System Windows 11 - Firefox 151.0.3 All normal actions from mouse right click have disappeared eg open link in new tab or private window, copy, paste etc etc. The Settings General - Tabs has not changed and previously worked rt click ok. Any help to restore the rt click function will be appreciated.

Recently...large windows of received emails are showing up in the lower right side...and I have to delete or dismiss. Is there a way to minimize that option and not require me to respond? Formerly it would open as a small alert...and not requiring a response. Just went away, as I recall!!

Hello,

Based on this previous post https://support.mozilla.org/en-US/questions/1195138

I have turned off mousebutton.4th.enabled and mousebutton.5th.enabled

But I wish to bind these buttons to previous tab / next tab How can I accomplish this ? Thanks

Firefox has been automatically updated on Windows 11 and Tahoe, and now every time I close the browser, all tabs close – even the pinned ones – despite the ‘Open previous windows and tabs’ option being selected at startup.

Hello,

I have this problem. On only 1 PC from 5, with same mailboxes installed and same configurations, on one of the mailboxes, Thunderbird does not accept setting to "not read" the letter. I tried making time to read the letter and it worked for 10 min, and then again stopped. At final, no matter how it is set, when I push to read the message it always read it.

Tried repairing the folder, but doesn't work.

Any Ideas will be great.

Thank you

Greetings, Is there a way to change the order of threads in a folder? The all appear with the oldest message in the thread at the top and new emails that come into that bunch are buried at the bottom with no indication that they are there. I'd like to have the newest entry to the thread at the top and to have the threads with new messages highlighted until the message is read. Possible? Many Thanks

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

I am using Kubuntu 26.04 and I am using the monthly stable channel version of the Thunderbird Snap. In KDE system settings, the default email client is set to Thunderbird. Upon every startup of Thunderbird, it ask if I want to set it as the default client for email, newsgroups, feeds and calendar and when I click yes and close Thunderbird and reopen it it does the same thing, over and over. Otherwise the email program operates just fine otherwise. My email accounts are all setup properly and functioning and working and it downloads email just fine. It just has that annoying popup upon every startup. I've included two images to show what I mean. I like the Snap version and prefer that container format. I would like someone who is smarter than me to file a bug on my behalf.

Hver gang jeg får mails i min indbakke så kræves det at jeg sletter dem ikke bare en gang, men to gange, før de væk fra indbakken. Tidligere har jeg kunnet slette en mail en enkelt gang - som i alle andre mailprogrammer - men nu skal jeg som sagt dobbelt - slette dem. Hvad kan jeg gøre for at annullere indstillinger om dobbelt - sletning. Kh Flemming

Every time I boot up my computer firefox spams all of my previously opened tabs on my main screen. Due to the nature of my work, many of these windows are irrelevant to my work the following day. The only setting I can find to disable this behavior is already toggled off. Is this a bug? It's becoming really frustrating to close a billion windows every day when I come in to work.

I'm using the firefox instance packed in with Fedora, I believe it's a system package, not a flatpak.

How can I ensure that messages are always saved locally, along with images?

The IMAP protocol works fine now! How can I ensure that images in emails are always saved locally when the internet is disconnected?

How can I avoid constant requests to image hosts when I reopen an email?

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!
