Suddenly I can't attach images (or anything) to outgoing emails. I do this a lot and it worked fine all day yesterday, then stopped in the evening. When I click the Attach button, nothing happens. I've deleted 1000s of emails and compacted the folders, nada. My Thunderbird is up to date v153.4 on Win 10. Any ideas? Thanks, Andy.

Been happening for almost 2 months now and getting more frequent. What happens is FF opens normally , but reacts sluggishly. Many instances of "not responding". When I close the program , it takes several minutes to close. In Task Manager , it shows disk usage at 100% , CPU at as high as 50% , and memory at 4 gigs prior to crashing. This is on a Windows 11 Pro system with the latest updates and the latest FF.

Below are the 5 latest crash reports:

I just updated to Firefox Version 157.0 and set up vertical tabs on the left side and love it. I also have "Hide tabs and sidebar" clicked which I assumed would hike the sidebar until I moved my cursor to the left. That doesn't happen. The icons for the various tabs remain displayed. Am I wrong to assume that this setting means the sidebar will be hidden until the cursor is moved to this area?

Thanks for your input.

Suddenly Start Page has become my default browser when I open Firefox. Duck Duck Go has always been my default browser. I did not download Start Page. I don't want Start Page. My PC Win 11 is set to use Duck Duck go as the default browser. Why is this happening?

For the pas 2 mouths i am getting random: "Server Not Found.Firefox can’t connect to the server at" It is happening on random sites that i know for sure they are not down... Waiting , closing fire fox and open it again, refresh but after waiting... helps.

I have a completely vanilla install of TB fully up to date as of this writing [it is version = 156.0.1 (aarch64) and I checked for updates], no extensions, no proxy, on a new OSX 27.0 (Golden Gate) computer and even when idling it is using substantial resources. The only thing even remotely non-basic is their is the Proton Mail Bridge to connect to Proton Mail for one of the linked email accounts, but that is its own little program with its own threads and takes almost no system resources even when sending or receiving mail (which is not happening currently.) Look at the attached screen shot.

In the screen shot I have left Thunderbird to idle for about an hour. No new mail in that time and other then clicking on or off the window to bring it to the fore I have not interacted with the program at all myself. Meanwhile Thunderbird and its Thunderbird GPU Helper are using substantial amounts of the CPU and GPU, have a combine total of 86 threads (more then any two other things running except the kernal tasks) and are hogging ram (not depicted).

Meanwhile among a few other applications (Apple Music, OfficeLibre, etc...) I also have Brave Browser opened in the background running with two windows and a total of 8 tabs wherein Brave is actively downloading GB of data from MEGA as well as performing other admittedly lighter tasks. Even when doing all this, Brave barely registers on computer resources compared to Thunderbird and Thunderbird GPU Helper when they are just idling.

Is this all proton mail's fault with the Proton Mail Bridge? If not is there anything I can do to quell the hunger for computer resources of this voracious beast of an email client that is TB and uses resources as if it were a video game even when idling?

I routinely check out several local news outlets' websites and for the last 2-3 weeks, since a Firefox update (using FF 156.0.1 (64-bit) on Win11, v25H2, Build 26200.9550) I keep getting a Norton popup box saying "we prevented your connection to <x> because it is a malicious website", where 'X' is either littlestastronaut.com, or something like planted.com (screenshots of Norton popup windows doesn't work). This doesn't happen with any of the other couple dozen websites I visit, just 2 out of the maybe 5 or 6 different news websites I look at. Odd thing is I look up either of these two 'dangerous' websites and they either don't exist or they are some school related website. That popup comes after I have to select either "continue without ads" or go to the FF address bar and disable the ad-blocking for that site, so I'm thinking that there's maybe something in FF that is causing this? It happens on both of these sites whether I check "continue without ads" or disable the FF ad-blocker which doesn't make sense that that 'malicious site' is contained within an ad on the news site because on one I don't disable ads so it shouldn't even come through but still Norton catches it??? Yes, A-I will one day rule the world....ya-right.

Windows 11, Dell laptop, Thunderbird Meadow 153.4.0, yahoo mail configured as pop3 (i like to keep messages on my laptop). I was having trouble with mail getting "stuck" on downloading the past week or two, sporadically. It would load maybe 13 of 90, or 4 of 64, or whatever, then I'd get a "Connection to server timed out" message. I went online to the yahoo mail site to look for some offensive email that was trying to load and delete it; deleted about 50 of the messages that would've been sent to Thunderbird, then tried again. Did this a few times. Today it started where it wouldn't even load 1 of 34, or 1 of 60, or 1 of 96 as the day went on, would just time out on trying to load the first one.

Tried changing to IMAP temporarily, didn't help. Switched back. Didn't help. (Restarting each time I'd change this). Finally resorted to deleting the account (and all of my folders and filters! argghhh!) and re-adding it. Let Thunderbird automatically configure it for pop3. I did change the setting to not have it delete the messages on the yahoo mail server once loaded into Thunderbird.

Seemed to help, and it immediately tried to download the 3800+ messages that I've saved on the yahoo mail server. Only got to 1900, then stopped and timed out.

When I ask it to download new messages, it's back to the same thing - tries loading 1 of now 2007 or something, and can't get past 1. Times out.

Notice the version number above; it was much older, and I've since updated it 4 times to bring it up to where it is now where no additional updates are available at the moment. So as much as I'd like to blame it on an update, I hadn't had any automatic updates for a long time, so it wasn't that, and getting the updates now hasn't helped either.

Any suggestions?
