Firefox spawn too many child processess, with cause the browser to freeze.

Proposed solution:

Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.

Example: 1 (maximal 3) child process per tab/window

On my Android phone, the "close private tabs" notification keeps reappearing no matter how many times I tap it or swipe it away. Only way to get rid of it is by force stopping Firefox. Weird thing is that this issue doesn't repro 100% of the time either.

This is happening on Firefox 126.0, on my S23 Ultra running Android 14/One UI 6.1

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!

Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

Hi, Since 4 days all emails messages ending by ".... @akeonet.com" (SFR company) can't be sent or received via THUNDERBIRD. When opening THUNDERBIRD a password is asked for address email "lalevee.claude@akeonet.com". But the current password doesn't work. I'am getting then a demand to "try again" or "enter a new password" or "cancel" but again without any success. However when trying "Configure your existing address email", I'am getting the message: the email address ("lalevee.claude@akeonet.com") is found in the FAI data base MOZILLA ! Using AKEO webmail, I can find new messages received or can send new ones. Please notice, adresses ending by "...@gmail.com" are not concerned by this problem, and still working !??? Stopping firewalls doesn't solve the issue.

Thank's for your help. Claude

Hi, not sure the best place to ask, but it's been an ongoing issue since 2022. I kind of believe a shift in Intel has caused some of these issues, but probably not important (and I've already contacted them and did not get anywhere) at the moment.

Essentially, having Firefox running crashes the Intel UHD Graphics system, typically it is the UHD 620, but I believe I have some systems with a UHD 630. On Windows, I get a blank screen for 1.5 seconds, on macOS it crashes the entire Mac. I...I have a hard time wrapping my head around the fact I'm the only one with the issue and has occurred on multiple computers over a period of 18 months. The systems in question include the following:

Dell Optiplex 5040 MT - Fixed by putting a GTX 1650 in its 16x slot. Dell Optiplex 5060 MFF Dell Latitude 7290 Dell Latitude 7490 MSI GF63 (9th generation revision) MacBook Air 2020 w/ Intel i3 under macOS.

The thing is, with the exception of the MacBook, PCs don't report any issues apart from a "Hardware Failure" within the Reliability Monitor and the aforementioned screen shutoff. With World of Warcraft I'm able to reproduce the issue consistently under both DX11 and DX9, but Firefox not so much. I do see it occurring only on YouTube videos on the MacBook and is more common to occur on PC, but I have also had it happen on normal browsing.

I can turn off hardware acceleration and have done so, but I do wonder how much of an impact it will make on power efficiency on say, battery power. Would be something that should be fixed and I would like to put effort into getting it resolved, but I have no idea where to start. All drivers are up to date, Intel Boost is disabled (and I wonder if having it set as so causes this, though the MSI has no such BIOS setting) and it only occurs on Windows PCs with Windows 11.

Thanks for reading.

Hello,

I've been experiencing a great deal of crashes recently, mostly just with individual tabs, but occasionally the Firefox window itself goes down as well. I've tried reinstalling and refreshing Firefox, and I've been doing checks to see if my RAM or other hardware are faulty with no results so far.

I've mostly experienced the issue when playing videos on YouTube, but I've had crashes just casually browsing other sites as well.

Any insight would be greatly appreciated, and thank you in advance.

As of Wednesday afternoon my internal/system mic and speakers are no longer working with FireFox. Geek Squad says it's a problem with FireFox. I'm running Win11 on a Dell laptop that's about a year old. Firefox is up to date, and Windows should be as well.

Firefox browser doesn't load youtube's content, showing only grey for videos and text. The browser console shows a number of errors (I've attached a screenshot of the console). Even playing a YouTube video linked from a web site plays only that video. All other content is greyed out. Safari loads YouTube without problem. iMac 2017 OS is up to date, as is Firefox. What do the errors mean, and is it a problem with my settings? Thank you for any help

This is a recent change, and in fact I don't *think* there's a "missing message" problem after reading and watching for a couple of days. I *think* something has changed and Thunderbird reports having "downloaded x messages" even if it *just downloaded them a moment ago*.

So it may download 5 messages, then a few seconds later you hit the Get Messages button, and there are no actual new messages but it still reports "5 messages downloaded" but nothing new is shown. As of last week, it would have reported "there are no new messages" when you hit that button soon after having received messages.

So I think:

• there is no serious messages-missing problem
• there is a disconcerting issue with a change in how Thunderbird reports status where a message arrival state is "sticky" and for some duration after getting new messages it will re-report the count of the last receipt when asked to download when there are no new messages.

I could be wrong about either of these, but there's a definite change in a behavior that I'd gotten very accustomed to. It is alarming to hit the button, see a message regarding some number of new messages, and receive none.

I'm guessing others, like me, spent some time panicking, searching forums, repairing the inbox... I think I'm as interested in confirming that there isn't a bigger problem as I am in getting back to the accustomed behavior.

Hope this is useful; thanks for your attention!

Currently on 115.11.0 (64-bit) on Windows 11; first occurred at least one version prior.

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!

I'm using bandlab to link me and my friends who are hundreds of miles away to make music. Firefox and all browsers crash a lot with a "high memory usage" alert. But these are pretty big projects. I have 32GB RAM, this thing is crashing at much lower RAM levels than I would like for it to use. like 1GB seems to be the limit (i dont know that number if its exact or correct)

Is there any setting where I can INCREASE memory usage so I dont lose work from random crashes due to memory usage?

Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

Received an encrypted message but the content appears to be only my public key. Message not visible. Copy of same message was displayed in the clear in gmail on a computer that not set up to encrypt. Any suggestions gratefully received.
