This issue occurs with Firefox on my system with the following configuration: Fedora version: Fedora Linux 43 (KDE Plasma Desktop Edition) x86_64 Firefox version: 149.0 (64-bit) Firefox installation method: Fedora 43 x86_64 package repository Desktop environment: KDE Plasma 6.6.3 External Firefox sync systems: Mac Mini (macOS Tahoe 26.4), iPhone (iOS 26.4), Gaming Laptop (Windows 11, 26H1). All systems running the latest Firefox version available. System update methods: `dnf upgrade` (Usual), Graphical tool - KDE Discover (Very rare) When the issue occurs: Usually after restarting or booting the system, but this could be a coincidence. Firefox is generally running when its updated through the usual method. Issue walkthrough: I have never experienced any errors or missing bookmarks. My start page is simply set to "https://fedoraproject.org/start/". I don't know if the Fedora provided bookmarks reappear with this issue, as I have never removed any of them. What exactly changed: Home page and new tab page changed from "Firefox Home" to "https://fedoraproject.org/start/". I have seen this happen a few times on my current main desktop setup, call it something like 1-2 times a month. I will try to capture the next time it happens, but will provide my basic information for now. Your Fedora version (including spin/edition, etc.) and architecture: Fedora Linux 43, KDE Desktop Plasma Edition. Details from about this system: Operating System: Fedora Linux 43 KDE Plasma Version: 6.6.3 KDE Frameworks Version: 6.24.0 Qt Version: 6.10.2 Kernel Version: 6.19.10-200.fc43.x86_64 (64-bit) Graphics Platform: Wayland Processors: 32 × AMD RYZEN AI MAX+ 395 w/ Radeon 8060S Memory: 128 GiB of RAM (125.1 GiB usable) Graphics Processor: Radeon 8060S Graphics Manufacturer: Framework Product Name: Desktop (AMD Ryzen AI Max 300 Series) System Version: A6 What Firefox version you use (package, Fedora flatpak, Flathub flatpak), and whether you have multiple installed: Firefox from Fedora packages, currently version 149.0-4.fc43. I do have other firefox alternatives that run on this system. In particular, I have LibreWolf and Tor. I do also use Firefox in docker on specific times, though being Docker, with isolated filesystem folders, and instances I intentionally don't sign in via sync, they should be non-impacting. Any important system customizations or changes such as file system or kernel: None at this time. In the past I was using beta kernels, but at this point, I'm using a mainline kernel. That said, it should be noted that this is a dual boot system primarily I see this issue on. Fedora KDE is the primary OS, but there is a Win11 partition on this system as well. Your desktop environment: per above, KDE plasma, version 6.6.3 Information on all other systems synced with Firefox Sync to the same account, if you use it: I'll be honest, there's a lot. I have a MacBook which I sync (MacOS Tahoe), a Framework 13 laptop dual boot (Linux Mint and Windows, mostly booting Windows), both with packaged firefoxes. Mobile iPhone. How you update your system (graphical tool, `dnf upgrade`, `dnf upgrade --offline`, etc.): depends. Have done upgrades with both dnf update/upgrade, and GUI based upgrades on this system, and I switch between them fairly frequently and randomly. A detailed walkthrough of what happened exactly when the issue occurred (when you (re)booted your machine(s), when you started or closed the browser(s), whether you clicked through any errors or messages, etc.): I think most of the times, this was in first startup of Firefox after a a system upgrade. I don't remember precisely if it was after rebooting or not, though I want to say it usually was after a reboot. That said, I'll try to keep track of it next time it occurs. It has happened at least a few times. If it happened after an upgrade, whether your browser was running during the upgrade (and whether it complained or crashed): No information at this time. I don't remember any browser crashes or complaints, since I don't see that usually. What exactly was lost/reset, and what the intended setting/value was previously: The usual loss has been only the home page setting, reverting to the Custom URL start.fedoraproject.org page. The intended setting, and the one I usually set it back to, is the Firefox Home (Default) setting. ------------------- I can try to see if a dnf downgrade and upgrade triggers the issue. Will reply if I see anything. Adding note: did not see any change of page using simple dnf downgrade & dnf upgrade on either side after. Did not see any change after doing a dnf downgrade and a system wide GUI upgrade either. Due to unexpected personal life stuff I don't think I will be able to help with this as I originally intended. Sorry for the sudden change. I hope someone else can help work this out. If anyone wants to take over the effort, feel free to self-assign. Even though Lina isn't able to monitor this issue anymore, I'm going to add a note for now. I did see the homepage change again in my browser today, back to Fedora default. Of critical note: for me, **this seems to have happened without a reboot happening, nor any update to Firefox itself that I was aware of**. My browser had already been open still, though I had been away from my system for a few days (call it 2 days). The windows/tabs I had opened were still here, and at that time, I'm pretty sure the homepage was normal. However, opening a new window today showed a change to the homepage back to the Fedora start page. Firefox also still shows firefox-149.0-4.fc43 as my package version, so as far as I can tell, no Firefox update has occurred. That means this issue popped up without me updating Firefox itself. I do have backups of the folders per Lina's instructions. For confidentality reasons, since this includes my profile folder, I will not attach this here directly on a publicly visible ticket, at least not in full. Of note, I do see two different extension updates between one that had the right homepage and one that was wrong: Sky Follower Bridge - an extension that is meant to manage Twitter->Bluesky transitions, and Bitwarden Password manager, not sure if that's relevant. I did do a sanity check on the other Fedora system I have at home just in case that system may have been the one with the issue and it syncs (it's also powered on), but as it turns out, checking it, it isn't actually signed in to Firefox sync. That means it shouldn't have contributed. Everything else is per my above. I do not want to touch the upstream comment with my notes since that's specific to fixing the potential underlying. Please let me know if you find anything actionable. Thanks. Hello, This bug maybe connected to a likely recurring issue on my current set-up.
it has happened for atleast 5 times in a row for the past month now (including the time im posting this).
Update Method: sudo dnf update --refresh, flatpak update
Firefox Sync enabled. and I use my Poco X4gt with Firefox Mobile synced. tho I dont see issues on my phones Firefox.
How this issue occurs: I believe it first occured on my end when I was actively using my pc, I was simply using Firefox and after closing and opening firefox I noticed that all my accounts have been logged out. now when I open Firefox after a PC boot/restart, the same issue occurs aswell. I'm still unsure if it triggers whenever Firefox is closed after a brief period of time and opening it, I'll be providing an update when it happens again.
Did it happen after an upgrade: I dont remember this bug occuring after an update but what I do remember was doing a system hoping to get a fix for when this issue started
What exactly was lost/reset: was all accounts logged out in everysite im logged in, but It doesnt seem to wipe out all my prefs and bookmarks cuz I use Firefox sync.
Note: I think this also occurs on Zen. 2 days ago when this issue happened on Firefox, I switched to Zen briefly and logged(google, reddit etc.) all my account there, next day I saw all my logged accounts have been logged out aswell. I also have Brave installed and it doesnt appear to be occuring there.
