I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

Hi:

I'm a longtime ubuntu (lubuntu, actually) user, and upgrading LTS versions every 2 years has been pretty easy til now: all I had to do was copy my .thunderbird folder to the home directory of the new system.

When I do that now for the pre-release version of lubuntu 24.04,, the new Thunderbird requires setting up the new profile from scratch, which is a pain, since I use T-bird for multiple accounts.

Is there an easier way of migrating my emails from my old profile to the new system?

Thanks!

Bill

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

ive built a new pc and have a flashing program popup every 10min. upon assistance from a really good pc guy, we've found its a firefox default browser agent with a long code.

its not listed in my scheduled tasks, eyt runs every 10min. only thing close to firefox would be thrunderbird, but iirc, mozilla and thunderbird are not longer the same company. either way. i need this thing to stop running every 10min.

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

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 ??

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

Hello and Good Morning!

I need to transfer messages from one computer to another. I follow your instructions - export to .zip, file smaller than 2gb. On the second computer, I import the .zip file, the import seems to be successful, then I restart the program and I don't see the imported data anywhere (only Local Folders is created, but it is empty).

Could you please help me? Will be very, very helpful ;)

Somebody is using my name on your website with a different email address and it is not me. I need your help. My email address is Bobbiledvina85@icloud.com I don’t know who this is

Hello, Firefox just released the newest version on PC and advertised it with a speedtest: https://browserbench.org/Speedometer3.0/ I made that test and got a score of 7.03 I made that test on Opera mobile (My phone got locked while the speedtest was running, so this may had impact) and got a score of poorly 2.14 BUT on Mozilla mobile which I can confirm feels SLOW is the speed score: 1.70 And now lesser is not = better. I like that you can arrange tabs, I like that you can use addons, but I miss a scrollbar, I miss side LOADING/OPENING speed. Many many people love Firefox on PC, but why is it that slow on mobile? And why can I not get a button to scroll fast up and down? I have to install a addon which I need to access everytime to click "scroll to top/bottom". That isn't handy!

I really wish, the developers would share some love, because I LOVE firefox, but this is just not useable :( I mean come on, a scrollbar! Give it me! And SPEED. And no my Samsung Galaxy S10+ with 8GB ram isn't too slow.

I haven't been able to login with MFA on my uni website and also make purchases using credit cards on commercial sites.

I have tried Troubleshooting mode and the problem persists. Switching to Opera browser showed normal functionality.

Firefox 125.0.3 (64-bit) on macOS 14.4

I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

I'm having trouble using my bank's website. Sometimes I can't log on (error messages) or I can log on and can't use certain features. The bank is Regions. The site works with other browsers. Is there some setting on the latest Firefox that needs to be adjusted? The articles I've read don't help. Thanks.

i had some problems with windows services and firewall and network. i installed the tool from tweaking.com( i don't know if it is legit or scam or virus or anything. would appreciate clarification.) after i repaired windows with it some of my apps including firefox did not start and were corrupted. after that i wanted to reinstall firefox and used the helper.exe from the uninstall folder in mozilla firefox folder in drive C. it restarted firefox and all my tabs were gone. i accessed the jason files (recovery,restore,...) and none of them had my tabs. i signed in to my account and all my history and bookmarks are still here but about 100 tabs were lost. i really need those tabs and i am in desperate need for help. thanks ( in no parts of system repair or other actions i have not created a back up and do not have that back up or system restore files)

Hello; I installed a new web page. While the page opens properly in browsers such as Safari and Chrome, in Firefox it constantly displays 403 forbidden Access to this resource on the server is denied! gives an error. I deleted the caches. I did flush DNS. I even reset firefox. I tried everything but the page still gives an error. There is only a dry WordPress content. How can I get rid of this error? Thanks.

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.
