Speed test on a freshly booted machine is 100/100Mbps ... very often after viewing a youtube video in Firefox, this Speed test can slow down to below 20Mbps which results in a poor streaming experience ... I have a 150/150 fiber connection and the modem speed test doesn't change ... nothing to do with anything downstream ... not running anything else except FF ... always running with the latest up to date version(s) ... things of note: the process count goes up when this occurs ... even if FF is restarted it doesn't resolve this issue ... only a reboot resolves the issue ... when rebooting there is always some UNKNOWN process that needs to be manually terminated before the reboot process runs.

I suspect one of the multilayered (FF appears to open multiple sessions with streaming) processes may be getting widowed and left running and not releasing resources which causes less and less bw to be available ... this appears to occur mostly if I either Fast Forward or try to click forward or backward on a stream timeline suggesting to me that the current timeline may not be closing properly ... process manager doesn't reveal any processes linked to firefox but there are numerous svchost processes which I expect may be involved

Are there other ways/tools to narrow down this issue so the Mozilla team might be able to fix this ... I use FF exclusively but this has become more and more of an annoyance.

My i7 2TB 2.6GHz 8GB laptop is unable to move beyond W7 64b pro but I have had the same experience on a W10 64b Pro machine so very skeptical that this is an OS related issue.

Ultimately if FF kept track of the PIDs it opens it should be able to force them to close if they refuse to close on their own. Kill Process tree ... or ... perhaps provide a log that is user accessible identifying opened PIDs so that a user could manually kill widow processes without having to reboot.

I cannot stream china open tennis via tennis tv - login problems, crashing problems. Unresponsive to login details Sometimes I can log in but then cannot open specific matches Other times the screen just goes blank There is an account login icon in lower left hand corner of the screen, but if I try to refresh the screen the icon changes its nature and does not respond, then I cannot log in or out It is random and unreliable when I am trying to stream the tennis I have never had this problem with this website before, and I have been a subscriber for 5 years The first two photos are how the login icon should look. The third shows what is happening to the login icon The fourth photo is the blank screen that I sometimes get and cannot move away from - the screen is stuck I really dont want to have to use Safari and definitely not Chrome Sherrill Carta shcarta@gmailcom

When I am streaming TV shows or movies online using Firefox the timer in bottom left corner is is not going up by one. It seems that since the net framework updates in the past 3 days have updated in Firefox which is now causing my computer to act like a virus. The show will glitch and repeat 2 to 5 seconds worth of time. Seems you all need to check your crap with Microsoft to update your Firefox.

Greetings all

I had to reinstall Thunderbird on a new computer and I have been unable to send messages for one email ever since. The SMTP settings are correct. 993 for incoming port, 587 for outgoing. normal password. STARTTLS for connection security. I send a test email and it hangs indefinitely.

Ive been at this for 3 weeks and I am at my wits end. I disabled the virus security and firewall. I am really considering not using Thunderbird again its been so frustrating. Any help is much welcome.

Good afternoon. For the last day or so my Firefox has been running slower than normal. It takes longer to load my home page than normal, for one example. Actually it takes a little longer than it had to load most web pages. I tried opening the same pages on Edge to make sure it is not just an internet issue and Edge works fine.

I am also having an issue with settings. When I open settings, privacy, and navigate to saved logins before when the list would automatically populate it now takes almost 12 seconds to load all my logins.

I did try to run the browser in troubleshoot mode and the behavior did not change.

I am running Firefox 118.0.1. Any help would be appreciated. Thanks in advance.

Hello! I have a problem with latest version of FireFox (118.0.1). I have a website running at https://localhost:7230. And Asp .Net Core backend running at http://localhost:5205/, the authorization is configured to use NTLM.

From the frontend I call: const response = await axios.get("http://localhost:5205/Users/GetUser", {

   params: null,
   withCredentials: true

});

and it works in Chrome and in previous FireFox 117.0.1, but doesn't work in FireFox 118.0.1.

I've checked the request-headers, they are the same except for the version in User-Agent. I guess this has something to do with the security settings. I looked at the patch notes but didn't see anything similar to my problem.

What was changed in the latest version and how can I fix this?

Hello !! I notices a strange behavior of Firefox in my notification area of MacBook Air M1 running on macOS Sonoma 14.0. Many times when I am using firefox or minimizing it, it is showing "Firefox is capturing your screen" that can also be seen in attached image. I am not using any type of screen recording or screenshot too in any way neither having any plugin or 3rd party integration in browser nor any proxies. Sometime it also using the Mic and giving symbol of Mic use for few seconds. What's happening ? Can you please look into it.

I am able to use Chrome, so it is not an internet/router issue.

I have setup thunderbird to transfer 3 accounts emails to one new one in thunderbird but have run into some issues. It is roughly 400k emails across all accounts.

IMAP is turned on in all the accounts. I have tried going to one accounts "All Mail" and selecting all and right clicking on that selection to copy them all to "All Mail" on the new account - I get a message that it is downloading all these emails again ( in the bottom left corner) though I don't see any emails show up in that new folder. When I try a single email copy it doesn't show up there either.

I believe I am missing some sort of functionally ( IMAP or otherwise) that belies the UX instruction to copy an email from one folder to another.

Also I tried setting up a local folder and doing the same, and no luck there either.

In some instances I was able to get maybe 100 emails to move from one all mail to another though It was me trying this over and over and sometimes the number of total email would change to the right of "all mail"

Ultimately I want to download all my email locally, copy all these local emails to the local sync path for my new email account and hopefully have those sync up to Gmail via thunderbird. Do I have this process misunderstood, are there limitations and how would this be possible through other means if what I describe is incorrect?

the new gmail is setup to have the storage needed for these emails as well.

When downloading any file in Firefox (the picture is an example), the "Firefox" option will be added in the right-click open-with in Windows Explorer. This does not happen in other browsers. And this item is added without permission, it is a bad behavior.

在Firefox中下载任意文件(图中为一个例子),在Windows 资源管理器右键打开方式中都会被添加“Firefox”选项,这不会发生在其他浏览器上,而且一个浏览器未经允许添加一个打开方式是不好的行为。
