wie bekomme ich dieses flieder wieder aus der darstellung. seit dem letzten update wird der Hintergrund in Flieder dargestellt. Es mag ja Leute geben denen das gefällt, aber mir sagt das überhaupt nicht zu.

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..)

I have had Refdesk.com as my home page for years. Firefox has now decided that it cannot find that site. Please help

Almost every time I launch Firefox, I'm interrupted by another update. Instead of getting straight to work, I have to deal with update downloads, installation prompts, or restart requests.

There is no reasonable way to disable this behavior. Even selecting "Check for updates, but let you choose to install them" doesn't help, because Firefox still interrupts me with update notifications.

Why can't users simply check for and install updates manually, without constant interruptions?

For a browser with such a small market share, Firefox is remarkably aggressive about imposing this intrusive UX on its users.

Please provide an option to completely disable automatic update checks and notifications. Let users decide when to update their own software.

There doesn't seem to be an "Other " or "Additional Options" category, so if Settings isn't in the correct category, please tell me where to post this. TIA

I want to be able to create multiple default 'pinned" tabs that will appear every time I open up a new window. Is that possible? If so, how? Again, TIA

I dont want this profile feature at all it's a complete and total nuisance so I deleted the only profile it had for me but now everything but my bookmarks are gone and I need my settings restored. How do I completely disable this nuisance so I never have to see this annoying color bar in my application menu again? All my settings are destroyed now.

Before the last update, I’m using version 157.0 now, it was possible to simply move a complete Firefox tab using drag-and-drop. I frequently used this feature in a multi-monitor setup. While it is still possible via a right-click and the "Move Tab" option, that takes more effort than simply clicking and dragging.

Is that just switched off and hidden in some options, and really no longer possible?

Thank you,

My manage exceptions list is now being cleared out and clearing out all the cookies and site data with it when I close my browser with the "Clear cookies and site data every time you close Firefox" checked off.

It should only be clearing out cookies and site data for everything outside of the allowed things in the managed list.

Hello everyone,

I'm looking for ways to troubleshoot streaming video issues in Firefox. Sometimes video playback can be affected by browser settings, the internet connection, or device performance.

What steps should I follow to identify the cause and improve playback?

I also came across Selvydia while researching IPTV and streaming services. Would browser troubleshooting differ depending on the streaming platform being used?

Thank you for any practical suggestions.

I've been using firefox for a little while- maybe three months now. I'm no expert on any of the config options. I run firefox using the built in VPN that my friend showed me how to enable, and I've been using it since. But now, as of roughly today, whenever I enable the VPN, no websites will load. At all. When I turn it off, they load instantly. But whenever I turn it on, it just gets stuck loading forever and ever, never actually getting anywhere. I tried enabling network.dns.disableIPv6 in the config page, because that's what I saw on a mozilla support page- nothing. Didn't do anything. The browser.ipprotection.enabled is still on, and I didn't change anything in settings. There was a firefox update very recently, but everything still worked with the VPN on. I just updated my computer, but I don't think that's it either because it wasn't loading things earlier today either. Not sure how to fix this. Please help?

Hi Mozilla team & community,

I am facing a persistent video playback issue specifically in Firefox (latest build on Windows 11), while the exact same stream plays flawlessly on Google Chrome and VLC media player.

When attempting to stream high-definition HLS live content from my media portal site (https://bidarn.com), the video stalls and buffers every 10–15 seconds. Upon inspecting the Firefox Web Developer Console (Network tab), I notice frequent `NS_ERROR_NET_TIMEOUT` errors during the loading of .ts media chunks, along with occasional CORS flags during concurrent HTTP requests.

I have already completed the following standard troubleshooting steps: 1. Disabled Enhanced Tracking Protection for the domain. 2. Started Firefox in Troubleshoot Mode (Safe Mode) with all extensions turned off. 3. Cleared all cookies, site data, and browser cache. 4. Tested with hardware acceleration toggled ON/OFF.

Unfortunately, the segment fetching latency remains high in Firefox.

Are there specific parameters in `about:config` (such as adjusting `network.http.max-persistent-connections-per-server` or expanding `media.cache_size`) that can optimize how Firefox handles parallel HLS segment fetching?

Any technical guidance or network config recommendations would be greatly appreciated.
