Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

Hi, I have an issue that is very annoying. I recently upgraded from brother HLL5200 to HLL5210 printer. Since that upgrade, all emails printed via logmein/thunderbird/brother printer are printing in 1/4 of the normal size (tiny print in top left hand side of page). This applies to emails I try to print, as well as attachments. I have no other printer, so I cant test elsewhere. Thunderbird troubleshooting mode does not help. Brother studied it and said its not a printer issue. Logmein studied it and said its not a logmein issue. My tech support guy thinks it may be a driver incompatibility between logmein and thunderbird. Can anyone help? Please contact me at nathan@nrosencanada.com thanks!

This morning Firefox stopped working for every website I attempted to access. The window shows the "Unable to connect" error. I'm currently using Edge for the Mozilla site help pages. I've tried many of the help article procedures, including: 1) Removed and re-added Firefox in the Windows Defender Firewall settings; 2) Scanned PC for Malware (Webroot SecureAnywhere, CE25.1), no threats detected; 3) Cleared recent history from Firefox. 4) Opened Firefox in Troubleshooting Mode but the problem persists. 5) I've also set the Network settings to "no proxy". Windows settings is set to automatically detect settings Firefox was working last night when I was installing an old version of Quicken 2015 (off-line/non-network installation). What's my next step?

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.

Hi

Long-term Thunderbird user and in the past couple of months Thunderbird on my PC on connecting to my mail server goes to a time out (about a minute?) before then downloading new messages. Connecting from my laptop is instant.

The PC - which is relatively new - performs well otherwise.

Checked settings on both and they are identical, save for the laptop.being 64-bit and the PC 32-bit versions.

Any ideas for me to try?

Many thanks

Rick

Hello Mozilla Community,

I’m currently using Firefox for my web design projects and facing some performance issues when testing websites built with modern frameworks. As a developer at DE IT SOLUTION where we provide website design and development services, I rely on Firefox for testing due to its robust developer tools.

However, I’ve noticed:

Firefox becomes slow when handling multiple tabs with live previews. Developer Tools sometimes lag during real-time CSS adjustments. I would love advice on:

Best practices for optimizing Firefox for web development. Recommended extensions that won’t slow down the browser. Tweaks for faster rendering of web pages during testing. I’ve explored Mozilla’s tips but would appreciate insights from this expert community. Also, if you’re interested in how UX/UI impacts web performance, you might enjoy this article from my experience: Why UX/UI Design Matters in Web Development (Sharing for learning purposes).

Thank you in advance for your suggestions!

Firefox hangs after starting with "session restore" After I click yes to restore the session firefox just hangs. So I just went right back using Version 138. I reinstalled from scratch still the same problem. At least the older 138 loads my previous session after hanging for 4 hours about and then everything works normally. The newest Firefox does the same, but NEVER resolves, it just keeps on hanging. Doesnt make any sense. What makes the system restore hang this badly. It cannot be old profiles. I completely renmed the old firefox install directory and cleanly installed firefox and it still does this. so it is not inheriting anything. I also allowed it to create a completely new setup in ./mozilla/firefox in the user account.

It also uses more than 117% cpu constantly during this period. See top entry.

Seems like I have to move to Thunderbird/Seamonkey or Brave. Since 2019, Firefox became very "strange"

Hi, I think there is a connectivity or audio code problem because when I'm using YouTube on Firefox browser there is a crackling sound on all videos (I am using smartphone and Bluetooth headphones). On Chrome, it is not present. Please fix it.

Latest update of Firefox 64, glitch is with attachments to Outlook Emails, cycles trying to open attachments for hours, cannot add attachments to emails. I'm using Chrome now because you software has problems. Help to get back to using FireFox.
