As described, firefox is entirely not working for any website. This happened after my computer crashed (hardware problem) and I restarted twice, but could be related to a firefox update that was waiting for me to restart.

Installed on android phone, imported account configurations using the the bar code method. Gmail accounts all good, but Microsoft accounts all fail. Multiple reinstallations have the same outcome.

The failure occurs at Passkey generation all with the same message "We're unable to complete your request server_error: The contextID supplied in the request did not have a matching cookie" or "Something went wrong trying to create a passkey. Please try again." It uses Brave Browser when doing this.

Any ideas on how to progress?

Thanks

I have at least one file that won't display on Version 149. However, the file and it's MSF are both still on my hard drive. I've tried a lot of things to get it to display, but nothing has helped.

This isn't a feature I ever needed or ever wanted. More than often, I accidentally group two or more tabs and have no idea how to ungroup them (yes, I know, there's some about:studies where I can remove stuff from grouped, BUT it's not a good mitigation). Firefox has been a great browser for decades. This new "feature" is rather disturbing than helpful. I understand some folks might need it, but please, at least provide a way to OPT OUT. Thank you!

I’ve been noticing an issue with YTS-type sites on Firefox. The site either loads partially, the player doesn’t start, or it keeps buffering without playing anything.

What’s strange is that the exact same site works perfectly fine on Chrome and other Chromium-based browsers. Videos load instantly there, but on Firefox it either breaks or takes forever.

Things I’ve already tried: – Cleared cache and cookies – Disabled all extensions – Tried in private window – Checked network (no issues)

It feels like something related to Firefox compatibility with the video player or scripts used on these sites.

I also tested another version here which seems to work better on Firefox:

ytsmx https://ytsmx.stream/

Not sure what’s different (maybe a different player or encoding), but it loads without issues for me.

Has anyone else faced this or knows what might be causing it?

I get scam messages that say "Trojan virus detected!" on Mozilla Firefox which I cannot delete. I have run antivirus scans which show there is no virus or malware. I have shut down the desk top. How can I go to reinstall Mozilla Firefox default settings or do you have another solution?

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

1. There is not a relevant "topic" above for this question 2. How can I print a 1 page email on 1 piece of paper? View headers are set to Normal. I get one page with From, To, Reply to, & Subject then body on next page. I used to just select Print and my emails printed normally. I have been using Thunderbird for more than 20 years with out this problem

Nach dem letzten Update auf Version 150.0 wurde ich auf den integrierten VPN-Support hingewiesen. Eine Aktivierung ist nicht nöglich, da ich die Aufforderung zur Aktivierung nicht finde. Gehöre ich noch nicht zu denAuserwählten oder verstehe ich etwas falsch?

I don't see this addressed recently and the fixes from previous versions don't work. Using Thunderbird 140.5.0esr (64-bit) on Mac OS Monterey 12.7.6. Since T-bird updated I have not been able to change font colors or highlight font any outgoing email and I can't see colors in my incoming emails. I can copy and paste incoming emails into a word document and the color formatting shows up. If I write an email in a word document, change the color then copy and paste this into an outgoing email it reverts to black font. I can change bold/italic/underline.

I disabled my two extensions and tried again - no change either sending or viewing received colors

Under Settings > Composition > HTML Style "Use reader’s default colors" is checked and under > Sending Style "Both HTML and Plain Text" are checked

I'm missing something here but can't figure it out!

The Firefox icon looks like it has a shopping cart on the top-left hand side. What is this for? It is only happening on the Windows 11 taskbar (not the desktop or menu shortcut).

How to make Firefox my default browser on my new computer a Windows 11 computer. I’m to the point where I’ve got a pop-up window, which says sync Firefox on your phone or tablet. I am asked toOpen Firefox on my mobile device. Then Go to the menu and tap sign in. That’s where I am. Now I’m asked to tap “ready to scan” and hold my phone over the code. Unfortunately, my Firefox app does not show a ready to scan option after I get to sign in. Help!!

Hello Everyone,

Background: Using Thunderbird for almost an year and extremely happy with the product set. I use it to access GMAIL via POP and use the settings "After the email gets downloaded to my computer, delete the GMAIL copy" (Settings attached).

My usage pattern which changed recently: Earlier, I will always download emails using Thunderbird every day and it was working perfectly. Recently I have to travel for few days and during those days I will access my GMAIL via my android mobile primarily and I download all the emails after my return.

Current Issue: Now after I return, all the mails gets downloaded, but it does not get deleted at GMail side (online). From the time I started using Thunderbird after my return, the newer emails from that time are getting downloaded and deleted but the old emails stay in GMail. Current inconvenience is it takes time to validate if all the important emails are downloaded and I cleanup the GMAIL manually and then we are all in sync. This continues until my next travel. I tried resetting the GMAIL POP settings and there is no improvement.

Any pointers or suggestions to resolve will be gladly appreciated. Thanks in advance!
