I'm on 76.0.1 and Firefox for some reason stopped showing youtube thumbnails. Other browsers show them perfectly fine but since Firefox is my main browser I would appreciate some help with this problem. Exactly this issue: https://support.mozilla.org/en-US/questions/1271112 As soon as I delete the site-specific configuration data, from the History option on bar menu, the thumbnails come back inmediately, no reload needed. But when reload the tab, or open a new one, the thumbnails dissapear again. Thanks in advance for the help.

Thunderbird won't send my emails: An error occurred while sending mail: The mail server sent an incorrect greeting: resomta-ch2-12v.sys.comcast.net resomta-ch2-12v.sys.comcast.net CSI IP 173.244.44.13 is not permitted to send messages. Please contact support if you feel this is in error..

Hi there,

My custom font (avenir) displays fine in all other browsers except Firefox. My site is: https://madebycircular.com.au/

Here is my code:

@font-face {

 font-family: 'avenir-book';
 font-weight: normal;
 src: url('fonts/avenir-book/avenir-book.woff2') format('woff2'), /* Super Modern Browsers */
      url('fonts/avenir-book/avenir-book.woff') format('woff'), /* Pretty Modern Browsers */
      url('fonts/avenir-book/avenir-book.ttf')  format('truetype'), /* Safari, Android, iOS */

}

I can't figure out what is wrong.

Thanks Clare

Recently, after 5/6 emails being sent, suddenly I got the error msg. as shown below:

"The size of the message you are trying to send exceeds a temporary size limit of the server. The message was not sent; try to reduce the message size or wait some time and try again. The server responded: 452 4.1.0 <dpw8445@austin.rr.com> service temporarily unavailable. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1440."

What does it mean? What should I do? Spectrum Support provided no info or solution. Can someone help? Your response will be greatly appreciated.

By the way, after I shut down my pc and started it again, I could send 5/6 emails. Then the same problem came back. Pls. help. Thx. David Wang

I closed Firefox browser on my computer completely today, when all my tabs were still open. Usually, if I do that and then open Firefox again, it restores all my tabs automatically.

I want to avoid that to prevent other people using my computer from seeing my tabs, but I don't currently have access to my computer, only my phone.

In other words, I want to disable my previously open tabs from opening when Firefox is opened.

Here is what I did: 1. Signed in with Firefox on my phone 2. Synced 3. Deleted history 4. Went to *phone* browser settings and chose not to restore tabs (in settings - advanced).

Would that be enough or is there something else I can do?

Thank you.

I have 3-4 different profiles running, one for work, one for using a proxy, one for developing (which turns off certain security features as I ONLY run my own code on it). I could have sworn that back in the old days when I unchecked the "Use the selected ... without asking ..." button that every time I started firefox by opening a link or clicking the icon for firefox that it would pop up the "Choose User Profile" dialog. Now it just seems to have decided to push it to some arbitrary profile, which for now seems to be my work one. I don't think it's stable and seems to be the first profile that I run when I start starting up firefox profiles. This is a problem if it randomly decides to start in my insecure for dev only profile.

What I did:

• Created a few profiles
• Started up multiple profiles at once w/ firefox -P
• Unchecked the "Use the selected ...." checkbox

What I expected:

• Bring up profile chooser dialog every time firefox starts

What's actually happening:

• It's picking a profile to start (not clear how it's choosing) and just starting with no dialog.

I'm running 68.8.0 esr 64-bit. Is this the new expected behavior, am I doing something wrong, or do I need to file a bug?

Hello everyone,

Is it possible to control Firefox 76 on Linux from D-bus ? I listed all available services with "qdbus" utility, but there is nothing like firefox/mozilla. Also, I browsed source code, and I saw D-bus support seems to be there. Thank you

Hello,

I just noticed I'm unable to sign in to Firefox Private Network anymore. I've following the instructions on the following article and there are not any updates for it:

https://support.mozilla.org/en-US/kb/bad-request-error-firefox-private-network-extensio

I have gone ahead and captured my network logging as one admin suggested in an archived thread. I'm running Firefox v76.0.1 (64-bit) on Mac OSX.

Looking for help with this issue.

I did the foxfire refresh. After it opened back up my toolbar favorites are gone. I went back to the refresh page and it says that it saved my favorites and tool bar favorites. Where are they???? or how can I go back to the old version??? I followed the instructions of where my tool bar favorites are stored and they are not in the library. So very frustrated!!!!~

When I first downloaded Firefox, I instantly went to transfer data from browser to browser. It did import the data, just not the right data. When I transferred it, I noticed it was actually the data from two years ago instead of what I currently have.

I checked https://support.mozilla.org/en-US/kb/accounts-blocked but I am not receiving any email from firefox.

When I open the browser, Amazon and YouTube are right there as Top Sites. I want to add at least one more to the list--my local library--but I can't find any instructions on how to do that. Whole lot of generalities, but nothing specific. Help!

every time i try to open up a pinterest page, it shows up completely blank. nothing on the screen. i've searched for solutions, a few said to clear the cache and i did. it works, but only once. if i reload the page or open a new pinterest page, it will be blank, and then i have to go back to history and forget the site again. the only extension i have is forest, and i don't think that has anything to do with it.

Thunderbird Version 68.8.1

I get the following message after sending 1 email, why ?.

An error occurred while sending mail. The mail server responded 550 5. 7. 1 xxxxxxxxxx Relaying denied. IP name possibly forged. xxxxxxxxxxxx Please check the message recipient xxxxxxxxxx and try again

The emails I am trying to send are generally a reply to incoming emails so the addresses are good, it also happens to known email addresses. If i close the program and restart it, the first email goes then I get the same message and failure to send.

I changed the password on Thunderbird 68 (Windows 10) and my Iphone and IPad send and receive email but Thunderbird won't, even though it shows both the incoming and outgoing passwords are correct. I don't know what to do. Please help.

I need to get rid of Bing. It takes over Firefox every time I use it. Isn't there some way to block it for good? Thanks for any assistance you can give me. - Bob Thomas
