I'm not sure when it happened, but somewhere along the line, Firefox stopped showing on-hover tooltips on unfocused windows. Clicking into the Firefox window again can disrupt what I'm doing in another window, however. For example trying to hover on the Firefox window with my mouse cursor, and type the text of the tooltip into a different window, while leaving the tooltip visible. Wrecks that idea!

I guess I assumed it'd be a temporary issue, that'd get resolved in a later update, without having to say anything about it, and I was wrong about that.

Any idea what's up, and how to get the tooltips to work as I would like them to?

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

Upon reopening Thunderbird mail today, I find that the latest update does not allow emails to be opened in a new window with one-click. Clicking on an email launches the message in a new tab instead of a window. Why create a new issue like this? DUMB . . . please fix.

Can anyone help please. I have tried everything but still fails. Sending of the message failed. An error occurred while sending mail. The mail server responded: Mailbox full. Visit https://aka.ms/mailboxfull for more information.; STOREDRV.Submission.Exception:QuotaExceededException; Failed to process message due to a permanent exception with message [BeginDiagnosticData]Microsoft Unified Storage is full.

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

I've noticed lately that my Firefox keeps freezing and hanging up at random periods for no apparent reason. I have very few plugins and it even happens with them all disabled and removed. I've tried resetting Firefox to default everything yet it makes no difference.

Also I can not clear history. I've tried multiple different clear history plugins but none of them work at all. And when I try the traditional way of clearing Firefox history the window pops up and then the entire browser just freezes while 'clearing' and never gives me back control, I have to force quit and restart to regain control. And then when I relaunch the history is still not cleared!

So aside from the constant lagging and lockups it seems that any attempt to delete history whether using the inbuilt function or adding plugins messes up the whole browser.

Googling this issue it seems others are having the exact same problem with Firefox and yet any suggested solutions (reset browser) don't seem to be working for may of them.. Or me.

I have a strong phone sd 870 and 6gb ram so need to put the blame on that.. but this browser keeps refreshing the webpage as soon as I leave to other apps.. yes I tried with no battery restrictions but didn't solve the problem

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.
