Firefox popped up an offer to change the screen to dark, which I did. I don't like it, want to change it back. I went to settings but was unable to make the change.

I have used Firefox since version 1.5 and have loved it and the community since. However, since finally scrapping Windows and switching completely to linux, Firefox has been frequently troublesome with random crashes. The crashes occur on any website I may be on and for seemingly no reason. It happens when I'm in the middle of browsing a page, just opened a new tab, or even when Firefox is simply open and I'm active on another open application.

Environment is as follows:

OS: Zorin OS 18 (Latest patches) (Based on Ubuntu) Mobo: Asus Crosshair VI Hero (Latest available BIOS) CPU: Ryzen 9 5900XT GPU: EVGA GeForce RTX 3080 XC Gaming (10GB) Ram: 8GBx4 G.Skill TridentZ RGB DDR4 (3200) Sys Drive: Samsung 970Evo M.2 Nvme 500GB

Firefox is installed via Flatpack through the built in app store in Zorin OS.

The crashes will sometimes be constant as well. Such as when it crashes, crash reporter comes up, then I click "Restart Firefox" and the second I see the window, it crashes again. This has been a constant problem though at random times ever since I switched back to Linux about 5 months ago.

Any help would be greatly appreciated. I don't want to have to change my primary browser from one that I am generally so happy with, and is also the browser that I recommend to everyone.

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?

ThunderBird upgraded to v153.0. Since then EAS and TBSync have stopped working. Extension Manager have disabled them and report both are incompatible with TB v153.0.

The option to "Find an alternative add-on" for both fails to find an alternative version to work with TB v153.0

Are newer version of EAS and TBSynce imminent?

Hi, I just installed Elementary OS on a Dell M6800. The OS runs well, and I have multiple email accounts, so I installed Thunderbird from the Elementary AppCenter. It showed up as a flatpak install, but I went ahead.

Now, in the past when I tried to replace the .default-release file with one from another machine and rename it with the new filename (which is what I've always done to transfer my multiple emails and address book),

I went to the usual place, which has always been /home/myusername/.thunderbird/whatever.default-release, but it wasn't there. Going to Help/Troubleshooting Information/about:profiles shows it there, but won't open it when clicked on.

The only place I could find it was in /home/myusername/.var/app/org.mozilla.thunderbird/cache/thunderbird. But when I replaced and renamed the .default-release file there, and then restarted the app, I still did not have my old data. How do I go about this with a flatpak installation? Thanks in advance.

when I try and add my microsoft outlook account, it redirects to a webpage, which after saying yes a few times with an already signed in session, redirects to localhost 44645. localhost 44645 notably does not seemingly direct to anything, and thunderbird does not change. clicking "continue" re opens the microsoft webpage How should i connect my outlook account? system details; ``` OS: Linux Mint 22.3 x86_64 Host: ThinkPad L14 Gen 2a Kernel: 6.14.0-37-generic Uptime: 7 hours, 40 mins Packages: 2177 (dpkg) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Cinnamon 6.6.4 WM: Mutter (Muffin) WM Theme: Mint-Y-Dark-Aqua (Mint-Y) Theme: Mint-Y-Aqua [GTK2/3] Icons: Mint-Y-Sand [GTK2/3] Terminal: gnome-terminal CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics (16) @ 4.508GHz GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series Memory: 14803MiB ```

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

Hi I noticed that some old links in my history are automatically deleted. How to configure expiration rules (if possible) in order to keep links forever, until manual deletion? I know that links can be saved in the bookmarks, but when browsing the Internet, unless bookmarking everything :(, no one knows if a link can be useful in the future.

Thanks for your help

Sometimes, the bookmarks toolbar disappear and the history list became hidden for no clear reason. Then, after I reboot my laptop and log in again, everything is back to normal.

I have this issue with my reminders for peoples' birthdays. I have an event on their birthday that comes from my Google contacts. That event has a reminder 1 week in advance. When the 1-week mark hits, I get an undismissable notification from Thunderbird. I can close the reminder window, but it'll show back up within a minute or two. I've tried removing and re-adding this calendar but it doesn't matter. When I look at the details for the event, I see that the Organizer field is Unknown Organizer <unknownorganizer@calendar.google.com>. My regular email address is listed as an attendee. This has been happening for at least the last several months, perhaps more than a year.

Hello Mozilla VPN Support,

I recently purchased Mozilla VPN and installed it on my system using the Flatpak version.

My operating system is **Linux Mint 22.2**.

The problem is that the VPN connects successfully to any server, but after a short time it disconnects automatically. This happens with every server I try.

Interestingly, if I use the Mozilla VPN browser extension, it works correctly and stays connected. However, the browser extension does not provide access to all the countries that are available in the full VPN application.

Could you please help me determine why the Flatpak application keeps disconnecting and whether this is a known issue with Linux Mint 22.2 or the Flatpak version?

If you need any logs or additional information, I would be happy to provide them.

Thank you for your assistance.

Kind regards, Nikos

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!
