I used Edge as my default browser. No issues. Then, Microsoft, in their infinite wisdom started asking for verification everytime I logged into a site. So, I deleted it and changed to Chrome. I set Chrome as my default browser.

But T'Bird still wants to open links to Edge, aka Microsoaft, even though I have completely wiped Edge off of my PC.

According to help, T'bird should recognize my default browser and use that. It isn't. I went into General, but there is NO section labeled 'Default Browser' . A search on 'Default Browser' yields zero results.

I am at a loss.

Thx

I use Thunderbird Mail Client to access multiple Synology MailPlus accounts and accounts from Gmail and other services


Everytime ! Weekly! After Microsoft pushes another update I have to reconfigure Thunderbird to access Synology MailPlus accounts to receive mail. Mail on GMAIL, SPECTRUM and other mail services are not affected.

Microsoft is breaking something preventing only Thunderbird from retrieving mail from MailPlus Server.

I have to remove then add the accounts back in, Retrieving saved Profiles does not work to fix the problem.

I'm trying to use two screens so I can work with YouTube playing on the secondary screen. It works fine until I switch YouTube to full screen. It does fill the secondary screen fine and the video plays, but then my main screen goes black. I can swipe the screen and that brings back my main screen, but then it puts the black screen on my secondary screen. The best way I can explain it is that there seems to be a third screen option (let's call it screen two) that's completely black that's in between the main screen (screen one) and secondary screen (screen three). I can have screen one and two or two and three, but not one and three.

Any suggestions?

Good day

I have Firefox 137.0.1 (aarch64 ) running on my Raspberry pi 5 ( 8G Memory ) ( Ubuntu). I have been using this Desktop-settup for 2 years now without problems and all of a sudden, I get a lag on my sound when watching a video. And I do recall observing that an automatic update was done during the past few days.

So I can only assume that the update is to blame for this. Has anyone else noticed something?

I tried searching for a way to report this problem to the developers but I have not found anything.

Perhaps the community can suggest a way for me to pass this to the developers ?

Thank you very much in advance.

As of today, when I launch firefox, all of my tabs (which have been working fine for the last several days) crash.

https://i.imgur.com/7vrmvam.png

By disabling all of my addons, I get this to go away - and by testing addons one at a time I am able to determine that: -Ublock Origin -Kaskpersky Password Manager Cause all of my tabs to crash.

Whereas: -Sponsorblock for Youtube -Youtube Nonstop Both crash if I visit youtube, but don't affect the browser otherwise.

So it seems like ALL addons are currently broken when they try to affect a tab?

Since the last update (as of the 8th of April 2025) on the android version of the app, the browser seems unable to play videos in the picture in picture feature. The screen will get minimized, yes, but wherein before the minimization was the video still playing in small, now it is like a chopped version of the webpage. Posted a screen recording vid on tumblr to exemplify because screenshots alone don't do it justice. PiP Issue demonstrated

I have a laptop ( screen 1) connected to an external monitor screen 2) and extending the desktop. Firefox is running on the external monitor and a site I use has frequent pop up windows with tick boxes to select. With Chrome & Edge I can get the Popup window to open on the external monitor where the browser is running, but with Firefox the pop up window always opens on the Laptop screen. Is there a setting to get the pop up window to open on the same screen that Firefox is open on?

Hello,

I'm experiencing performance issues when loading webpages on Firefox on my Pixel A phone. I usually keep only one tab open and run uBlock Origin. I mainly visit sites like Best Buy and Amazon, but honestly, all webpages take forever to load.

Could this be due to the 8GB of RAM on the Pixel A series? On my Samsung S24 Ultra, I rarely run into these issues.

I love Firefox and will continue to support it, but this is really heartbreaking. Any help or suggestions would be greatly appreciated!

Thanks in advance!

iMac crashed while firefox was open. I've reinstalled firefox, deleted the caches and history, deleted user data.

Launched firefox to what seems to be a clean version (had to sign in, also not bookmarks showing.

Launch is quick. However, websites, such as google.com will not open. No error message, just little dots at the top of the tab going back and forth, then nothing.

Other browsers are able to open websites (I'm using Chrome to access this).

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.
