There are many websites (I noticed with Google, Instagram) that seem to remove the list of previous pages. They obviously want to prevent that visitors go back (for example to the search results) and proceed somewhere else. The result is that I click on a link, the linked page loads and then clicking on the back button does nothing, as if I entered the URL directly into the address bar. I consider that a terrible user experience because websites are trying to control my options, even on domains before I reached their sites. Since one of the huge advantages of Firefox is the claim that that it helps users take back control, I hope that there is a way how to prevent visited websites from manipulating the history, which is outside their own domains. I am aware that I could open the history or type in the address of the previous page again, but it is just not the same as pressing the back button. Is there any configuration (or add-on) that could help? Thanks!

With the password settings for my domain, it seems to count the saved passwords as if they are for the same account, even though they are different. It also doesn’t show an image or label to indicate which account each password belongs to.

Twitterで使用されている「t.co」等の短縮URLにアクセス出来ず、「アクセスしようとしているサイトを見つけられません」とエラーが表示されます。 他のブラウザだとアクセス出来る為、Firefoxの設定の問題だと思うのですが、解消方法が分かりません。 解消方法をご存知な方はいらっしゃいますでしょうか。

Hi. I'm trying to migrate TB v. 141.0 Win11 to TB v. 128.13.0esr Kubuntu. I've tried copying the profile folder & .ini files over, but I get an error on Kubuntu about the version difference. I've not been able to work around that error, and the page it points me to seems not helpful (that may just be me). I'm willing to re-create each account in Kubuntu manually, but all my accounts have numerous sub-folders along with matching rule filters. I've ported the filters over OK, but I need to know how (if possible) to recreate the sub-folders en masse in Kubuntu.

Any help (including "You Can't") is appreciated.

Thanks Nick

Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

I am a user over at the Arcamax website I use it nightly to read the comics section for the last two days i keep getting an error message .

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I went into my system cleared out the cookies for that website still cant get into the website I switch over to Chrome and it works fine but slow as molasses.

My Thunderbird (version 115.12.2) is running on a Windows 11 system. My profile has multiple accounts configured as IMAP to multiple email services. I also have the Status Bar and Activity indicator enabled. Randomly, both indicators will show busy for an extended period of time. When I view this in the Activity Manager I see one or more folders hung for 10 or 20 minutes downloading one message out of several. This occurs in multiple accounts and servers.

I have researched this and attempted the fixes presented. I have cleared the cache files and compacted and rebuild email folders as suggested, but the slow update still occurs.

Then I decided to try and capture a ProMon.exe trace to see what is happening. What I found was Thunderbird.exe was spending all of the time while hung access the following file: C:\Users\MyUser\AppData\LocalLow\Intel\ ShaderCache\4a5eb0e65e559fc08e65ecb2fa9d650817ae895582a7a7ede162866d3e47a05a, like it was stuck in a loop.

When Thunderbird is operating normally, it is accessing this file but only for short period of times. Research says that it is ok to delete the files in this folder. I did that and it seemed to help for awhile. But it started happening again.

Does anyone have any idea what could be causing this? Is there a Windows thing to look further into? Any help would be greatly appreciated.

Yes, I have imap. not POP. I have the folder subscribed too also. Any ideas?

On my actual email server, I check my spam folder and i have a dozen messages in it.

Windows 11.

I tried adjusting the sort by options but it still is giving me the old date of the very first email in a chain. Along with all the other emails, I want the most recent timestamp of the most recent email on them. See screenshots attached

windows 11. Thunderbird latest version. Imap setup

Greetings! My Thunderbird email client recently mysteriously glitched requiring me to affect a repair to the profile. I can now access my email fine, but when I try to email a webpage from inside Firefox, I get and error stating in part: Thunderbird profile cannot be loaded, etc. I have tried what I could find via Google, but some is beyond my technical experience. Short of deleting Firefox entirely, and reinstalling, is there a simple fix that someone can suggest? I have backed up my bookmarks and passwords, along with the current Firefox profile folder, so perhaps uninstalling the program and reinstalling may be the best route to take? Thanks in advance for any assistance.

When I open a website, for example, "Instagram", a window pops up with an offer to open in the Instagram application, I open an app store, not an Instagram application

Signed on to Thunderbird a couple of days ago to see a message about a new release. Seeing no way around it, I went for the update. Thunderbird now opens to a screen asking for an account setup. Name, email, and password--which I assume is the main email server (AOL in this case). I fill this in, click on test, and Thunderbird comes back with an available POP3 configuration it found, which is not the one I have been using for several years. I try it out, Thunderbird tests the password and finds something in the password or configuration that doesn't work. I try a manual configuration the the correct pop3 and smtp addresses and get the same result. I am at a complete loss at this time. This is all I get when I try to open Thunderbird--none of the usual email boxes, calendar, contact screens at all. I cancel the setup and get an option to continue and potentially not have access to some features, or exit. I click on exit and a new screen opens with file tabs for email, calendar, address book, and tasks. Looks nice, but there is no data brought forward on any of these tabs, and email looks like it has not been set up (no surprise--no inbox or preview box).

Any ideas on how to complete his setup and bring the data in, or on how to go back to the previous release and uninstall the new version?

I add this to my settings question of earlier this afternoon but I don't think it's settings. I signed into att at 5:45 to find four identical messages from att about a sign in at 5 pm (which was me). Then I went to Thunderbird and, instead of my mail boxes under my email address, there were three empty folders all entitled !%26! followed by an endless string of capital As. Have I lost every thing? Have I been hacked so quickly? Can I recover my mail boxes?

Hope I hear from some one. Thank you. Marjorie

I don't know how to retrieve my prior question which was about Thunderbird not being able to retrieve my messages even though I had thought I put my new att password into the right spots.
