Hi, I've been receiving the following rejection message as follows: jino.ru rejected your message to the following email addresses:

postmaster@pop3-server-spam.org The address you sent your message to wasn't found at the destination domain. It might be misspelled or it might not exist. Try to fix the problem by doing one or more of the following:

   Send the message again, but before you do, delete and retype the address. If your email program automatically suggests an address to use, don't select it.
   Clear the recipient AutoComplete cache in your email program by following the steps in this article: Status code 5.1.1. Then resend the message, but before you do, be sure to delete and retype the address.
   Contact the recipient by some other means (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.

The sender of the email gets those message. I get them also but I'm also getting the message that they send me. It's only doing it with my outlook account. Why is that? I checked it directly on the Outlook website and everything is OK. I can't understand why this is happening.

While watching a video in full screen mode, the screen periodically darkens for 2-3 seconds, after which the video continues, during the darkening the video stops and there is no sound

My Firefox browser used to open in full screen but for the last 2-3 months it only opens about 2/3 of the screen. Pressing F11 does not work. It only works if I press the centre icon in the upper right corner of the browser.

This happens every time I open the browser. I have looked on Google but nothing works for me. It used to work fine and I do not know what has happened. Another browser works fine but Firefox does not. Any assistance is greatly appreciated. Kind regards

TikTok might not be working due to a few common reasons like a poor internet connection, server problems on TikTok’s side, an outdated app version, or too much cached data. Sometimes, the app might crash or fail to load videos properly. Restarting the app, clearing cache, or updating it usually helps fix the problem. bold text

Hello I've been a Firefox user for decades; recently a problem suddenly appeared that I'd never encountered before; I mentioned it to you but you didn't see fit to reply. I have twice 'repaired' Firefox, to no avail. After hours of Internet research, I've discovered the nature of the problem: it's called FirefoxCP Isolated Web Content. According to the many forums I've consulted, you're perfectly aware of it. So I don't understand : - why you don't take the trouble to reply to a user with a problem. - and, above all, that you're perfectly aware of the problem and don't do everything in your power to solve it. As 'killing' an activity in my Mac's activity monitor every ten minutes is rapidly becoming unbearable, I'm going to have to change my browser, much to my chagrin. Farewell dear Firefox!

the pic in pic feature doesn't work. When I click the icon to go pic in pic Firefox opens a new full screen window with the video. I can't see any way to toggle it to be a small screen at the edge of the screen I'm working in.

Please advise.

Only hours after my previous use of the picture in picture function to watch YouTube via the mobile site on the app browser, the function suddenly stopped working.

It would play the videos when I was in other tabs, and with the app itself closed. However, as soon as I opened it as a picture in picture window, the video paused and refused to restart playing.

This far, I have:

• cleared the cache
• force quit the app and restarted
• double checked that picture in picture was enabled (it was)
• made sure the app is up to date (it is) and compatible with my phone (it is)
• made sure the Video Background Play Fit was still enabled and up to date (it is)

None of these issues has resolved the issue. As the issue is specific to the play to play function, and is not effected by closing the browser or switching tabs, I believe it is an issue with the function, not the site.

Everytime I open firefox i have to enable Picture-in-picture in settings, because it somehow gets dissabled everytime i close out of firefox, its annoying and I dont how to fix it, and cant find anyone else having this same problem.

since firefox 133.0.3 i can no longer use video controls in youtube. youtube video controls (scrolling an sound volume) work when youtube is in firefox picture in picture mode. when picture in picture is disabled in firefox settings youtube controls still not work.

thx for forcing me to use a feature i do not want. pls fix this.

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.

When using the PiP feature is there a way to switch whether it pauses the video when closing the PiP player?

Often if i want the audio to continue but dont want the popout player there and if I press the close button it will just stop the audio. If I select the PiP window and use the shortcut CTRL + SHIFT + ] the audio will continue playing as I want it however this is inconvenient and requires using the keyboard, is there any way to change it so that closing the popout player doesn't stop the tab from playing audio?

Over the last 6 months, and increasing number of websites don't open on Firefox. I've noticed it most consistently on any of the wikipedia/wikimedia pages, but it's not just those. When I type in an address and press return, or click on a link, the browser just acts as if nothing has happened. There does not show me the loading symbole. If I ask it to open a new tab with the site, the address appears on the tab, but the page itself is just black. Other browsers have no problem loading the same sites. I am on a mac, and using a VPN. Restarting the browser doesn't help, though restarting the computer sometimes does.

Thank you,

I loved the picture-in-picture mode. However, when I closed the picture in picture mode, the video automatically stopped. Is there any ways where the video still plays even after I closed the picture in picture mode?
