I run Firefox Developer Edition.

I recently added some lines to my hosts file (C:\Windows\System32\drivers\etc\hosts). Despite these additions, Firefox ignored the hosts file and loaded the pages I had blocked just fine. So I tried a multitude of options like disabling "Enable DNS over HTTPS" and eventually I got to work and the hosts file was respected.

So after thinking about it for awhile, I actually DO want Firefox to ignore the hosts file like it did before I made the change. I reverted the "Enable DNS over HTTPS" setting to its default of enabled, and I've tried everything else I can think of, but I just can't get it to work.

How can I configure Firefox to ignore the system HOSTS file and load blocked pages anyway?

Could really use some help.

Hello, We are developing an extension which is built on manifest v3. Right now in the firefox MV3 is not available by default and user has to enable it manually. I wanted to understand the timeline for the MV3 release. So that we can decide to support MV2 or not in our extension

I found the hidden page where you can "manage" cookie exception rules, but there's no way to add rules, or remove them, presumably, if you found a way to hack them in.

Every time I work on the local environment a lot of my extensions go crazy on localhost, throwing enormous amount of errors. This makes console barely readable. Is there a way to disable messages thrown by extensions in the developer tools of Firefox Developer Edition?

Similar to this in Chrome with "Selected context only": https://superuser.com/a/1346827

Thanks.

I have a laptop with Ubuntu 22.04. Firefox 307 from deb package works perfect. I wanted to give a try to Flatpak variant 306, which works well too, except two finger gestures back and front won't work. Scroll works. Any scheduled fix for that? Would be cool to move to flatpack completely.

I've recently been having troubles playing videos on Firefox.

My school website uses Vimeo embeds, but recently when I've put the videos in fullscreen, after 4-5 seconds it stops responding. The video freezes but the audio continues, and the controls don't come up when I move the mouse. I can press ESC to exit fullscreen, but the controls are still gone and the audio keeps playing. Then after a few more seconds I get the warning "This page is slowing down Firefox, to speed up your browser stop this page".

If I don't use fullscreen but instead zoom in on the page, it also freezes. If I try the same things with Edge it does not freeze. I also made sure that it was only affecting Vimeo videos, by testing with other platforms and other vimeo links.

I found previous reports of this issue, but all of them were either on Linux, or it was an issue with flash player, which is not relevant anymore.

Not quite sure how to debug this but I would be happy to provide further info. It's really important that it works again :/ Thanks in advance!

My repro steps: 1. Find a video on https://vimeo.com/watch 2. Play it and enter fullscreen 3. Wait around 6 seconds

So this would be a question about a situation that I have been involved with before and any attempt at finding a reasonable solution that would help resolve this dilemma has been quite difficult to find. And so, I will paint a portrait of the scenario:

So hypothetically, let's assume that <User> has Two-step Authentication activated on Mozilla Firefox and is on a weekend excursion of the Mighty Mississippi River and so happens to lose that phone to the surging undercurrents and a tumultuous exodus to those murky depths, but On Top of This Person's Game, quickly attains a new phone (yet in a moment of rushed deliberation and penchant to make some minor miscalculations (to spice things up, of course) couldn't keep the old phone number.

And so, in the course of updating the newer phone version and the number on numerous sites and has arrived at finally updating Mozilla Firefox account, which asks to Two-step Authenticate by sending the code to the bottom of the Mississippi River (or some bull shark's belly (who is most likely very confused about why his lunch is buzzing and starts to be concerned about his own gut health issues).

And so, the Issue at hand is, how does one get thru the Two-step process, which only seems extremely eclectic about sending codes to that ex-phone instead of paying attention to this newer, younger phone version.

Thanks in advance, - Lost in a River

I have recently updated my site to run off a different hosting provider, and CloudFlare, a long needed change to my site. However, in doing so, my site has become unreachable on my laptop, with firefox (and other browsers) still thinking that my domain is attached to the old nameservers, causing it to redirect to the "site not found" page of my previous hosting provider. I have tried flushing my system's DNS cache, clearing my browser cache, clearing the browser's DNS records, all to no avail, however, I do know my site works, as on my mobile phone with basic Safari, the site works fine.

my system is on Ubuntu 22.04, and running firefox version 107.0

Lately every time you release an update you break something in how Amazon is displayed. Not on all pages, the initial main page is fine, but if you try and view any lists or past purchases the display is unreadable. I've noticed this in the past, but this time it happened right after your last update, so I conclude that's where the problem lies. The attached screenshot is of my Amazon Wishlist. If you have one of those you'll notice the appreaence is way off. And BTW I was trying to delete the list, or perform any of the other actions that result in those warnings. Thank you.

Hi, My 2019 16" MacPro crashed when I downloaded the new Ventura OS. Only fix, per Apple, was to wipe the disk clean and reload the OS (Ventura 13.0.1). I reloaded and I lost my Firefoz and all the bookmarks I had. I need to retrieve them. How do I do that?

I am blocked from my account on PJMedia. PJ says the problem seems to be with Firefox since I can get in using Chrome. This is the message the mail system returns: Undeliverable: Delivery Status Notification (Failure) Mail Delivery Subsystem <mailer-daemon@googlemail.com> You Message blocked Your message to pjmediavip@townhallmedia.com has been blocked. See technical details below for more information. The response was:

Message bounced due to organizational settings.

Any suggestions? PJ seems unable to resolve the issue.

Operating System Windows 10 64 bit firefox version 107.0

having issues with an anime website watch cartoons online, most of the episodes, on several anime(dubbed) state "timeout err" and then say unable to play vid, refresh, but no matter how many times i refresh none of the videos that i know should work are working now. i have no add ons at all, as far as im aware, no pop up blockers, no viruses detected on computer, and now at wits last end trying to figure out what the problem is...

Ever since I loaded version yesterday Firefox periodically crashes when undertaking normal functions. For example I will load a set of tabs that i have been loading for years and now doing so causes a crash. Worse still of the 8 to 10 crashes I have experienced in the last 24 hours only 2 are recorded on the "about:crashes" feature and one of those fails when you attempt to submit it.

Now this has only started hapening since I upgraded to version 107. It is clearly somerthing to do with that update and the only further thing I can think to do is a full reboot in case some rogue process is interfering with the new version.

NB Please note I'm not interested in excuses about add-ons and the rest being the problem. it was this update that has destabilised my browser. Your Update. Your problem. Own it.

I have 3 PCs with Firefox. The bookmarks and bookmarks toolbars were all synced but one machine required re-installation, and now I have a fresh Firefox and have forgotten how to import the bookmarks and bookmarks toolbars. I don't seem to have any password for Firefox sync and I can't find where and how to import the bookmarks. Can anyone help?
