Firefox 技術支援討論區

My customer has a problem since about a month on Firefox (using it on a Terminal Server). The top of Firefox gets hidden by white and grey "bar" and he can not even use the "functions" of buttons behind that. -> Please see attached Print screens Lower part of the Favorites-bar is visible and also works if he clicks on it - everything above not visible and does not work for clicking.

The problem only comes up from time to time maybe once or twice a week. When he minimizes Firefox the application behind is visible normally. when he maximizes it again, same problem still visible in Firefox. When he closes RDP Session and reconnects - the problem disappears. When he turns off the monitor where Firefox is visible - Firefox gets move over to the other monitor and the problem disappears.

I am not 100% sure if this is a Firefox problem or Remote Desktop Problem (or maybe an add-in problem). But until now it only happened on Firefox!

He is always on the last recent version of Firefox, we just updated today to the latest version again - but I can not say yet, if the problem would still exist on the latest version from today.

"Error: "WWF2TUh4dnM=" - You're using an outdated browser or are using a Proxy service which is unsupported. Please update your browser or turn off your Proxy to continue, thank you."

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.
