Firefox Support Forum

Screen goes black when some videos play - audio continues, but screen is black. I am sire this is a Firefox problem - I have successfully watched videos using BING browser - same videos go black on Firefox. I have refreshed Firefox, cleared cache, restarted Firefox - cleaned cookies. Turned accelerator off then back on - because nothing changed. Does not do this with all videos, just some - some You Tube videos play, others do not. I have Windows 10 and McAfee Live Safe - all programs are current and up to dated.

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

FF 113.0.2 Win 7 64 Bit

When I read a pdf online it gets downloaded even though FF is set to always ask. When it asks I choose open with FF or open with Adobe Reader . Both downloads the file to my download folder. It doesn't ask what foder to download to even though I have FF set to ask where to download to in settings/general

I tried setting browser.download.improvements_to_download_panel to false as here https://support.mozilla.org/en-US/questions/1370494 but it didn't help

Hello Team,

On the Firefox browser I am unable to find the option where in I can log in to my account so that I can sync my passwords from the old machine.

Kindly advise.

I had to reinstall windows 10 (this was done by Microsoft with my permission) and so firefox was uninstalled (long with all apps). i have reinstalled Firefox, but can't retrieve my old bookmarks. I have a file of very old bookmarks, but the "import/restore" function doesn't restore or import using that file. Help please. Can the up to date bookmarks be retrieved from my uninstalled Firefox?

I am trying to move my mobile bookmarks from Firefox to Brave. I've synced them with no trouble from Firefox Android to desktop. I can see a folder in the Firefox bookmark manager called "mobile bookmarks", and it contains all my mobile bookmarks. From there, I can open them in Firefox, Brave, Edge, and Chrome. No problem.

When I click "Import and Backup", then "Export Bookmarks to HTML", I'm able to save the HTML file to whatever location I like - desktop, Downloads folder, etc. However, when I go to open the file, it only contains the Mozilla default bookmarks. None of the "Mobile bookmarks" folder is visible. The HTML file is only 11 kb.

Screenshots are attached. Using Firefox version 113.0.1.

FWIW, I've also tried directly importing the bookmarks to Brave using their import feature (not using an HTML file), and Brave does not recognize any bookmark files whatsoever from Firefox. Getting really frustrated.

console.log(new Date().toJSON()); console.log(new Date().toISOString());

// Actual output: // 2023-05-27T04:21:13.004Z // 2023-05-27T06:21:13.005Z

// Expected output: // 2023-05-27T06:21:13.004Z // 2023-05-27T06:21:13.005Z

This happens only on Firefox and Firefox Developer Edition on one of my PCs and not the other. Firefox is version 113.0.2 (64-bit) and DE is 114.0b9 (64-bit)

Anyone experienced this before?

Since probably 3 or 4 weeks ago Ebay through Firefox has been terribly slow. I have selected the option not to track in the address bar and still the same problem. I run ebay through MS Edge and runs perfectly. Happens to me in 3 out of 4 computers. Only in 1 works ok, very strange...

Speed connection in all of them is at least 200mb/s

Thanks.

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

Scroll down until you find "PERMISSIONS" and find for "Camera". Click on "Settings" that is parallel to "Camera". Now, select/type all websites, that you want to give permission/access to your camera.

Never used a webcam before, but i did that... the site is there, it says allow... i'm on the website now, says webcam not found... am i forgetting something? do i even have one? i'm at the library...

hello,

i've facing this issue for weeks. i've completely abandoned windows server 2019 as daily os and installed windows 10 with latest patches. installed firefox and firefox developer as usual and did my same settings for years. but videos can't be played on reddit, twitter and linkedin. i tried to refresh browser, disabled addons (only ublock and enhancer for youtube is installed) to be sure. but still got nothing. in my laptop with same addons and same privacy & security settings could play videos.

i can share everything that would solves the problem. thank you in advance.

I have a website that open pop-ups automatically using javascript. That is the expected behaviour of it. So I went into Firefox options and made an exception for that site. If I go to the site and wait so it can do its thing, it opens about a few of them, and then Firefox decides that the rule I have set up is garbage, and firefox decides to ignore it and block the pop-ups from the site.

Why?

Why on Earth does Firefox decides that he must do something against the rule that the user has set up. Why does it have this completely disrespect to the user settings?

I am honestly really mad at whoever decided that ignoring an exception from the user was the default behaviour.

Now, if someone knows enough what is going on they will tell me, go to about:config, go to this obscure command and change its value, value which I can't know without coming here and ask. If I create an exception, then I am in my right to expect that the browser should do exactly as the exception has been configured.

By the way I have tried with the troubleshooting mode and still happens.

These bugs have probably already been reported but just in case they haven't there's an issue where dates can't be viewed on Facebook posts without hovering the mouse cursor over the title of the post. The other bug is the cursor often, but not always disappears when commenting on posts.

Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

I noticed that on Facebook there is not shown data and time on every post. Some posts show this info, the other don't. I cleared cookies, deleted Facebook from history but it didn't help. On Chrome everything is showing normally. I put Firefox in solving problems mode, with add-ons off, it didn't help too. Any solutions?

I stupidly upgraded to the worst system in the world, Windows 11, and the silly animations caused serious strain on my device. I disabled the animation effects in settings, but now when I use Firefox as usual, the loading page icon animation has become a static hourglass icon, which is unfriendly. How can I enable the loading page icon animation while keeping the system animation effects turned off?

The title pretty much sums it up. I even tried drastic measures such as logging out then completely uninstalling Firefox and removing any leftover data on both platforms. After reinstalling and connecting to the Firefox account they will sync with previous data but any new data I add on Windows won't show up on Android and vice versa. I also obviously tried forcing a sync manually... I really wish I didn't have to switch to another password manager any help would be greatly appreciated! :)

I'm using the latest version of firefox, at the moment i had a trouble. Text of timeline zone of my facebook hidden, first timeline unhide but other timeline hidden. I'm restart my firefox, remove and resync ... but this error continue. I'm try other browser as chrome, brave no error. How to fix it? I'm the fan of Firefox but user experience too bad with this error I'm upload some images screenshot with error and no error with chrome browser. ++

I have always read downloaded .pdf files in Acrobat. I inadvertently changed the setting to "Open in Firefox" (I got a prompt and clicked it without intending to). I have changed the preference back to "Use Adobe Acrobat" in Settings/General/Applications, but Firefox keeps opening pdfs in a browser window. How do I get Firefox to abide by my preference setting?

Hello everyone. I do not know if any else has experienced this but I have several websites that I cannot sign in to. I have no problem reaching the sites but when it comes to signing in I either get a message that my sign in information is not correct and this happens on Bestbuy.com or I get this message on Chewy.com Access Denied You don't have permission to access "http://www.chewy.com/app/login" on this server. Reference #18.88dcda17.1684871617.2bce7d64 . Now if I use the awful MS Edge I have no problem signing in to either one. I have racked my brain to figure this out even disabling each addon which I only have a few. I have ran scans for Malware with Norton 360, Malwarebytes and MSERT and nothing there. I was hoping someone could shed some light on this in some way or maybe change a setting in Firefox that I am overlooking. I can access these sites fine and move around in them but like I said I cannot sign in into them. I would greatly appreciate any help.

Respectfully, DT
