Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

Things like, "set firefox as your default browser" and "open firefox when you start your computer?".

I don't want pop-ups from ANYBODY, but especially not from the browser. It defeats the whole purpose of blocking pop-ups if the browser itself is interrupting me with garbage I dont need.

How do I turn these off? There don't appear to be any settings, and every google search brings up disabling pop-ups for every other site.

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

Firefox 146.0.1 crashes every time upon launch (basically fails to launch), even in troubleshooting mode, with exception code 0xc0000005. Prior to today, it was working fine. Windows does not show any updates made over the last couple of days. I am on Windows 11 25H2, and I'm current with updates. Chrome works. Edge works. I logged on to the same computer as a different user (different profile folder in the user AppData folder) and Firefox still does not work. I tried to refresh Firefox and that did not resolve the issue. I tried to uninstall and reinstall Firefox and that did not resolve the issue. I tried to run DISM and SCANNOW and that did not resolve the issue. No issues are detected with a virus scan. I am stumped - please help!

Images have not been displaying properly. Or when they display properly, the images may go blank when scrolling past them or hovering the cursor over them. This is specifically troublesome with buttons to click on to confirm "yes" or "no", "next" or "start" where the text within those buttons is not visible.

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.

It's not clear to me from the general help instructions how to get my passwords and bookmarks from my old computer to my new one. All the files from my old computer were transferred into one big folder and placed on the Desktop of my new computer. I don't know how to find the right file in the backup and where I need to copy it to on my new computer. I know a while ago I had to recover my passwords, but I forget the steps I went through and it was all on the same computer so slightly different situation although as I recall it was not all that difficult. Any help would be greatly appreciated.

Hello, I've been using Firefox for several years because of all browsers it's the only one (I know of) that has a setting whether to open links in new tab or in new window. I want them opening in tabs. This has been quite alright until last week when I was suddenly shown a message that I was using an old Firefox version and was forced to create a new profile. I did that but ever since then links keep opening in new windows - even though I have found the relevant setting and ticked the box "Open links in tabs instead of new windows". With or without the box ticked, the only way to open links in new tabs is to simultaneously hold Cttrl and click on the link. I've tried all variations of this box and the next two, but no luck. This is really important for me. What am I doing wrong? Thanks!

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.
