For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar.

I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image).

It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window.

Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.

My Firefox browser is up to date but I cannot log on to my Bank website. As soon I enter my Logon info I get logged out, however I can access the site using MS EDGE. This is a recurring problem. The website recognizes Firefox as an valid browser. Occasionally I have been able fix problem by clearing the browser Cookies/History but at present none of that works. Do you have any suggestions? My preferred browser is Firefox so this problem is frustrating.

I am signed into Firefox on desktop and mobile using the same email. I've enabled sync and have synced. Yet my passwords from the mobile browser still don't show on desktop. And the instructions to scan a QR code don't work because they state to click the "sync and save data" option on Android, which doesn't exist for me. How do I sync?

I prefer to open pdf files with the default viewer in the operating system, not on a firefox browser tab. I have gone into settings->general->applications and configured selected "Use system default application" for PDF files. If I click on a pdf file it downloads to my Downloads folder, which is the usual and preferred behaviour. If I click the downloaded files icon on firefox's toolbar, I see the file I downloaded, all good. If I open the folder with all downloaded files, and click on the file, it opens in the OS's default viewer, all good. On the other hand, if I click on the downloaded files icon on firefox's toolbar and simply select the downloaded file from the displayed list, it opens on a firefox browser tab. This is driving me bananas. How do I configure firefox to launch the default system application instead?

Hello, in my "Themes" section in the add-ons manager, I can view all the themes I have downloaded, and there are default ones I did not choose to install/download, and I would really like to disable these recommendations; for these, it only gives me the option "manage" whereas the ones I downloaded I also have the option choose to remove or report. They are not relevant to me, and they take up space and are a distraction from those I am interested in. Is there a way to disable these "Recommended Themes" section???

02/09/2024. For the past 4 or 5 days I've been getting a warning not to proceed any search on Firefox. Here's part of the message: "Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to resultsvlt.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it? The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem. " xfinity is the service provider and I live in Olympia, WA." Please advise.

hi, i have been using mozilla as my default browser for some time. in the past when watching videos i used to press space button to play/pause, the up/down/left/right buttons to increase volume/reduce volume/forward or skip backwards but now none of those are working. what could be the problem??

Since yesterday (12-December-2023) and continuing today (13-Dec-2023) when I attempt to use the search bar to answer a question eg "five letter words with three vowels" I receive the message 503 Service Temporarily Unavailable. I can enter Google and can then go to Google for a search.

For the last few days Firefox asks me to upgrade every time I open it up. If I agree, it appears to do its thing because I get no error messages. Anybody else have this issue? Any suggestions for what to do?

I signed into Firefox on a lab computer that has too little storage space to install plugins (<1MB storage space left.)

Naturally, plugins did not install. I wanted to ensure that Firefox would not even attempt to install them in the future, so I set the browser not to sync add-ons.

I don't know whether what follows is because of that setting, or because I set it too late. In either case, my dozen or so plugins on my main computer have now all been uninstalled. I don't know the names of all the plugins I was using anymore.

1. Can I recover my automatically uninstalled plugins? 2. Can this bug be patched?

I just want to express my frustration.

Today during removal of Firefox (due to bug in Windows "winget" upgrader I got two versions of FF - 122.0 and 122.0.1 so wanted to remove one) I accidentally clicked "Refresh Firefox instead" without knowing what's going to happen in a few seconds.

Soon I was presented with a nice and clean Firefox window with no open tabs, no history and no addons.

I quickly went to my profile folder (%APPDATA%\Mozilla\Firefox\Profiles) only to discover that no full backup was made prior to "refreshing". There were some files preserved - places.sqlite, cookies.sqlite, but no addons, and no sessionstore.jsonlz4. From what I can see, some of the carefully tweaked settings in about:config are also lost.

Fortunately I made my own backup on 10th of October 2023, so I recovered most addons and some of the open tabs. I'm now in the process of restoring other tabs from history. But I like to have them open for weeks or even months, so it's going to take me a lot of time.

The Refresh Firefox thing should be removed because it only destroys data. OR MAKE THE DAMN FULL BACKUP OF THE ENTIRE ***UNTOUCHED*** USER PROFILE ***BEFORE*** REFRESHING IT!!!!!!!!!

You never cease to disappoint, Firefox. Now I'll waste a lot of time to restore what I had before clicking that damn button. And I need to set up a regular profile backup because I cannot trust the software I tried to trust the most... No wonder you're losing users. That is totally unacceptable.

Any clues on how to restore my profile to the state before the "refresh" disaster?

Before, when I started to write an address, firefox did not remember and I have to write it. That was fine. Now, it remembers everything and everything is kept in the history despite I close the private and open it again. Any other person can open the private again and see the last thing you were doing. No real private browsing, no fun
