When a tab is opened or moved into a new window (image 2.png), the additional windows will disappear from the Windows taskbar after a few moments (image 3.png) and cannot be accessed via Alt+Tab, the only way to reach that window is via dragging the windows around or with the Firefox View tab.

Imagine this scenario:

  1. I start Firefox and go to a page that requires a login, so I enter my master password.
  2. I leave my computer.
  3. Somebody else accesses my computer. They can go to any site they want, since Firefox 'remembers' my master password.

How can I protect myself from this? I can close Firefox, I can log off my computer or I can use a screen-saver password.

I would prefer a solution within Firefox, something like a button (possibly under Application Menu → Passwords) to force the master password to be re-entered the next time it is required.

Only some videos play without audio, only in Firefox

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works
vp8-vorbis-sintel.webm      Works     Works       Works       Works
avc-aac-nerdist-friends.mp4 Works     MISSING     Works       Works
avc-aac-big-buck-bunny.m4v  Works     MISSING     Works       Works
avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works
audio-sample.m4a    FAILS      Works
ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

The logo in the top left-hand corner of my website's landing page does not display using Firefox but is displayed properly using every other desktop browser. Using Firefox, just my name is displayed in place of the logo. Chrome for Android has the same problem but Firefox for Android displays OK. On my iPad both Chrome and Firefox display properly. What are the reasons for this? Is there some upper limit for the dimensions of the logo (mine is oblong in shape)? Do I have some settings that don't suit certain browsers? My site was built using Wordpress/Elementor/OceanWP. Many thanks in advance for an answer!

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

I use Firefox 134.0.2 (aarch64) as my primary web browser. I only have it open 15 minutes and I am receiving alerts that my RAM memory is being consumed by it. I am using a Mac Mini Pro M2 chip with 32GB of RAM . I have just opened Firefox to discover it is taking 10GB of that RAM. It is the most voracious user. If I have it open longer it gets up to 16GB of memory. I often have 5 or 6 tabs open when I am working. My other browser is Chrome that barely makes it to 1GB

Hello,

I have encountered an issue on some websites where the Japanese text is using the font "Microsoft YaHei" when it should be using "Meiryo." Some examples are on the website bluesky, and bold text on Twitter such as in usernames.

I originally thought it was an issue on my end or in Windows, but when checking other programs and websites such as dengekionline and the non-bold text on Twitter it is using the correct font which I have confirmed via the inspector under the font section. When starting Firefox in safe mode it seems to use the correct font on the previously mentioned websites, so I disabled all my extensions and themes and this did not resolve the issue. I did a Firefox Refresh and this also did not resolve the issue.

I am not familiar with the intricacies on the Firefox about:config to really delve into the exact cause, so I ended up just reverting back to Firefox 134. On Firefox 134 with my same extensions previously the font is now back to Meiryo as it should be which leads me to believe it is something that was changed in Firefox 135. One thing I am considering is that the Japanese text is being recognized as Simplified Chinese by Firefox 135 as Simplified Chinese uses the Microsoft YaHei font as a default.

I have attached some photos that shows my Japanese font settings, and the same post by a user one on Firefox 135 which is using Microsoft YaHei and another on Firefox 134 which is using the correct Meiryo. I have also tried disabling the "Allow pages to choose their own fonts, instead of your selections above" and then restarting on 135, but this did not resolve the issue. Thank you for your consideration.

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

For some time now I have not been able to access any website secured with Captcha verification. My browser doesn't recognize that I'm a human and keeps going back to square one. Importantly: this problem does not occur in other browsers. However, I would prefer to stay with Mozilla, so it will be nice if something can be done with it. I didn't change any settings, I didn't change hardware, I didn't reinstall Mozilla, so that's not the problem. I've looked through my security settings and don't see anything that would help in this case. Especially since these are websites that I had previously accessed and logged in without any problems.
