my firefox browser switches to how it will look on windows 7 for a split second and back to original view, i run it on windows 11 , also when i run multiple firefox windows minimized side by side it often crashes

Firefox spawn too many child processess, with cause the browser to freeze.

Proposed solution:

Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.

Example: 1 (maximal 3) child process per tab/window

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

Hello, Thank you for helping me with my email problem today. The issue that I am having is that whenever I try to send email from 2 - of my 3 - email addresses I get the following error messages-

Message from electric@triad.rr.com email.

""electric@triad.rr.com sender rejected. The email address you are sending as must match the email address you used to auth.. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your accound settings and try again.""

message from aristot@triad.rr.com email.

""aristot@triad.rr.com sender rejected. The email address you are sending as must match the email address you used to auth.. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your accound settings and try again.""

I did read and try the various suggestions that this forum made to someonme in reference to a similar problem. The emails did appear to match in settings for SMTP and I think I temporarily turned off my virus protection software. However none of these actions have solved my problem.

If someone would please make some more recommendations I would greatly appreciate it.

Thank you,

Please help me to understand why I keep getting the 'Gah! Your tab just crashed' message. This only started a couple of weeks ago, but is extremely annoying and makes me doubt the integrity of Firefox. The problem can be circumvented (at least for a while) by closing and re-opening Firefox, but I'd prefer not to have to keep doing this.

Hi I keep getting this error I know for a fact my password is correct, i can sign into hotmail.com just fine.

Why do I keep getting this popup?

Archiving emails to Local Folders is not working for me.

If I click the archive icon or press 'A', a new folder is created as required in my Local Folders/Archives, e.g. [Gmail]/Important. But the original email does not move, no emails are shown in my Local Folders nor do they seem to exist in the folders or files created: [Gmail], [Gmail.sbd], Important (empty) and Important.msf.

I have picked up that I need to set archiving options by identity as well as by account. The problem remains the same whichever IMAP account, which is Gmail and another smaller provider, or identity I use. Before I realised that, archiving did work - in terms of emails being moved to an archive folder within an IMAP account. But I want to download the emails locally to avoid going over provider storage limits. I've checked and Thunderbird can otherwise create new messages in Local Folders, e.g. when my network connection is interrupted it saves drafts there.

I'm using Thunderbird 115.11.0 on Ubuntu 24.04 / Wayland, and it's installed as a snap. Many thanks in advance for any help you can provide!

Hi All, I've been running TB on my home desktop since ancient times. Present config has been working for quite a long time. TB manages more mail accounts, of which two connect to my remote server (and two others to gmail and freemail). The day before yesterday evening there was a power blackout while I was using TB. Since then I have the following problem:

1. First mail account says: "Could not connect mail server <remote server>; the connection was refused". Now I cannot even see the sub-folders of this account in TB while the folder files themselves exist. 2. Second mail account (to the same mail server, to another mailbox) works partially, it says after sending an email: "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors."

Connection to mail server is via ssh portforwarding (for TB smtp is localhost:2525, imap is localhost:1143, ssh tunnels work as I can telnet to them and imap/smtp services respond). What is more, from the home desktop my wife (different local desktop user) can normally access her mailbox (different email address on the same mail server) with the same ssh tunnelling method. She was not logged in and was not using TB when the power crashed. After power had come back I ran fsck, filesystem is clean.

So I think that some setting(s) must have gone wrong under my TB profile and it is emphasized more by the fact that in the first case error msg the name of the remote server appears instead of "localhost". Account settings in TB seems to contain the original server settings (e.g. locahost, 2525, normal password, no connection security, etc.)

Only strange thing I could find in Troubleshooting list is that under "Mail and news accounts" it lists account2 (imap) localhost:1143 None Normal password while in the outgoing server column it contains _two_ times the locahost:2525 setting.

In config editor the mail.server.server2.hostname points to the original name of the remote mail server (instead of localhost???).

So what can I do if I wanted to avoid deleting the two mail accounts and re-configure them, especially considering the fact that the mailbox size is about 80 GB.

Any ideas are welcome and appreciated.

Thanks in advance, KEA.

Im using mozilla for long time but now its nit working https://showpm.com.co/ this site is not opening in mozilla please help me

I have been facing a very strange situation/bug (likely some addon breaking my Firefox) where I am not able to navigate/load certain sites and certain pages. Here are details:

What is working: 1. I can go to google, amazon, yahoo, and certain other websites home page, and type certain queries in the google.

What is not working: 1. I can't load Duckduckgo(dot)com, nor ddg(dot)gg 2. Though I can open Google(dot)com, but I can not search anything in Google. I can see autocompleted/suggested results in Google, but nothing happens when I click on those autocompleted/suggested queries (screenshot attached, see lower left corner, *.gstatic.com/*.google.com is loading forever). 3. I can't open any addons/extensions. For eg. Tab Session Manager, or even Bitwarden does not load when I click on it, except it shows a pixel on the right corner of addon button on Firefox Toolbar (screenshot attached for that pixel towards the right lower corner of the icon).

What I have tried already - 1. Firefox is up to date as of a few minutes ago. 2. Underlying OS is up-to-date as of a few minutes ago. 3. I have tried disabling all addons and it did fix the problem. 4. I tried changing theme (which was default black) to default, and it did not fix the problem. 5. Tried restarting PC and it did not solve the problem. 6. I tried troubleshooting mode and it DID fix the problem while I was in troubleshooting mode, at least sites were loading. But as I exited troubleshooting mode, addons started loading for a few seconds, and then once Firefox is loaded fully, I started experiencing the same problem. 7. Tried toggle HTTP3 enable/disable, which did not fix the problem. 8. Followed Firefox troubleshooting guides, it did not solve the problem (except troubleshooting mode). I tried disabling hardware acceleration and disabled any protection modes, DNS over HTTPs and other settings which might interfere in site loading - none of that worked.

My hypothesis so far - As I can access some sites on the internet, I have ruled out DNS issues and networking issues. I tried disabling all addons and it did not fix the issue (except when in troubleshooting mode) - which tells me addons are not necessarily a problem. However, I could not find what all things troubleshooting mode disables, and perhaps I should find that out. Could anyone please share any insights or your thoughts on what I might be missing? Firefox is my primary browser and a lot of my tasks are pending from over a day now. Any help is greatly appreciated! Thanks a lot!

Firefox just used almost a GB by just opening it! I only typed a Google search, and the next moment my phone tells my I'm out of data!

Note that this is foreground data, not background data. I googled and found answers about media playing in the background, but I haven't watched anything recently, so no streaming link should be active. I installed Ublock origin so I hope that might help.

Attach is my Firefox data usage for the past week of barely using it, except for an occasional Google search.

Every day on the second or third tab the website will not load. If I open firefox again the site will load immediately. These can be bookmarked sites previously used one million times or linked sites embedded in a current tab. Your support pages have not helped. I'm about to ditch Firefox MS Edge!

Hello,

I was using the latest version of Thunderbird 115.11.0. It stinks. It's slow and very buggy. It's the same on all my Windows 10 PCs. I have uninstalled it and went back to V78.13.0 (64-bit). It is MUCH better. And it retains features that were annoyingly removed in later versions.

Why do you keep "improving" Thunderbird when the older versions were perfectly good? Is this because you needed it to look "modern"? That's BS because it will look outdated by next year anyway.

Why did you change the configuration files? I had to re-enter my accounts and address book.

Are these "improvements" because you needed it to look "modern"? That's BS because it will look outdated by next year anyway.

Thunderbird is awesome two years ago. Now it's basically useless.

I am on a mailing list from the Smithsonian Magazine. I receive a daily email containing links to interesting stories. The links work and take me to the correct page, however, I am unable to scroll the page up to read the article. They used to scroll, but not now when I go there by clicking a link in the email. The email also contains a link named View in Browser, and the email appears in Firefox and I can scroll the email, but if I click on a link in that email displayed in the browser, the page still will not scroll up. Problem not present in Chrome or Edge. I previously reported this to Mozilla in Feedback and to the Smithsonian about 2 weeks ago, but still no change in his strange behavior. Firefox 126.0.1 (64 bit)

I previously enquired and was given a ticket number 150321. I later replied to say that the problem had gone away. This proved to be very short lived. The problem is that drop-down menus are blank. Thus clicking on "New Message" button produces a minimised blank dialog. Thus I am unable to send new e-mails. Clicking on other links such as help, tools, file etc produces narrow blank dialogs. I am able to continue receiving and reading incoming e-mails. Re-starting the computer sometimes produces a short term improvement. I am using an AMD 6 core CPU 32-bit operating system, x64-based processor I am trying to use Thunderbird 115.9 on Windows 10. It used to work, but the recent, continuing malfunction might be due to an automatic update, but I was not aware of the version number until the malfunction happened.

I just did a clean install on a new windows 11 machine. Every time I close Firefox I get a report crash screen from Firefox. When I close it and restart Firefox everything is fine, but very annoying! I have search every where with no luck for a fix. I did turn off my FSecure which made no difference If it continues I guess after all these years I will have to change browsers,which I don't want to do.

I am configured as follows for outgoing messages for Comcast: Details of selected server: Description: Comcast Server Name: smtp.comcast.net Port: 465 User Name: ellary@comcast.net Authentication method: No authentication Connection Security: SSL/TLS

This was the setting recommended by Tbird. Incoming messages are fine. What is wrong.

Hello,

I'm developing a web application. Yesterday I could access it with http://localhost:8000, then, I implemented https and it worked too. Today I needed to use http again for my tests, but everytime I type http://localhost:8000, Firefox changes it to https://localhost:8000.

I already tried to clear everything in the history, even the cookies, but it didn't work.

What should I do?

Also, could you fix this bug? I've found articles from 5 years ago reporting this issue, but the bug hasn't been fixed yet

For about the last month or so, I frequently get an error message that my password is incorrect.

I use Thunderbird to manage emails on five separate accounts. Four are gmail accounts and I NEVER have an issue with those.

The issue only occurs with my oldest email account, which is an ".msn" account - a paid Microsoft account.

I can send and receive mail on this account without any issues when I use Outlook online through my Firefox browser, but when I try to use through Thunderbird, I get the password error message more often than I don't. In other words, sometimes the emails go through, but most of the time they do not. When I copy and paste the text of the email into the web browser version, there is never any problem and I am NEVER asked for my password.

Every now and then, when the message pops up, I attempt to re-enter my password, but most of the time it still won't send, and the error message re-appears almost immediately. I have changed the password twice, but that has no effect on the error message.

I would be very appreciative of any assistance.

Thanks in advance,

Bud

Thunderbird is not even usable after this update! It crashes constantly trying to read and send emails. Can I go back about two or three versions back before you destroyed it?
