Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

Recently, I switched to Fedora 39. At first, Firefox was working fine, but after I logged into my Firefox account, the fonts of some languages stopped rendering, and this started happening with almost every site that was using system fonts.

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

hi, whilst chromium renders it correctly, firefox struggles to cope with combining diacritical marks (two unicode characters instead of a single one - but should have look the same once rendered)

For the past couple of months I have been getting the message www.bbc.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR when loading pages on www.bbc.com website. I have done a search on the internet and it seems this is a common problem with Firefox and does not affect othere browesers. I have done what was advice given online but it does not solve the problem. It is getting so bad I may have to start using one of the other browsers even though I prefare Firefox.

You may have heard about this, Youtube (and parent Google) have recently declared war on adblockers and non-Chrome browsers. I have reason to believe they have escalated that war to deliberately crash non-Chrome browsers, at least slowing them down to make them non-responsive.

In the past few days, browsing Youtube has caused my system to stop responding requiring a power cycle to clear the problem.

Has anyone else encountered this problem? Is this just a bad setting, or is Youtube acting as malicious as I believe them to be?

We have an intranet site behind an Active Directory Federation Services (AD FS) - after updating the SSL certificate, the website will no longer allow Firefox clients to log in.

They will be prompted to sign in (with a default sign in prompt, not even the website login prompt), even if you enter the correct user/password it will continue to prompt you. The new cert works with Edge, Safari, and Chrome - I've enabled the following settings in about:Config network.automatic-ntlm-auth.trusted-uris, network.negotiate-auth.delegation-uris, network.negotiate-auth.trusted-uris, and set signon.autologin.proxy to be true - but the issue still persists.

Has anyone seen this/been able to figure this out? I've seen a few other posts, but no resolutions. Does Firefox not support Certificate Signature Algorithm SHA-384 With RSA Encryption? This is the only difference I can see between the 2 certificates; the original is SHA-256 With RSA Encryption.

Thank you!

Video on some websites is choppy after updating to a newer version of Firefox (115.8.0esr). I have attempted to upload a video of the problem but it seems only still images are allowed and this doesn't illustrate the problem. An example website where this occurs is https://www.fiat.it but there are plenty of other examples. It looks as if the playback is jumping forwards and backwards between frames. Strangely Youtube videos seem OK.

Some information which may be of use

OS: OpenSuse Leap 15.5 HW: Dell Precision 7510 with Nvidia Quadro M2000M video card and driver version 550.54.14

I have also noticed that when starting Firefox from the command line I see frequent messages like

Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index3/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/present Sandbox: attempt to open unexpected file /sys/devices/system/cpu Sandbox: unexpected multiple open of file /proc/cpuinfo

Probably not relevant but I included it just in case it is useful

Any help you can offer with debugging would be much appreciated, thanks

I am unable to open some pages in mypatientchart.org Page flashes and then I get an error 500. I've done all the easy things and everything is up to date. anyone have a possible solution? I am on windows 10 on a pc Program works properly in Microsoft edge.

I recently noticed a number of places on websites where a cursor would appear in a place where no keyboard input is accepted. I've narrowed it down to this:

Define a div like this: <div tabIndex="1"></div>

Style it like so: div {

 width: 200px;
 height: 100px;
 border: solid 2px red;

} div:focus {

 background-color: lightblue;

}

Click inside the div. It turns blue to show it has focus, but it also shows a cursor at the top-left.

This does not seem to happen when you use <div tabIndex="1" /> and it also doesn't happen in other browsers.

Firefox doesn't seem to handle date entries properly. For example, when I set a date on a website it automatically changes to something other than what I set it to. Sometimes it's off by a day, sometimes it's off by a dozen days. Sometimes when the site displays a calendar navigator (showing the year and a monthly calendar where you can cycle through the year and month to select a specific day on the calendar) there's no calendar to select from. There might be a year and month selector that I can cycle through but there's no calendar to make a selection. If there is a calendar and I select a date, a different date is displayed in the entry box. This also happens when I manually enter a date. I could type 3/8/2024 and when I hit tab or click off the box it will change to 3/6/2024 or something like that. It's not always the same number of days off. I could then enter 3/10/2024 to try to trick it, but it might display 3/9/2024. The issue seems to extend behind the scenes. For example if I'm paying a bill online the site will automatically show today's date as the day the payment should be made, and it will display correctly, but when I submit my payment an error indicates that the payment date occurs in the past. I have to change the date to a day or two in the future in order for the site to process the payment. I recently noticed in my Geico Timeline, where I can see a history of events, as I scroll, the dates will flicker to a day prior and sometimes they will stay on the day prior until I scroll again and it changes back. Only the day number changes, the time and year remain the same, and it's always to one day prior.

I've run Malware Bytes, Spybot S&D, and Windows virus scan. I've updated Firefox (set to automatic) and disabled plugins. I don't have the problem on other browsers.

Hello, Installed latest Firefox browser on a 2020 Mac Mini M1 running latest version of Sonoma. Firefox will not connect to internet. Error is "Unable to Connect". This happens on all websites.

Brave browser connects as to other applications.

Thanks for any help.

Hi, I've got a Wordpress website which contains some clickable links that run Javascript code. I have used obfuscation to protect the Javascript code and lock it to my domain. It all works fine for Microsof Edge and Google Chrome, but fails to display for Firefox. Is it normal for Firefox to not display obfuscated code for user protection or something like that?

This URL below will return a XML file in Edge/chrome but not in Firefox. I use Joomla as a CMS and it's extensions to display a RSS feed worked fine in both browsers until a couple of months ago. I've tried with a vanilla Mozilla/FF with all extensions disabled but still will not return the XML file

Thanks and ideas appreciated.

Hello,

I have been using CSS to change the looks in websites for a while. First, I use the 'inspect' function and then permanently make changes using Stylus.

For a month or so, I have not been able to apply certain custom fonts in either using the 'inspect' function or the stylus extension. Afterwards I tried the same on a fresh new install of Firefox Developer edition with no success either.

The problem in question is that I am able to apply custom fonts with names composed of a single word such as "Times" "Arial" or "Georgia", however, using fonts with two or more words such as "Arial Nova" or "Californian FB" does not work. Oddly enough, the system font "Segoe UI" does work, as to why perhaps this bug was not detected in tests.

In short, I am not being able to use custom css fonts with two or more words in any Firefox desktop setting.

When I try to do a search, I get (for example): http://search.sharedbuffer.com/s?q=ramadan+2024+dates&_pg=384D38AB-BE20-58F5-9DEF-070C21AEF0E3

What gives? How can I fix? Thanks

Dear Mozilla,

Please help your hundreds of users to access LinkedIn from your browser. This problem is going on for over a week forcing me and your community to another browser.

Soon your CEO Laura Chambers will know.

It’s frustrating and embarrassing to see Firefox help absent :(

After the last update of Firefox, I cannot browse to websites. Firefox simply presents a "New Tab" prompt as if it is trying to get to the website but nothing happens. Other browsers work flawlessly.

Any ideas?

Thank you
