Firefox Community Forum

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.

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

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.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.

I get this multiple times per week and then have to delete all amazon.com cookies and relogin to everything.

Hoping someone has a solution as I would prefer to continue to use Firefox but this is getting very annoying.

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.

I've been having a problem with FF for the last two weeks. At times downloads accessing web sites are slow or even get hung up. Usually reloading or refreshing the page fixes the problem. I tried a FF safe boot and things seemed to work better. I have had the same four extensions for quite awhile. Are there any reports of UBO causing issues?

i have been using firefox for quite some time. but as of late when i open a reels video on f/b sound works fine just no video. i have deleted ff and re loaded the latest ver. it will work on microsoft edge any help appreciate

https://shop.sportsbasement.com displayed and work 3-4 days ago. Now blank. https://us.muc-off.com/ blank https://www.asp-usa.com/ blank https://byrna.com/ blank

I have cleared cashe, history, Turn VPN off, Turn adblocker off, these were all on when it worked. Now nothing

I've had FF for years and never had a problem. In the last week, when i read an email with a link (and other links), it says Hmm. We’re having trouble finding that site.

We can’t connect to the server at clicks.aweber.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

https://clicks.aweber.com/y/ct/?l=jKs7l1&m=h.2234KUji5Kx0L&b=o5yQLV_ae7nzu_vG4KA6iQ

As far as I know, I have not changed anything in settings. I'm looking for some resolution on how to fix this. Thanks.

When I click on a txt file on a Facebook page Firefox no longer opens the file - it opens another instance of the webpage in a new window. The same link opens as a text file in Chrome.

I can't get the lastpass extension to load in the browser. It worked fine up until I upgraded firefox this morning. Other extensions are loaded fine ( privacy badger, clear urls). I removed the extension and re-added it but no success. Any ideas. Hate to go back to Chrome..

I was on Talbots.com and tried to go to the shopping cart and then to checkout. I keep getting this message:

"Please make sure that Javascript and cookies are enabled on your browser and that you are not blocking them from loading."

I do not know how to make sure that I am not blocking them from loading. Please help!

When I click on a website the page is completely blank. Not loading, no error message, just white. It happens on a lot of web pages but not all of them. Youtube is fine but a lot of others dont. there doesnt seem to be any pattern to the type of websites that dont work. sometimes the website will work the first time but if I close the tab and then click on the link again it wont work. It seems like the code of the website has somehow been deleted? (see photos). Ive tried disabling literally every extension I have and reloading the page but nothing happens.

I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

I have tried everything recommended to try and log into the ATT email website. What is weird is that the email is coming into Thunderbird just fine and I can log in using the Edge browser. I only log in to the ATT site every so often in order to mark emails as spam and occasionally to look in the spam folder for a missing email. I have deleted the cookies for this website and the history as recommended. I don't want to delete all my cookies as it is a real pain to have to log back in to all the sites I regularly use. I saw on a Microsoft site that this is a documented problem and sometimes changing one's password helps but I can't find a way to change my password. I'm no longer an ATT customer (after getting a better internet provider that ATT DSL!) but I still use that email address. I am baffled. Appreciate your help.

I've been using Firefox for the various iterations of Windows for many years and it's gone smoothly. Now, when I play a YouTube or Instagram video in Windows 11, the video often becomes just an image of pixelated multicolored squares. The sound continues to play normally. On YouTube, the video continues to play. On Instagram the video tends to freeze. I've attached a screenshot from an Instagram video.

I checked my external monitor and it's definitely the laptop, which is less than a year old. This only happens with videos and other browsing works as usual. I have no issue using Chrome, so it seems to be a Firefox thing. I tried clearing the cache and history. When that didn't work, I uninstalled Firefox completely and reinstalled it. Same issue. I've attached a screenshot from an Instagram video. Thanks for any advice you can offer.

Yesterday I could not access my account to view recent statements. It would not accept username , which bank insured was correct(as it is my account #). Anything I entered flashed an ALERT message that info was incorrect.
