About 3-4 days ago, images no longer appeared inline and there isn't a button to show images, just an empty box. My T'bird is set to auto update, so not sure if an update caused this? Not sure if it's related, but at the same time, my rss feeds stopped due to "invalid security certificates." I did not make any changes to previous settings. Thanks for any suggestions!

FF loads so slowly and blocks so many sites that I had to disable enhanced tracking to get to mozilla.org. It can take up to 30 seconds for a site to load if I don't disable enhanced tracking, and even then, some won't load and will time out. I have 7 pinned items that load when FF opens, and it can take up to 5 minutes for all of those to load. Even on some sites where I have enhanced tracking turned off, I have to close the initial block page to get the site to load. Sometimes I have to stop the download and refresh to get the page to load. It is blocking sites that I've used for years with no problems.

What I have done: Troubleshoot mode - loaded a bit faster, but still had problems with some bookmarked pages I've used for years with no problems. It seems to hate all Google Pages, especially Google News Turned off Deceptive Content and Dangerous Software protection Turned off HTTPS only mode Turned off Block Popup Windows

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

Since the update to version 125 Firefox on Windows 11 (all updates installed), when I open a new tab and start typing to the address bar WHILE the VPN to the office is active, Firefox locks up and can not be used anymore.

In taskmanager, there is no spike in memory or cpu usage visible. All I can do at this point is to kill Firefox via taskmanager.

I can enter anything in the address bar of an already open tab with an other website open, I can open new tab from the bookmarks, but I can not open a new tab and start typing in the address bar while the VPN is active.

Once I disable the VPN to the office, everything goes back to normal.

I never had this issue on a previous version of Firefox.

Any ideas whats causing this?

After the latest update to 125.0.2 (64-bit) the browser works fine for a few minutes and then pages won't load. It starts working again after a restart [ for a few minutes]. I have cleared the cache & data. Chrome works ok.

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.

For some time now, e-mails have been arriving with a delay, e.g. from April 15, they arrived only on April 18. The mail is on the home.pl server pinned via IMAP.

Hi Guys!

Can high resources eatin' (maybe graphics, IDK) Ads, for Me in the Webside embedded and (sometimes) with 'movie' like movement decorated, automatically get blocked?

My phone runs slow, 'even' with just 1 Tab open and only Firefox Mobile App on the phone active.

Sorry, I can't see the field I type in currently, maybe I writ a bad layout right now, but content matters XD.

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Running macOS 14.3, Thunderbird 115.9.0

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

I'm having the same issue as previously posted below. I am on a Google pixel 7 pro.

"On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23). "

So with Google becoming an increasingly terrible company over the years I once again decided to try to move away from chromium based browsers and over to Firefox, but I'm still having the same problem as I did when I first tried. I have since found the source of the problem, or rather a more exact explanation of what is going on, but I still can not find a solution. Basically when I compare the audio of the same YouTube video while logged into the same account with the same settings the audio quality on chromium browsers seems better. After some testing I figured out that it has to do with Logitech's G Hub surround sound option. Using Logitech's surround sound on headsets that support it, the Pro X2 in my case, will change the audio quality by quite a lot, in my opinion it sounds better. The problem is that this change doesn't seem to have an effect when using Firefox.

Is this a known issue and if yes, is there a solution?

I am an e-mail packrat.... I have a pop e-mail but keep years and years worth of old e-mails (inbound and outbound) some with big attachments. My backup for the few e-mail accounts I have within my profile is approx 13 gigs. I've moved machines... and currently running Ventura on my imac.

I have to force-quit all the time to get my e-mail working again. It hangs-up.... sometimes will recover... but then... I type a few words or maybe sentences... and back to HANGING-UP again. Sometimes after a Force-Quit... it will behave for awhile. Other times... it takes 4-5-6 force quits in a row to get the program working again. Been having these issues for months... and have taken out all the add-ons etc.... HELP... pulling my hair out! Thanks

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

Firefox just stops responding when trying to load a web page. The only way to get it back working is to reboot the computer. I have tried quitting the application but when I try to restart it it doesn't respond and I end up having to force quit and reboot the computer and then it will work fine. MacBook Pro (15" 2017) MacOS13.6.6 Firefox 125.01

Any idea what's going on?
