Firefox mozilla recently updated, now the bookmark side bar has made the fonts dark on a dark background, now unreadable. How do I change the fonts back to white on a dark background?

I have used TB a long time. It is not now working. I never had a Password? I do have a Mozilla PW (not given here) donated several years ago. This is the story. I got a new phone. Didn't remember my Google PW. The sales man decided to redo my PW. It screwed up Google. Now I get the screen attached. The screen does not work and Thunderbird does not RUN. I get calendar and can write but not send or receive??? Second screeen See attachment. All my mail is via GMail. Perhaps I need to remove TB and reinstall???? Please help this TEXAN in Humble, TX tele <redacted> HELP

For a couple of months now I have not been able to keep the email client logged into my email account. Every so often I have needed to re-enter my email password in download my emails. However, this does not happen with my email on my Apple iphone, it functions normally. Last year, I added a laptop email using Thunderbird and it also is now having this issue starting about the same time as my desktop. I did not have any issues with my email until several weeks ago and it happens on both computers. I asked here what to check, and followed the instructions given here, still no change. In fact, on my desktop, it no longer will download any emails, no matter how many times I enter my password.

I use the desktop for my regular email use, with the laptop used for when I travel. The iPhone is mostly as notification of emails so I can answer on my desktop.

Let me repeat, everything has worked well and without issues until a few weeks ago. I made no changes in my settings prior to that, no changes to my internet provider, no other changes than normal software updates to Thunderbird.

Thank you for your past guidance and for future help.

Looking for a way to configure the "Share the screen" permission present in permissions for individual sites via GPO. I am aware of this doc but I can't find anything for setting this permission. Specifically, to block it for all sites with an explicit allow list.

The "Preferences" option won't suffice as permissions are stored in permissions.sqllite and are not part of the about:config preferences. The "Permissions" grouping lacks... the majority of the possible site permissions as well.

I can get to the "stored passwords" box, but the email I need to change the password for isn't listed there. I have tried to send and receive messages but nothing makes a "enter your password" box pop up. All I get when it tries to retrieve messages from Gmail is a box to give my email, (just that, not a password) and then an error message that it won't work and there is no more information. I'm using Linux. I've had both this particular email address (as well as others) and Thunderbird for years, perhaps two decades, and I can't figure out what to do now. I was going to change all my email passwords for security reasons, but there's no way I can do that until I can get Thunderbird working with POP access again. Thank you.

After installing upgrade to 139.0.2, POP downloads failed. Last was on 6/19/2025 at 8:19PM. I deleted both saved passwords.. Went to AOL and generated a new APP password but there was no way to upgrade to it. I sent a test message to myself [ smtp] and AOL logged me in and TB generated the saved password oauth://login.aol.com (mail-w).

However even with shutdown TB and restart, there was no request for a POP password [ such as the new AOL APP generated one. What should I do? Is this a bug? I can read and use AOL mail on my browser [EDGE]. LKint@verizon.net

Please forgive a very basic question. I think I know the answer but would appreciate having the correct one from the pros.

My wife and I each have Thunderbird installed on our computers. While we each have individual email addresses, we also have one email address we share, and we access it via Thunderbird.

If I'm marking certain messages as junk on my computer, will that designation only apply to my computer or, because of the common email address, will it mark those same messages as junk on my wife's computer?

Thanks for any help with this.

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don

I have just installed firefox on my new computer. I had firefox on my old computer and laptop that are both still running. It has pulled in a list of mostly obsolete accounts and passwords which are listed when I select "passwords" I did not ask firefox to do this. why has it done this. what else may it have done that I don't know about

I'm finding some web pages are not working correctly or are not working at all. I know it's not the web page as other browser's are working fine. Any help with this would be greatly appreciated.

Why does Firefox mobile for iOS look different on my iPhone 13 pro max vs my wife's iPhone 12 pro max? both UTD on iOS version. I suspect that I must be missing something in settings, but cannot figure this out. See images below.

On my iPhone 13 Pro Max, the Firefox app has the nice home button, tab button, and hamburger menu button on the bottom (address bar on top both cases). On my wife's iPhone 12 Pro Max, it has the "+" for new tab, the 3 dots instead of hamburger menu, and then the tab button. I much prefer the layout on my phone, as does my wife, but I cannot figure out how to change her layout to match mine.

Any help would be much appreciated!

For first time received email from breach-alerts@mozilla.com. Title is: Your monthly Mozilla Monitor report. Is this a scam? Other people have asked this question and Mozilla Firefox company has not made any attempt to answer these serious questions. If I do not hear back from Mozilla Firefox within a week I might remove Mozilla Firefox and use another company.

I use Spectrum (brighthouse.com) for my email server. I am using it on my current laptop. I have tried to put the same settings onto my new laptop and it won't work. I have contacted Spectrum and they are the correct settings. Now it is asking for a new password. that also didn't work. I am still using my previous password on my old laptop and that is working.

I am having some trouble getting Thunderbird to display all my messages. I tried troubleshooting mode and found that all the messages were displayed. Restarting in normal mode having disabled my extensions and hardware acceleration, the problem returned and I could not see most of my messages. So I need to make the other changes that troubleshooting mode makes. These are described at https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird as

• Window and sidebar size and position settings (described in terms of Firefox)
• userChrome and userContent customizations ; see userChrome.css and .js and userContent are unsupported

I do not understand what these are and how I can set them for routine use. Can someone point me to an explanation? Thanks.
