منتدى دعم ”Firefox“

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.

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.

I'm working on developing a website that uses WebGL in it, but sometimes some bad code will cause WebGL to crash. The issue here is that once that happens, I have to go into troubleshooting mode and back out before it starts working again. Is there any way to make it so that WebGL works after it crashes?

i use Firefox as my browser, but AT&T Yahoo is my internet provider so I use a Yahoo home page and Yahoo mail. Last week they did an update, now every time my laptop goes to sleep I have to re log into Myyahoo to get my mail and my home page. It also seems to log me out of some of my other forums and websites at the same time. I'm not sure how to fix this in settings so any help would be great.

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.

For a few months now, I have been having issues with Firefox and my computer audio. If I am listening to something, like internet radio (doesn't matter which website), the audio will completely cut out. Sometimes it will start working on its own and other times I either have to force quite Firefox or completely restart my computer. When this happens, no other audio works on my computer. I have had a new motherboard, audio card, speakers all replaced under warranty. I've also re-installed Windows and it still keeps happening. Has anyone else experienced this? Can anyone recommend a solution?

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

Hi, Since the update today to 127.0 My sidebar bookmark will not load when I open Firefox. Here is what I have done so far,

Uninstalled Firefox and use the restore on reinstall. didn't work deleted the xulstore file in 3 location. didn't work Removed Firefox using Revo Uninstaller and installed from the local setup file. didn't work Uninstalled ad-ons that used the sidebar, IE Video DownloadHelper, Sync my account, and tryed the step above again. didn't work I use Revo again and did a search for any firefox file, deleted old firefox folder on desktop and any file I could find with a link to the browser. Reinstalled from local file.

When Firefox started this time there was no profile to log in my account "" password etc "", I did a test and the sidebar was working correctly. I then activated my account and the side bar stop working on restart. Not that I did a sync after removing a few ad-ons, see pic for left addons.

we did an update and having issues connecting to our Emr keeps saying not secure website but it is firefox is blocking us can someone call me [removed phone# from support forum] Nathalie

When I click on any link, Firefox opens a new tab but the site will never come up.

I've tried Troubleshoot mode and refreshing Firefox but something in one of the recent updates has caused me to not be able to click on any link and have it open. Troubleshoot mode will solve the problem for a couple of clicks and then the problem returns even while still in troubleshoot mode. Firefox has become unusable at this point but I'd like to go back. Please help.

Hi I recently upgraded to win 11 and was so happy that god listened to me and you've added PIP to your browser!!!!!! but I have few problems.... most of them I fixed on my own... I have the latest release and I'm using for now the developer edition. I used the regular too but I thought that the developer edition will be more stable. and its not... I needed to buy a new graphics card GTX 4060 OC 8GB just so I can see all the streams smooth without lagging I needed to upgrade to 24GB (I had 12) memory so Firefox will not crash my computer all the time. your memory consumption problem is ridicules!!! :(((( added a screen shot I have i7 4 cores. i ordered Intel XEON X5675 6 cores it should arrive in a few days just so it will be more stable. 1.from time to time it still crashes (submitted my crash report just now) its closing streams and i don't know why. is it Firefox? is it the stream website? is it my computer?? how can i pinpoint the problem?? 2. I'm seeing multiple live streams usually 6 or more with PIP , I'm organizing the layouts so that I can see them all together. I've sent you a screen shot. for some reason the streams windows keeps centering themself to the borders of the actual screen its driving me nuts. like it has a mind of its own. I keep moving it beyond the border so i can see al the streams but after a minute or two it keeps moving back to the actual screen border. sometimes it doesn't move. its like AI is controlling when it moves and when it stays. is there a way that a computer program!! will listen to my command instead of having a mind of its own and moving my stuff to where he wants too?? is there a fix to it???

Almost daily on Firefox, I get pop-ups like the one shown in the attached image. I have, a few times, bought items on MrTortilla's website and that's fine. What I don't want it pop-ups from them daily when I'm not even on their site. Where do I go in Firefox to say, "I'm not open to pop-ups from this site"? Somehow it must be listed as okay. Please don't tell me to delete all cookies because I like the prefills from most of them. If there's a specific cookie I need to delete, please explain how to get to that. Hopefully, it's just a setting somewhere of sites that are allowed to send pop-ups and I can be guided there to remove mrtortilla.com from that list. Thanks!
