Firefox Support Forum

I've just done a clean install of Windows 11 12H2 and, consquently, FireFox.

Don't know why I'm loosing all cookies when Firefox session ended.

Firefox 101.0.1 x64 OS Windows 11 Pro v 21H2 (Build 22000.776)

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

I am trying to download a spreadsheet file which has a .xlsx extension. Firefox insists on downloading the file (my default action) but I want to be given the option to open in my spreadsheet program (Libreoffice).

Looking in Settings and scrolling down to Files and Applications -> Applications, there are other spreadsheet formats present but not one for .xlsx. How do I add the "Always Ask" option for .xlsx files?

Libreoffice is the default system application for opening these files.

I first thought this issue was contained to a single website and was the fault of their IT, but I have begun to experience this issue on other websites, and it does not occur on other devices also using Firefox. It is difficult to explain given that I don't have any idea what is actually happening, but hopefully I can make it clear enough.

For some websites that require a username and password, I will correctly login and pass authentication but then I will be booted back to the initial login screen, almost like the login failed. I only know that it is technically a log out, not a failure, because I have briefly seen the URL change like I'm logging out. I have tried uninstalling and reinstalling Firefox fresh multiple times on my Windows 11 laptop, but the same issue occurs consistently.

This happened when I was trying to login to the student portal for my university and when I was trying to login to my apartment's resident portal. Changing cookie settings or going into a private browser has not helped at all. I cannot tell if this is a bug with Firefox (maybe just on Windows 11?) or if there is some background setting that needs to be adjusted, but it is very frustrating. If this keeps happening, I would have to switch to a different browser, which would not be ideal.

Does anyone have any idea of steps that I could take for troubleshooting or any experience with similar issues? Any help would be greatly appreciated.

Firefox 101.0.1 + extensions, Windows 11 22H2; both fully updated

Firefox has stopped saving the position of its window, looking to me like it is leaving space for my Windows taskbar but which is hidden.

Some online searching and I found that setting privacy.resistFingerprinting to false resolves the issue, but it is not a change I feel comfortable with and wonder if there is another solution. I have uBlock Origin installed so maybe I shouldn't be concerned.

I keep trying to add Honey extension using Firefox. It shows that I have downloaded the extension, but it is not working. I know I am doing something wrong, but I don't know what it is. Thank you!

When on Firefox, I sometimes fill out a form on a website for a variety of reasons, i.e. requesting a document. After doing so, I can find no record that it was sent. My primary email is [edited email from public] @gmail.com. Is that what is used to send it? If so, I cannot find any record of it when I check "sent" items on that account. Please tell me where i can find that record? Steve C

Please see the attached screen shot. The icons at the top which allow you to toggle between watchlists are not available, and if you look at the list of stocks, some say "Equalizer" instead of showing the icon. Any settings I need to check?

I started up my computer today; I tried to open up a youtube video in picture-in-picture add-on, but it wasn't there. I restarted my computer, completely closed firefox, looked into settings for the picture-in-picture settings that are supposed to be under 'Browsing' in General but I can't find the settings for it there either. I have tried using other video sites, but nothing works.

My old 2009 MacBook Pro broke, got fixed, and now the backup won't transfer. So I need a new Firefox.

OS X El Capitan V10.11.6 is the latest this old computer will handle. On the mozilla.org download page, the app on the .dmg that gets downloaded says it wants OS X 10.12 or later.

I'd appreciate your suggestions.

When I look up the error message I get, everyone I see who got it can't open Firefox, but I can open it fine. For me, I have Firefox as my default browser and when another program (tModLoader on Steam) tries to open it, it gives me "Profile Missing," "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I don't know if it gives the same error for other programs because I can't think of any programs that open my default browser. When I switch my default browser to Edge, the program can open Edge fine.

Hello

After the latest Firefox update, 101.0 (64-Bit) for Windows, the text of our website can't be read anymore because it suddenly appears way too bright.

It worked since years before and still works with other browsers.

Is this a know bug with version 101 and might be fixed? Or is there any other problem?

The website is: link text

Thanks a lot, if someone can help!

Kind regards,

Wolfgang

I reset my privacy settings to "standard", as they were causing too many problems. I quit Firefox. Some websites (like Google) are still telling me that cookies are disabled, when they are not and don't allow me to go to these websites. I attached 2 screen captures. Any reason for this and how to fix this problem?

Thanks.

Firefox has become very slow for some two weeks om my desktop with Linux Xubuntu 18.04. Some sites can be approached without problems except for the speed, other sites are opened after some time, but freeze so that scrolling and clicking on links won't work. I tried to find an answer in the Settings......

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

Hi dear managers, First of all please delete this duplicate question because of mistake about links : Admin please Delete this... In Windows 10 & Firefox 101.0 youtube is like below before login to youtube account : Before Login After login to my account in youtube it looks like this : After Login I checked it with another account - same problem.

Hi,

I am trying to connect my device to a web page crypto wallet and get this message/prompt: Windows security Making sure it's you Please sign in to https://wallet.thetatoken.org This request comes from Firefox, published by Mozilla Corporation

Insert your security key into the USB port, I bought a security key but do not know what they are asking for?

Can anyone help......

Hello, I experience a XUL Runner error message after attempting to update Firefox and in following the guidance to rectify the error deleted the Firefox folder including the bookmarks. Is there anyway of recovering the bookmarks (maybe with a third party program) or are they lost forever? Thank you.

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?
