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?

I want to open online PDFs in Acrobat. I've modified the setting is in Firefox to "Always ask," yet when I click on a PDF it opens as it should AND Firefox automatically downloads the file to the Downloads folder even though that destination is greyed out in settings and the radial button for "Always Ask" is selected. How can I block this activity in either Firefox or in the registry.

NOTE: ALL OF THE SETTINGS IN FIREFOX SAY "ALWAYS ASK." This a software bug in Firefox, not a user switch setting. This activity began today (March 11, 2022) after months of normal, expected activity. I've reset Firefox and I've done a complete uninstall and clean install and this still happens.

I am a browser / add on moron? I have been a fan of opera for many years because i could group tabs (IE Family history, telecommunications, steam trains etc) Opera has a high overhead, is slow and i needed something better - A friend suggested Firefox - Its a winner.

So i have seen add ons that would allow me to group my tabs but have no idea how to install one or where i should go for help.?

Please point me in the right direction - Im happy to read information but hoped it would be a click and install

Thanks

1. Firefox for MacOS prompted me to "REFRESH" 2. After "REFRESH" Firefox is missing all my previous data (bookmarks, history, passwords etc). 3. "Old Firefox Data" folder is on the desktop 4. I have followed archived support help steps for this issue but did not restore previous Firefox profile. 5. Archived help solution says to ask the question again.

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

Prior to FF97 a simply setting to "false" the about:config, print.tab_modal.enabled setting allowed FF to always use the system dialog box when printing. However, in FF97, this is no longer the case. How can I set FF97 to always use the system print dialog box??

I almost always use Preview printing on my Macs to avoid multiple pages of garbage so this is fairly important to me...and it might help to save a few trees...

Hello, my old NAS on my intranet (not visible from outside) supports only TLS 1.0. How can I enable TLS on Firefox on a single IP and on a permanent base ? For obvious reasons I don't want to enable it in general..

Recently, I've been unable to view paid for video, for example on Netflix. I get the following error message:

The WidevineCdm Plugin has crashed. FATAL Clpp-Error [Category 6 - Code 6002]: {"browserError":""}

I'm using a macOS 10.95 and, says Firefox,:

"Note: The current version of Google Widevine is no longer compatible with older macOS versions such as OS X 10.9 and 10.10. Only macOS versions 10.11 and above are supported."

So my question, since it seems my mac is no longer compatible with Widevine, is whether there a way for me to watch video on Firefox? Perhaps with another plugin? Or no plugin? Perhaps this is an issue to take up with Widevine?

Thanks in advance.

Does anyone know how to get this thing, or something like it, working. For me, stopped functioning after Fx 89

Restart Button for Firefox. https://gist.github.com/Sporif/ad6e917d87787491538bac80d3c8918c#comments]

Only interested in the Restart function.

Windows did an update and now my firefox background is BLACK! I don't like the dark. I've gone into windows setting and changed it to light. I've gong into languages and changed it to white background and Black Text. This has changed nothing! Please I'm so frustrated. I can't work like this!

Recently I was having trouble using Firefox with my web based Outlook email and asked Microsoft for support. In their reply they recommended that I reset Firefox.

I am reluctant to do so as I don't want to lose all my add ons which have accumulated over time as I am not sure about how to get them back if I lose them with a reset.

Is there a way to reset Firefox but keep my add ons etc?

I would appreciate your advice and thank you in anticipation.

is there a text-to-speech feature baked in Firefox. if not so could you recommend me extensions like speechify in chrome which sounds natural and have many features.

Hi There, Before I could sign up to a website I was directed to install a VPN service and they prescribed me to get NORD VPN and I thought but why not using the VPN service that I already have which is Mozilla VPN. So I tried to lock on to the site but I just could not now what do I do. I already pay for Mozilla VPN and if I do have to get Nord then I will have to cancel my Mozilla VPN. Please could you advice me what to do.

I am using the current Firefox & Window 10. I own Adobe Acrobat 2017. The icon no longer appears in Fire Fox & the Adobe Acrobat Plug In Extension no longer appears in Firexfox. How do I reinstall Adobe Acrobat in Firefox? thank you

I downloaded Firefox 52 ESP to try and enable the java plugin. I had Java installed beforehand. However, even on this version, when I go to Options -> Extensions & Themes -> Plugins. I wanted to know if there is any way to actually install the Java Plugin, and if not, what version of Firefox would allow for that. Thanks.

If I'm using "Blue Theme by Valou" and then change the "New Tab Background Color" to a light blue (#b7dff0), the theme changes (when I don't want it to) and the "New Tab Background Color" does indeed change to light blue. Unfortunately, when I re-select "Blue Theme by Valou" by disabling the unwanted theme and enabling "Blue Theme by Valou", the new tab background color reverts to a default slate (nearly black) color -- the light blue background is no longer honored when I open a new tab.

Please let me know if you need more information.
