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

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

In Settings/Applications, have "JNLP file" set to "Use Java(TM) Web Launcher (default)". This is used in Oracle's Agile to view documents. In previous versions of Firefox when selected, the file would open using Java to display the document from Agile. As of Firefox 97, now only "Save File" or "Cancel" options are offered. What happened that this functionality has been removed?

Hi

I don't know what's happened to cause this, but for the last few days if I grab a torrent file online, I only get the option to save the file, no option to automatically open in my torrent client.

I have been to Firefox general settings, and Applications - "Choose how Firefox handles the files you download from the web or the applications you use while browsing" but .torrent is not listed. When I search "torrent" in the Applications search box, I get only "magnet" as a result, nothing for "torrent" files (see image).

Any advice on how to automatically open .torrent files from the web in my torrent client would be appreciated.

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

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.

It seems like something has changed recently, I don't remember having such problem before. As you can see on one of my pictures I have browser settings changed to always ask what to do with every file extension, yet encountering link to pdf file it loaded automaticly in special frame instead of showing just link to it. I included pictures of this frame, settings and another screenshot of the same website in Opera browser with similar settings where nothing loads itself.

Link to the problematic comment with auto-loading pdf: https://kodluch.wordpress.com/2021/09/30/30-09-2021-syria-2187-dzien-sprzatania-swiata/#comment-115906

Is there any way to block such pdf-frames in current version of Firefox?

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.

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.

Who has experienced downloading a PDF file after the last update, Firefox used to open a download dialogue but now it opens the file in same tab instead of downloading it. this can be annoying especially when opening emails and downloading files, every time I have to reopen the same location.

this happened only today after the last update

I am using Windows 10. In other major browsers adding URL's to the taskbar is a simple task. Why is it so difficult in Firefox? Adding them to the desktop is easy but not to the taskbar.

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.

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.

In most standard Windows applications, the title bar and tab colour follows the default Windows settings, e.g. (in my case) the title bar and tab colour of active application windows is blue. This is true even in Thunderbird. Since FF 89, title bar and tabs are something between white and light gray, which is extremely user-un-friendly. FF developer team should return to the previous colour scheme. Yes, I know the circumstances of free software but this is NO excuse to alienate millions of users. Developers that change fully functionable software just, well, just to CHANGE it should consider that they are doing WRONG. Could anyone tell them? I am just user, not developer and I am not willing to learn developer tools like BugZilla just for this simple guiding principle.

I know this page recommends to open the website in a new tab, but I'd like to open it in the current tab. How may I do that?

Apologies if this is a bit limited, during typing it I ran into the issue I'm about to describe which navigated me away from this page and lost all the progress of my post as I was wrapping up :')

The issue I'm having right now is Firefox forcibly opening pages it thinks are a new site in new tabs, despite the site itself not requesting new tabs or windows. Specifically this is happening with sites between different "iterations" of itself while still being the same and having fully integrated layouts and UI.

For example: Most pages on the site have an update "https://www1" prefix, but some pages have the old "https://" only. Firefox keeps opening new tabs when navigating between these different pages despite them being the same website. I know the pages themselves are not sending new tab requests because this doesn't happen in Chrome.

So far, my "solution" has been to go through about:config to adjust the browser.link.open_newwindow value to 1 instead of 3, which forces all links to stay within the same window. This unfortunately causes a whole host of other issues though.

Because its an override, it also means any links opened from an external program (like discord) forcibly open in the last active tab, navigating away from the page. This is obnoxious and annoying in and of itself because it means to save the tabs I already have open I need to manually open a new tab in FF before clicking any link, which I never remember to do. (Goodbye post progress (': )

If that weren't bad enough, when trying to hit the back button to get to the previous page FF ends up in some sort of weird redirection loop "between" pages, where the last page will disappear but FF won't navigate to the link it was trying to open either, so its just a blank infinitely loading page with the URL of the link that was opened. The only way to stop this from happening is to navigate back 2 pages, losing the current page, before it starts the redirect loop. If the loop starts before this happens, the tab locks up and needs to be hard-refreshed with f5 or completely closed due to the weird lag it causes.

Literally all I want Firefox to do here is not assume a new tab needs to be opened just because the URL "seems" different to it. Is there ANY way to get this behavior?

About 3 weeks or so ago I started to have problems using Firefox to open my windows.live.com emails. I can open windows live (it is slow) and all my emails show but if I try to open an inbox email or even a junk email, Firefox tries for a minute or more the gives up and doesn't open the email. I have tried to re-fresh Firefox but that doesn't change anything.

If I use Google Chrome everything works fine.

I am using a Lenovo ThinkPad running Windows 10 Home, Version 20H2

Thanks - pj

Hi - I have been using Kaspersky Password Manager for many months, and it has great autofill capability for many browsers. It has been working great with Firefox, but as of a month or 2 ago... it suddenly stopped working. I checked my extensions and it's no longer there. When I search for Kaspersky extensions... I don't see it anymore. Only "Kaspersky Protection", etc. Does anybody know if the extension isn't available for the current Windows version of Firefox? Of COURSE it works great in the (C-Word... CHROME!) Yuk. Thanks.
