be appreciated.

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.
