The recommended methods, changing to this in the registry :

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\Certificates] "ImportEnterpriseRoots"=dword:00000000

Reverts back to 00000001

Put this policies.json and did nothing: {

 "policies": {
   "Certificates": {
     "ImportEnterpriseRoots": false
   }
 }

} What am I missing or what's changed?

My specific need at the moment is to add another search engine option in about:preferences#search

Thanks.

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

Hi! I'm trying to set Thunderbird as the operating system default under Win 11. I tried to follow Mozilla's instructions: 1. Open the Settings application by pressing and releasing the Windows Start button, then clicking the gear icon. 2. Click the Apps icon, then click Default Apps in the list. 3. Click the icon under the heading Email to show your choices. 4. Select Thunderbird. The trouble is that at n. 3 there is no choice. There is only 'OutlookAccounts' and this item cannot be deleted or replaced. Can you help? All the best, Robifiori

I'm currently on Firefox Nightly on desktop running the latest version. I wanted to know how to turn my Firefox Tools icons back from just having icons at the bottom to the list of icons with their names like before. I've attached both images, one from another computer running an older version of nightly which is what I want to return back to.

If there isn't a way to change it back, I would like to suggest this as an option to be able to easily turn back to a list type.

bold text I did something that made my FoxFire window cover 1/3 of the total window on my MacBook Air. It used to cover everything except the bottom and top bar. How do I get it back?

As the title says, firefox keeps reenabling delete browser history when firefox closes on its own. After an update yesterday it seems to have reenabled it AGAIN. Back in May near the end of it it also reenabled itself and deleted years of firefox history out of nowhere and I never knew it did so until the next morning when I went to go to a specific part of a site I frequent only to find when typing out the keywords to it, didn't exist.

Found it reenabled itself on its own. Disabled that, and got some semblance of my history remembered again into the system. Made a backup copy of history to some degree into a copy of the places.sqlite file. Yesterday firefox updated again. Closed it last night when i shut off my PC to go to bed and this morning when I opened firefox, I find all my history is gone AGAIN. See delete history when firefox closes is reenabled once more on its own without my permission barely 3 weeks later. I then try to input the backup places.sqlite i made a few weeks ago as well and it gets overwritten by an empty one after I input it back in and open firefox.

I've tried searching for why and how this keeps happening. But every time you search anything on this topic its nothing BUT how to ENABLE the setting, nothing about it auto reenabling and how to stop it or what could be causing it. Web searches are legitimately 0% useful because its just nothing but one sided search results repeating the same thing ad nauseam.

Hi. How do i change my settings so that I don't need to press "download complete message"? Seems like a 1990s choice to default to not load messages directly if you ask me.

I noticed on both Android 15 and 16 that the FF app shows 'Ask Bing' (see attachment) when you invoke the copy/select all/search etc. popup. .

I have not found a way to remove this. Any ideas?

I'm using Firefox-bin on Gentoo, wayland, and for a long time with all updates on my main firefox profile smooth scrolling can not be disabled: Both UI settings called "Use smooth scrolling" and manually setting general.smoothScroll on false - does nothing. Setting general.smoothScroll.mouseWheel on false actually disables smooth scrolling for mouse wheel, but smooth scrolling still happens on keyboard scrolling (holding up or down arrows).

On same browser I have two different profiles: On one of them smooth scrolling were disabled long ago On another one I successfully disabled smooth scrolling this day (it's some default one that I haven't used)

There are no extensions that could override this and I tried disabling them and rebooting and trying again too. I haven't touched any other scrolling relating options except enabled "autoscroll" and tried disabling apz.gtk.kinetic_scroll.enabled but it made no difference.

I found only few entries that describes same thing from long ago but they seem to not be applicable to this one. This bug is only mildly annoying because I rarely use keyboard scrolling and general.smoothScroll.mouseWheel = false already solved half of issue but I'm worried a little if something is wrong

I don't like threaded conversations view. I turned it off so my inbox doesn't show it any more, but search results do and I find it impossible to find what I need. Is it possible to turn off ALL of those threading features across the entire program? Thanks

Bonjour / Good day,

The e-mail display notification at the bottom-right of the screen was displayed with my r.-pi4 but not anymore with my r.-pi5; can someone help please?

Thank you for your time and I am available for any clarification.

Regards,

I have a 4k monitor, with Windows scaling set to 150% to make text readable. On firefox the text is still very small - I think it is not scaling according to the monitor setting. I also think this issue only started recently?

All other apps show the text at the scaled size on that monitor. Firefox seems to be the odd one out. Screenshot attached with another app to show the difference.

I hope that I chose the right Category. Issues as per Title. They have all disappeared when I signed back in. Syncing appears ok. When I open the Extensions Folder near Profiles, it's empty? Have a FF 32 digit Recovery Key. Good for anything?

Usually I login to my account on a public PC and when I finish my work, I log out and erase all data. From some build it doesn't fully erase the history, meaning it reloads my tabs when another person opens Firefox.
