I am experiencing many times that Firefox prints garbage, not what's on the screen. To get around the problem I switch to Safari.

Is anyone aware of this or I am the only one experiencing it? Is this a known bug?

One example:

Prints little circles...

If I switch to Safari, I get on paper what I see on the screen.

I updated my Firefox today and now videos do not play.

I had this problem back in April after an update and I spent weeks troubleshooting it. Eventually I got it to work after trying all of the following (then, and again now):

Things I've Tried: 1.) Clearing data (cache and cookies) 2.) Turning off "Strict Mode" 3.) Running CCleaner 4.) Disabling/enabling HW acceleration 5.) Checking that the DRM box is checked (and trying it without it checked) 6.) Refreshing Firefox 7.) Uninstalling/Reinstalling 8.) Updating my Windows install 9.) Updating drivers 10.) Disabling all Firefox extensions 11.) Running without extensions 12.) Running in Firefox Troubleshooting Mode 13.) Running Windows in Safe Mode with Networking 14.) Running a fresh install of Firefox without signing in after deleting all traces of Firefox from my PC (including Program Data folders, registry entries, etc.)

What finally worked back in April was to dive into "about:config" and change "media.rdd-processenable" to "false".

That fix does not work this time around.

In the meantime I've been using Brave and having no issues. I've tried video playback in Chrome, Opera, and Edge on this computer with no issues. This playback problem is exclusive to Firefox.

Video playback still works just fine on my 4 home PCs running Windows 10 and Pop_OS (3 self-built, one Asus laptop) using this same build of Firefox.

Other/Rant: I suspect this is a Firefox/Windows 11 problem. Most likely this is not something I can fix myself, but it's incredibly frustrating since I'm buried deep in the Mozilla ecosystem and use it for work. I'd prefer not to have to swap between browsers just so I can watch videos; too many windows open on this tiny work laptop isn't fun to juggle. Basic video playback is the #1 thing I use my web browser for at both work and home so it'd be nice if this irritating, months-long, unacceptable issue were resolved. A modern browser that has video playback issues? What good is it then? What's most irritating is that it seems I'm the one of a very small number of users with this issue, since I see very little posted about it online.

I've been a Firefox user primarily for almost half a decade now - moved over from Chrome for privacy issues. Never had a problem until 4/22 of this year and considering it's still an issue 3 months later... it has me re-evaluating the reliability and my commitment to an otherwise amazing browser.

Using Firefox v91.11 I can't print a selection from a web page as the 'Print Selection Only' option is grayed out. This has never been an issue for me in earlier versions but appears to have been a problem with Firefox going back many years. This is the second time I have asked for help in solving this so I would really appreciate a response as I can't find a solution anywhere.

Note that the issue is only a problem when trying to print from a web page using Firefox v91.11. Safari doesn't even offer this option but the option is there and works in Chrome.

Thank you

I don't like the new printer dialog box Firefox came up with. It is too basic. 9 times out of 10 I have to click over to the System Dialog Box. Is there any way I can permanently switch to System Dialog Box? I am running Windows 11/64

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

Whenever I type something in the URL bar that starts with the word "amazon," instead of getting a Google search for what I typed, I get redirected to Amazon.com with whatever I typed as a product search. For example, if I type "amazon sucks" in Firefox's URL bar, instead of getting a Google search for the phrase "amazon sucks," I get an Amazon page with the word "sucks" pre-filled in Amazon's product search (and a screen full of socks).

I don't have a search keyword for "amazon" in my Firefox settings. As far as I can tell, no other magic word does the same thing. (For example, if I type "yahoo sucks" or "walmart sucks," I get the desired Google searches. I don't get redirected to a Yahoo or Walmart page.

How do I turn this behavior off?

Firefox 102.0.1 (64bit), Linux, Sway (Wayland), MOZ_DBUS_REMOTE=1, MOZ_ENALBE_WAYLAND=1 When I hover over a menu item, the hint shows up and the menu disappears visually, it is still there, as I can interact with it (mouse click or enter).

I am in the process of moving all of our passwords into 1Password. However, I discovered that my wife has her Firefox set to auto login, but can't remember her user name and password. So, although she can use it, she can't change update the password. The fact that on setup, auto login is the default makes this doubly frustrating. So, is there any way to get to the password?

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

After switching to Firefox version 123, I encountered an error on our website: '1,000,000.00 is not a valid number.' It seems to be a form validation error, but it worked fine with previous versions of Firefox. The application is built using GWT (Google Web Toolkit). Any help would be appreciated. Thanks.

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

This command doesn't work, and I've seen others with the same issue and no one ever gave a response on how to fix it.

I'm assuming the same thing will happen here, but I just started using Fire Fox and really hope someone can give some resolve.

I tried running with no extensions too, it still didn't work.

Microsoft Edge Control + Shift + N works

Chrome Shift + N works

I tried this solution "Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem. " It didn't work.

Please could someone help me. Firefox has been my favorite go to browser, but now I am forced to look for alternatives.

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

Unable to download jpg file complete. Get error message and image down will have .part after filename.jpg. DeepDreamGenerator.com site from user 'file manager' view. Can download ok if I right click image to show in new tab. Cannot find adblocker to disable which was DDG Team suggested was happening. I can download from file view in MS browser. Problem started after latest update.

In Firefox-Mac, I used to be able to save webpages as PDFs without page breaks as one long page (sometimes 120 inches), depending on the page. The newer version it doesn't work. Now I have to use Safari (!) for this. This is a useful feature for proofreading, where page breaks often break up or omit entire sentences.

When I try to log in to websites, three different usernames are prompted. One is my correct Gmail address, one is my correct mobile phone number, and the third is my correct Gmail address with 'joseph' appended in the case of Firefox, but 'busy' in the case of Chrome. How can I delete that corrupted prompt from Firefox ?

I've been with yellow folders for several years. In the version that I have now, version 111, no longer works. I was put at userchrome.css the following: @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); .bookmark-item[container], treechildren::-moz-tree-image(container) { fill: gold !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksToolbar) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksMenu) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_UnfiledBookmarks) { fill: black !important; } treechildren::-moz-tree-image(container, livemark) { fill: orange !important; } .bookmark-item[container][query], treechildren::-moz-tree-image(container, query) { fill: dimgray !important; }

I do not know because it doesn't work now. Maybe version 111 no longer admits it? Do you know how to put the yellow folders?

I have to buy a new iMac, which now comes with Sonoma. Is there a version of Firefox that works without major issues on an iMac with Sonoma or is it better to wait? Thanks.
