I found out, that the getUserMedia Promise in Firefox only resolves, if the Tab is active or by clicking on the Tab Instance: (Firefox, 81.0)

navigator.mediaDevices.getUserMedia({ audio: true}).then(() => console.log("done"))

Otherwise, the Promise never resolves or rejects. Is this a bug or a feature, and where is this documented? Is there a media Config setting, to tell Firefox to allow getUserMedia Promise to resolve in non-active Tabs? Otherwise this looks like a bug for me...

Hi For some reasons im unable to access these websites zoopla.co.uk, rightmove.couk, mouseprice.com, primelocation.com, ebay.co.uk on my firefox 78.4.0esr and get the error SEC_ERROR_UNKNOWN_ISSUER with no option to advance. I can access these sites on Internet explorer & chrome but weird why Firefox is blocking it. Is there a workaround this please

Ps: i have no 3rd party anti virus and tried using this article https://support.mozilla.org/en-US/kb/error-codes-secure-websites but no joy

Thanks

There appears to be a bug in Firefox when I use this website, https://www.ourguide.com.au/tv_guide.php?r=melbourne&w=now

When you scroll down, the headings move right and show above the wrong information, see attached screen shots.

If you use this website on Chrome, you don't get the scroll issue so I think it is either a Firefox bug or something that needs changing in my Firefox settings.

I am running Firefox 77.0.1 (64-bit).

Any help would be appreciated, thanks.

When I go to the Yahoo main page, using Google and selecting Yahoo News - Current News it shows content but when you try to action anything it doesn't do anything and then shows an error. (see attached screenshots).

I have carried out all the recommended procedures including cookies, cache, etc and restarted Firefox with all Add-ons disabled and it still does not help with this problem.

I have used Yahoo for years and never had this problem and I have tried using Edge and Chrome and everything works as it should so it is definitely a Firefox issue.

So any suggestions on how to fix this would be appreciated.

Thanks.

Hello, I am trying to open a website on Mozilla Firefox browser, but continuous getting an error message "Your connection is not secure". Although this website is opening on other browsers. Help me to solve this issue as its lower the speed of my work. Please help

I was buying online from JB Hifi website, when I got to the checkout page, Firefox closed itself out. Tried several times and results still the same. I don't have that problem with Microsoft Edge. What is wrong? I recently had a virus scare & re-install Firefox. Thanks!

Hi, Firefox will not open on my PC as it thinks that it's already running. First off I tried a refesh but that didn't work as the same issue occured. I have uninstalled it and re-installed again but the same issue happens. A lot of the help pages I have looked at ask you to do things via the Firefox menu but as I can't even open a browser I'm unable to make cahnges.

Noticed on the latest release of Firefox after I press quit(I have multiple windows) the process will not fully close; I've confirmed this on both Windows and Ubuntu versions. It seems to happen when I have videos playing while closing as they will continue to play in the background.

Only way to fully close the app is to stop the running background process; the videos cannot be stopped as they are CCTV streams.

I'm not familiar with logging with FF if someone can advise on which ones would be of interest I can provide them.

Thank you Marino

On FoxNews.com, some articles include a section at the bottom for user comments. First-level comments frequently receive additional second- and third-level comments.

First-level comments are working fine, but lower-level comments are partially obliterated with a string of black diamonds with question marks �?U��N�@?�.

This is not an issue when I use Safari, but it is on Firefox.

I cannot logon to macys.com. I get the error message, "A technical error has occurred. For assistance, please call 1-800-289-6229." I called and rather than trying to troubleshoot Firefox, they told me to try Chrome. Chrome did work, so there must me an issue with Firefox. I cleared my cache, but still got the error message.

Hey y'all,

First, thanks for your attention. This has been driving me nuts over the last few weeks and if I can fix it I'd be very happy.

I switched to Firefox a few months ago and immediately set up the password manager and a bunch of bookmarks. Unfortunately, the next time I shut down my computer and restarted, Firefox said this browser was a new installation and had totally reset, with nothing saved.

This happened again a second time, so I set up a Firefox Account so I could have the settings saved to a profile rather than an installation.

Every time I restart the same thing happens: Firefox has a 'new installation' and none of my settings. The first time I logged in to my Firefox account to sync it, it worked. But I've just installed Catalina, previously using Mojave, and on that restart it happened again, but the Firefox account sync isn't doing anything. Now, every time I open up the browser, even if I haven't restarted the computer, it brings me to the same 'new installation' screen. When I log in to my Firefox account as prompted, none of my previous information syncs. Nothing happens at all after I get the "This Firefox is connected" screen.

I know the sync is at least somewhat connected because I can sync tabs from my phone to my computer.

Any ideas? I can re-do all of my passwords and bookmarks, but I don't want to bother if it isn't getting saved anywhere, or if I can't stop this factory reset whenever my computer shuts off.

I'm on a Macbook running Catalina 10.15 if that matters. Thanks!

I've been having this issue ever since the latest release of firefox.

Essentially it will be fine for a while and then all of a sudden firefox is unable to retrieve any headers from the fetch response. If I refresh firefox this fixes the issue, but only for a small amount of time. The same bug doesn't happen on chrome and I haven't had it happen to me yet on firefox developer edition. It happens if I use this browser on private browsing with no plugins as well.

Note that we do use a fetch wrapper but it essentially returns the entire response object in the screenshots below.

Also note that it doesn't seem to happen anywhere but localhost. Is there anything I can do here?

I'm not sure if this is a firefox problem or a Facebook problem, but when I click on certain links in Facebook Market place I get the above message. Other links that go to http://Facebook are fine, but the redirect on things like browse local, or reduced price kicks out this fb:// url. Also it seems like either I'm the only one to use these features or I'm the only one this is happening to because there isn't anything listed about it online.

It works fine on the FB app on my phone, but not on any of my PCs.

I have "the Enterprise Roots preference" problem. I followed the solution and changed the "security.certerrors.mitm.auto_enable_enterprise_roots " toggle without a problem. However, when it came to the "security.enterprise_roots.enabled" line in config... I show a lock and I am unable to highlight that function. Thanks for the help!!

I accidentally deleted the Blue start for favorites on the address line. I got it back but it does not recognize any of my previous saved pages. As of now I would have to re save all my previously saved web sites. Any way I can get back the original blue star and have it show my previously saved pages. Thanks in advance.

NOTE: if you look at the pic you need to X ot of the 1st pic. For some reason it is popping up in front of mine Sry
