The background image for the icons is supposed to come from www.gs2020-08-09T20:35:37-07:00tuhinmitra190221https://support.mozilla.org/vi/questions/1298594#answer-1340062<p>Now, I discovered something more.
The background image for the icons is supposed to come from <a href="http://www.gstatic.com" rel="nofollow">www.gstatic.com</a>, but the images are not loading because the website is not able to open on firefox.
I tried copying the image link from the gmail website. And tried to open it on firefox, but it's not opening with a message:
Did not connect: Potential Security Risk
(and there's no way to resolve this)
I was trying to open the following link, (opens perfectly on other browsers)

</p>I checked all the possible options you have mentioned in your answer for any possibility of deviatio2020-08-09T20:21:47-07:00tuhinmitra190221https://support.mozilla.org/vi/questions/1298594#answer-1340059<p>I checked all the possible options you have mentioned in your answer for any possibility of deviation. But all of them are as expected. And to be noted that, I use Ublock origin, and I have check it's related options to see if anything you mentioned was checked. And everything was just fine. Also I want to grab your attention on the fact that, only 1 icon is visible in the gmail page. why the others are invisible?
also here's is the link to the web console for error messages, to see if anything unusual is happening, now if this problem gets fixed I'll be really happy.
