Φόρουμ υποστήριξης - Firefox

I have just started using Firefox and ticked that every internet tab is Firefox but every time I click new tab, it states "search with google or enter address" I cannot get into about:config to then get to browser.newtabpage.pinned How do I get rid of this Google message?

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

I recently changed to Firefox from chrome and the focus on security and privacy was a much needed upgrade. However, every time I close my windows I'm logged out of all my accounts. I checked all the settings that would have that effect even escalating it to a clean install and unfortunately nothing works. After checking the support forums this setting seemed to be the one that fixed things, attached is a screenshot showing that its unchecked and that there is cookie data stored, so I'm really at a loss.

Firefox browser no longer on W7 laptop. Followed instructions-downloaded setup and installer. Neither will do anything - message says no program association to implement thses files. Help!

My LastPass extension appears as a black box with an elipse. It is red when it is active. I have logged in to LastPass, and when I go to the extensions icon and select "Open Extension" nothing happens. It's not filling in any of my login information.

my electronic health record is freezing using Firefox on 2 different computers in 2 different locations. Internet speed 45 mbps at 1 location and 900 mbps at another. Able to use it on chrome.

I'm trying to run Java in the browser on Linux, but it's not working. I've gone all the way back to Ubuntu 7.10 where the default Java is included with the operating system by default, and it is NOT detected in the latest version of the web browser that it can run, which is 17.

Recently Youtube refuses to play any videos for me, saying adblockers are against their rules. I have uninstalled Adblock, and reset firefox totally. Youtube is still blocking me. It works fine on Chrome. Do I have to switch to Chrome permanently?

Have sold loads on Ebay using only Firefox as the browser. Tried to list another item a few days ago, and after entering the details on the first page (Item description and section to list it in) couldn't get beyond that page. The next page appeared not blank but as light grey filled rectangles where the text etc should be. Obviously tried reload. Same over the next day or so. In desperation, used Edge. No problems with that, using the same first page which Ebay had stored for me. Just tried again with Firefox - same fault.

I recently took a hit from potential malware while looking for a owners manual. I now have a popup that looks like the one attached. It looks to be from Mozilla, but I can't be sure. Can you help with this?
