Unable to connect

Error code: 502 Bad Gateway

Try Again

I noticed a wierd popup when opening mozilla. It said "you're always starting mozilla when starting the pc". How and why does an internet browser have to have any information regarding when I boot my PC? What else does mozilla look at outside the browser environment?

If they claim it's needed for performance: Illogical, boot times have nothing to do with the internet browser. If referring to general performance then you can't possibly track and tailor every new piece of hardware that enters the market. Instead you make your browser with prerequisites that you yourself control (eg. install vcredist for this browser to work or something like that).

Why then is Mozilla monitoring my computer when the browser isn't even open or running?

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

Sadly Thunderbird often hangs, particularly if a network disk goes down. It is a strange hang, with the Inbox shown when hovering the task bar, but selecting it does not open the window. I have been observing this for perhaps 6 months.

In the past, it was sometimes possible to Close Window, else End Task, but neither have any effect. It seems that End Task is disabled.

Consequentky when Thunderbird hangs, the only way to restore Thunderbird functionality is to tidily close all other applications, restart Windows, which fails, hold power button for 5 seconds, then manually start again.

Why isn't Thunderbird killable?

hi, I'm switching from 1 PC to another. I can download Thunderbird easily, however when I try to open, I get a popup saying profile missing. and I can't open Thunderbird. no idea what happened. any advice please? thank you! Jeff

As of today, Thunderbird will not make contact with my servers and won't download emails. i had been having some issues with Thunderbird not sending emails last week. Plus, Firefox won't connect with my internet provider's website so I cannot access emails thru webmail. Firefox either times out or says connection could not be made. Could there be an issue within account settings?

I'm exploring Steam Deck desktop mode more and I'm running into issues with Firefox not rendering some videos on my personal website. I wasn't sure if it was a Steam Deck, KDE Plasma, Firefox, or an issue with something else, so I tested the same website with Vivaldi and the video played without any issues. This makes me feel like it's probably Firefox, but not totally sure yet.

I've already tried adjusting the autoplay media permissions for the website from the default to "Allow Audio and Video" in case that was doing something. I've also tested in Troubleshoot mode to see if the one extension I have installed was causing any issues and that didn't change anything either. Any other ideas I can try? Or, is there some way to determine if this needs a bug fix/there's nothing I can do on my end?

I need predictability where I can find it. Thunderbird opens how I left it, so I never know what's going to appear when I start it the next day. Isn't there some setting so that it always opens showing all 3 panes, regardless of my laziness at exit? It would also help with my autohotkey script if it knew what to expect. I suspect the lack of answers in my search suggests there is no such setting. How about a command line argument?

In one folder, one message received on 20th Feb keeps altering its date/time so that it appears AFTER replies I've sent in response. This has occurred following a problem with the same folder where several emails went missing, which I managed to restore with the Repair Folder function. Thought I might try looking in the file (not the MSF, the other one), but it's far too big for any text editor to open.

In my current version of Thunderbird, new messages show a dark blue subject line only until I click on them. After I open the message once, the blue highlight disappears. Is this the normal behavior now?

Is there any way to extend that same dark‑blue highlight to other emails as its really helpful to provide good contrast between individual emails.

Thanks, Steve

when i booted up my laptop this morning i notice all of my tab groups were gone. i know how to get to where the tab groups are held, but when i click on the down arrow thing none of my saved tab groups appear. is there any way i can get them back? i used them for art references so theyre pretty important to me
