Firefox Support Forum

I want to change background color in Firefox from white to gray (because my eyes get tired of white)

I try to change it this way: Preferences -> Language and appearance -> Font -> Colors

But it does not work as expected on some complex web sites. All I want to do is to darken the background, but not to change color of other elenments (links, text, scrollbars).

Can I do it in Firefox ? How [Preferences -> Language and appearance -> Font -> Colors] works in Firefox? Perhaps, there is some "override css" for the entire browser?

Firefox browser fails EVERY TIME ON ALL SITES to load the video player: Need a fix for this

Quoting Error Msg = "Sorry, the video player failed to load.(Error Code: 101104)"

Funny WHY YOU ALL DON'T WORK BUT... Safari works just fine every time

And Firefox DOES NOT, NOT EVEN 1 TIME

Hello,

I frequently have used the Firefox screen shot tool in the past. However I went to use it today (11/16/21) and it is nowhere to be found. I was curious if this has been removed in the most recent update?

Thanks, Sean

Hi all,

I recently got onto Firefox but I have been running into the following error when I try to search on google or log into gmail.

SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT

Sometimes google works, and other times it doesn't. It's really hit or miss and I am not sure what to do. I noticed other people have had this same issue and I find the solutions do not work. When i wait a while, the problem seems to go away, but it will come back randomly.

Has anyone run into this recently and found a resolution? I find it very annoying to have to use Chrome when this happens. Please help.

After a recent update, my home button is now MISSING! Gone! Do not tell me to take a screenshot because that is not available for the menu or bookmarks bar. Why would you erase my home button in an update?

Firefox 94.0 crashes on startup, see for ex bp-3c45baeb-9cc8-4b9b-aedc-0a5030211105. It starts with -safe-mode but not if I disable all extensions. Ubuntu 20.04 on 10 year old Dell T3400.

Hello,

My name is Marina. I'm user of Mozilla for a long time. I have saved all my working link in the tool Speed Dial. It was for 3 years. It all my work. Today I'm shocked and don't know how I can restart it. Could you please help me with this issue?

I am getting errors from online web forms that tell me I must have JavaScript enabled to continue, but when I check about:config, it shows Enable JavaScript to be True?? Is there some reason why this may happen, or do I just need to use a better browser?? Thanks in advance!!

Recently lost all login/password data in firefox. After browsing the support I discovered that I have a corrupt logins.json file, around 270kb in size, and a logins.json file around 10kb in size.

Renaming the corrupt file to logins.json doesn't seem to recover the passwords/logins (even temporarily). Tried rolling firefox back to an older version and that didn't work either.

Does anyone have any ideas on how to fix the corrupt file?

Thanks.

Firefox still won't play the videos on MSN websites. All other websites are ok. This is a known problem that goes back almost ten years now.

All cookies and other cache items have been cleared and Firefox has been refreshed and it still does the same exact thing only on MSN websites. All other websites are ok and all other browsers except Firefox have no issues playing videos on MSN.
