I opened my address book today and all my mail lists have disappeared. How can I get them back. I don't when this actually happened as I have not tried to use a list for several months. I suspect it may have been when I made the jump from 92 to 102. Running on win 10 on a PC.

Hi, I experience consistent tab crashes in my Firefox app on the computer since yesterday. It works only in troubleshoot mode and not in normal. I tried refreshing and reinstalling the app, installing Firefox for Web and nothing worked. Cleaning data and turning "false" preference media.wmf.vp9.enabled didn't work either. I also tried deleting all extensions, turning off recommended performance mode (using hardware) and enabling default theme. I haven't installed anything recently. Last Windows quality update 24.05.2023, last feature update 08.03.2023. Firefox app still works perfectly on my phone, so it's probably something with the computer. What can be the cause and what can I do to fix it? Added info about crashes below

Thanks

filters are not getting applied automatically after i start thunderbird or even when it is already on not getting any error it is just not happening have to trigger it manually every time kindly help thanks

I can no longer use Thunderbird with my Hotmail account. It keeps prompting for password several times then error comes up "server disconnected". I removed the hotmail account from Thunderbird, then tried to add it back in. It will not accept Hotmail account anymore, with same error about server disconnected. I am able to log in and use my Hotmail account directly from their, outlook.live.com without any problems.

As I receive new emails at distefan5@verizon.net, my older received emails more than about 3 months old are deleted. Most recent emails received that remain in my in box are from Feb. 2023. (1) How can I recover the deleted emails more than 3 months old? (2) How can I prevent this from continuing and keep received emails more than 3 months old in my inbox? Thank you.

Hi,

Since I updated to 102.11.0, I can't synchronise my Yandex accounts in Thunderbird. I get a screen to enter my credentials. It shows my Yandex email; then it requests I enter my password, and afterwards, I get a screen with the error message below:

400 redirect_uri does not match the Callback URL defined for the client

I'd appreciate your help.

Regards,

Celia

Good Morning Ace Volunteers,

For several weeks, Thunderbird crashes when I try to open letters with attachments and each time I try adding attachments to my outgoing letters. Every time.

On incoming mail with an attachment, I don't get a glimpse of the letter, let alone read the attachment. Instant shutdown. The preview pane doesn't display when there's an attachment.

Just now, I spent a good 15 minutes trying my best to access what a friend wrote, knowing the attachment wouldn't open. Though I tried every trick in the book, each effort led to an instant shutdown of Thunderbird. Never saw a word of it, just the subject line.

Stubborn me has been trying to diagnose and fix the problem when I could seek a solution from fellow Thunderbird users. It's time to ask for help from DemWhoWhat can fix this problem.

My sign-in email address for my Mozilla account is jiminlexky@yahoo.com. My principal email address is jiminky@windstream.net.

Thank you, guys.

On my new PC build I'm seeing a ton of instability with Firefox. It can go hours without issue, then have tabs crash 3 times in an hour. I've slowly trimmed down the plugins I'm using, with no change. I'm also using these same plugins on my 2nd PC without any issue. I'll just be sitting there, not even touching firefox for a long period of time, and it will have tabs crash.

Other browsers (Edge, Opera GX) aren't presenting the same issue under similar use. I've run a Memtest and seen no issues, although I'm curious if my Asus board is being problematic alongside recent reports. Its quite stable with gaming and Adobe suite, so I think I'm clear.

I've found no additional driver, windows, or security updates. Windows Security scan finds nothing.

Hardware info: 13900K in Asus Z790 ROG Maximus Hero, 4090 FE, 64GB DDR5 (6400 XMP). Hooked up via 2.5G ethernet to 2.5 Gbps fiber.

Summary: Firefox fails to load many sites, and some will kill the entire browser.

I recently updated from Ubuntu 22.10 to 23.04, which included an upgrade to Firefox. I originally had trouble with tab/window dragging operations causing the entire desktop to crash.

Removing the snap and installing from the Firefox maintained PPA fixed this issue, but a number of others remain. (Detail on this part over here on the ubuntu forums if interested)

Now many google sites simply show the loading error for ever and never recover. Some URLS can kill the browser completely. For example, this one from the Mozilla website: https://support.mozilla.org/en-US/kb/websites-show-spinning-wheel-never-finish-load The error message is attached.

I am happy to perform more tests and provide more diagnostic if it will help. That same URL works fine from the chromium browser on the same desktop systems,as does every other site I've had issues with.

System details: Ubuntu 23.04 64 bit Firefox 113.0.2 Intel_R_ Client Systems NUC7i7BNH (Intel® Core™ i7-7567U) Intel® Iris® Plus Graphics 650 (Kaby Lake GT3e) (KBL GT3) Gnome 44.0 Wayland WS

I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

Games on PCH.com are not loading since I downloaded the last update about two days ago. Help me by showing me how to delete it or tell me how to fix this please.

Hello, I've been having an issue with gmail in my unified inbox where anything that I do with emails doesn't update unless I click on another folder and back to my inbox. Like if I delete an email, it looks like the last one on the list disappears until I click another folder and back, then the one I deleted will be gone and the other one still there. It also happens if I move an email to another folder. I have two other hotmail accounts that still work like they should, just email.

Firefox uses around 1 to 2GB of RAM and around 25% of the CPU with just around 10 tabs open along with a YouTube video. A chromium based browser on the same system and the same tabs open uses around 400MB of RAM and around 10% of the CPU. Safari with the same tabs is even more efficient

I have tested this with safe mode, on another system with the same hardware but couldn't find what's causing the problem. I have uninstalled all dynamic themes as well.

Firefox does not use this kind of resources on windows or linux but uses something more close to chromium numbers (tested on a desktop PC, AMD Ryzen 3 3200G)

While I do not expect Safari levels of optimization, this problem only arising on Apple Silicon Macs is a problem worth solving. This is the only thing that's keeping me from using firefox as a daily driver and supporting the open web.

When I am watching a youtube video the video sometimes freeze but the audio continues to play, I tried clearing the cache but that doesn't fix the. Please tell me how to fix this problem

Thunderbird (currently 102.10.0) became extremely slow at reading emails when I went from 91.13.1 to 102, I'm not sure of the full version but I believe it was 102.3.0 . TB no longer correctly reports whether or not I have emails waiting when I first log in. The size of the emails doesn't appear to be relevant. It may be as little as just a couple of lines of type or it may include attachments. The length of time to download is about the same at anywhere from 20 seconds to 1+ minutes. When I track it on the task manager, of the 4 images of TB there are always 2 images of TB seemingly active at the same time when I Get Message. One image is very large while the other is much smaller relatively. All of this with both the Scam Detection and Antivirus turned off. After reading a number of the entries on the forum, I performed some of the steps suggested. Here is a synopsis of what I did and what I saw.

Put TB in SAFE mode. Sent a message. Did Get Message(GM). Task manager showed only one large TB image active, not the usual two mentioned above. Download was the usual long time. Sent a second message and had the same results. Turned off SAFE mode. Did another Send and Get 2 more times. Task manager showed the two images active. Response times were slow. Turned on SAFE mode again and repeated as above. Results were the same - one active image and slow response.

Started Windows 7 Pro in SAFE mode with internet. Started task manager and TB in normal mode. Sent a message. Did Get Message and the mail was downloaded immediately. Sent a second message and had the same result.

Started Windows in normal mode. Turned off email antivirus and smart firewall features in Norton 360. Repeated test scenario as above. The results were the same as I stated in the begining of this submission.

If there is anything else I can add that would help me to get Thunderbird back to normal, please let me know.

While attempting to access a file folder with 977 email messages the file completely disappeared. Rebooted TB but it did not return. Using MS ver. 7 pro. Deleted over 5K emails from various file folders. This has happened several times before but two files returned and two files cannot be found. How do I find these files especially the critical 977 email messages. Thanks, Rick Arlen
