Firefox Support Forum

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

I already found many users asking the same, but they didn't get a reply.... at least I didn't see any.

I want to protect my password memory with a master password - fine. But in 99% of my time, I don't need to enter login data. Even worse, if FF starts on an "invisible" monitor, I cannot move the window.

Is there a way to have FF prompt only for the password if I attempt to log into a site ? ... it already does that when I cancel the start-up prompt.... so is there an "auto cancel at startup ?"

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

FF loads so slowly and blocks so many sites that I had to disable enhanced tracking to get to mozilla.org. It can take up to 30 seconds for a site to load if I don't disable enhanced tracking, and even then, some won't load and will time out. I have 7 pinned items that load when FF opens, and it can take up to 5 minutes for all of those to load. Even on some sites where I have enhanced tracking turned off, I have to close the initial block page to get the site to load. Sometimes I have to stop the download and refresh to get the page to load. It is blocking sites that I've used for years with no problems.

What I have done: Troubleshoot mode - loaded a bit faster, but still had problems with some bookmarked pages I've used for years with no problems. It seems to hate all Google Pages, especially Google News Turned off Deceptive Content and Dangerous Software protection Turned off HTTPS only mode Turned off Block Popup Windows

Since the update to version 125 Firefox on Windows 11 (all updates installed), when I open a new tab and start typing to the address bar WHILE the VPN to the office is active, Firefox locks up and can not be used anymore.

In taskmanager, there is no spike in memory or cpu usage visible. All I can do at this point is to kill Firefox via taskmanager.

I can enter anything in the address bar of an already open tab with an other website open, I can open new tab from the bookmarks, but I can not open a new tab and start typing in the address bar while the VPN is active.

Once I disable the VPN to the office, everything goes back to normal.

I never had this issue on a previous version of Firefox.

Any ideas whats causing this?

I'd like to organize bookmarks alphabetically, with folders listed first, at the top of the list, followed by bookmarks not saved to folders. How do I do this? An example: Folder A Folder B Folder C Acme Co inc Beta Corp, C corp ...etc

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

hi, my discourse account is suspended but i wonder why? i try to reach discourse staff but i cant. because email address not working in this page: https://discourse.mozilla.org/about

my profile is: https://discourse.mozilla.org/u/tugrul/summary

please unsuspend my account. thanks.

when I entered this string - chrome://pippki/content/exceptionDialog.xul - I got a 'file not found' message. Is there another way to access that? I am trying to get to https//mlb.tickets.com and get this message: The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

I have at least some computer knowledge but not enough to understand the link on the crash report that says what this report means. Is there a cliff notes version of why my firefox keeps crashing. I have link to the page so I am not sure what info is needed to help me. I can give screenshots or link info. I'm not sure if it's safe to post everything on report or what is necessary.

When I pause a video (any site) and go to another tab / stay on the site, after a seemingly random amount of time the video starts playing again.

I'm using latest Firefox on Ubuntu 22.04 (snap).

I've tried (didn't work):

• Disabling media hardware controls through about:config
• Disabling autoplay through about:config
