Hello,

I just did a full windows defender scan and it turns out Trojan:Script/Wacatac.H!ml popped up when it was done and it said the files affected were:

containerfile: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere

file: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere->(GZip)

I removed the hashes or whatever they were behind the entries, I was wondering if this was a false positive? I didn't notice any slowed down or hacked accounts, also windows defender quarantined it. I've also reinstalled Firefox and deleted all folders associated with Mozilla in AppData.

I did a windows security scan yesterday and it found a trojan in the Users\appdata\local\mozilla\firefox\profiles\c4h...\cache2\entries. Detected: Trojan:Script/wacatac.H!ml.The file is a containerfile. I tried removing it few times but it keeps coming back. This has made me feel uneasy even though I believe it to be a false positive. I've done 3 scans now and it always finds the same file. When I try to look for the file in the folder it's not there, so I can't upload it to virus total.

Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

'Another' Issue With Firefox:

On my desktop, I view Facebook via the Firefox browser. When viewing posts from other people, the date/time stamp is no longer visible.

Instead, it shows a random series of numbers and digits. However, 'hovering' over it displays the date and time.

Refreshing the page does not work. The issue also occurs on Opera.

'Again,' am I missing an 'obvious' detail here?

The website WSJ has large areas on front page, including the opinion listing, are simply white and not 'there' on the page to click on. I've deleted their cookies without effect, tried turning off all adblockers, shut mac down to reboot, nothing seems to have an effect. This is a recent glitch of only several days, prior performance was great. Thanks!

This is the error message I get when I try to connect to different sites:

Secure Connection Failed

An error occurred during a connection to accounts.firefox.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

When I scroll down the page on MSN and try to open a link in a new tab the page jumps back to the top. It then opens a link of another article that I never right/left click on. I have my mouse set up to left click to open a new tab. Does not occur on any other sites.

It has been doing this for months now.

Why can I no longer access my yahoo customized home page. And how can I create a new one, tho I'd rather not have to go thru all of that setup again. Hope you can help me retrieve it. Started yesterday I think.

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

Hello!

Switching between tabs used to be instant. Ever since updating to v133, it takes over a second (both through the Ctrl-Tab shortcut and through clicking on another tab in the tab bar), which is really really bothering me.

The tab bar has also started taking over a second to react visually when I hover over it with the mouse, even with thumbnail previews disabled. I have no idea what's causing this. Please help.

Firefox on MacOS in full screen mode makes the black offset between the screen edge and the Firefox window after logging in after MacOS is locked. It fixes itself when you exit the full screen and enter it again.

How to reproduce?

• Open Firefox and enter the full screen mode
• Close your MacBook and wait until it prompts you for your password or touch id
• The Firefox window has black offset between screen edge and the Firefox window, that was not present before
• Exit the full screen and get into it again, and the offset is gone

logged into mozilla and it ended up in a loop where it kept asking me to turn on caret browsing. every time I hit no it popped right back up immediately. I hit to stop showing the box and clicked no, but now every time I hit the shift key it opens some developer tool box in the bottom of the screen. hitting f7 again does nothing. i can't get the box to come back. i can't make it stop. everything I am seeing online is not helping or references tools or options that i can't locate in firefox. please help.
