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?

Installed new Linux OS, forgot password to profile when opening firefox, created new password, logged into my Profile which has the correct user picture, but all my passwords and bookmarks are gone. ( I want to cry man..)

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.

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!

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?

Hi,

I added some annotations to a PDF using Okular on CachyOS. When I open the PDF in Chromium’s built-in PDF viewer, the annotations appear in the correct positions, just as they do in Okular. I also checked using a few online PDF viewers, and the annotations display correctly there too.

However, when I open the PDF in Firefox, all the annotations appear in different positions than they do in Okular.

so im pretty sure it uses dpi and because im pretty sure the vpn is not encrypted it doesnt work maybe add an option to encrypt/bypass blockers such as these (xvpn looks have a look at how that works(pretty sure xvpn steals your passwords so if u fix this i love you))
