Firefox Support Forum

This has been bugging me for ages. Happened on Windows 10 and now on Windows 11.

I start watching some video on YouTube or whatever, decide it's not useful/what I want, stop playing it, close the tab or navigate away, but if my device locks, the controls for this old, discarded video, that I didn't want to watch, are on the lock screen.

I wouldn't mind if it was a video I was currently watching but it's somehow remembering the last thing I started to watch. I can see no hint anywhere else that it's still active in any way at all.

The only way to get rid seems to be to close Firfox.

This is very annoying because it seems you can't watch anything without Firefox remembering it and putting on the lock screen until the end of the session, so it could be cluttering things up all day unless I close everything and (in my case, because of prvicy settings) delete cookies and log myself out of most sites.

I've tried multiple searches but all I've found here is a post about turning off media.hardwaremediakeys.enabled but I don't actually want to do that, I just want Firefox to forget videos when I've closed the tab or navigated away from them.

Elsewhere I found a suggestion to disable dom.media.mediasession.enabled but that setting isn't found.

Any help much appreciated.

Currently, Firefox opens OBJ files as text. I want to send them to the Microsoft 3D Viewer which is the default application in Windows for these kinds of files. All I can do right now is right click on the file, save the file, then open with the 3D Viewer. I have gone to settings/General then down to applications and I can't add any files there. (Why not?) It doesn't matter if I choose to save or open files, the OBJ file still displays as text in Firefox. How do I get Firefox to send instead of display these files as text?

I have two questions:

1. Will WASM and JIT be turned on or not affect the operation of RLBox?

I currently have the following about:config settings set to false, I'm wondering if this will cause the RLBox to not function?

javascript.options.ion javascript.options.baselinejit javascript.options.native_regexp javascript.options.asmjs javascript.options.wasm

I hope Mozilla staff will consider listing the operating status of RLBox in about:support, so that it will be clear at a glance.

2. Enabling "security.sandbox.content.shadow-stack.enabled" will cause add-ons to not function properly.

This setting seems to have been around for a long time. Is there any progress on this? Chrome has supported this feature for quite some time.

I would be grateful if you could help clarify this and inform me of the answer.

A few months ago my bank statement from wells fargo stopped showing the information. All I have are the heading and lines... no information. I was told by Wells Fargo it is a security glitch in the Firefox preferences. I was not able to find what they were referring to so I am contacting you for help. Instructions on where to find this would be greatly appreciately. It was something about unclicking encrypted security and that bothers me somewhat.

Hello! Hope you reader are doing well. Sometimes, I'll even dare say most of the time, when I browse YouTube on Firefox and enter a video - it loads fine (currently 😢) but the thing that says what the browser is doing right now - I don't really know how it's called, sorry - keeps showing, and the only way for me to remove it when it's stuck is to refresh the page. It is a small yet annoying problem, and been persistent through Firefox's updates. Thanks for reading and helping to make Firefox the best!

How do I fix this error message? The address wasn't understood Firefox doesn't know how to open this address An error occurred during a connection to www.wsj.com.

   You might need to install other software to open this address.

www.wsj.com isn't the only website where this happens. It seems random on sites. www.youtube.com, www.wellsfargo.com. It all started after the last windows update this week. my other browsers weren't affected. Firefox is my preferred browser. Help me fix this.

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

Running Win 11 Pro with the Firefox - 64 bit - All updated per June 9th.

ISSUE: Website tells me I have an 'add blocker' or the product 'addblocker' installed. I don't. However I get blocked even viewing my own website: fleksjobbernetvaerket.dk .... and others as well.... It's full of Google ads.

SOLUTION: I searched for how to solve this, but none of it is working, not even re-setting or re-installing Firefox, emptying cache, files and folders. I kinda gave up on this.

Hope you can help.

thanks Knud

I don't want to "update my software" every day. How can I turn this function completely off ? This continuous badgering makes me want to switch to another provider.

Hello,

Our ABN AMRO bank payments suddenly stopped working for a number of weeks. I cannot make any payment. ABN AMRO is compatible with Firefox. This has always worked well.

Please help me.

Thank you!
