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!!

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.

Windows 10 Pro 21H2, Firefox 119.0.1

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 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?

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.

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,

My extension is greyed out in the Extensions drop down. I have redeployed it in the Mozilla Developer Hub but to no effect. It has been down for a couple of days. What could be the reason behind it and how can I fix it?

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

Tabs always start in mute mode. I can turn it on by pressing speaker logo in the tab. The problem is when I shift to a new tab, the previous tab mutes automatically. For example: I listen to YouTube music and want to check my mail. When I shift focus to the new tab the first mutes it self. Any suggestions please. Sincerely Oscar.

Hello there.

I've notice FF in the past month has stooped maintaining scroll position upon refreshing. It was working perfectly until recently. maintain scroll position upon refreshing is a key feature to my work. Please help!

my browser continues to show symbols instead of words. I troubleshot the font issue and it does not seem to be that. this is on a macbook pro and the browser is updated. I deleted the browser and reinstalled it. which worked for a day but then everything went back to showing symbols. it is intermittent in that sometimes it will show the real words and then a few hours later is will show this.

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.

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.

Hi, I noticed about a week ago that when I would have Firefox windows open on more than 3 of my displays, the newest window, when maximized, would appear with white bars. This does not occur when Windowed or when troubleshoot mode is on. I have attached a photo of the error (suggestions omitted for my own privacy). Bugged window does not respond in this state and cursor does not blink etc. Other Firefox windows work fine. I'm running a custom color scheme, Dark Reader for Firefox, and AdBlock for Firefox. Issue does not occur with Chrome or Edge, which have the same, if not more extensions loaded. Glitch presented itself near the beginning of November.

Please help!

I'll check on this every once in a while, and am willing to run tests.

Wanted to export some bookmarks, and couldn't figure out why (latest Firefox) Bookmarks "Library" was missing relevant buttons/menus. (Screenshots attached.)

After testing, found they actually are there, but have have almost no contrast vs background - that is when "Manage Bookmarks" is called from a Private window. But things look fine when called from a Standard window. (No extensions; same in Safe Mode.)

Can anyone advise?

A simple workaround is to bring a standard window to the front first, but am curious if this is Firefox on all systems? Only FF Linux? Only the particular (default) settings of my Linux Mint 20.3 Cinnamon installation, and display? Not even sure a Bookmark management window is ever meant to assume the theme of the foreground window (here Private browsing's dark).

Thank you.

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?

Hi there, I have configured Firefox to remove cookies after closing it. At the same time, I have added some webs that I usually use as exceptions, allowing to remember cookies in those. However, I have the following question: if I reject all cookies except for the mandatories ones in a website that I added to my "remember list", does that mean that future entrances in that web will be with only essential cookies?

As an example, if I mark https://www.bbc.com/ as cookies, and the first time I enter I reject all non-essential cookies, next times I enter in the bbc will I be navigating with only the cookies I accepted on this first entrance? Or allowing a site automatically accepts all cookies?

Thank you very much on advanced.

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?
