EVERY TIME I CLOSE FF WHEN I REPOPEN IT, I END UP BACK AS IF I JUST INSTALLED IT. ALL MY BOOKMARKS ARE GONE, ALL MY EXTENSIONS ARE GONE, LIKE I JUST INSTALLED IT.

I'VE TRIED UNINSTALLING AND REINSTALLING AND IT STILL DOES IT.

I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

Hi Team, I am trying to build firefox from sources (git) and I need to build it natively for riscv64 architecture board. Can I get any build steps for building firefox like any kind of documentation or any steps.Can I get any suggestions or help regarding to this Thanks in advance Regards, Saiteja

I have noticed that Firefox has been getting too many updates recently...even as much as 2 updates this week alone. Frankly i'm sick of getting the green icons and pop-ups in the upper right corner. Is there a way in about:blank codes to turn off these stealth downloading behaviour and prompt pop-ups to restart the browser and let me just manually do it in settings when i want to but without notifications ?

was Windows 10 Pro, now Windows 11 Pro on replacement laptop (old one is not operational). I can't get my profile into Thunderbird because (presumably) I'd backed it up using my cloud backup service (and forgot that most of the time it's incremental), with the possibility of a straight copy from the old SSD if it's not fried.

How can I at least retrieve the data in there, (and/or convert it to a readable format) i.e. emails, that are in the Mail folder, including Local Folders? Some of that goes back to early 2000's, and some accounts that I no longer have. It's probably better to have most of that out of Thunderbird anyway, since my profile is ~99GB on disk.

Currently I have at least 7 active email accounts, and that fluctuates with .edu addresses. In the profile IMAP Mail folder, there are 20 .com account folders, a few of which are inactive or from changes, and a couple from setting up my main account just to see if that would link up with the associated files in the old profile (not). I can't tell what they all are except for those for which I'd made subfolders under the IMAP Inbox.

So since I don't only have 1-2 accounts, this is a big deal, and having to keep multiple browsers/private tabs open is not easy to work with. I'd even tried the Firefox Containers as a temporary work-around, but I'm having troubles with that.

Any help is appreciated! I can't get anything done, and the new laptop doesn't even have all that I need set up yet.

I getting messages about version update nearly everyday. That is so annoying. Could you please add an option in settings that notifications could be possible switch off ? I am very happy with current version and don't want nothing to update

This problem only occurs in my Hotmail email account at outlook.live.com using Firefox in the last few weeks.

I typed exactly the same including spaces in both Chrome and Firefox. First 2 lines typed in Chrome, saved the draft, last 2 lines typed in Firefox but in Firefox the nonsense occurs. Amazingly the 2 lines typed using Chrome still display well in Firefox. Firefox adds the extra number in the fractions in the space I had typed! How can I get Firefox to work well at outlook.live.com?

This has only happened in the last few weeks, during all those updates. Am on 138.0.4 Are any of these updates buggy?

Hi,

I’m writing you as a very annoyed, frustrated and seriously pissed off user.

I’m a senior lecturer at De Montfort University, Leicester, and have been using Mozilla since 2020/21 on my university account, since I don’t want Google Chrome and Microsoft Edge is user-unfriendly shit. Now, my Mozilla account was registered via DMU (technically set up by the university’s ITMS) to run as my default browser, which opened automatically logged-in and ready to go each time I started the computer. This is how it has worked for the last four years and through many, many updates… until yesterday.

Since the last update on Monday, May 19th, all my access records, settings and bookmarks have been completely wiped off. In fact, it appears that my university-registered account has been wiped in its entirety. Strangely, Mozilla Firefox is still my default browser but only opens with a standard default window. More importantly, I was no longer able to log into my account, as if my account no longer exists… which also means that all my bookmarks and links to important websites within DMU and externally have all disappeared. It will take me at least 1 week (if I focus on nothing else) to find and restore them.

So, how was such a car crash of an update actually possible? Please note that ITMS at DMU is placing the blame and responsibility of this fuckup squarely on you. Furthermore, why was this update actually necessary? Mozilla Firefox was until yesterday a far superior browser in terms of user-friendliness and style compared to Google Chrome, Microsoft Edge or Apple Safari. Now it’s little more than a cheap, equally flawed Microsoft Edge copycat both in style and user-unfriendliness!

But even worse, I now find out that Mozilla like all those "revolutionary, democratizing" tech companies cannot even be bothered to be accessible for contact when in need for support. Anyway, I would like to know how your update could wipe out my account and all the bookmarks just like that, as if they never existed in the first place. And how do I get my my original settings back?

Very disappointing.

Regards,

Markus

Firefox tries to install helper each time I try to open Firefox. It seems to install and then repeats each time I try to open the software. If I cancel it will not open either.

A file called 'Pending Pings' appeared within the folder in which my Firefox installation is located. I last used Firefox on May 14, 2025. I don't know how it appeared as I disabled automatic updates and made it so it would ask me if I wanted an update, so I do not know why it is.
