OS: Windows 10 Pro 64-bit with all the latest Windows updates installed; running Windows version 23H2. Firefox release I'm having problems with: 137.0.2.

Just upgraded to release/version 137.0.2. The first time I open Firefox each day it takes about 2 to 3 minutes for ANY website to load. Sometimes when a web page does eventually load none of the images display.

I have tried same websites using Google Chrome AND Microsoft Edge. Websites don't have problems loading using either of those 2 browsers unless I have Firefox open in another window. If they load slowly, as soon as I close Firefox, web page load quickly in Chrome or Msoft Edge.

Not a RAM problem because I typically have around 20% of my RAM being used.

Did not have any of these problems using Firefox version 137.0.1.

UPDATE: Thought maybe it was one of my add-on/extensions so I checked for updates. Four needed updating. Made the updates and website still no loading properly.

I am now getting a spinning wheel with annoying frequency while using/trying to use Thunderbird on my MacBook Air 2017 running Monterey. Everything was fine for the first 6-9 months, but over recent months the spinning wheel has appeared more and more frequently while I'm trying to read mail, answer mail, scroll through messages, etc., etc. Now it comes up every few minutes and delays me doing anything for about 15-30 seconds at a time. It's really frustrating. I recently ran Onyx, which was designed to clear cache, etc and make everything run smoothly. But the only program it required me to quit before it started was Thunderbird. Is there some cache or something I need to clear on a (semi-) regular basis to keep it working at a reasonable speed without this godforsaken spinning wheel interrupting everything? Thanks for any/all your help.

I have Thunderbird installed on windows 11 and have the import export NG tools add-on. I have an mobx file locally that I am trying to import to thunderbird. I created a local folder and started the import but almost immediately I get this error: "TypeError: window.ietngAddon.mboxCopyImport is not a function", and the only thing that gets imported is the name of the mbox file, as a subfolder

Hi Mozilla, I'm a loyal and longtime user and have had no major problems I can remember in the last 15 years. Recently, however, I've found that over the last seven or so months I have had great difficulty managing my New York Times (http://www.nytimes.com) and New Yorker (https://www.newyorker.com/account/profile) accounts. I have had to update credit card information, change passwords and update personal information and I've only been able to do this by switching to an alternate browser (usually Safari). I'm constantly told that I should be using Chrome with them, which I DO NOT want to do. Can you find out why Firefox won't fully work with these sites? Thanks and Cheers, Jeb Blount (p.s. the last time I had trouble with this was about a week ago)

When scrolling on iOS, websites are jumping up and down whenever address bar appears. On some websites it isn’t a big issue (cnn.com), on some it is really annoying (Audi.pl). It makes it really hard to browse. See the video:

On Facebook, or other websites that have a text enter box that appears on the bottom, my keypad covers it and I need to scroll up to see what I've typed in and it Zooms back up to cover the text box as soon as I input a key. Whats going on?

A couple of weeks ago, following the last iOS update, my Firefox browser will not stay open long enough to use it. It keeps reverting to the home screen. I have had to remove it as my default iPhone 15 Pro browser because it won't work. The bulk of my passwords are stored in Firefox, and not my phone password, so I can no longer use certain sites without changing all my passwords to get new ones when I don't have access to my desktop.

I also have an iPad Mini, latest version, with iPadOS 18.3.2 installed. My passwords suddenly stopped working.

So I have two devices I carry at all times. I can't access my iPhone browser, so no passwords, and my iPad browser works, and it can't access passwords either.

I am hoping to avoid deleting and re-installing, so I don't lose my browser history, but I don't know what else to do.

Thanks!

I cannot tile my Firefox windows to left or right when I choose vertical tabs mode from settings. It works fine with horizontal tabs enabled. I am using Firefox 137.0.1 on Linux Mint 22.1 Cinnamon 6.4.8 with Linux Kernel version 6.8.0-57-generic, display server X11.

Thunderbird hangs immediately as soon as I click the Junk folder. Another issue that may be related to this. I posted a question about Thunderbird hanging in a few minutes after starting. It hung this morning when I was downloading the message. The inbox, which had hundreds of messages, became empty. After I downloaded messages again, it had over 6000 messages, most of which were junk. It seems the junk filter is not working now. Could anyone offer a tip on the remedy for this?

Videos from AcharyaPrashant.org are broken since past week and not playing on firefox Android, I've attached a screenshot of the same. But videos from the same website are playing well on the firefox beta app.

I do not understand why in the left hand side bar window I have listed both "Local Folders" and "Local Folders2". The problem is that when I go to look up something I thought I had archived I find it is not there. I thought the folder would contain it. However it got put in the folder either called "Local Folders" or "Local Folders2". I would rather there not be two "Local Folders". As it is now if I archive something and go to look for it, I won't know which place I archived it because both of those folders have the same listing. It is really confusing to me. What can I do so that I will only have one "Local Folders" listing.

Thunderbird performs a compaction. When it is finished the blue progress line is still showing on the bottom right hand side of the window.

You can select any folder and any view condition (read, all, tags etc) and no emails are shown anywhere.

• Restarting Thunderbird fixes the problem with no errors.
• This has happened a lot of times now and is consistent.
• If you force a compaction the problem does not occur.

Update: Usually, in frustration, I restart Thunderbird to fix the problem. This time, whilst typing this forum question, the problem resolved itself. I guess about ten minutes elapsed before the application righted itself. I will watch for the next incident and see what other information can be observed.

When I run firefox, the following commands lsof |grep -i firefox|grep memfd|wc -l lsof |grep -i firefox|grep memfd|grep DEL|wc -l produce values in the 20 000 or even 100 000 range.

For instance, currently with only 1 tab open - the form on which I type this question - I get $lsof |grep -i firefox|grep memfd|wc -l 19317 $lsof |grep -i firefox|grep memfd|grep DEL|wc -l 16362 And these numbers are still on the low side. In normal use (e.g., 10 tabs open), the numbers reach close to 100 000.

Some example lines of lsof: firefox 3883 135330 StreamT~s xxx DEL REG 0,1 27559 /memfd:mozilla-ipc firefox 3883 135325 Indexed~I xxx 156u REG 0,1 67108864 11945 /memfd:pulseaudio (deleted) firefox 3883 135325 Indexed~I xxx 160r REG 0,1 13192 78 /memfd:mozilla-ipc (deleted) firefox 3883 135427 StreamT~s xxx 132r REG 0,1 170 3110 /memfd:mozilla-ipc (deleted)

Although it may be a problem in lsof, this suggests that firefox performs a lot of memmaps that are later deleted, but are deleted in a way that leaves some left over state. Note that the "DEL" state in column 6 does not always agree with "(deleted)" in the right most column.

I first discovered this issue when my computer started failing with messages like pipewire-pulse[103898]: pw.mem: 0x55ce0273ac50: Failed to create memfd: Too many open files This could be a coincidence of course.

Current firefox version: 137.0 (but also occurs in other versiosn, e.g. 133.0.3) uname -r: 6.12.7-100.fc40.x86_64 OS: fedora 40

I have problems with my cannon scanner which Thunderbird originally solved . Now I have the odd problem especially Emailing the attachment which doesnt appear at the other end . Is there a help or support phone number or second best chat line i can get . i am a donator as it was Thunderbird that originally made my canon scanner perform properly . peterbunnett@gmail.com

Hello! I am writing a paper and for studying I open almost a hundred tabs. Here the browser starts to freeze already in the process of opening these tabs, it is impossible to work. fox, if possible, does not collapse tabs, this is good and at the same time bad from the point of view of working with a large number of tabs. android gets stuck after fox due to the excess of RAM use by fox. I would like some of your solutions for this in the future, other browsers do not have this problem. your browser starts to feel good again with these tabs if you enter it again since the tabs were collapsed by its restart. *my phone: Shark 8, 8/256GB, Android 13
