Firefox Support Forum

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.

Firefox says that it is now my default browser, which is what I wanted, but my browser is still duckduckgo, and firefox browser is not on the available list of browsers to select as default. I downloaded it. I selected "make it my default browser". But it isn't. It's still duckduckgo.

Currently the fonts at the top of the page (tab headers, address bar, search bar, booksmarks) are all set to a larger font. I don't know how they got changed but they are too big now. If I try change font size and style in settings nothing happens. It is not how it looked on first install and using another browser has font sizes of a more practical size. I have tried uninstalling/reinstalling Firebox and also doing a refresh and it doesn't change anything.

Its almost like a bug that has made Firefox set these fonts larger than they should and not able to modifying them again.

I cannot for the life of me work out how to fix this and its very off putting to the point, short of a full OS reinstall I'll have to start using another browser.

"Sorry, the video player failed to load.(Error Code: 101104)" - this error message happens on some sites but not others. I believe there are more than one type of streaming transmission but do not know how to determine which is failing. For example, the streaming daily report on Democracynow.org fails while the reports on http://www.bbc.com/news/video_and_audio/international does not. This has been a problem for weeks now. I view both of these sites every day but must now use Microsoft Edge (ugh) to view democracynow.org.

I am no longer able to copy and paste an article in its original format. I no longer can copy and paste any image, including copying and pasting screenshots, without them going into attachments. I know this is not a google issue because my wife uses chrome-which I do not like-and I can copy and paste articles and images accurately on chrome. I do not wish to use chrome, or upgrade to windows 11. I have tried refreshing firefox, uninstalling and re-installing to default settings, and nothing works to restore this ability to me in firefox.

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?

I would like Firefox to remember exceptions and store specific cookies that I need for the Microsoft authenticator, and other two-stage logins. Whatever setting I choose (untick delete cookiex and sitedata, assign websites to manage exceptions etc) upon closing Firefox everything is deleted, always. This means I can't use any authenticator to remember me when I want it to do so.

I used a third party cookie extension (Cookie AutoDelete) to whitelist some sites and it worked perfectly fine until an apparent recent update by Firefox. I am on Firefox 101.0.1 on Mac.

Any ideas?

I entered my password accidentally into the username field on a webmail page. It keeps showing several entries I made in the past every time I log in. How do I get rid of these entries? I searched the subject and all the suggestions of deleting it in the dropdown box with SHIFT+DELETE or CTRL+DELETE don't work.

I also use Vivaldi browser and I have the same issue when logging in to webmail. The list of usernames is different from Firefox so I know the lists are tied to the particular browser. I was able to delete the entire list with Vivaldi and I logged in to webmail and auto-fill list is gone. Can't do the same in Firefox. Please help.

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?

I just upgraded to Monterey on my Mac running FF 101.0.1 (64-bit). I cannot add new search engines to my list of search engines. I'm trying to add DuckDuckGo without success. I have Google, Bing and Startpage. I click on Find More Search Engines, select and add DuckDuckGo but while it appears as an extension it does not appear in the list of search engines.

About two days ago the cursor started disappearing / flashing when browsing in Firefox. It does not mater where the cursor is placed on the screen either the arrow or the hand will flash when moving. My system is a windows pro 10 system with all updates, last updates for W10 were made a couple of weeks ago, on Firefox whenever it asks to upgrade I do it.

Specifically: 1. If the mouse is stationary there is no cursor, if I move it the cursor flashes. 2. When the system comes up and I launch Firefox all is OK for about 2 – 3 minutes then the flashing begins. 3. If I stop Firefox ie “X” it and restart it the flashing occurs within 0 – 30 seconds. 4. If I restart the PC steps 2 & 3 repeat.

I have two other PC’s Windows Home, and Windows 7, as well as a laptop with Windows Home all with Firefox 101.0.1 all up to date all do not have the above issue. This does not occur with any other programs. I have two monitors, tried Firefox on each makes no difference same problem.

I have tried searching the internet and all I find is about Caret which is off. I uninstalled Firefox and installed it. That made no difference.

Any assistance will be appreciated.

Thank You

Firefox not responding when I open the mobile hotspot on my laptop. I'm not sure if the problem is the program itself or windows or my laptop, but chrome seems to be working fine when I open hotspot, so I thought Firefox has something to do about it?

For more context, I don't have wifi connection in my new apartment, but I do have ethernet cable connection. That's why when I do need wifi for my phone I just open the mobile hotspot in my laptop. When I do, Firefox suddenly crashes/not responding and I have to close it. Same thing happens with discord, but I only lose connection, it doesn't crash. Sure I can use chrome, but all my bookmarks are all in firefox.

This only happened recently, June 2022. I didn't have any problem the month before, I was able to use hotspot while using Firefox at the same time.

Anyone have any idea whats the problem and/or how to fix? Thanks.

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.

Hello,

I'm using Firefox 102.0 (64-bit) on Win 10. When I click on the download icon of email attachments or Whatsapp files, firefox opens the pdf files in a new tab instead of downloading them. All other file formats are downloaded correctly instead. How can I correct this problem, please?

Best regards, Giovanni

My windows 10 pc is set to dark mode, my win 11 pc is set to dark mode, my firefox theme on both pc's is set to dark mode, my phone is on light mode. On my windows firefox which is updated on both devices the top bar will stay dark in dark mode (default firefox theme) but after certain pages it resets itself to light, is this because of my phone being on light mode and themes are syncing over? its extremley annoying and after using the debug: page to try and force darkmode i had to reset firefox due to debug causing issues, now im using an untouched firefox version and it keeps changing from dark mode to light mode!

winget install -e --id Mozilla.Firefox

I am a Windows 11 home 64bit Korean version user. Insider. Version 10.0.22621.105 Firefox latest version. I installed it like this. winget install -e --id Mozilla.Firefox

my installed path. C:\Program Files\WindowsApps\Mozilla.MozillaFirefox_101.0.1.0_x64__(random number letters)\VFS\ProgramFiles\MozillaFirefox Package Root (Where my app runs.)

C:\Users\user\AppData\Roaming\Mozilla\Firefox\Profiles\1234.default-release My symptoms.. there is nothing in that location. Error. So I created a temporary folder. I'm looking for the user profile folder.

Organize my writing. The add-on is working. However. The profile folder is empty. I wonder where it is.

When I right click on an image in Firefox, and choose the "Copy Image" option, it never works. In fact, it hasn't worked in years for me, and that's on numerous PCs, with Windows 7 and Windows 10. I'm doing this so I can paste images into Photoshop. It looks like, instead of copying the image itself, it's just copying the image file, but this means I can't paste it into Photoshop.
