Why am I receiving repeated warnings from Malwarebytes about blocking every-day websites due to a "Trojan"? The sites include Gmail, Ancestry.com, Newspapers.com and others.

The report warnings are being generated by the Malwarebytes program on my PC. They are confusing to me. I am running Windows 11. The warnings are being logged by the Malwarebytes program in the "Web Protection" section of its "Detection History" web page. In every instance, the log reports are the same: in the URL identification column there is no identification of the URL, only repeated instances of "N/A"; the IP address is identical for all the warnings; the port is always "0"; the file column alternates from "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe" to "System" and back again to "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe"; in the final column of the log, the Date column, the warnings began last evening, Monday the 12th, at 6:50 p.m. and have now extended to to a total nine warnings.

Even as I was writing this communication, the Malwarebytes warning popped up on my screen, telling me that this website and this web page are blocked due to the presence of a Trojan.

Is my PC infected? The Malwarebytes "scan" reports no "detections." I am at a loss.

In the article https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended

https://packages.mozilla.org/apt leads to 404, not a Debian software repository / archive.

Step 4 (is broken)

Next, add the Mozilla APT repository to your sources list:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

I logged into my Firefox Sync account last week on a newly re-imaged computer. My old computer is listed under "Connected Services" and for the first few days, when I selected "Sync" from the top right menu, the subsequent menu included the name of the the old computer and the list of tabs. That list of tabs is no longer listed and I haven't been able to find a way to access it. Attached is an image of the menu where the list of tabs was previously listed. Any suggestions are appreciated.

I think it may be the result of one of the latest Windows updates. I checked the Firefox tabs settings from https://support.mozilla.org/en-US/kb/tab-preferences-and-settings#:~:text=Review%20and%20change%20tab%20settings,correctly%20at%20a%20specific%20size. and they're correct. What am I missing?

It used to show how big and extension was when you would look at that extension, like how many MB it is. Now that is gone and it is almost impossible to find out how much space the add on is taking. Most of these add ons don't have the information even on their websites. What gives? Can we bring this back please? These things are important to know!

Hello. Today I updated Firefox to Version 138.0.3 64 bit and I have found that the Search Bookmarks in Bookmarks no longer works where as in Version 138.0.1 it did. I have done a Refresh and it still does not work. I was wondering if anyone else is experiencing this problem. Is this a bug or something new with the current update. Could someone tell me how to solve this a using the Search Bookmarks function was a big help. Thank you.

Every other day, I open FireFox and may get the following error: XULRunner - This profile was last used with a newer version of this application. Please create a new profile. Also, this error may come up while I already have had FireFox open for a while. Once this error comes up, I check the version, and sometimes the version is older than what it was, meaning, FireFox reverted back to an older version on it's own. I created a new profile, but the error comes back. I removed FireFox and all folders, and the error still comes back. There is nothing I can do to stop the error from showing up again. See attached images. I am on Windows 11 23H2, all windows updates caught up, and the current FireFox browser version is 138.03.

i am quite pissed. i ve been looking for a possibility to ask for help in german language. though i am logged in to the firefox browser i have been constantly asked to log in or create a profil, switched to different pages or just running in circles. quite kafkaesque.

at last i have somehow found this possibility.

i am using firefox browser for a very long time now on different platforms, all my relevant data is saved within.

lately i have realised, that webpages are not loaded properly. after trying the same on chrome, i ve seen, that everything is working fine there.

last example: https://www.aldi-sued.de/de/hilfe-und-kontakt.html

the chat was loading, and didnt get "loaded". in chrome the chat was accessible in a second.

why does this happen? what can be done, to get firefox working as expected?
