After I upgraded my system to Kubuntu 24.04 thunderbird started eating CPU (150+% CPU usage according to htop). Because I couldn't tell if the culprit was the new KDE or the old profile, I tried to create a new profile, blow away the KDE config, etc. I also tried downloading the latest version of thunderbird from the website. Nothing helped.

I was able to replicate this problem using the in-memory, fresh KDE.

To replicate: Create Kubuntu 24.04 install USB. Boot from this USB. When asked to install or try, select "Try Kubuntu".

Start Thunderbird.

When prompted to create an account, select cancel. Go into settings, to the bottom, and select Maildir for file storage. Quit thunderbird, and start it again. Create account (select configure manually, enter the information for imap and smtp host, STARTTLS, detect authentication. My username does not contain an @, if that makes a difference). Select "Re-test"

Try to read mail. You will quickly notice that Thunderbird is consuming > 100% CPU, and UI is non-responsive.

Restarting thunderbird does not help.

netstat -tupane shows one or two connections to my imap server port 143, but wireshark doesn't show any traffic on port 143

Not that I think it matters (since I can't get Thunderbird to start seriously downloading from the server) but I have a big ( >100G) Maildir behind my courier server.

Note that I see this problem both with the version on Kubuntu 24.04 install USB, and the latest version downloaded from the thunderbird website.

My Firefox on windows 10 crashes tabs OFTEN. Mostly is seems to be Facebook and YouTube tabs, but other tabs will crash and this morning, the Firefox start page tab crashed. I've done "refreshes", I've uninstalled and deleted the folder and re-installed, I've checked the SSD for errors. Nothing appears in the event viewer. Is there some way to definitively figure what is causing this?

I just reinstalled FF because I was getting an XPCOM error message, and now, when I try to sign into my ATT.COM site, I get an error message that I can't get past; https://oidc.idp.clogin.att.com/mga/sps/oauth/oauth20/authorize?response_type=id_token&client_id=m14186&redirect_uri=https%3A%2F%2Fwww.att.com%2Fmsapi%2Flogin%2Funauth%2Fservice%2Fv1%2Fhaloc%2Foidc%2Fredirect&state=from%3Dnx&scope=openid&response_mode=form_post&nonce=PUKPnPRT

Prior to reloading FF, I did not have this problem.

When on a web page or e-mail I regularly get a spinning multi colored ball which stops/interrupts the loading of the page. It will last for 3/4/5 seconds and then stop. What's up ??

You folks updated Firefox and now I can't open earmarked accounts. Reading all of the reasons is not helping me. I am not computer literate to fool around with settings. So can I go back to old firefox.

I am running Thunderbird Beta on Huawei P30 light and I do not get notificarion for incoming rmails. As far as I can see all notification setting are enabled. Please help.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

I feel rather obtuse asking, but how do I get my Thunderbird addressbook to sync to gmail contacts? I uninstalled Cardbook, because Thunderbird now does CardDav, I treid to create a new CardDav addressbook by opening my addressbook, selecting new addressbook, and going through the steps to give Thunderbird access to my Google account. But,

  no new address appeared in the list of addressbooks, and 
  the option to create a new addressbook is no longer avaiable/showing.

Addressbook is still not syncing. My server settings are IMAP. I still have three address books: All, Personal, and Collected.

I am flumoxed. John

YouTube only on Firefox has terrible stutter/frame pacing issues, most prevalent when watching 4k/60 content. "Stats for nerds" shows a healthy buffer and minimal dropped frames. This issue is not present when watching local videos or on Microsoft Edge. The issue can be alleviated by watching in 1080p60 but stutter/judder is still present. The issue is not resolved no matter what power or performance options I choose in my laptop's settings. Any help is super appreciated, as I really don't want to open Edge every time I need to use YouTube. Thanks!

I've noticed since a few upgraded of Firefox tat I am having an issue loading my local uTorrent GUI at: https://192.168.0.xxx:36724/gui/index.html. I am currently using 132.0.2 x64 and it eventually loads after 3-4 minutes. There are absolutely zero add-ons at the moment, and it does not matter if it is a portable version or standard installed version. I do not seem to have this issue while using Firefox (latest) ESR portable version.

Is there something I'm missing here? I am not sure if it is the port that's the issue with Firefox, because I have a local website using port 9090 and 8080 without any issues on loading. Also, it is happening with the nightly version of FF as well. All other browsers load quickly.

Kind regards,

Bonjour, La zone de saisie et de recherche d'un mot sur le site du dictionnaire de l'académie française ne fonctionne pas.Elle fonctionne bien sur d'autres navigateurs ???

Hello, Yesterday, when I turned on my computer, I couldn't use Mozilla browser, it keot asking me to refresh it. This happened with other broswers too and they would all open new window with every search, instead of new tab (despite the option being unchecked). I reinstalled Mozilla and that helped, not just for Mozilla but weirdly enough, Chrome was suddenly fine too? Today I turned my PC on and I'm having the same issue all over again. Please help.

hello, i am having trouble fixing the context menu. im assuming the browser updated today and something broke because the context menu is now larger than my screen and 90% of the buttons are non functional. how do i get it back to how it was previously. there are at least 5 different buttons for "cut, copy, paste" and options for things ive never seen before like "reveal password, copy phone number" and options that look like they only work on videos like "speed and loop" and theyre on every site i right click on. how do i get rid of all the excess choices and revert it back to normal

Hello, I have uninstalled and reinstalled firefox twice using two different ways found on the community/mozilla website through chrome and I am still having trouble. It started a couple weeks ago when I received a notice at the top right hand of my firefox page for an update. I tried and it shows as Unable to connect. I tried various ways to connect with mozilla with no luck. I uninstalled, restarted my computer and reinstalled twice and still having the same issue. I lost all my plug ins and add ons after the reinstall and now I can't not even get them and can no longer sign into my firefox account through firefox. Anything that has to do with mozilla I can not reach unless I use chrome which I don't like doing. I have searched the community and nothing seems to help and I even submitted a help question in help community but no responders. Anything which I found addressing Unable to Connect was years old anyway. I can only assume it had to do with the update pop up which I never got to do and assumed a refresh or a reinstall would take care of it but it hasn't. What can I do? Thank You, Charyl

I saw else where disabling hardware acceleration fixes this, but how about you actually fix hardware acceleration!?! It exists so I don't have unneeded load on my CPU

Thunderbird is not working anymore. I can start writing an email but after about 5 min it dont take any characters any more. Its lagging and does out. Its in the draft folder and I ry to open but it will not work. If I just write a short message its no problem but as soon as I start write longer messages it will be trouble. It doesnt help restarting the computor. I use win 7 and the latest version. The problem started about a week ago. Writing this is no problem but if I would do it in Thunderbird it will not work by this long in the text. Best regards Stefan stefan@besthe.se

Hi,

The newest Firefox has an issue with properly parsing the javascript links in the ACS research journal articles. In these research articles, citations are clickable numbers in parenthesis. Clicking on them leads to a pop-up frame that gives detailed reference article information.

However, with the latest version of Firefox these citation links will only respond properly to the first click ever on the page. After you close the pop-up frame, any subsequent clicks on any of these links will have no response.

I attach an example article below. This bug has been repeated under Trouble Shoot Mode and I do not encounter the same issue with Chrome brower. https://pubs.acs.org/doi/10.1021/jacsau.2c00048

When I access chat.google.com and attempt to play a video that is uploaded to chat, it will not play. The built in player opens with a red play button but clicked it does nothing. These videos used to work up until sometime earlier this year. Most of the videos are uploads from someone's phone and they appear to be mp4. I've tried private windows, removing firefox along with all program data and profiles and starting with a clean slate with no luck. Other browsers play the videos fine, just not firefox. Attempting to play videos that used to work no longer work. Suggestions?
