When I want to install a theme for my firefox there is an error which says:"Installation aborted because the add-on appears to be corrupt." And because of this error I cannot install any theme. Please help. Thank you...

I have created a custom firefox theme, others' themes also change the colour of the application menu at the right side of the browser when opened it will match the theme, i wanted mine to be either black or a dark red, but i dont know how to change that, at the moment it is white and doesnt match at all, please tell me how to change this please

I am searching through the Find more Themes page. They either don't open or I get a An unexpected error occurred when trying to open them. I've updated to the current version, and still not working.

Also I have Grammarly for Firefox added, for my word spell checker, but it keeps using the windows checker. How do I fix that.

I have a problem with contrast-free Firefox. I cannot see what tab is active what is passive. I tried to get better contrast by changing the theme with those available for Firefox. I have tried at least a dozen of them, but all get the sane destiny. It might take a couple of days or a couple of weeks, it comes. I mean after a short period my applied theme disappears and I get the same standard theme.

I have been using the them, Jesus is Lord for years. Suddenly when I open up the attach file box...it has changed colors and it is back on white. I can't do black background with white text. I tried changing it in several places with not avail. Can someone please explain why it suddenly changed colors on me and how to get the original white background with black type? Thanks, Carol

could you guide on what could i be able to do and how do i see those themes section where to see my all installed themes and how i can enable it so that I'll be able to see the changes on my browser?

Your themes aren't working right and for some reason the bookmarks sidebar has gone dark, and MY theme which I created is no longer available. The toolbar up top loses the icons for back space, forward, home, and refresh and I constantly have to re enable the theme to make them reappear. This is getting tiresome and needs fixing.
