Thunderbird 125.0 (64 bit)

When on the Princess Cruise web site looking at various cruise options, the Firefox browser will not let me open the list of excursions for the ports on the cruise that we were looking to book, but I can see them when using Google Chrome. Why won't Foxfire allow me to view the excursions - it use to allow me to see them.

This is what the message says. It got hung up after the DONATE message posted. i donated, but it didn't free it up.

"Unable to open the folder Inbox on robert@perless.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again."

Apple says it is a TB problem, not an Apple problem. Somebody please help.

I am running this computer for my late husband who left us in September after he fell off a 25' ladder at the age of 85. It still has all the information from his art. He was a sculptor who made large kinetic pieces.

Please help. Ellen Perless ellen@perless.com

Good day Mozilla vols! Has anyone else heard of, or developed an issue recently where TB will not delete multiple emails when selected? Previously, when I selected multiple emails for deletion and clicked "delete selected messages", TB would hang for a bit (while processing), but then all my selected messages would be deleted from both TB and my mail provider.

With timing conspicuously aligning to the 115.10.2 update, the multiple email delete functionality has broken. Now, when I highlight multiple emails to delete, instead of deleting them, TB marks them all as read, and only deletes a single email (the oldest email in the group I selected).

I saw one other question about this, but it was marked "archived" without an answer. Any thoughts/suggestions would be greatly appreciated.

We are using a website designed for Firefox, and when we use the "print" function within the website tool bar, on one of our PCs, it always defaults to a print preview which states "Printing from Win32 Application - Print". We have "print.always_print_silent" set to true, on this and all of the other PCs using the website, but only this PC has the issue. We can't figure out what is making it pop up the print preview.

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

Since upgrading to version 115.8.1 I get unable to write email to mailbox . I have three email addresses in my profile. All are POP. One (from yahoo) always hangs and the other two fail intermittently. OS is Windows 10 64-bit at 22H2 level It doesn't matter if Zonealarm is turned on or off. I have over 300GB of free space on disk.

Full error message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

when I log into wetransfer.com the file transfer box is greyed out and I cant use. It works in Microsoft edge.

I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

The same happens in troubleshoot mode. I also tried reinstalling an older version but the same thing happens. Help me figure out what's wrong so I can read emails. :(

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

I notice this subject has been mentioned prior, but I cannot find a resolve. Been using Thunderbird for a long time without issues, but last week it stopped sending and receiving emails through the Skymesh internet provider. Still sends & receives Hotmail/Gmail/Yahoo, but will not connect to any Skymesh accounts. Have reinstalled/updated, but no change. SMTP timeout and if I change settings I get the 10060 error. Could not even connect to their Webmail page either. If I turn VPN on, then I can access their Webmail page. Rang Skymesh, they poked around and said it was all this end and with Thunderbird. Seems an IP number change via VPN with Opera resolved the Webmail page access, but I cannot do that thru Thunderbird. Running Win 7. Anyone ??

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

I attempt to open Thunderbird in an iMac but the computer says it is already open and only one can be open at a time. I can not find a Thunderbird open on the computer.

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Thunderbird 115.10.1

If I attempt to print many emails at one time (by selecting a group of them from a mailbox), Thunderbird sometimes gets lost in the middle of the job and chooses a random email (not from the selected group or even the same mailbox) and combines many others into the same email and tries to print (leading to a single email showing 200+ pages for that one entry in the print queue and actually composed of many emails put together, but not the ones I selected).

Does not happen if I only select a few emails at a time.

Sounds like an indexing issue with the file that holds all the emails. Perhaps something gets corrupted?

Any suggestions?
