I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

In Chrome, I can search a full PDF whether I view it within an email, or as a PDF opened in the browser.

In Firefox, I can only do the latter - I can search the full PDF if the PDF is open in its own tab after being downloaded, but I cannot search the full PDF in the Outlook preview.

I do this every day for work, so this is a bit of a deal breaker if I'm unable to find a workaround. Does anyone have any ideas on how I can get around this?

I take guitar lessons on line and the audio for the lessons has suddenly defaulted to muted and I can't unmute it even with repeated attempts. The speaker icon is x-d out. I've rebooted, gone out and back in to the site and tried it on another browser where it worked fine. Firefox is my preferred. What can I do?

Windows Defender uninstalled the Firefox browser because of a Severe security threat. Is there a threat to installing and using the Firefox application on Windows 11?

Hello! Appreciate the help I could get. It is rather hard to type when the letters are disappearing as I type it out. I will provide screenshots of my issues and hopefully someone could help me out. I just downloaded the browser and have no idea how to fix the issues. The tabs are constantly flickering in different colors. The letter are disappearing or merging together or sometimes written in bold, crossed out, or underlined. It is making it rather hard to use the browser haha, but let me know what else I can provide to help out identify the issue. THANKS!

I need to call an executable script that I wrote when I click on a link to a file of a certain file type. I used to be able to browse to my script in order to set it as the desired application, but now I can't find any way to persuade Firefox to call my script when, for example, the linked-to file's name ends in '.dng'. Where is the list of such applications, and how do I add my script to it?

Choosing, "Sync now" as usual on both Android and iMac does nothing. in Firefox, putting the phone up to the bar code does nothing, except it now tells me I can't use my camera (my camera works).

I know every company feels the need to change settings for no reason, and make things confusing in each update, but this is extreme and has never been a problem before between these two devices.

I have no viruses as I regularly run scans.

Does anyone have updated directions on how to keep the same bookmarks, which is on the only Mozilla account I have, on these two devices?

I recently re-installed FireFox after I suddenly had problems that the profile folder could not be accessed. I uninstalled it, then reinstalled it using the download from Mozilla website. This fixed the profile issue. I am using the latest version. Now, I find that most of the time, cnn.com won't load: I see messages on the bottom left corner that it is connecting to all sorts of web sites, in particular it tends to get stuck on "Sending request to signal-metrics-collector-beta.s-onetag.com" . I don't know if it eventually loads, I give up after about 1 minute. In Chrome, cnn.com loads instantly. In Firefox, BBC.com loads instantly. Microsoft.com loads instantly. I have installed the same extensions as before. I started FireFox with all of them turned off, no difference. As I mentioned, it does not load MOST of the time - once in a while it loads instantly, but later on the problem reoccurs. >What is wrong with FireFox and why won't it load CNN as quickly as before? I am using Firefox on Windows 11, I have Malwarebyes installed. Thanks, Adriaan

This file has 0 bytes and it had random letters/numbers dot HTM I "opened" the file in browser but it opened to a dead/unable to load page that was titled in the format of Computer Name>Downloads>NameOfFile or something like that.

I've ran anti virus/ malware bytes, windows defender but I don't feel safe.

What is this file and why did it download?

I'm on firefox 10 with Privacy Badger but not enabled.

Any help would be appreciated. I get paranoid of viruses/malware and what does this mean for tracking/did someone download files on my computer etc

Thank you

Hello, I have been aware of this issue for about a month now. I have, for example, added 3 sites to my "Block" list under "Manage Exceptions" in "Cookies and Site Data". They are not only repeatedly disappearing from the exceptions list without my input (which I suppose is the bigger issue), but even when they are present, the websites still end up storing cookies and site data for the session. These sites are Wikipedia, Bing, and DuckDuckGo.

In addition, I've also added a finance website to the "Allow" list, as the browser is set to delete cookies on quit. This website has also repeatedly disappeared from the exceptions list without my input.

My version of Firefox updates regularly via the Linux Update manager. I am also wondering if the "Forget about this site" option in the History menu generates this (at least to me) unexpected behaviour. I would expect that using the "Forget about this site" option would delete site data, cookies, and history, but not remove it from my Cookies exception list...

Hi there I am using Firefox version 140.0.4 (64 bit) have recently started to backup my profile on my Windows 10 PC using a small batch file and Winzip. However I have noticed that some, probably four, of the files within the profile folder are not backing up and Winzip says it could not open them for reading. I believe that the profile is stored at C:\Users\Phil\AppData\Roaming\Mozilla\Firefox\Profiles\*.* and this path is included in the BACKUP.LST for Winzip. Omitting this line from the BACKUP.LST gives no errors so I am convinced it is a Firefox problem. I have also noticed that after a clean, hard boot one of my housekeeping programs, SuperAntispyware, thinks that a browser is open and wants to close it before running. I always backup immediately after a clean, hard boot so nothing should be open on the PC except the batch file and Winzip. I do not have Firefox in my list of Startup files. It seems to me that some of the Firefox profile files are somehow opened immediately after booting and I'm wondering if there is a setting that I've missed which will cause this. In the general settings for Firefox, the option to "Open Firefox automatically when your computer starts up" is unchecked. Incidentally, I have also run the daily backup under WinRAR and get a similar error message. Any comments / suggestions will be gratefully received. Regards and TIA Phil
