Just a few days ago, screenshot technique failed. I often copy an image from webpage. Right click technique. I am still able to do this. I have option of copy or Download. Download works but Copy does not. When I try to paste the copy into my Word document, I get a blank image (a square that indicates there was an image but the actual image is not there). How can I get the paste mechanism working again?

Hi. I want to sync with my work pc (it used to work just fine but when I synced to a newer third pc- successfully- it just stopped). When i try to sign in on the work pc it asks me for the primary password which it then FAILS to recognise to allow me to proceed! What's going on? I can't even log onto sites with saved passwords anymore. Any help appreciated.

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

I realize Facebook doesn't have a spell check feature,but is there a way my browser, Firefox, which I already have spell check enabled can somehow spell check Facebook when I chat? Can someone help? Thank you.

Today, I cannot open Cox E-mail using Firefox, but I can with Google Chrome (which I pretty much never use). See the error message below, can someone help? I have a Dell E6520 laptop running Window 7. Thanks.

Hopefully you can help. I know this may be a Microsoft issue or question but I'm having trouble in finding a reasonable way to contact them for help. My question is, my computer runs slow, and so I thought I would clean up my files by using the Microsoft disk clean up procedure. I did so. But, my specific question is what is a good number to have when the it says a given number of disk space can be cleaned up? For example, I believe when I first tried to clean the disk it said 5.1 GB of disk space could be cleaned. When I ran the disk clean process and it completed it then said 66 KB of disk space could be cleaned. So how much disk space did I gain or get cleaned up? And, if I can only clean up 66 KB of disk space is that indicative of not really needing to clean the disk any farther? Hopefully some one can help. While this may be a Microsoft issue, I believe the Firefox contributors have enough computer knowledge to help answer my question. At least that is my hope. Thank you.

Everything was fine until about an hour ago. Suddenly over half My tabs quit working. Either the display is weird and all text, or the page is blank, or there is a small "broken image" icon in the upper left... A few tabs are working fine. On X I get a notice saying, "Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com."

I tried turning off tracking (which was NOT "strict!!!"), and that did not fix the problem.

What is going one????

Is there a keyboard shortcut to remove cookies from the website? I mean the page I am currently on. And if there is no such shortcut, can I somehow create one myself?
