Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

While I'm using Firefox, I try to go to a new website and Firefox says that it's installing a new version and I need to stop what I'm doing and restart. When Firefox restarts, it forces me to create a new profile and I've lost everything I had before.

This happens two or three times a day.

Hi, I use Firefox and would like to migrate over from Gmail to Thunderbird. I'm getting fedd up with Google trying to overpower me with everything.

Q1, if I download and install T/Bird will it run my gmail and icloud emails

Q2, will I have to e mail everyone to say not to use Gmail, they must now address me at T/Bird?

Q3, How easy is it to empower T/Bird to control my 2 mail accounts?

Cheers,

Colin

Hi, after latest update just now, the browsers uses up to 45gb of ram within a few minutes! Not sure what it is, I am on MACOS Sequia Version 15.6.1 (24G90) macbook pro M1

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.

Hi a few weeks ago i had the problem that my firefox-stored-passwords are gone and there are files named logins.json.corrupt and logins.json-1.corrupt to -4 The in dir backup was also corrupt. File length 122 -123 kb all nulls. If i look at the dates first to last, they span two weeks were i didnt notice the problem. PC is always hibernated after work. Except for one which i imported just before from edge at the end of the two week span No problem: logins replaced by external backup as i found here at the forum.

But: How can Firefox produce multiple corrupt files without noticing me? (I have saved them for reference) In that two weeks span logins using firefox passwords obviously worked. (I dont remember the details)

Then some updates and reboots. No problem. But after work i do always hibernation

TODAY: PC didnt survive hibernation. logins and in-dir backup are corrupt again.

What about a) checking better if something is going wrong (obiously you do something because you rename the files for some reason) b) Noticing the user c) And how on earth this can go wrong in the first place.

Now for the obscure: Both times somebody has just before posted something against the greatest President of all time at Fux Nus using this pc. Backdoor possible?

Thanks

Edit: Using Windows, no other problems with storage on the 1TB Samsung ssd

When I want to duplicate a tab, can I configure the 'duplicated' tab so it appears exactly next to the tab I'm duplicating instead of at the end of all the open tabs at the far right end of my browser? If I can't would it be too much of a bother to include that as an option we can configure? Maybe it's ridiculous or I'm using the interface wrong but it's super annoying to have to manually grab the duplicated tab and scoot it back next to the tab you duplicated from. Thanks!

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I am logged on to my Credit Union and attempt to download my statements. When using Firefox I get the message: {"Errors":["Authorization has been denied for this request."]}

When I contacted my CU, they said to add an URL to the Manage Exceptions. This worked, but I want to know why Firefox needs this but Chrome doesn't.

Today is 11-12-2025. After the last update a few days ago, many of my websites would not load up on firefox and when try on Edge or Chrome, they would work perfectly. I did a recovery back to 10-31-2025 and everything worked fine. Now I am afraid to do another update until I know what is going on. What would you suggest? Thanks,

Yesterday I was able, with someone's help, to turn off the feature in Thunderbird that is a pop-up on lower left of screen that a new email has come in. But now I want to also get rid of the sound. Didn't have this problem with my old computer and Windows 10. Or is this something I can only not have when speakers are turned off?

Hello there, today was released a new version of firefox. downloading it not only crashed my computer, it also removed all my history and bookmarks. is there any way to revert this?
