We are using a website designed for Firefox, and when we use the "print" function within the website tool bar, on one of our PCs, it always defaults to a print preview which states "Printing from Win32 Application - Print". We have "print.always_print_silent" set to true, on this and all of the other PCs using the website, but only this PC has the issue. We can't figure out what is making it pop up the print preview.

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

This randomly happened over the past few months but last couple days it's bad. The Google Sheets cells I have open on Firefox turn black. You can scroll and they will come back but just briefly and back to black. Very annoying as these are shared sheets for my business with other employees. It's not happening in Vivaldi Browser or Edge. I hate Chrome so not even trying it there but guessing it's fine. Seems to just be Firefox all of a sudden. See pic. Help please as I have no clue what's causing this.

Hi,

Why is it so much updates all the time with Mozilla Firefox NIGHTLY Browser for the 127.0a1 version that was released 15th of April 2024? I don't even see the benefits of the updates or any information and what the content is in them. by clicking on "What new" doesn't show anything other than this from 15th of April.

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPH but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

Currently, when I try and open downloaded .txt files and .log files (that is, when I click on them directly from the download pop-up that appears at the top-right of the browser), Firefox inexplicably opens Aegisub on my machine as the app to use. This is in contrast to when I open it directly from within my file browser, where it opens the Kate text editor, as suggested by the default app option in the permissions of the filetype.

How do I change the apps Firefox uses to open downloaded files? I've tried going into my settings and looking at applications, but .txt and .log don't appear, so I'm not quite sure what to do.

I'm on Kubuntu 22.04.3 LTS, using the Firefox deb package.

All of a sudden, Firefox (125.0.3), running on Windows 11, is not delivering any sound at all on websites which have music or people speaking. The TOR browser does deliver the sound on those same websites.

Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

I have made Firefox my default browser, and set Google as my default search engine.

I'd like to keep it that way, BUT ...

Every morning when I come to work and open my browser and begin to search .. Yahoo comes up .. or Bing ???? I delete them, and again set Google as the default ... BUT FIREFOX CONTINUES TO REVERT TO YAHOO, or BING SEARCH RESULTS  ?!?!?!?!?!?

Even when I deliberately open Google and search in Google .. the results appear and then suddenly, a new window pops up with Yahoo results, covering up the Google results????

How can I make Firefox respond to the default search setting I choose????

This is intolerable. If I can't get ride of Yahoo and Bing and all these other inferior search engines, then I'm going to go back to using Chrome.

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

Hi All,

I would like to change the color of the two highlighted URLs in the address bar's drop down list to what they were in FF 88 - the one that is currently selected with the cursor keys, and the one the mouse pointer is over.

The first screenshot below is of the highlight colors in FF 115/125. You can see two different shades of gray, the darker gray being the URL selected with the cursor keys, the lighter gray being the one the mouse pointer is over.

The second image shows the colors from FF 88, the URL selected with cursor keys in blue, and a dark gray for the one the mouse pointer is over.

Any help in modifying these colors, and the radius of the selection is greatly appreciated!

Hi folks,

I've searched, but I haven't found anything to help with this particular situation ...

I love Firefox/Mozilla Sync and I use it a lot, but I've recently had a desire/need to set up a scenario that some may think perculiar - let me set the scene ...

• Work PC running Firefox - 1 profile
• Work VDI running Firefox - 1 profile
• Work laptop running Firefox - 2 profiles (work & personal)

Mainly for the sake of sending tabs to the appropriate Firefox profile on the laptop, I want/need to be able to config things in Sync to treat those 2 profiles as being different entities. Currently, it appears that all profiles on a device (or within the same user profile on a Windows computer) are treated as the same entity by Sync.

Any ideas on how to achieve what if trying to do? Is it possible with Firefox/Mozilla Sync?

Thanks for your time.

BTW., for clarity, if it matters, the devices listed above are all Windows. FWIW., I also use FF on Android and Linux ... and MacOS.
