Hello,

When I select text in Firefox the selection is not highlighted. The selection itself does work (e.g. deleting a selected word) but is not visible. The problem occurs in all fields where text can be entered, so the URL space, the search field but also text field on a page like this one. The strange thing is that the problem also occurs in Thunderbird.

I am using Ubuntu 18.04.6 LTS, Firefox 99.0 and Thunderbird 91.8.1

Ive tried down loading all the required packages; I have the latest FireFox available ;but still get the message on you tube to update to latest Fire Fox. On Ubuntu 18.04the same message but includes a error code 99,999.

Disqus is not accepting ANY attempts to upload images and is fairly new...started rejecting image uploads a couple of weeks ago. Uploading still works fine on Chrome.

THIS is the error message:

Unfortunately your image upload failed. Please verify that your image is in a supported format (JPEG, PNG, or GIF) and under 5MB. If you continue seeing this error, please try again later.

Using FF 103.0 and Ubuntu 18.04. I tried again in troubleshooting mode...didn't help

(There are several sites that work well on Chrome but are glitchy one way or another on FFox. I don't like to use (or have to switch to) Chrome for workarounds!)

Is there something I can tweak on my FFox to fix this?
