Previous to version 151.0.1, when I pressed ctrl-L, Firefox focused the URL bar and I was able to edit the URL. Now, on 151.0.1, pressing ctrl-L clears the URL and a dropdown for the search engine appears in the left of the URL bar (see attached screenshot). I have verified this on a new, blank profile. Is there a way to restore the old behavior?

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

  • Settings > General > Startup > Open previous windows and tabs > TRUE (checked)

macos 26.5 (25F71) Tahoe:

  • Settings > Desktop and Dock > Mission Control:
  • ---> Automatically rearrange Spaces based on most recent use: FALSE
  • ---> ...switch to a Space with open windows for that application: TRUE
  • ---> Group windows by application: TRUE
  • ---> Displays have separate Spaces: TRUE
  • Dock > Firefox application icon > [Right Click] > Options > Assign To > This Desktop (i.e., Desktop 3)
  • Apple Menu > Shutdown > Reopen windows when logging in: FALSE

Whenever i send a message , it is saved to the 'inbox' previously it would be saved "sent mail". I have verified that TB is configured to save to sent mail but the msg is saved anyway to inbox.

Can some one explain how to get back to saving sent messages to sent mail folder.

In all honesty I find it frustrating to keep moving msgs manually.

Can't get filters to function

I'm trying to transition from Eudora to T'bird. I've got both installed on my Win11 laptop. I've used Eudora 25+ years, i have about 4 or 500 filters set up. I can't get even one filter to work on T'bird, so my Inbox now contains a near-useless jumble of over 2000 messages. Gotta get past this to keep using T'bird. E.G. I subscribe to an email forum called Baen's Bar. It accounts for 80% of my inbound traffic. So I set up this single filter:

Apply when: Manually and New email Match all of: From Contains baen Subject contains baen To contains baen

Actions: Move message to: Baen Bar on green@xplornet.com' (i created this folder and see it below "Inbox") (AFAIK these criteria should capture every relevant email) (Question #1: is matching content a case-sensitive test?)

(Aside: when typing this query, i tried to make the actual dialog italic for clarity. I highlighted some text and hit the "i" above the dialog box, all it did was enclose the highlighted text with quotes - really? so Question #2 - italics not working?)

Anyway what happens is, no apparent filtering when getting new mail, and in the "Message Filters" dialog box, when i select the one and only filter, and make sure "Enabled" is checked, and click on "Run Now", also nothing happens. Ok, i say "nothing", but when i look in the "Baen Bar" folder, there are three (3) messages containing the word "baen". Three out of the 2,000 such messages cluttering my inbox. I could understand "none", i could understand "2,000", but "3"? WTF??? I tried it multiple times, not sure which attempt even got those 3. Solutions gratefully accepted.

Question #3 I noticed a reference to "Importing filters from Eudora". I DO NOT want the **content** of Eudora's hundreds of mailboxes to be imported - it's probably over 8 Gb. I'm fine leaving that content archived with Eudora. Is there a way to import the filter list and folder list from Eudora without importing the contents?

Question #4 Where is T'bird storing my email? Most of my cyber-world is on an external HDD. I love about Eudora that it's fully portable. I can literally unplug my external HDD from my Win11 laptop and plug it into your laptop, rename the drive to J: and just run Eudora. Can i do that with T'bird?

What in the world are you thinking!?!

Firefox fails to obey OS-defined DNS and instead overrides this to use …….Cloudflare? Are you nuts?

Whoever told you Cloudflare is private or secure failed to educate you on Surveillance Capitalism.

For the love of all that is good in this world, rekey Firefox to allow user-defined DNS- whether that is through DHCP, manual config or a management profile.

So I have a list of folders some of which are the default folders some are custom created.

When I try to re-order these it is very hit or miss: I select a folder, drag it to where I want it to go, wait for the blue placement line to appear and it may or may not re-locate. Or I simply can't move the folder I want to move and so I move folders around it in order to achieve the layout I want.

It is as if success depends on whether Thunderbird is in the mood for a particular move to happen and I find it really frustrating. It should or shouldn't work, it shouldn't be that it works sometimes.

What is going on with this?

When clicking "play" to test the sound, there is no sound. Also, if "use the following sound file" is checked, there is no sound when "play" is clicked. (I have tried various .wav and .mp3 files.) I have installed pipewire-alsa, but that didn't help. Any ideas?

I started setting up Thunderbird on May 8, after I got my new windows 11 computer. I added 6 of my most important email accounts (different providers). Today, I went through settings to make things better (I thought). Immediately after, all my email accounts (both current & previous messages started printing in plain text only. I tried to fix by going to view, message body as...simple text, restart, then back to original HTML. Then, restart again. All this to no avail. I am sure it is a setting because until today, all were in HTML.

When using the Android version of Firefox, enabling "Always request desktop site" in settings works as expected when directly searching for a website via the address bar, resulting in the requested desktop site. However, when navigating to a new page via this method (such as clicking search engine results), it returns the mobile site. The browser menu bar still displays that the desktop site is enabled, and clicking the button still refreshes the page, but the result remains unchanged, still showing the mobile version. The "Desktop site" button status also remains unchanged. Everything works normal only after completely closing the app, but the issue persists upon subsequent navigation. It can be confirmed through the User Agent detection tool that the issue is with the User Agent.

I have had to buy a new desktop to get Windows 11.

I have installed Thunderbird, which I have used for many years, on the new computer. This version threads the incoming emails. I really hate my emails being threaded, it completely confuses me and prevents me doing what I have to do. I have not had this problem ever before. I have searched all the settings and not found any that will stop threading. Because the effect of threading seem permanent I now need all my emails reloaded to get rid of the effects threading.

I uninstalled Thunderbird and reinstalled hoping I could get a fresh start. I got the same old problem back again.

How can I get a version of Thunderbird that does not thread any of my emails ever?

And can I get all my existing emails re loaded?

I am trying to disable the text segmentation behavior in latest Firefox(v151), but I have encountered an issue where changing the preference in [about:config] does not seem to have any effect.

Details:

   Target Preference:  intl.icu4x.segmenter.enabled
   Current Setting:       false
   Problem: 
   Even after setting this to false (and restarting the browser), the text segmentation behavior (such as word selection logic) remains unchanged and appears to still be using the ICU4X engine.
   Reference:
   https://support.mozilla.org/en-US/questions/1440483#answer-1638092


I would like to know:

  1.  Has this preference been deprecated or hardcoded to true in recent versions of Firefox?
   2. Is there any other way to disable the ICU4X-based segmenter or revert to the previous segmentation logic?
   3. If this is a known change, is there an alternative preference to adjust how word selection handles specific languages (e.g., Japanese)?

I am using the latest version of Firefox. Any insights or workarounds would be greatly appreciated. Thank you in advance for your help!
