Hi,

At my work, we use Windows AppLocker to allow only trusted code to be executed. Firefox works great in this environment, but I do have a request.

We were regularly getting notices of untrusted code being attempted from the "%windir%\temp\NS?????.tmp\" folder, which was a mystery to us for a long time. We finally tracked the cause back to "C:\Program Files\Mozilla Firefox\uninstall\helper.exe", which extracts DLLs (e.g. system.dll, shelllink.dll, userinfo.dll and accesscontrol.dll). It's my pleasure to report that the extracted DLLs ARE signed (btw, thank you so much for that!!). However, I had an embarrassingly hard time getting to this point since the code is code only exists temporarily, and I sadly never had the thought that NS might mean Netscape.

Incase there are others in my situation, I was wondering you'd like to prepend the .tmp folder name to include moz- or Mozilla?

I think there may be others in my situation, since our instance that followed the best practice of exempting all DLLs in Program Files from the exclusion policy, and since Firefox keeps all DLLs in Program Files, these were the only Firefox DLLs being checked.

Thank you for 30 years of a great product!

Hello, I recently bought a MacBook Air 2024 with G3 chip (Sonoma 14.6.1) and used Time Machine to transfer all the data from my previous Apple MacBook Air from 2015 (Mojave 10.14.6) to the new computer. This also transferred my Thunderbird profile folder. It has the extension .default and an 8-digit combination of letters and numbers in front of it. Since the old version of Thunderbird no longer ran on Sonoma, I installed Thunderbird 115.15.0 and then opened Thunderbird on the new MacBook Air. Since then, Thunderbird has been taking an extremely long time to open (much longer than on the old MacBook Air with Mojave. Yesterday I updated to 128.2.0esr, which didn't help either. I deleted a deactivated extension in the add-ons, so that there are now no extensions, only a few dictionaries that I deleted as a test, which also did not bring any improvement. Switching off the hardware acceleration, clearing the cache and changing the themes did not improve the situation either. With the themes, I can only switch between dark, light and system theme - automatically. I checked and made sure that Thunderbird actually loads the .default profile folder from my old computer as the active profile. However, Thunderbird has also automatically set up a second profile with the extension .default-release. Could this be causing the problem? My active profile folder has a size of 15.21 GB and the new .deault-release profile folder has 18.6 MB. Both profile folders are located in Library/Thunderbird/Profiles I am quite desperate and hope that someone can help me. Thank you very much!

I have been assiduously marking all the junk and non-junk items coming into my junk mailbox for over a month. The situation was better, the volume of junk mail was decreasing by half every two weeks. Now it is rising again to pre-thunderbird levels. Has something happened to the junk mail filter to stop it from working? Why does it take so long to identify junk. The same words keep appearing: debt, lawn, lawyer, cancer, zantac, loans, credit, glasses, frames, windows, insurance, fitness. If I can spot these why can't a the filter. Honestly, this spammer is driving me nuts. My account is with hotmail.com.

I get PR_END_OF_FILE_ERROR when trying to load certain websites. I don't use any proxy or VPN, I tried disabling DoH. Also sometimes i get 403 forbidden cloudflare.

Right now there is an annoying hybrid Reopen Closed Window or Tab feature on the Ctrl+Shift+T hotkey. But Reopen Closed Window already had the Ctrl+Shift+N hotkey, even prior to this change. I can't find anywhere to change this behavior.

Why is Firefox Browser no longer an acceptable browser to access some on-line accounts? Business entities are no longer recognizing Firefox. When utilizing another browser connectivity is no issue.

Hi!

I've been a Firefox user ever since I've had an internet connection (probably around 2008). Whenever I would do a clean Windows installation every 1 or 2 years, I remember I would have my passwords, history, and extensions synced. Today I performed a clean reinstall again after maybe 2 years and I don't have any of my old history, passwords, extensions.

I'm a bit desperate, I have really important stuff saved over the years. I use Tree Style Tabs and I've customized my browser client to fit my needs and it was perfect, but I seem to have lost everything and I don't know what happened. It didn't even cross my mind something like this would happen.

Is there anything I can do? I have old emails from 2018 and 2021 from Firefox Accounts which show I used the same email.

Today when I tried to log-in into Firefox Accounts from inside the browser (button at the top right corner) it seemed that none of my passwords worked, so I clicked the "Forgot email" password and set-up a better one, but once logged in there was no sync with the old data I had. Then I thought maybe I had the wrong account so I logged in with my Google/Gmail account but there was nothing there as well.

Is there something I can do? I really need my old history, passwords, extensions, etc. Especially now as I'm graduating from University and I have important events coming up.

And no, I don't have any local profiles any more since I did a full, clean reinstall on my primary SSD. But I remember I've never used local profiles, everything would sync up again once I logged in. Maybe forgetting and resetting my password logged out my previous session and I lost it forever?

I hope you can help me sort this out.

Thank you for your time!

As the title says, when I enable the "Digitally sign" option for OpenPGP in a new mail, I get "Sending of the message failed" when trying to send, but if I disable only this option, then the message sends successfully.

That is the case whether I encrypt or not the message.

The versions of Thunderbird I tried where: 115.14.0 and 128.1.1esr.

When previewing an image that was uploaded to a Google Calendar Event, I get an error "Couldn't preview file. There was a problem displaying this image." I've spoken to Google support and they suggested I reach out as when I try in Chrome, it works. Firefox is my preferred browser so I would love if I didn't have to switch to Chrome.

Troubleshooting Done: - Verified Firefox is up to date (130.0 64 bit) - Cleared cache and cookies, closed browser, reopened - Tried in 'Troubleshoot Mode' - Ad Blocker turned off - Uploaded test .png and .jpeg to see if it was a file extension issue - Uploaded smaller versions of images to see if it was a size issue - No issues when doing same steps in Chrome browser

I have used Firefox for years to use application Availity. All of a sudden cannot open on FireFox but open it in Chrome. I sign in to Availity and 'acts' like going to load but goes immediatley to the sign out screen. Reached out to Availity said to clear Cache...I did restarted and same issue.

Hi,

I've been wanting to switch from Chrome to Firefox for the longest time, but I can't do it since surround audio doesn't seem to be supported natively in Firefox. I'm using a Logitech G733, with "Surround Audio" activated in GHub, and on Chromium based browsers, it works, I hear it when watching Youtube videos, Twitch streams..., but on Firefox, it defaults to stereo audio. I haven't been able to find any settings related to audio in Firefox, nor in the concerned websites. Is it a known issue ?

Please, explain me (with pictures) what should I do, to be able to read my received emails in Tb

I run Thunderbird on a PC, and, to free up space on Drive C:, I have moved the contents of the folder Thunderbird in Appdata to Drive D:. I then changed my Server Settings, in Thunderbird, from C: to D:, and note that any new mail is indeed now appearing there along with those already transferred. This move could save me a valuable 6 gig of space, and more in the future, however, I am unable to remove that original Thunderbird folder entirely, notably I am unable to remove the contents of the Profiles folder, as it is still linked to the application. Notably with cookies.sqlite, cookies.sqlite-shm, store.json, mozlz4, aborted-session-ping and many others, which I note some have continued to be updated. I have been unable to find any other settings in Thunderbird referring to Drive C:, other than those in Server Settings.

I could presume that if I installed another version of Thunderbird on Drive D: and maybe moved those existing contents of the Thunderbird folder on C: onto Drive D:, and made those numerous settings changes to the App it could work. But I ask is there an easier way to complete this move? How can I complete this transition of Thunderbird from Drive C: to Drive D:?
