Firefox Support Forum

So I have a video playing on firefox, but the moment it drops from the foreground, it immediately pauses the video (the actual video playback). The audio continues, but the video stops until it is back in the foreground, at which point the video continues where it ought to. I have tried disabling the unload tabs in the config menu as well as disable the foreground pausing or whatever its called, as recommended by previous posts. I used to not have this issue at all, so I'm not sure what changed. Please help! Thank you.

I was having trouble with Firefox freezing and needed to close it with Task Manager and reopen it whenever this happened. On one of these restarts, only a few of my windows opened up with the new session. All of the other open windows vanished. They're not in my history or my recently closed windows at all. There are three specific windows of the lost windows that had data I was actively using and don't want to lose. The URLs would be enough. I was also using the other windows, but I can re-find that information easily enough.

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

Up until Firefox 116, Reopen Closed Tab (Ctrl+Shift+T) would reopen closed tabs, and Reopen Closed Window (Ctrl+Shift+N) would reopen closed windows. There was a clear bifurcation, so I could freely close windows and not worry about it polluting my tab history in another window.

The latest change has thrown out that advantage, and now Reopen Closed Tab reopens both tabs and windows, while Reopen Closed Window still just reopens windows. This makes the later essentially useless and the former much more difficult to use for me.

I assume this was done to just continue copying Chrome in all respects since that's how it handles it, but the changelog just vaguely states, "This change is in anticipation of upcoming changes to recently closed tabs."

Does anyone know if there's a setting to separate the two functions again?

Firstly, I have looked around on here for a bit and have not found anything.

I uninstalled Firefox because it was needing to update for a very long time, giving me a pop up every time I would open the browser, but if I clicked on the update button, it would just take me to a page on Mozzila that showed nothing regarding updates - if you scrolled down you'd get a normal download button for the entire browser which I already had. On settings, it would tell me my browser is up to date. Websites would give me pop ups saying I need to update my browser.

So I uninstalled it. And now I can't reinstall it.

I have Windows 10. On the Microsoft store, I have Firefox, but the "install" button does nothing. This is typical for the Microsoft store for me. On the Mozilla website, I can't get past the initial download page, I click download and it takes me to an error that says "this site cannot be reached" (so, please, do not link me to https://www.mozilla.org/en-US/firefox/all/#product-desktop-release or https://www.mozilla.org/en-US/firefox/new/ both take me to the same error page). I have already turned off Windows Defender, and turned off my ad block.

All of the info I have found assumes I already have the installation files, but I cannot access those because of getting the error I described above. No idea where to go from here.

I've recently switched back to Firefox from Edge and have run into a frustrating issue.

When I try to print documents from Firefox, the "Color Mode" in the print settings is grayed out so I can't select B&W.

This same problem exists both on my MacOS laptop + my Windows 11 desktop. Additionally, they are connected to different printers on different networks. It also occurs whether I'm trying to print a PDF or anything else in Firefox.

Based on this, it appears Firefox is the culprit here.

Any ideas on how to fix this?

Firefox Version: 108.0

The Certificate Manager dialog (Settings -> Privacy & Security -> View Certificates...) has gotten to the point where it is extremely wide (greater than one screen width! Luckily I have 2 monitors so I can expand the FF window wide enough to get to the grab handle in the lower-right corner of the dialog). If I grab that resize handle in the lower-right corner of the dialog and attempt to shrink it, it will not get any smaller - I can only make it bigger. (What has caused this problem is I have attempted to reduce column sizes in the dialog, but the columns have only gotten wider!) I see no controls to be able to reduce the dialog size to a reasonable width. Am I stuck with this forever now?

Twitter not working properly on Firefox (Volume on videos can't be changed, hovering over buttons doesn't do anything and font looks a bit off, could be just Firefox font or something) works on chrome and other browsers.

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

I've set custom fonts through Settings > Fonts > Advanced, but the fonts I have specified are not being used on any websites even if I uncheck the box that says "Allow pages to choose their own fonts, instead of your selections above". For example, I've set the default sans serif to Source Sans 3, but websites use Arial regardless of the settings. The only custom font I've gotten to work is Segoe UI (the UI font on Windows); all other just fall back to Arial. The problem persists even if I disable all extensions/add-ons. I'm also experiencing the problem for non-Latin scripts; I've tried to set the default Bengali font to Noto Sans Bengali, but websites are using Vrinda instead.

I'm running Firefox version 120.0 on Windows 11, any help is greatly appreciated!

Greetings from North-East of France, since a few weeks ago I'm seeing a (sort of) pop-up window suggesting to login with a Google account (see the screenshot attached). I've done some internet search to find out how to get rid of it, but the only suggestion I get is to modify an option in a Google account. However, I do not have a Google account! How to get rid of this disturbing pop-up? I already use Adblock Plus and uBlock Origin, yet Google passes through them! Thank you in advance for any help you may provide.

Version 120 (PC) continuously crashes and asks me to refresh and nothing happens (including after rebooting) so I had no choice to uninstall. I normally trust your updates but I'm really regretting this one. Can you help me not switch over to chrome? Maybe you're already aware of this bug and will have it fixed soon.

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at allI am at a bit of a loss, any ideas?

I uninstalled Firefox which I had used for years because when I tried to open it it said the file was corrupted and unreadable. I installed firefox today but it didn't import my bookmarks. I use windows 10

I am running Firefox v 120.0 (64bit) on Windows 10 Pro version 22H2 OS build 19045.3570 and today Firefox has stopped playing the video track on youtube videos or any video that is embedded in a page. Audio works but the screen just shows a blank field of green. The progress bar will show frames from the video. IF I run Firefox in trouble shooting mode the videos play as normal with video and audio tracks.

I have already refreshed fire fox and uninstalled and reinstalled it but the video track is still a blank field of green in both full screen and small screen modes.

Anyone have any ideas on what configuration setting may be causing this? Thanks in advance, Brocky

I get this message when trying to access this site: "We can’t connect to the server at www2.optumrx.com"

I can then go to another browser, like Edge and I have no problem accessing the site. I am using a Windows 11 Lenovo computer running Firefox 120. This problem just started to occur.

I can sign into YouTube ok, and the pictures of the video's are ok, but whatever I try to watch I get a green screen and just the video sound? It started happening yesterday. I am getting fed up with YouTube and the issues it has with Firefox. I'm having to use Microsoft Edge to watch videos. I've done the 3 resets it says on the support page, but still have the issue. Many thanks for getting back to me.

It is ABSURD https://bigthink.com/neuropsych/tab-overload/

Why browsers UI didn't change from 1999, when we know it causes tab overload, brain has to constantly filter everything it sees and how we engage with information is cruical in this age. All we get after 24 years are 4 categories to group tabs. I had even 3000 tabs peaking, average 1000+ reading philosophy. Einstein said: "human stupidity is infinite"...

Bookmarks are atrocious, you cannot even scroll panel with mouse holding bar, cannot cltr+f for existing folders, bookmark manager doesn't find existing folders, it sorts folders with bookmarks together contained under a folder... Doesn't have even tags, with thousands of bookmarks and folders, it would take 10 minutes to find fitting folder... I didn't also find any good 3rd party solutions really...

There are tab manager addons, but if you have again a lot of different tabs, it won't help you, it is useful for short-term workloads, but then you have nothing to store things in more permanent way. Also making notes all the time with reading would cost too energy especially if you need to research many things together... There is prototype of AI that saves all things based how you hover cursor over text etc. It would be great if it supported AI tracking and then highlights important info and makes notes, it is not publicly available yet in some solution...

Note taking programs suffer from same issues, missing core features, chat with AI is still very rudimentary and won't help you bring some small notes or piece of info you read 2 years ago, or something specific on-demand... When note taking program cannot even collapse notebooks on main view and you have seeing like 100ths different entries, or doesn't show available tags and selecte multiple of them quickly together under each notebook...

bottom line: there is no tab management really and all addons are really basic and doesn't support long-term intelligent storage for a lots of tabs so you find what you look for later, bookmarks are unuseable after certain amount (again no good third party solutions i saw...). Note taking programs all suffer from same issues, missing core features, again it is impossible to navigate any else way except using tags, but then if you have many then what, you cannot use tags to find thing nested under 20 other things, some specific bit of info, it will still be vehement to sort, if you cannot use multiple things together like jump to notebook and then see all tags what are there available, which would work better, you cannot remember all tags in each notebook you have... All solutions that exist missing core features and are overly simplistic and vehement... This gave me executive dysfunctions...

And if i give feedback to devs of absolutely logical core things, or what could be better and is missing and what stems from purpose and function and is self-evident: they tell me i am brilliant, it is ABSURD... Don't know what to say... 2023 there is still not way to efficiently make notes, capture knowledge... Even my former 160IQ friend said he had millions of files on disk basically has no idea where anything is... Learns everything from memory as he reads it before he goes to next things... It is really dumb in information age, so much interesting things from what we read is permanently lost, there is no really good way to capture info and link it and bring it easily later... Just diet, or healthy lifestyle can be complex and many different areas that are related and are under 20 other things... IT is impossible to find something later... It is absurdly bad how devs don't realize these things and normal ppl tell you you are crazy if you have over 10 tabs, while it was shown today work can generate easily over 100 tabs and it is important to manage information well... Yet there are no solutions, would have to hire programmer for every small thing i notice somewhere is missing, or is vehement useless basically...
