Hello to everybody, My question: Opening local .mdb files (MS Access database) does no longer work in Firefox 120, but was ok in previous releases. The only choice is to save the file rather than onening it with MS access. Under Firefox settings/applications the file type .mdb does not appear. If I answer the question "What should Firefox do with other files?" with "Ask whether to open or save files" it has no effect at all. I expect to find an entry for .mdb files where to choose "always ask" as was the case earlier. Please help!

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

All images, webm, gif etc. are loading, seemingly, exactly 20% upscaled compared to the real resolution of the media. I'm using a 4k TV (S95B), but I have desktop scaling at 100%, and browser scaling at 100%. I don't believe it's a GPU or OS system wide type setting because windows photo viewer gets pictures right. I'm using ShareX to measure the pixels of pictures. I can even load a local picture in a tab, and it will be upscaled beyond its native resolution. I have no idea why. I've tried a bunch of things, like setting layout.css.devPixelsPerPx to 1.0, which did nothing. I've reset Firefox to no avail, and I have noticed that Chrome is doing the same thing, which would usually indicate it could be the OS or GPU driver, but again, other apps load images perfectly normally. Do apps have categories on Windows now, where something like a "browser" can be told to treat media files differently than other media handling categories? I'm really lost at this point, nothing seems to work.

Hello,

we have a BigBlueButton Server setup for our company. Until recently we used a TURN-Server to tunnel the UDP connections thrugh the firewall.

Due to performance issues we wanted to try and let the clients connect directly to the udp ports 16000 - 32000

In Chrome this works as expected.

In Firefox however when we set "media.peerconnection.turn.disable" to "true" FF does not find any WebRTC candidates. We checked the logs and it says there:

"relay only option is set without any TURN server configured" "relay/proxy only option results in ICE TCP being disabled"

But thats NOT true! The option "media.peerconnection.ice.relay_only" is definetly set to "false"

Tested on FF 115.5.0 ESR and 120.0.1

Does anyone have an idea whats happening here? Why doesnt FF even try to make a direct connection?

UPDATE: I just ran a test on our dev system. If we configure BBB so that it does not offer any TURN-servers, FF uses a direct connection. Sadly that is not possible, since we need the TURN server for external connections. When there are TURN-Candidates but TURN is disabled via FF config no connection is established at all. This definetly semms like a bug in FF, since the browser should still be able to simply try and connect directly.

Thank you for you support

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

Extract media links is displayed in the firefox right context menu I want to hide it from the right context menu. What should I do. Can't it be hidden? Firefox Version 120.0.1 64bit Windows11 Home 23H2

Steps I've taken to try to fix the issue. 1. I've cleared all cookies/cache/history 2. I verified that network.dns.disablePrefetch is set to True 3. I started Firefox in safe mode 4. I've made sure Firefox is up to date 5. I've tried modifying security.tls.enable_0rtt_data to both True and False and reset firefox after each attempt. 6. I am able to get to google using any other browser but Firefox is having issues. 7. I am able to ping google and google dns from cmd. 8. I've tried clearing local dns cache and trying again but no luck. 9. I've uninstalled Firefox and reinstalled, still no luck. I cannot use google.com or use services like Crunchyroll that use google to login.

I've been trying to sign in to pinterest, duolingo, etc using the 'sign in with google' option since my account was saved there. Whenever I click it, a sign in window opens up as usual, but it only ever shows a blank screen. No matter how long I wait, nothing shows up. I tried clearing cache, and it still didn't work. It worked before, but recently since the past 2 weeks, it became like this and I don't know how to fix it.

I have some extensions on my account so I'll list them out just in case one of them is the one making this problem: -Search by Image -Firefox Relay -uBlock Origin -DuckDuckGo Privacy Essentials -TWP - Translate Between Pages -Ecosia

(Below is a screenshot showing what I mean by the sign in window being a blank screen.)

I've spent many hours trying to fix this problem. When I click on a document that I want to view, it is downloading to my computer. I have the latest version of firefox on a windows 11 pc. Please assist.

learning windows 10 - closed a window retrieved from the taskbar - can i get it back with its 49 tabs? i can get an active window showing the recent files i was working with, and i can open ONE of the tabs ("one document") - went too fast i guess. thanks for any response. hope i did the "share data" for you properly.

Firefox on my mac has recently started displaying strange text in any windows where the browser itself chooses the font. I verified that the font settings are default, and the issue persists. Screenshots attached, any ideas?

Only my mac has this issue, my iPhone, as well as two Windows PCs all on the same account do not present with this.

Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

Hi,

Someone is trying to visit our website but keeps getting a 520 error response.

It appears that their user agent is being blocked at some point but I don't know why or where (I have tested the user agent in browser tools and get the same response). Yet, using it to visit other websites works fine, likewise if they test using another user agent they can access the site.

We use Cloudflare but I don't think the issue is their end as we have sites hosted elsewhere which can be accessed through the CDN with the same user agent.

Checking the server logs shows no sign of the visitor's IP address accessing the site.

The user agent is: Mozilla/5.0 (Windows NT 6.1; rv:33.0) Gecko/20100101 Firefox/33.0

Just wondering if anyone can suggest how I might be able to narrow down where to find the issue or what I should be looking for? 33 seems like quite an old version, could it be the server doesn't accept visits from an older version?

Many thanks

For over a week now I am receiving a popup from 'The Spruce' with the popup header being Mozilla Firefox (see Spruce.jpg). The popup has a facility to disable notifications from www.thespruce.com and I have selected this many times yet the popups keep coming several times a day. (see Spruce2.jpg). I have also visited the Spruce website and there is no unsubscribe link. I didn't subscribe in the first place and had never heard of The Spruce before this. Why is Firefox facilitating this spam that won't be disabled?

So for folks who hand wrote thousands of lines of Actionscript code for Adobe Flash, it is incredibly upsetting and frustrating that a witch hunt went after Flash which we believe was part of a tactic by google to ensure its ads cannot as easily be blocked. Specifically google used all this "modern web" nonsense to become the monopolistic browser in place of internet explorer and to use that "power" explicitly to bend the future web to their will.

This is so upsetting, there are not words to describe it. And the fact that the "answer" is that folks who spent years and thousands of lines of code for Flash, now "simply need to completely re code everything from scratch in a new language" is offensive beyond recognition.

Please consider removing this "standard" response language or at least acknowledge the awful burden that was placed on folks by the decision to join the rest to remove the most popular web technology that helped build the internet, because google must serve everyone ads. It is just gross.

Honestly, we thought Firefox would defy the witch hunt and keep flash working to differentiate and look after the poor developers who suffered from this terrible, terrible action.

p.s. on the day Flash was officially killed off, chrome had more active "severe" security vulnerabilities than Flash. Thus, chrome is objectively less secure than Flash. I wonder how much google spent on paying news companies to post stuff about how "insecure" flash is and the stupid "modern web." I wonder if said "news" companies checked the claims, or just took the payment and posted their "sponsored content."

Hello,

I recently purchased a VPN for my laptop. I bought a designated IP address set to Toronto, Canada. However, Firefox shows my location in Japan.

In my communications with VPN server they believe since whatsmyipaddress shows me where my VPN says it should, but FF shows me in Japan, the problem may be a leak at your end. When I created this account today and set my country to Canada (as suggested by PIA), closed everything and rebooted my computer I had hoped to see Canada (en) when I began a search. However, it still shows Japan.

I value my privacy on all devices and turning off location is the first thing I do. I'm now wondering if FF is getting this location from Windows.

Any assistance is most appreciated. Thank you,

I have Windows 10 Pro 22H2 19045.3803. I am running two monitors. When I have many Firefox browsers open on both screens, reboot and restore previous session, the browsers all open in what ever monitor the initial browser was opened on. I haven't tried it with other browsers. All other applications open in whichever monitor they were in on reboot.
