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?

I can't login to my Facebook account? But I can login to other browsers,

Can you please help me on this.

Thanks.

after confirmation and approval nothing changes on screen.

I am unable in run the installer for the updated version of Firefox on my android desktop. Are you able to help me?

Thank you in advance

Hello, so finally this happens to me too. I lost all my emails in Inbox before August 2025. I think it happened after one of these usual alerts 'you should compress emails'. I did this in the past 6, 7 years and nothing was lost so far. I also have plenty of space on my computer, that's not a thing. I tried a couple things I found in web but doesn't help. Couple emails that I had for example in an 'important' folder are still there. I'm really annoyed. I didn't had a glue at all that this compression alert will delete files in the inbox one day, only those in the trash box. Maybe there is a last chance to get them back but I'm afraid that they are gone forever and I will put everything from my inbox into an other folder in future or maybe even better go back to Apple Email where this never ever happened in the past 25 years.

Thank you, Chris

I'm struggling to disable this behavior of firefox. When I type "something: text", it's opening a pop-up asking "Open link with System Handler?".

I would rather just search the internet for "something: text".

How can I do that?

I've tried to play with parameters like network.protocol-handler.expose.something network.protocol-handler.app.something network.protocol-handler.external.something network.protocol-handler.warn-external.something

but didn't manage to do it

Hi, I open a lot of links on my andorid phone and want to read them on my laptop. I synched both devices so I am able to open my Android tabs from my laptop, but now I want to definitely close the pages I've read on both devices, but when I right-click on the tab in the 'tabs from other devices' list, the option "Close tab on Firefoxe #android#" is greyed, How can I use this very option I was looking for ?

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.

It would be nice to be able to add notes to passwords so I know what they are about and organise them into an alphabetic list. Another useful feature would be the ability to create folders to organise passwords into groups.

Distorted fonts and graphics. I've tried: 1. disabling graphic acceleration 2. change default fonts 3. reinstall firefox 4. remove extensions

Seems to be mostly fonts but perhaps also graphics. Only happens in firefox. Please help. Thanks

Nowadays safari can easily use uBlock origin lite to block ads and MS edge allows users to use adblockplus. However, Firefox iOS is still “ad friendly”, no way to block them 😭

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?
