Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

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?

Where can I get the bug fix for email jumping in the preview window? I understand that the fix has been created and tested. I downloaded what I think is the daily build, but, When I attempt to install it, I am told that I require windows 10. This is getting very aggravating. What took an hour before the upgrade now takes at least three hours for reading my email.

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.

Hello- I am having a very strange thing when using Firefox. I type and certain letters pop that I have not typed. It is different letters that are affected. it has been the E a number 2 shows instead s a m shows instead. There have been others but I did not make note, My solution is to close firefox and reopen. I have updated to newest version. Do you know why this is happening and a better solution. Also when I go to Chrome the letters do not transpose. HElp Stephana

I need a button to get immediate check of my email inbox from my provider. The old button has been replaced b y a NON-FUNCTIONING button which offers the key alternative alt-1, which also 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???

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.

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

When writing an email if I use the 'Insert>image' menu route the whole thunderbird app freezes (using win10, fully updated). However, if I manually copy and paste to insert an image via the clipboard, it seems to take OK. So have a workaround now, but worry the program route is failing. Am I missing a setting somewhere (I must say I have experienced glitches* since updating to the newest supernova version - 115 - and wishing I'd just stayed with the older previous version a while longer.

• Other glitch is the system is endlessly demanding passwords for my hotmail accounts when checking email (not so for the yahoo or gmail accounts). Very frustrating and time consuming.

Thanks for any advice Ken Dutton

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

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

I've been having this problem for a couple of weeks now. When I go to certain websites (that work on Every other browser I use) I get the following error:

Network Protocol Error

An error occurred during a connection to www.diamondtoolstore.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

It happens with Lowes & Home Depot - two sites I use every day for work. Now I have to use Chrome or Microsoft Edge -YUCK. I went to your help page and tried everything I could find that may help with this issue and nothing has helped. I see that there are a LOT of other people having the problem as well...Can you please fix it.

I have a client that is responsible for sending emails to all members of a board of directors on a timely manner. All members are on Gmail. The client is also on Gmail. She has created a list in Outlook to send a monthly document. Sends it to the list. Google refuses to execute and does not notify until a day or so later. Error msg says the bulk mailing rule offended.(Rule says it comes into effect when 2500 emails sent but balks at a list of 40...go figure) The solution I am looking for would send to the list members one at a time 10 seconds apart sidestepping the Google Bulk email bulk mailing rule. Is there a way to script and call from an email list?
