No Function since FireFox 135

Since Firefox has updated to Version 135 Kee Browser Plugin is not working anymore.
OS: Windows 11 Pro 24H2 with all available updates installed.

Hi community,
Any solutions or ideas about the problem?
Thanks and kind regards,
Alex

It works for me (and in version 136) so it’s unlikely to be related to the update. Please check out all the advice in Troubleshooting and then supply some more information if nothing in that page helps.

Works fine with this versions:
Firefox x64 136.0
KeePass 2.58
KeePassRPC 2.0.2.0
Kee Browser extension 4.0.7


Windows 11 Home Version 24H2 (OS Build 26100.3323)

It doesn’t work for me.
Firefox x64 135.0.1 and 136.0
KeePass 2.57.1 and 2.58
KeePassRPC 2.0.2.0 (ports verified)
Kee Browser Extension 4.0.7
Windows 10 Home Version 10.0.19045 Build 19045

There’s a strange stripe on top of the popup windows but I cannot access to it.
