I want to sync my Thunderbird calendar on my win11 laptop with my new Samsung Z Flip 6 phone. I have a Google calendar on the phone, and I've ticked "Lightning" on it, but I'm not getting my entries transferred from my laptop.

Can anyone help, please?

hello, most probably we went way over what's supposed to be as regards thunderbird folders. one of these folders (with some 5,7 Gb content) finally sort of lost all its subfolders, sub-subfolders and emails. the files are there on the disk, but Thunderbird can't see them anymore. I tried to fix it with the available button, but after 8 hours it was still stuck at the very first step (don't know if there are more, really). also I searched online and found some interesting solutions, among which ne pointed at removing the panacea.dat e global-messages-db.sqlite files in order to force Thunderbird and rebuild its index. I am running v 115 though and there's no panacea.dat here. I wonder if there is any new procedure to get the same result... or else, whatever viable solution that could make me recover the former folders structure. of course, the first thing I would do after recovering would be to simplify the structure and/or reorganise in order for the folders to be less heavy, according to any suggestions of yours... that would be more than welcome :) thanks, kind regards

The 'Sent' file in my 'Mail' folder exceeds 3 GB (3,224,360,399 bytes) and is not being read in the TB Mail window. How can I reduce the size of this file AND save messages???

'Sent' message folder IS searchable!!!

I need help to figure out why Firefox is preventing me from going to websites I have used for a long time. Says it is a security threat. Won't even let me connect to Youtube.com

I need to put all my physics books marks into a physics folder. I created the physics folder without a problem. Then I went into one of my bookmarks and tried to edit the bookmark. It will say physics at the bottom when I switch the folder that bookmark is supposed to go in. But when I go back, the physics bookmark is not in the physics folder

Hello, I am suffering from an odd issue when using twitch.tv. In short, when viewing peoples streams, my video feed will usually turn into colorful static (aka "clown vomit"). I suspect that the issue is coming from Firefox, but I can't be certain. I am using a newly-bought laptop and the issue could be caused by a large number of things, theoretically. Here is what I know:

• When viewing on twitch.tv with quality 360p or higher, the video feed will usually (95%) become colorful static within 1 minute or less. When this happens, the video feed does not ever recover until page is refreshed or quality is changed. (I know a bit about video encoding, so this seems extremely odd to me, if it were due to a networking thing that lost some packets, a full-image frame should come alone sooner or later and fix things, but that never seems to happen)
• The video feed is far less likely to become corrupted when viewing at 160p, but can still happen.
• The ads may become corrupted in the same way that the main video feed can.
• When the feed is corrupted, the rest of the Twitch interface (pause/play, volume, quality select) is extremely laggy.
• When the feed is corrupted, if I pause the stream, sometimes the paused corrupted image is not completely stationary! There will be flickering in small portions of the image, looking similar to texture fighting in 3d rendering, flickering between two equally-but-differently corrupted versions of the image
• The issue never appears when using Chrome to watch twitch.tv. This is what makes me think Firefox is the culprit, not Twitch or networking or graphics drivers.
• Disabling my browser addons does not help.
• Private browsing window does not help.
• Clearing my browser cache does not help.
• I have had the issue happen on Youtube exactly once in 2 weeks, not sure if that's related or not, I think it was a normal "lost some network traffic but fixed itself the next time a full frame was received" thing.
• Video live streams on Youtube don't get corrupted the way they do on Twitch.

Can someone please give me advice for how to fix this? Has anyone seen anything like this before? Is there a way for me to get deeper under the hood of either Twitch or Firefox and more closely debug the video stream when it fails?

Hello,

I installed Firefox on my Chromebook using the Debian installer. I was able to right click the installer and click install. It's worked really well so far, but the only issue I'm noticing is that MP4 files have no audio and I cannot unmute them. The video plays fine, it's just set to mute and nothing I do will unmute it, including right clicking the video and toggling mute.

An example video that will play, but there is no audio: https://html5videoplayer.net/html5video/mp4-h-264-video-test/

To be clear, YouTube videos play just fine through Firefox, and the above video video plays fine in Chrome or even via Discord (which I also installed the same way, using the .deb file).

I'm guessing it's an issue related to Linux (maybe there's a codec that isn't available?), but if there is a solution that anyone knows about I'd appreciate it!

Firefox just updated. Now when I go to a website, right-click a link, and choose open in a new tab or window,it does nothing. If I left-click the link I can get to it in the same window, but when I go back to the originating page, it seldom takes me to back to where I started (which is why I prefer to open a new tab.)

The right-click menu itself looks wonky: There's blank spaces at the top, far too many options appearing, most of which are irrelevant to the situation or duplicate options.

This is happening in every site I've tried. For some sites I use this means Firefox is useless.

opening mail results in 'flashing' and not being able to see it. Headers sometimes do not match body of mail. Repaired folders several times, ran troubleshooter, uninstalled/reinstalled. Still happens. Flashes so fast you can sort of see the body, but it won't actually download. Took 10 tries to grab email # code to sign in here.

I've always used Firefox, always updated. Recently, some videos on YouTube don't play, but only a few... and videos sent via WhatsApp Web too, they don't play. But this only happens when I use a specific Wi-Fi network. On all the others, everything works 100%. The place where I use this specific Wi-Fi network is where I work, at home it works normally. Any idea how to solve this? On all the other browsers everything works normally. Sometimes the videos that don't play...if I close the tab and open a new one, they play...

'XPCOM IMPACTING MY ABILITY TO PRINT - I HAVE WORKED WITH SEVERAL SOLUTIONS NOTHING WORKS - i HAVE WINDOWS 11 MY SEARCH ENGINE IS DUCKDUCK GO WHICH I REACH THROUGH FIREFOX. WAYNE@THECRAWFORDS.COM SIGNIFICANTLY EMPLACING MY WRITING

https://connect.mozilla.org/t5/discussions/ios-18-2-link-sharing-to-firefox-mobile-is-not-working/m-p/81007 The issue is well documented above.

Prior to iOS 18 if you had a link anywhere in the phone be it WhatsApp, email, webpages in safari or text messages and if we long press the link to open submenu we could choose share - Open with Firefox. It used to work. This used to popup Firefox right away.

But after ios 18 update none of the options are working. If you choose open with Firefox nothing happens and if you choose Share - open with Firefox - open in background nothing happens. What’s the cause?

Perhaps in my opinion: Apple becoming territorial for their safari browser making it yet another corporate giant becoming greedy eih?

I'm trying to use a script which requires a question mark after the "dot com." I.e., if the url should be http://www.URL.com?custom_URL, it changes it to http://www.URL.com/?custom_URL. How to I keep it from changing the URL - and what is the point of jamming that slash in there in the first place?

This is my second attempt at getting an answer. Can't anyone help me with this?

Keep getting error message that "cannot open firefox because a copy if already open. Only one copy can be open at a time." And there is NO firefox app open. I tried deleting the app and re downloading/installing again, but that didn't work.

Help and suggestions please?

Firefox 134.0.1 videos keep popping up in new window automatically without user control

When I watch Youtube and I go to another tab the video keeps popping out a new window and when I go back to the youtube page the pop-up video collapses to the original window in Youtube. The same problem occurs in Rumble voideos so it has to do with Mozilla-Firefox browser & not the video sites. This behavior where the user has no control on "WHEN A VIDEO SHOULD POP-UP" on a separate window only has happened under the latest Firefox version. I don't have any Extension Add-on that may produce this behavior. It seems that the Settings only turn off completely pop-up videos If this is not solved I will definitely switch browsers. The user no longer has full control when a video should pop-up in a separate window. This should be a feature fully controlled by the user and not automatically by the browser. It is EXTREMELY ANNOYING. I've tried different settings suggested by other firefox users using the About:Config settings but none have worked. This is a major bug or a depracation of functionality. Please advice.

Thank You EM
