Firefox-Hilfeforum

The blinking screen is on ebay but it just keeps on blinking. I have tried other programs and it only happens with this one and only with ebay. This is the new tab stuff: https://www.ebay.com/itm/401568771184?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D265563%26meid%3D7245a46a376945799ec6d6e8ae3176fa%26pid%3D101967%26rk%3D1%26rkt%3D1%26itm%3D401568771184%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DPersonalizedTopicsV2WithDynamicSizeRanker%26brand%3DFintie&_trksid=p4375194.c101967.m162920&_trkparms=parentrq%3A88a4a82d18f0ad8bbb523870fffffa70%7Cpageci%3Ab38440d1-149b-11ef-b242-1adf3ab78462%7Ciid%3A1%7Cvlpname%3Avlp_homepage&afsrc=1&mkevt=1&showcs=1

Thoughts?

For some reason, the bullets used to hide a password are not rendered properly in Firefox. As shown by the first uploaded image, they are displayed as big white-filled circles.

This problem does not occur on chromium-based browsers, as shown by the second uploaded image, which is a screenshot taken from chromium, on the exact same session.

I have already done the following:

• verified that the "Allow pages to choose their own fonts, instead of your selections above" box is checked in my preferences. I have also tried disabling and re-enabling this option
• launched FF in troubleshoot mode to disable extensions and hardware acceleration
• verified that gfx.downloadable_fonts.enabled is set true in my about:config

All of these attempts however failed to solve the problem.

This problem is occurring on a fresh install of a Linux distro, so I first thought that I might be missing some fonts, but the problem might lie somewhere else since the symbols are properly displayed in chromium-based browsers.

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?
