Firefox Support Forum

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.

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.

Firefox has been awesome. But, my computer just updated to windows 11 and now it doesn't work. Sometimes I try to open the browser and nothing happens (but I somehow end up with something like 7 instances of it running in the background, according to task manager), sometimes I get it to open, but it won't load my homepage or anything, and sometimes it seems to work fine but only for a little while - then it just stops responding.

I have no idea why this is happening or how to fix it. I tried the browser reset, which helped for a little bit but then the problems came back. I think having a theme installed makes it worse, but now I can't even get settings to open so I can try turning it off to see if that helps.

Any ideas? Not being able to use the internet on my computer is a pretty big deal. I'd prefer to not switch browsers, but I don't know what other option I've got at the moment.

Thanks!

Firefox updated. After updating, whenever I try and load Firefox, I receive the following error message:

"XULRunner

"Error: Platform version '91.0.2' is not compatible with "minVersion > = 91.0 "maxVersion < = 91.0"

I click, "OK" to confirm... and Firefox closes. When I try to update Firefox once more, I receive no response from teh System. When I try to load MaintanceService, I receive no response. What's teh deal here. Any answers?

I, today, found that Firefox 88.0.1(64bit) sends "/nice%20ports%2C/Tri%6Eity.txt%2ebak" to an website. What is this? Am I infected? The Apache log at the HTTP server is as follows:

192.168.1.188 - - [10/May/2021:07:42:41 +0900] "GET / HTTP/1.1" 200 665 "-" "Mozilla/5.0" xps8940 192.168.1.188 - - [10/May/2021:07:42:42 +0900] "GET /nice%20ports%2C/Tri%6Eity.txt%2ebak HTTP/1.0" 403 - "-" "-" 192.168.1.188 192.168.1.188 - - [10/May/2021:07:42:42 +0900] "GET / HTTP/1.0" 403 - "-" "-" 192.168.1.188 192.168.1.188 - - [10/May/2021:07:43:58 +0900] "GET /Picture/MicroS5S.gif HTTP/1.1" 200 3042 "http://wista.jp/Index.htm" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0" xps8940

The server is located within my home LAN. 192.168.1.188 and xps8940 is the captioned machine that sends this unknown protocol. Tested by Chrome and found no such protocol sent. Could any guru enlighten me? Tak

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 using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

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?

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 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.

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.

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.

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 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

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 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.

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 got a new Lenovo Laptop and cant get Firefox to load a webpage. Here's what happens and what I've done 1. I install Firefox and during install get error below, VCRUNTIME140_1.dll Not Found. I then click OK and Firefox Installs but when I load it no webpages will come up just a black screen no indications it is even trying to load the page, no error message. It does nothing. Cant even open Google.com 2. I looked in MS forums and they say to install Visual C++. Did every x86 and X64 version I could find. Still have the problem even after uninstalling Firefox and reboot. 3 Have McAfee, and took Firefox off the Safe list then put it back on. 4. Went to try and find the file but can't on a reputable website. So I looked for this file on my Dell Laptop and Asus Desktop. Both have Firefox installed and it works fine. Get this, NONE of my other two computers have that exact file name anywhere. VCRUNTIME140_1.DLL! They have 140.DLL and a few other 140.dll with different variation but no 140_1.dll? So how does Firefox run on 2 other computers without this DLL but not on this new one? They are all Windows 10 Would appreciate any help. Seems to be a Firefox or Lenovo Issue just not sure. If anyone know how to get the DLL from MS let me know.

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. :)
