Firefox Support Forum

Hi y'all! I've been trying to get netflix to play recently, and I keep getting the error code F7351. I tried looking it up, and didn't get anything, and also tried to dis- and re- enable DRM content, and that didn't work. Does anyone know what to do? Thanks for any help!!

I moved to Firefox because I have autism and someone told me it would help block the popups and moving content that makes using the web exhausting and difficult. And it does!

The trouble is, it replaces them with something worse – a grey screen that rolls continuously from left to right. It's impossible to focus on text with such intrusive visual distraction, so I have to shut the page down. It seems to occur on so many websites that at the moment it's not worth trying to use the browser.

Half the problem is that I don't know the right term to describe it, which makes troubleshooting a bit complicated. Hopefully someone will recognise it from the description, though – if so, is there any way of stop it moving, please?

Thank you!

when i have any of those 2 flags set to true it opens all links i middle click from firefox-view history all the way to left since firefox-view isn't a tab. I'd rather have it force them all to the right by default instead of it thinking i am not in a tab and have no tabs open

Some websites display poorly on Firefox 119.0 on my Dell computer running Windows 11. Some of the letters of the fonts are too thin and hard to read. They display correctly in Edge.

I have used Inspect Element to see that the font is: font-family: Roboto, Helvetica, Arial, sans-serif;

The problem goes away if I change this to: font-family: Helvetica, Arial, sans-serif;

I do not have the Roboto or Helvetica fonts installed on my computer.

The problem fixes itself if I turn off the setting for "Allow pages to choose their own fonts, instead of your selection above." However, this is not a good solution, because it introduces other issues.

Any help or suggestions would be greatly appreciated.

I have researched this for several hours and tried many of the suggestions online.

1) I have disabled all extensions. 2) I don't have any Themes installed in Firefox. 3) I have tried "Smooth edges of images and text" turned on and off. 4) The problem still occurs when running Firefox in Safe Mode. 5) I don't have a "High Contrast theme" enabled in the OS settings. 6) I am not running uBlock Origin. 7) I have played with Clear Type but the problem was occurring before that. I have tried modifying Firefox's gfx.font_rendering.cleartype_params.gamma to the value of GammaLevel from Windows's registry Computer\HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics\DISPLAY1. 8) I haven't installed any fonts on my computer. 9) I tried setting security.sandbox.content.level = 1.

Hello! Since updating to the last version (119.0.1), Firefox started keeping my open tabs between sessions. This is a behavior I don't want, and the only solution that I found told me to enable "clear history on close", however that is also not ideal, because I don't want to clear my history. The "Open previous windows and tabs" setting is off and my homepage is set to Firefox Default. I don't know where else to look for such a setting, except in the about:config, but even there I'm not sure which one is causing the issue. Any assistance would be appreciated.

Hello,

For the past couple of months I have been experiences tab crashes every day when watching a specific streaming service called wowtv, all my other tabs are fine and work flawlessly. Additionally, after restoring the tab or opening it anew it works again for the next few hours until the next crash occurs. Netflix, disney+ and others work fine as well. So far I have tried reinstalling firefox as well as try other browsers where said issue doesn't occur. I sadly don't have the error message or anything but the video freezes just before crashing, neither closing all tabs 'nor trying an older firefox version fixed it for me.

With regards,

Marcinathi

I am not able to navigate websites per the ADA Accessibility requirements using my FireFox browser. I have tested the same websites in Chrome and the TAB key is working correctly, but in my instance of Firefox it does not. I have a colleague who tested the same website in their Firefox browser and they are not experiencing a problem navigating the website using their keyboard TAB key.

I am on a Mac with most recent FF installed. Colleague was on a PC and tested in FF.

How can I get FF to work correctly on my Mac?

Hi Guys,

I use Firefox personally and for business. I use a lot of very useful extensions and like many users I customize my experience. I have found that the number of extensions I use every day is larger then can be shown on the extension toolbar. I am aware that clicking on the "jigsaw" icon will open up all the extensions, however this is not practical and wastes a lot of time. I would like to substantially reduce the size of the search box and increase the available size for my extensions to be in one click territory on the toolbar, how do I best achieve that please?

Cheers

Your code writers need to write code to handle Facebook. When scrolling through FB the feed constantly jumps ahead 5 or more posts... It's not a FB issue, its a Mozilla issue, in as much it doesn't occur with Google Chrome, or Microsoft Edge... I could use them for FB but then I won't have my Firefox addon's..... Maybe collaborate with their code writers and ask how they addressed this issue...

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

For whatever reason the Picture-in-Picture button keeps not showing up in normal places like Prime, Netflix, Hulu, etc. I can make it come back by going to the Settings turning off the Picture-in-Picture option (Which is always still active) refreshing the settings then going back to Picture-in-Picture and turning it back on and then finally refreshing the video I was trying to use, but this is kind of a lot to have to do every time it happens and it seems to be happening more and more, so I'd like to fix the root cause instead if possible. Any ideas?

Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch

I've created 22 themes and in all of them the drop down menus such as "downloads", "history", "extensions", and "application menu", all became white instead of dark like they used to be. I really don't want to go through the process of fixing and reuploading them, I'd apprecate you looking into this and hopefully fixing it with a simple update. Please fix this problem, thank you!

Ever since about a week ago, my Firefox just started... bugging. Twitch doesn't work, now Netflix doesn't work, basically anything that plays videos (except for YouTube) doesn't seem to be working.

On Twitch, if a person is live and streaming, upon clicking their stream to view it, it's suddenly offline, even if the chat is going and the "this person is live" notification is there. Netflix gives me a f7351 error. Websites with online media (like free movies on putlocker) have multiple streaming services attached and neither of them works.

I've cleared all cookies, cache, data and history.

This is only concerning Firefox, other web browsers work perfectly.

Extensions on my Firefox are as follows: BetterTTV, Dark Mode, DocsAfterDark, Facebook Container, FrankerFaceZ, I don't care about cookies, Instagram Dark Theme, New XKit, TinEye, Tumblr Saviour. No adblocks, no nothing.

My operating system is Windows 10, 64bit, Firefox is updated to 119.0.1.

Any help would be appreciated as this has been the bane of my existence for a while.

To identify myself I had to scan a qr code on a website using my phone. This used to work in firefox but it doesn't anymore. It still works in edge. I'm using firefox 119.0.1 x64 on windows 11 home 22H2. How can I fix this?

Greetings, for some reason lately over the last couple weeks I have noticed that when I open a link to a site that I've had in my bookmarks for years it now opens that link or that page and then within a couple seconds another tab will open for advertisement or possibly even the duplication of the originally called upon link in the previous tab. I would like to stop these additional tabs from opening automatically without my request.

thanks in advance,

I have macbook. When I open a puzzle e.g. sudoku, the puzzle costantly jiggles about (which I have video of). When same puzzle is opened in PC, ipad or Safari this doesn't happen. Why?

Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

when i go to manage bookmarks i can go to views and sort them by last added, how do i make it, so that when i go to the bookmark drop down menu from the top of the screen so also list the bookmarks in order of last added?
