I take advantage of Firefox on Kubuntu, and for a very long time I had a difficulty with the tooltips: the characters had been printed in black on a black background (a barely totally different shade of black, however nonetheless very troublesome to learn).
I used to have an answer with Fashionable, but it surely broke in Firefox 57 (Firefox Quantum). Here’s a answer which works now, for anybody else with the identical challenge.
- Navigate to ~/.mozilla/firefox/
- Discover your Firefox profile: a folder with a reputation like 1rsnaite.default
- Navigate to ~/.mozilla/firefox/1rsnaite.default/chrome/ or whatnot (you would possibly must create the chrome/ folder)
- Utilizing your favorite textual content editor, open the file ~/.mozilla/firefox/1rsnaite.default/chrome/userChrome.css (creating it if crucial)
- On this file, put the next code:
-
/* AGENT_SHEET */ @namespace xul url(http://www.mozilla.org/keymaster/gatekeeper/there.is.solely.xul); #btTooltip, #un-toolbar-tooltip, #tooltip, .tooltip, #aHTMLTooltip, #urlTooltip, tooltip, #aHTMLTooltip, #urlTooltip, #brief-tooltip, #btTooltipTextBox, #un-toolbar-tooltip { shade:#FFFFFF !vital; } - Save and restart Firefox.
- In case you have a number of profiles, repeat for the opposite profiles.
