After rebooting a Windows 10 computer, and starting Firefox, two Firefox Windows open. The second one opens Yahoo on it's Tab with no other Tabs open. Before booting, there was only one Firefox window open. This has happened before in the past.

Could this be fixed.

I have also reported several times that at times, Bookmark folders are found missing but found in strange places where I did NOT move them. I have been told that this could be possibly caused because of my very large Bookmark file. It would be very nice if this was resolved. I have reported this at bugzilla.mozilla.org.

While I haven't encountered this problem enough to have sussed out what sequence of events causes it, Thunderbird will occasionally get into a mode where I can't switch windows focus. (See the attached screen shot of the Task Manager showing you can't "switch to" Thunderbird.)

When this happens nothing seems to work except killing the task via Task Manager. Not optimal.

This time - the most recent occurrence (today) - when this happened, there was an outstanding update. After killing the task and restarting I got the message "Thunderbird is installing your updates." Still not optimal, even if it is a critical update.

Thunderbird 115.11.1 (64-bit) - after update

Windows Info+++++++++ Edition Windows 10 Home Version 22H2 Installed on ‎2024-‎04-‎09 OS build 19045.4412 Experience Windows Feature Experience Pack 1000.19056.1000.0

At some point after a Firefox and/or Windows update, Firefox started to stall after working for a while. When I open Firefox, I start surfing using multiple tabs, using bookmarks, typing URLs, or clicking on web links and then suddenly, the little dot in the current tab where I am trying to access another link, starts moving right and left indefinitely, apparently waiting or unable to access the desired page. After that I type well-known URLs (such as google.com) that I know "always" work, and the same thing happens. From then on Firefox cannot access any URL I throw at it (no error messages or warning of any kind) until I close Firefox and reopen. Once I reopen, the cycle repeats: it works for a while until it doesn't. I have cleared all cookies and caches, I have erased or disabled all extensions, but the problems persists. Any advise? Thank you.

I have had this problem on two separate midrange samsung phones now: after about an hour of browsing, firefox slows down considerably. Pages take a long time to load and tapping input registers erratically, sometimes i tap a link and after a few seconds a different link opens, as though the tap was registered from a different spot on the screen. This is happening even on a brand new phone, and after emptying the cache. I wish I could keep using this app because of privacy concerns but it is genuinely unusable for me now. This problem has cropped up in the past half a year

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

Hello! I've been noticing for several versions of Firefox that the response times reported in the “Network” tab of the developer console are wrong. In Chrome it shows the true value, which are a few ms, while in Firefox they show that it takes several seconds!!!! I attach the images of the problem.

Is it a bug, or a configuration problem itself? Thanks in advance

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

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,

So I got a new ultra-ultra wide 32:9 monitor and I noticed when I have firefox maximized on my new monitor and switch focus to a different window all of the text on tabs on the full screened firefox would go very blurry. If I had the same firefox windows full sized on my 16:9 secondary monitor this didn't happen. I then tried having the windows not maximized on the new monitor and it did not do this behavior when it was occupying what I would say was 1/3 of the screen width but if I stretched the screen too far it would again go back to this blurry behavior. So it seems like the text for the tabs behaves differently after the firefox window is stretched to a certain width. On the non-stretched firefox windows the letters simply get darker which I find to look better than the blurring. I added a screenshot that shows the differences I am seeing, the firefox window on the bottom screen shows the blurring, if you look at what would be the left middle side of the screenshot, while the top and bottom middle firefox windows show what it seems like it should look like.

Thanks, Dan

I have been using Firefox as my preferred browser on Windows 10 Home and Pro systems for a considerable time and have recommended it to many Windows and Android users.

Windows 10 Home ver 10.0.19045 has recently been unable to access many well-known websites due to

Secure Connection Failed - An error occurred during a connection to <website's https url> PR_END_OF_FILE_ERROR.

There are multiple reports of this problem from 2023 up into 2024 in Mozilla support and across the web, but no solutions. Curiously all of the problem reports mention Firefox not any other browser. Suggestions to try multiple fixes, but none have resolved the problem.

One posting on Mozilla Support marked RESOLVED says the problem mysteriously went away for that user. Lots of people still seem to be having this problem, so how about a fix.

Sent from Brave browser,

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

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

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 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.
