I am experiencing an issue where clicking links inside Thunderbird emails forces Microsoft Edge to launch a completely brand new window with a blank profile (no extensions, default settings). It does not open as a new tab in my active window.

My environment details:

• OS: Windows 11 (Version 25H2) • Default Browser: Microsoft Edge (Only one profile exists under edge://settings/profiles, no Workspaces used). • Thunderbird version: Latest stable release.

When Thunderbird passes the HTTP/HTTPS link to Windows, Edge seems to ignore the standard "Default" user data directory profile and launches a temporary or guest-like profile container instead.

Is this a known bug in how Thunderbird handles external URI handlers, or is it an Edge registry/default app assignment issue? Any help or workaround config settings would be appreciated. Thank you!

I find that my desktop browser firefox is very slow or doesn't work at all on a lot of websites like amazon or fortnine.

My internet connection and computer are not the issue: 270Mbps (wired connection) Processor AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz) Installed RAM 32.0 GB (31.1 GB usable) Graphics card NVIDIA GeForce RTX 4070 Ti SUPER (16 GB) Storage 3.58 TB of 10.92 TB used System type 64-bit operating system, x64-based processor (Windows 11)

My old PC and my mobile phone runs these website fine.

Sometimes the website will work for a moment, but stop and just load for ever after I open a new tab or clink a link. My task manager doesn't show any ethernet usage despite the tabs indicating they are trying to load. Refreshing the tabs does nothing and no matter how long I leave them they don't load. All my drivers, OS and programs are up to date. I have disabled my enhanced tracking protection and I don't have any adblockers. I have tried using the CMD "ipconfig -renew" and using ccleaner to clear out my cookies and cache but, nothing seems to have any lasting effect.

I am losing my mind trying to fix this. Why can I not browse the internet on my PC?

Any help on this would be amazing and much appreciated.

Sincerely, Calvin

Everytime I restart and open firefox and then try to access facebook, sometimes google, n=some news websites and probably other apps, I get a captcha, but it repeats no matter how many times I get it right.

I was advised to do this, but it's still happening: https://www.youtube.com/watch?v=6fX0_wiVKhw

But even that's stopped working.

I cannot access facebook and I need it for work (small org, no IT section to ask), and can't access some new sites.

I've gone to basic security settings, but that doesn't help.

What to do?

Hi, I paid £7 donation in order to be able to download Thunderbird on my desktop but I couldn't set up my email account and hence I would like a refund. the email account I was trying to set up is shelan.mahmood@radorris.com which is on dynadot host.

Firefox has this pop-up warning that tells me that my http connection on my home network isn't secure. I need a way to disable this. The reason being that Firefox' pop-up blocks me from accessing my password mangers pop-up which is hidden beneath the Firefox one. Please help and thank you.

When I try to forward email with attachment. I get a error message stating I dont have access for the attached file so every time I have to remove the attachment in the email and download the attachment from original email and attach to my email. Which is frustrating and time consuming process.

What I thick is there is storage path issue with my email setup.

Please assist to resolve this issue.

When I have video playing in Firefox's PIP window (ex: YT) and when I enter full-screen mode in browser, the windows 11 taskbar does not disappear.

It works normally when there is no PIP window.

I have uploaded pictures of: - Not full-screen and with PIP window - Full-screen and with PIP window - Full-screen and without PIP window

My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

Hey, I'd like to switch from Outlook to Thunderbird. I’ve already tried switching to Thunderbird once when I switched to Linux, but—now to my question: The most important feature for me is being able to use different colors in the calendar to mark appointments. I wasn’t able to get this to work on Linux, even with AI. Isn’t this option available? But if people are switching away from Outlook, surely a small feature like this shouldn’t be a problem?

Can anyone help me with this?

when I use Firefox continuously for a long time..., it’s it’s continuously become freeze and kick me out ....I need a solution of this...as soon as possible. .And i also need the group folder create feature like chrome
