Hello,

after an update up to Firefox 89.0 (64bit) on my elementaryOS 5.1.7 (based on Ubuntu 18.04) I've got a grey-colored rectangle in the upper part of my window that overlays all elements of websites (cf. attached screenshot), however I still could pass via hyperlinks if there are any under the rectangle. It is very light grey in light mode and dark grey in dark mode.

I've tried following steps according to possible solutions found in the Internet : - launch Firefox in safe mode (the rectangle disappears) - make sure the default theme is used - turn on/off the hardware acceleration - update or disable and delete all add-ons and plug-ins (rectangle still present in normal mode) - delete and reinstall Firefox with wiping all its files on the local machine (including /home/user/.mozilla and /etc/firefox* folders) - delete again and install the flatpak version


Nothing of the above helps except of the safe mode. As I have tried already to delete add-ons and plug-ins, what else can I disable to try to solve the issue in normal mode ?

I would appreciate your help as this is the only browser that I (want to) use on a daily basis. Thanks in advance!

Soluție aleasă

You can try to disable WebRender.

You can look at this pres on the about:config page page to disable WebRender.

  • gfx.webrender.force-disabled = true

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

Disabling WebRender has entirely solved my problem. Thank you a lot, cor-el !
