hello, that's caused by the "Broadband Speed Test and Diagnostics" extension which hasn't been updated for a long time and seems to be incompatible with newer firefox version. please remove it in firefox > addons > extensions if you don't use it.
Hello,
Thank you very much for reply. I did as you suggested removed speed test and I guess now it is working ok. But I have to check further.
I have this problem too, and have never downloaded or used that add-on. There has to be some other issue. Anyone have any ideas?
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")
