Does FF have a maximum number of windows / tabs that can be open at one time? I use 12 workspaces each with multiple windows / tabs in them, roughly guessing ~100 windows and ~8-50 tabs per window

FF randomly hangs / crashes 1-3 times a day for me and has been for some time (over multiple revisions of FF; currently 157.0.1) requiring restarting FF

System: Large workstation, 128G memory, i9-7920x (12c / 24T) Linux, OpenSuSE Leap 15.6 FF source from FF repos, not OpenSuSE

Any settings I need to change to prevent the crashes?

I'm using Thunderbird on Ubuntu 24 and have some messages in some mailboxes that have lost their headers. I'm trying to fix them.

Early (1980's command line mail & mailx) mbox files were pure text with messages delimited by a blank line followed by a line starting with 'From ' (or possibly 'From: '). When I open a Thunderbird mbox file in 'vi' it is 'converted', or so it says. I'm wondering what this 'conversion' is and why it's needed.

Please could someone tell me what the strict rule that delimits messages in a Thunderbird mbox file is, and what is it that 'vi' cannot handle that requires 'conversion'?

Thanks

Hi; I use Firefox on my phone and my laptop both. In my laptop (Lecoo pro 14, Ubuntu 26.04) in a domain range browser gives me security alarm and don't let me get in. This is normal but when I use other browser in my laptop or Firefox on my phone (s25 ultra) there is no problem at all and it works well! I tried all things. run commands like: sudo snap remove --purge firefox | sudo snap install firefox, sudo apt search firefox/mozilla and than reinstall all installed packages and clear all caches on settings. But none of them worked. Thanks for your responsibility and making such great open-source app.

FireFox Browser Crashing from Multiple Windows with Dual Monitors causing memory crashes in gnome.

google chrome used to have a brower extension called "The Great Suspender" to stop these crashes. If firefox can't figure this out I am not going to continue using firefox and go back to chrome.

Hello,

Is there a method to export my emails in EML format instead of Mbox without using third-party software? Are there any settings in the configuration editor that could change the default Mbox format?

Thank you

Greetings,

I am having this issue since Firefox 155.0.1 or a bit earlier (but overall rather recently) and I still encounter it with 156.

When a web page has a web form that performs a POST request without changing the URL, the behavior seems to have changed. Let's assume I have done the following:

1. I navigated to an overview page (GET https://example.com/overview). 2. I clicked on a link to a page with a form (GET https://example.com/formpage). 3. I filled out and submitted the form (POST https://example.com/formpage).

Now, when I click the Back button,

• previously, I was returned to the page with the form (GET https://example.com/formpage)
• now, I am returned to the overview page (GET https://example.com/overview)

Can I somehow return to the previous behavior?

Thanks!

I get your begging for money, you are obviously young, I have donated more money to you already than all my other email providers combined, period, you will allow me to move , remove as much as I want or I can delete you and you lose any future donations, but ticking me off with this we think this is junk crap trying to get more money from me only makes me want to DELETE YOU YOUNG PEOPLE, you act just like your buddy Google, lmk Anthony, or stop the bs

I am using Ubuntu Linux on a desktop PC running Firefox in kiosk mode going to a specific web page - Every time Firefox does an update (since version 147) the kiosk mode stops working. The very latest update, after a reboot, just shows the menu bars and not Firefox going to that specified web page. Has the kiosk code changed since v147 ?

What do I have to do to get help in this Forum? This is the second time I've posted a Question seeking help, and yet again it is being ignored. Do I have join some secret clique or group? If so please tell me?

Due to issues with upgrading from Ubuntu 24.04.1 to 26.04.1, I decided to just start from scratch with a new clean install.

After finalising the install, I copied across my Thunderbird data to the new partition, merging directories as the data copied across. But, somewhere in the transfer I lost about the last two years emails, with only emails up until 12/24 being available.

There are a lot a important emails I need to recover, and I'm guessing they're still on my PC, in the old partition, and I desperately need help to recover them.

After an update (seemingly, I did not run 'sudo pacman -Syu'), the tabs have changed in look and to be frank i find the new layout ugly. How do I turn it back? Attached is a photo of the new tab groups, i couldn't get one of the circular tabs.

To be clear, I am talking about the gaps between UI elements that were present in early mockups as well as in initial versions of Nova before it was enabled by default in 157. I understand they were a controversial design element with many users disliking them for a variety of reasons (preferences, space utilization, ...) but in my view they were really one of the things that made Nova click and I was disappointed when they were axed before the final release.

My question is whether the Firefox team has made a final decision to remove them permanently and completely, or if there is ongoing discussion/work around reintroducing them, perhaps as something that can be enabled or disabled depending on each individual user's preference?

Good morning,

I am requesting assistance for a recent problem I have encountered sending attachments with email messages I am sending. There is no problem with sending the message itself. And have noticed no problems with receiving messages. When I attempt to send an attachment with a message I am sending, a click on the "attach" icon in the upper right-hand corner of the email screen, provides no response. I didn't notice a problem with this function in past weeks.

I appreciate your assistance. Thank you.
