READER VIEW icon is missing from the toolbar, and ENTER READER MODE is missing from the VIEW menu, even on sites/pages where it is enabled on my other computer. Firefox version 104.02

Recently I did a full scan with Microsoft defender and it detected a file in the “firefox/profiles../cache2/entries” as a trojan:PowerShell/Meterpreter.A (And also something related to gzip I’m sorry that I didn’t take a screenshot of the message but I completely freaked out and deleted it immediately after scanning with the other AVs). I installed malwarebytes and Avast and did a full scan they returned with a no malware has been detected. In the moment I panicked and immediately deleted the file (I should’ve uploaded to virustotal to see its behavior and what it can do and change to my PC if it is indeed malicious). Then I did a full rescan using Microsoft defender and it returned with a 0 threats found. However, I only went to a couple of websites recently which as far as I know are safe such as msi, cpuid, I don’t go to shady websites plus I have ublock origins as an Adblock. My question is as follows how much percentage wise this Trojan is a false positive and if it is a virus how much damage it did (the thing that got me freaked out is that it’s a meterpreter)

How to import passwords from a CVS file (such as create by Keeper password manager) into Firefox Version 101?

I looked at older questions (example: <<https://support.mozilla.org/en-US/questions/1329981 >>) but the solutions do not apply to the latest Firefox version.

Thank you in advance for your help

I have Firefox Browser version 112.0.1 (64-bit). Firefox says that there is a new update. In order to install the new update it is required to have Administrator privileges in the computer. Until now, to update Firefow, Administrator privileges were not required.

I am unable to sign into Microsoft 365 services in Firefox. When I try to sign in on the Microsoft 365 Website, it doesn't sign in, it simply redirects me back to the website. When I try to sign in from the Outlook login page, I get an error page saying "500 Something went wrong. Repeating redirects detected." Screenshot attached.

1. I was able to sign in with another browser. 2. I was able to sign in on a device running Windows 10. 3. I have cleared the entire cache and history on the Firefox browser - it didn't work. 4. I tried logging in with Firefox in Troubleshooting Mode - it didn't work.

I saw an archived thread from 10/28/2021 where @OthelloBloke had the same issue ("Microsoft 365 Signin on Office.com Doesn't Work After Windows 11 Update"). It didn't seem to have been resolved. It has been a while since Windows 11 came out. Has there been any resolution to this issue? Please help me fix it. Most of my activities are on Microsoft 365, and I prefer to use Firefox as my browser. But if this is ongoing I will need to abandon this browser in order to access my work.

Hi,

I'm using IPv4 as well as IPv6 addresses in my home network. But Firefox uses always the IPv4 connection when I open a website. When I open the same website in MS Edge, the IPv6 connection is used.

I've captured the network traffic during opening a website in Firefox, which is reachable over IPv4 and IPv6. First I see two DNS queries (A and AAAA) for the domain name. Both responses containing the correct IP address, and they arrive nearly at the same time at the client. Next I can see the TCP handshake. But it's send between the IPv4 address only. No IPv6 connection was attempted.

When I run the IPv6 test at https://test-ipv6.com, the IPv6 resuls are nearly fine. Only the web browser test says "Your browser has real working IPv6 address - but is avoiding using it."

When I run the same test in MS Edge, all tests are fine.

So it seems that this is not a OS or network issue. It affects Firefox only.

What I've already tried:

• Disabled all extensions
• Created a new profile
• Used the IPv6 address of the website instead of the FQDN -> Works fine.
• Checked DNS cache of Firefox (about:networking). It contains the IPv4 and IPv6 addresses of the requested websites

I guess that Firefox prefers the A record for some reason. But I've no idea why. Has anybody an idea what could causing this?

Thanks.

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

Occasionally, when I am watching a video on Youtube or Twitch, the video will glitch and cause the browser to go completely white. On Youtube, there will be a small visual glitch and on Twitch, the video will crash and need to be reloaded, but otherwise nothing else happens.

The latest Firefox update appears to break video playback on Linux. I am having issues playing video on Twitter, Facebook, and Locals. YouTube video still plays. I have not enabled any new ad blocking and have also not changed any settings. Looking at the Troubleshooting Information in Firefox reveals nothing that is suspect.

The google search bar on the homepage doesn't work, just does an infinite load, the same with google.com. The extensions I have are AVG Online Security, Malwarebytes, and AVG Anti-Tracking. The version is the latest version 116.0.1

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

I've worked with Firefox for several years, and had it opening maximized. I recently manually resized the Firefox window to facilitate some work in which I needed some other windows visible. However, now I can't get Firefox to open maximized. Instead, it opens a window going from the left edge of my screen (see the first image below) about a third of the width of the monitor, and it is showing the double box icon in the upper right corner indicating that the computer "thinks" it is in full screen. If I click that double box, the window immediately shifts to the right edge of the screen, occupying a space about a third of the monitor from the right edge, and shows a single box in the upper right corner of the window. If I click that single box, the window finally does expand to full screen, showing a double box in the upper right corner. I've tried all the manipulations I've seen concerning starting screen size (such as going to the shortcut icon properties and indicating the that the program should start "maximized") but I'm still getting this same behavior. Any thoughts? (I'm running Windows 11, with the latest version of Firefox.)

Hi. After recent update I started to see issue where blue/white border is present when clicking web site elements. Ususally this kind of border is present if you select elements via keybaord but in this case it's present when clicking elements with mouse. It usually stop doing this if I close and reopen FF but not for long. Example is in posted screenshot. I have not altered my settings in any way.

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

For the recent past, the font size on FF tabs, url, bookmark bar, tabs and anything else to do with the actual FF program has a font so small that it is unreadable unless I use the W10 magnifier. I have spent hours, days and weeks trying everything I can find to increase the font size and nothing has worked. I am vision impaired and understand that everything cannot be adjusted to my needs BUT there are hundreds of postings on line by people with good vision complaining about the non adjustable font sizes. Does FF have any intentions on finding a fix for this? I am an avid user of FF but am at a point with my vision to where it is too problematic for me to continue using. If you cannot fix this issue then I must find a program that does not have this problem. It may very well be a conflict between FF and W10 but even that were the case, there are supposed to be a lot of intellingent individuals that should be able to remedy this situation. Please advise of your intentions as soon as possible in order that I may proceed with my plans. Sincerely, Ron Burnes

Certain fonts are displayed not as what I set them to in Firefox's settings.

At first, I thought it was a windows OS font related issue- it's not.

I've followed everything here: https://support.mozilla.org/en-US/questions/1323130 (The answer support link is inaccessible. But following the answer did not fix my issue.)

Also looked to see if any of my add-ons are affecting it. I've disabled them on the sites (in the screenshot) but the fonts are still displayed as attached. Checked to see if the add-on uBLOCK is disabling remote fonts, that feature is not checked so that's not the issue.

Please help, thank you.

Using Firefox version 102:

Open console tools and navigate to Network tab Right click on a POST request "Edit and Resend" is no longer an option? There is still the resend option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to?

Thank you.
