Dear Sir or Madam,

I have spent several hours trying to troubleshoot Firefox slowing my CPU/mouse cursor but have found no solution. I have only three tabs open and Firefox is taking nearly a GIGABYTE OF MEMORY! This is ridiculous and totally inefficient.

I made Firefox my main browser for faster loading times, which are faster, but then it trashes my efficiency by making my mouse cursor jump all over the place, lag, etc. I have 32gb of memory and a decently fast Ryzen CPU from only a few years ago. Gaming rig.

It makes no sense that Firefox slows down my Windows experience.

Please fix! I should not have to go through a bunch of troubleshooting actions to make Firefox not slow my PC down. I have seen many users complaining of the same issue.

Please fix.

Sincerely, McKay

Reside in Canada and access US bank account via iPad. Often bank will not let me sign in saying browser is not supported. Firefox is one of 4 browsers Bank supports. Bank states Firefox 115 or later required. I have Firefox 129.1. I have turned “Enhanced Tracking Protection” OFF; although, previos access/login has been allowed with it ON. I’ve enabled “Allow Cross-Website Tracking”, login still denied. When attempting to login, One is directed to the bank’s “Security” page that displays icons of the browsers allowed. Any suggestions please!

Thunderbird fails to opn properly and I get message "Unable to open folder mailbox ... because it is in use by another process. Please wait..." Waiting never ends. It is trying to load my default in box. If I try clicking on the Loading message £I get Thunderbird is not respondinng ,,..."

The Quick Filter is extremely slow on version 128.1.0esr (and also on 128.0.1). There is a thread about it on reddit. https://www.reddit.com/r/Thunderbird/comments/1e6hryp/quick_filter_is_super_slow_in_128/

There was a bug reported, and it is listed as closed (solved). When will this bug fix show up in the release version? Or how do I put in a patch? Thunderbird is almost useless for me with this problem. Here is the bug report thread: https://bugzilla.mozilla.org/show_bug.cgi?id=1908761

Thanks for you help.

Asked this question before but never received a response.

When someone sends me an email from their gmail account, thunderbird dopes not download it from the server. I use gmx.com for my email. All other emails sent to me are downloaded by thunderbird but not ones sent from gmail accounts. It is not a problem with gmail because if I use the web access, the email is on the server but is not downloaded by thunderbird. I have checked the filters in thunderbird, there is no reference to gmail.

The odd thing is that I have a second email account, also on gmx and thuderbird does correctly download the emails sent from gmail accounts. Any idea how I can solve this problem?

Sometimes when I save an email in my inbox to a subfolder it doesn't appear in the subfolder but when I search for that email search finds it in that folder. Why doesn't it appear in the list of emails in that folder?

Hi, Why do I have to click twice in a row on a message in the trash that I want to delete? This is how I do it: The message is moved to the trash and should be deleted from there. I mark the message in the trash and then click once on Delete at the bottom right. A window appears asking if I really want to delete. I then click once on Delete and neither the window nor the message disappears. Only when I click on Delete a second time do the window and the message disappear from the trash. What could be the reason for this and how can I fix it? Thank you for a useful answer. I don't have much experience with IT and Thunderbird. Regards Manfred

Adding gmail address to Thunderbird. Brings up the screen with the correct gmail address. I press allow, but message in Thinderbird is telling me wrong credentials. Dit all the tips I found, still wrong credentials. Fighting this for weeks on and off. Can't find the source of the problem. I am a Thunderbird user for many years, contributed money because I was(?) a happy user.....now I am frustrated. Please help me out.

The latest update to Thunderbird did all sorts of damage, but the attached image is one. My emails now look like they're a jumbled mess of code. Is there a way to reset or refresh these so they actually show the email?

I have a user/colleague who suddenly missed a few mails from inbox on Thunderbird 128.1.0esr (32-bit).

We already tried "repair folder (Rebuild Summary File Index) and that range of emails are not visible.

What other process we can execute to make visible those missing emails?

Thank you,

Emerson
