I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

Good day Mozilla vols! Has anyone else heard of, or developed an issue recently where TB will not delete multiple emails when selected? Previously, when I selected multiple emails for deletion and clicked "delete selected messages", TB would hang for a bit (while processing), but then all my selected messages would be deleted from both TB and my mail provider.

With timing conspicuously aligning to the 115.10.2 update, the multiple email delete functionality has broken. Now, when I highlight multiple emails to delete, instead of deleting them, TB marks them all as read, and only deletes a single email (the oldest email in the group I selected).

I saw one other question about this, but it was marked "archived" without an answer. Any thoughts/suggestions would be greatly appreciated.

Mail provider: gmail OS: Win 11 Security: Windows Security (old Windows Defender) TB client (now) 115.10.2 Troubleshooting mode (with controls reset and add-ons disabled) did not resolve the problem

This is what the message says. It got hung up after the DONATE message posted. i donated, but it didn't free it up.

"Unable to open the folder Inbox on robert@perless.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again."

Apple says it is a TB problem, not an Apple problem. Somebody please help.

I am running this computer for my late husband who left us in September after he fell off a 25' ladder at the age of 85. It still has all the information from his art. He was a sculptor who made large kinetic pieces.

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

Samsung Galaxy S24 Ultra running latest Android update and latest Firefox update. I set Firefox as my default browser. I have un-installed all updates for Samsung Internet and removed all permissions for it. Disabling it is greyed out. Some apps that I use have links to websites. Too frequently, when I go to one of those links, the intro screen for Samsung Internet opens. Then, when I look at the settings in Firefox it is no longer set as the default. Then I set Firefox to default and go to my phone settings to see that Firefox is selected as the default. If I open the previously mentioned app and choose the web link, Firefox will open. But somewhere along the way, the default changes back to Samsung Internet and it's a vicious circle. I have posted in a Samsung forum but haven't gotten a reply that solved the problem. Please help. Thanks Mike

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.

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

I've had Thunderbird running for a few years now without any issue. Last week I upgraded from Ubuntu 22.04 to 24.04 and ever since that I've been having problems on Thunderbird sending email.

I can receive mails fine but if I try to send emails from any account I get "Sending of the message failed"

I've for 2 Outlook.com accounts and one gmail.com account and all give issues.

GMail I'm using: smtp.gmail.com Port 465 SSL/TLS OAuth2

Outlook: smtp-mail.outlook.com Port: 587 StartTLS Auth: Normal Password.

These settings have worked fine before the upgrade so think there is something broken my TB.

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

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

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.
