My FF Browser introduced a vertical row of rings which I want to get rid off. Im using W10 and FF Version 151.0.4 (64-Bit). Rings are stable, updates show them again. Any Help???

Moderator note: Moved from the Firefox for Android forum to the Firefox Desktop forum.

Auto updated to firefox 150 yesterday. What's new screen announced the rollout of the free in browser vpn had reached us (in Canada). Clicked the link to set up, went to screen to follow instructions. There's no vpn icon in the firefox menu bar, no matter what I do. (And I have done everything obvious.) Was the VPN not in the actual update I received or is this some bug/glitch? Thanks.

The details:

1.) After downloading the update, my antivirus scanner reports an infected file (see screenshots / message + path).

2.) When I try to “Restart Firefox to complete the update,” Firefox briefly “disappears” (whatever happens there) and then “reappears”—but the prompt “Restart Firefox to complete the update” is still there. Unfortunately, this can be repeated as many times as you like without anything changing.

3.) Restarting the computer (Platform: macOS Tahoe 26.5.1) does not resolve the issue either (see screenshot). I always performed previous updates before shutting down the computer—and the next day (since Firefox, as expected, had been closed and restarted), the updated version of Firefox was running.

4.) The suggested solution is to download the “Firefox installer.” But that doesn’t help me, since I need “Firefox DEVELOPER.”

Would uninstalling Firefox DEVELOPER and reinstalling it >WITHOUT DATA LOSS< be a solution??

I CANNOT log into my Facebook account since Firefox launched your VPN. I didn't sign UP for the VPN but I'm troubleshooting and the VPN launch happened at the same time I was denied access to Facebook. Can you FIX this problem????? It is infuriating!!!! I can SEE the page and friends can SEE the page which means it hasn't be LOCKED or deleted. I just can't access my own page - not with my phone # or email. I just get a 2-step authentication notice EVERY TIME I try to login and when I do try to log in, I get the "technical issue" notice. My page - https://www.facebook.com/SueCastner

I have been working on this since SUNDAY and I am the Press/Media liaison for a number of organizations. This SNAFU is going to get me fired if I can't get back on social media! There's GOT to be someone in your organization who can connect me with an actual human being to FIX THIS!!! PLEASE

I have installed Firefox VPN, but it is disabled by default so I have to enable it whenever I use it . How can I change the default setting to make it on by default

How would one purge their cookies, search history, tab data while resetting/randomising identifiable information (for example if Firefox were to give each user a serial number or unique tag which it hands to webpages), all without resetting a users a user's browser settings, about:config & browser extensions downloaded (and extension settings). I am using Debian GNU/Linux, so bear in mind that I will be using the most stable version of Firefox on the Debian repos, not the newest version. I do not have a command line phobia, I am willing to do a lot of initial setup & run a specific command every time I launch the browser, even if said command is long. My current system involves rm -rfing the profile on a browser, but this is not optimal because it removes settings & extensions.

Thank you verry much for your assistance, I know this is a large undertaking and it a little overboard on the privacy and security front.

I have several saved cards in 152.0.1 (64-bit). When on a payment site the drop-down list shows up as expected, so the extensions.formautofill.creditCards.supportedCountries is correct and working (GB). Also address filling still works, as does saved passwords,

However if I try to "Manage payment methods" the resulting list in "about:preferences#managePayments" is blank. (see image)

I have tried toggling on and off "save & autofill" and restarting, but nothing helps.

Adding a new card works, and the new card appears in the drop-down list on a payment form, but still nothing appears to edit or remove in the settings. How an I edit this list?

PS: I have disabled ALL extensions.

Whenever I have just 1 Window of Firefox and just 1 tab open, task manager ALWAYS shows 14. Why is this? I have refreshed Firefox and lost some of my settings, it did nothing. Have I been hacked and someone else is controlling my browser?

Screenshot shows one firefox with one tab and yet 14 next to it in Task Manager

I found some information about deleting closed tabs from Firefox.

Please allow users to select a date or date range instead of a maximum number of tabs and windows. Computers often restart, for instance when installing updates, and some sessions will include more tabs than others.

Thanks in advance!

Some how someone has attached to my computer and its system or programs, accounts Etc... Im not entirely sure, I am Looking for anything that I can Install or Add-On, Download or Extension's, Whatever Could Help Deep Search and Locate the Root Cause or Area where they were able to attach to my Files or whatever it is they latched onto.

After realizing what was being done to my PC, I unplugged it to stop the hacker. And I have since been able to recover my program, except for my ad blocker. Before this unusual encounter, I was using a free ad blocker. I want to restore it to its original status, if possible. Thank you for any help, Leman H Wilson at 7:09 PM 6-3-26

Recently found one way to delete closed tab/window record: set both to zero.

Please allow users to select a timeframe as well. People may have to restart a computer while in private mode, and a set number of tabs/windows cannot cover all possible situations.

Thanks!

I asked a question last night about whether or not Firefox had an IP Address. Sounded silly, but I was dealing with an unfamiliar IP. I did eventually find apps that locate IP Addresses. Problem solved . Just want to thank James for taking the time to respond to my question.

Hi I'm running Firefox 152.0.1, 64 bit, english version from Italy. From last updates I learned that a built-in VPN is available for users. I looked for it everywhere in Firefox toolbars and menus, but I cannot find it. Am I stupid or VPN can be unavailable in my local version of Firefox? Thanks!
