Firefox Support Forum

Hey there, awesomes! I'd like to change my Firefox pdf viewer's background color (both sides of the pdf) to dark, currently it shows light gray (see `background_bg.png`). And here is effect I want it to look like (see screenshot from Chrome `wished_bg.png`). Thanks in advance (:

PS: I don't want to change my theme to dark. It seems I have to change my css, but I dunno which & how.

I have a laser printer set as default on a Windows 10 laptop. In Mozilla, when I select print, that laser printer has the green default check, but Mozilla defaults to Microsoft Print to PDF instead. How can I get Mozilla to accept the default printer without deleting Print to PDF which I do sometimes use but don't want as default? Image attached--it auto-checks PDF but you can see the laser listed above it is the default.

Hello,

I am using Firefox version 92. The screenshot function is not working, both if I right click and request a screenshot from the slideout menu, and if I request a screenshot from the shortcuts/overflow menu (scissors icon). I have attached a screenshot (taken with ‘prntscr” through windows) png of the result that takes place on my screen. The screen will freeze with this image of a large X until I do a refresh of the page. Cntl-Shift-S also does not work. I have tried clearing the cache, running FF in safe mode, refreshing FF, reinstalling FF, and I have ensured that the extensions.screenshots.disabled setting in about:config is set to ‘false’ (also toggled it to ‘true’ and back to ‘false’). I have attached a screenshot of all the settings in about:config that pertain to screenshots.

Thank you for your help.

The possibility of moving icons of those extensions will be a huge improvement.

Please send through to the right department. If those functions still aren't available jet.

Thanks a lot, See the attachment for the example image.

Yesterday when I installed the 96.0 update it has forced my background color into a dark grey and ignores the background color setting. I would like to know if there is a setting, add on or update that can return this to normal. The theme I am using has not been updated in 2 years so I am fairly sure the update has caused this.

I am using Hotdocs portal, which is an in-house document assembly tool. Firefox is the recommended browser, but it is recently handling 2016 docx files incorrectly. When we choose a file on the portal site (internal site), we go through the interview and are presented with a link to "download" the assembled file. When you click that link, a pop-up appears showing the file name as abc.docx but then says it is a Word 97 - 2003 document, even though it is not. The original template is not. If I choose to open the file, it ends up opening and showing as abc.docx.doc If I save the file, instead of opening it, it saves as abc.docx.

If we run this same process in IE/Edge, the file opens as abc.docx as it should. I have uninstalled Firefox and reinstalled. Is there anything that could be causing this? I've tried a bunch of troubleshooting steps and nothing seems to change this outcome.

Thank you.

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

My firefox installed a new update, 89, and now my tabs are missing, except that the active tab is floating down at the center bottom of the screen. i can still navigate with keyboard shortcuts, but i don't know how many i have open, what they are, and personally DO NOT like navigating with shortcuts if i don't have to.

why is it necessary to keep messing with tabs? weren't they just fine below the address bar back in the day? How is ruining the user experience worth whatever was even trying to be done here?

image is how my firefox looks right now

I need an email address or a phone number to contact support. Forms do not have answers for my problem. And the contact and the support pages have no information on how to contact Mozilla which is extremely messed up. Does anyone have this info?

Please help me get rid of the stupid and ugly Tab bar space on newest Firefox. I hate Tabs and now there is a big space above the address bar for Tabs. I have looked everywhere for a way to turn it off like it has been since Tabs came out. I only want new windows if I want a new window.

If I can't turn that huge space gap off is there any way to go back to what I had before the last update without messing everything up? Why did someone decide to make the browser window smaller and waste that space by making the browser bigger....

Sorry if I sound cranky but, I started using Netscape Navigator 1.0 and every version since and this is the worse thing that has ever been done to a browser... Thank you for any help you can give me!

I "upgraded to V90. since then, the URL box is highlighted red/grey stripes. The robot head icon is now in the URL box and it says "Browser is under remote control (reason Dev Tools). I've gone in about:config and set all variables to False, yet they reset themselves to true every time. How do I disable the DevTools. Thanks

Hi guys!

I'm a college student and my university uses Blackboard as a way to access our courses. Unfortunately, my Firefox has been breaking and not loading all of my courses. My university tech support is no help and they told me to contact Blackboard and Blackboard told me to use Google Chrome. I already installed Chrome so I can use it temporarily to do my coursework but I really don't want to use it permanently, I have my computer set up exactly how I like it and I prefer to use Firefox.

I think the problem started around when the September 22nd update for Firefox was automatically installed. Some things I've tried to fix the issue are: 1. Fresh install of Windows using the Razer Blade's recovery to factory default; 2. Update Windows to latest version (except the 2004 feature update, it causes my laptop to black screen on bootup); and 3. Fresh install of Firefox and changing my privacy settings to standard rather than the strict settings I usually use.

I didn't want to install an older version of Firefox because of all the warnings on the webpage, but I'm really not sure what else I can do. Has anyone else had this happen? Any fixes?

System: Windows 10 32-bit laptop

Problem: non-responsive UI on one laptop only. This includes inability to configure local options. nothing works. Menus drop down, but no matter what is selected, the selection does not highlight, menu hides normally but no action is taken by the browser

If I manually type in the url it sits there. no spinning cursor, nothing.

Browser does NOT crash... It simply sits there doing nothing. All other browsers work fine.

What I have done Restart the laptop Double check Firewall permissions Ran a scan before and after installation (0 threats found) Logged in as administrator as well as user account Ran performance monitor nothing alarming noted Uninstall and Reinstall. (Problem still exists)

Widevine will revoke Widevine Content Decryption Module which is earlier than ver 4.10.2209.0. https://www.widevine.com/news

Google has already released new version of CDM. However, the version on Firefox 88.0b7 is still 4.10.1582.2. You can check on the following menu: [Add-ons and Themes]>[Plugin]>[Widevine Content Decryption Module]

My questions are: 1. When is new Widevine CDM coming to Firefox? 1. Can Add-on Manger provide this update to older Firefox?

I have been trying to watch Netflix on Firefox, I made some security changes and at first thought that I may have caused the problem, but now I see that the add-on just fails to install. It just keeps the notification that it is installing. Is there a way to fix this issue?

I am very disappointed with Firefox because of VERY FREQUENT CRASHES! I have the following crash reports:

I have run Firefox in Safe Mode, and I still get the crashes, often on a Checkout page after getting an order together. My software is updated to the latest versions available, and I have kept my security up to date. If we cannot find a fix to stop all this crashing, I'll have to give up on Firefox as being highly unreliable. Since I am totally blind, RELIABILITY IS VERY IMPORTANT TO ME!

The page Give feedback landing page says: ‘Please check back soon’. What does ‘soon’ exactly mean?

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.
