I've used FF for years and always had - "Open links in tabs instead of new windows" and "When you open a link, image or media in a new tab, switch to it immediately."

Until very recently this worked well.... now there are two identical tabs opening the link and the switch to immediately does not work.

For the last few days the ebay website is very slow when I open it. If I switch to Chrome, ebay's website loads okay. All other websites seem to load through Firefox with no problem. Any ideas???

Не отправляются письма ни из одного адреса через приложение Thunderbird. SMTP протоколы настроены правильно. Один из адресов использует стандартный протокол mail.ru, но письма тоже не отправляются. При этом входящая почта доставляется в нормальном режиме. Если зайти в почту через браузер, письма абсолютно нормально отправляются. Как решить данную проблему?

Hello,

we are a group of 9 people, organizing us with TAGs in Thunderbird (using same IMAP Mail). Before update to 115 version from 102 (I think) the tags were working flawlessly for more than 10 years. Now the syncing of tags somehow changed. For example if someone change the tag on received e-mail, on other computers the tag stays the same, until you click on that e-mail or until again a new e-mail arrives. That is very confusing because all the time you are not sure who's tag is selected or even more problematic that you untag someone who was already tagged. Before if someone tagged e-mail message, the tag was synced in next second, nevertheless at which e-mail were you standing. That was perfect!

I hope for implementation the option to manage tag-syncing time. Or can someone tell me if that's possible to manage that somewhere inside manual settings(Config editor)? I would also be pleased that somebody explain me how the tags synchronization actually works in latest TB?

Thank you all!

Hello,

I am getting a frequent freeze in the Android app and then shortly after a crash. Info: - happens on FF, FF Beta, and FF Nightly,and reinstall/phone reset didn't fix. - Samsung Galaxy SM-G965U running Android 10. - every error starts with java.lang.OutofMemoryError. - it never happens just on startup, just on auto fill, or some of the similar crash reports I've seen around here. - it does appear to be site-specific, but sometimes the site works and sometimes it does not: if I close the last tab after a crash, it will usually work for awhile. - Sync and disabling Add-ons doesnt fix it, although perhaps its worse with uBlock Origin enabled (not conclusively)

Thanks for any suggestions.

Open thunderbird up and want to print an email. Most of the time the printer is the default. Once I print and then go to the next email to print, the default printer is gone and the only option is save to PDF. I can close thunderbird and reopen it and seems to alleviate the issue for a few times then back save to PDF only. Strange issue. I have reinstalled thunderbird a few times. All other programs on the pc I print from always use the defaut printer.

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.

How do I find the email I click on? I search for something, I see the email in the list of results, I click on said email and instead of opening it, it bring up the ENTIRE thread that it is embedded in and I have no idea which one it is! PLEASE FIX THIS! It used to open up the email you click on within the thread. Now it just shows the thread. This latest update has RUINED the search function.

Using Nord Pass extension on Mozilla fine until today, when clicking on the green icon for stored username and password, this appears - "sudden error message : can't handle ITEM/URL_SEARCH type message"

For 8 months i am still getting tab crashed messages whenever i try to pause then replay videos. I have sent crash reports and shown them on the help page and get no real answers.

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Here is screen shot:

My iMac is OSX. I use Firefox browser most of the time. I had used Safari years ago. Chrome had rarely been used. Firefox problems recently began. Please help.

I have two mail accounts on Thunderbird. When I download messages to one account, the messages are automatically marked as read. Messages to the other account are not.

I do not use BitDefender.

Any thoughts on why it does it to one but not the other? Messages are both downloaded from the same ISP.

Since the UI upgrade, my Thunderbird client has become slow on my PC. On opening instead of what was previously a quick start-up to my INBOX, it now hangs and you can see (from bottom left) its polling out to email servers and waiting for a response .... much slower than previously.

It's not a server response as I use same email on my iPad and that logs in with almost zero delay.

Occasionally also lags behind key board, you are typing and you are several characters or even words in front of the client.

Is there any rebuild or similar I should do now I am on the 'new look'

I have recently started using Thunderbird 115.4.3 on a new laptop running Windows 11. I transferred my profile from my old laptop and set up my two email accounts as POP accounts. The problem is that Tbird is regularly crashing, mostly (maybe only?) when I delete messages from my Inbox. When I restart the program, it works fine except that all or most of the messages in Trash are now duplicated multiple times. Any ideas how to stop this behavior?

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD
