Firefox Community Forum

Was reviewing my Settings. Looked under Privacy & Security, Browser Privacy, Certificates, View Certificates. The Certificate Manager has many listed under “Authorities.” Some look suspicious. How do I determine which are valid and which should be deleted?

Is Amazon disallowing this ?!?

Secure Connection Failed An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

I'm finding some web pages are not working correctly or are not working at all. I know it's not the web page as other browser's are working fine. Any help with this would be greatly appreciated.

Hi, upon seeing that Firefox 138 was available, I was surprised to see that my version of Firefox is still on 136. I'm on Kubuntu Oracular (24.10) and using the PPA at https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu oracular InRelease. After checking https://launchpad.net/~mozillateam/+archive/ubuntu/ppa and filtering for the different Ubuntu releases, it seems that both Noble and the newer Plucky have 138 available, but Oracular didn't even get 137.

Is there a reason for this?

My computer will likely update to 25.04 in the relatively near future (there is currently an updater bug that's delaying the rollout), but I'm still curious why this is two versions behind.

Yesterday evening I accidentally clicked on a setting that asked me to stop or deny something and I don't remember what it was. Today my bookmarks and history prior to yesterday evening is gone. Is there a way in the system to go back to yesterday evening and undo whatever I clicked and restore the missing history and bookmarks? I work on MacOS and am using the current version of Firefox 137.0.2 (64-bit)

Hi.

I want to ask the setting of theme.

If I don't set the theme, the color of window in private mode is dark (and I know I can change this setting on config.) The other hands, when I set Theme, the color for browser of private mode will be also changed the color of theme and it is same as default one.

I want to recognize which browser I'm using by the color of the window. I can do that if I don't set a theme. Is there any way to apply the theme only default browser or to apply different theme to private mode browser?

I can't seem to login to Twitch with the newest version of Firefox on Arch Linux. This was a completely fresh install of Arch and Firefox with no add-ons (on two different machines). Switching user agents doesn't seem to work either.

I'm not sure what this feature is called in Firefox lingo...

On my Mac, Firefox will remember which windows belong on which virtual desktops, and so open up with them on the correct (well, not exactly, but sorta) virtual desktops after a restart of the app.

On my new Windows 10 installation, though, Firefox has learned that a specific window was moved to virtual desktop 2, and now INSISTS that that window should always open on the desktop after a restart, regardless of on which desktop that window was actually placed when Firefox was shut down.

Is there a quick fix for this issue, or at least some way to disable this feature?

Thanks :)

When I run a Google search or any search engine, the results show a 2 line of UPSIDE down text ( Russian ? ) on top of each result. The page description underneath is the right way up and in english. Any ideas on how to fix this please ? SEE attached image.

While using Debian 12 on two workstations running version 136 the "update available" would appear on the screen and remain on the screen with no option to update or cancel.

Because this happened on 2 Debian 12 workstations, i would like to know if this is a known problem as I updated 139.01 an the issue continues.

You will noticed in the screen capture update available has no options other than "learn more"

All of a sudden one day my bookmarks vanished. This is annoying, but what's worse is that I'm unable to add more. I click on the little star at the top to try to save a page, and nothing happens. I go into the sidebar, try to do it there, nothing happens. I click Command D (on a Mac) to try it through the shortcut and nothing happens. I've tried signing in under different log ins to see if that's the problem, but that doesn't work either. I'm totally confused. Any help is appreciated.

Hi, I am curious to know why I can't completely remove the Dutch language in the language settings. When I installed the browser it was automatically set-up to Dutch - a language don't speak - then I was able to add English but some functions like spelling corrections are still in Dutch. I would like to get rid of it. I have the same problem with German on another computer. Thanks!

Hello, I am trying to login to my account on www.zazzle.com and use their site. Sometimes it will let me through and I can be on the site for about 20 minutes before a captcha comes up that says press and hold this button so we know you are not a bot. Well the button never works, it always errs out and gives me the message to please try again, and then locks me out of their site. I have tried clearing my cache and cookies, updating my browser, resetting the router, I don't have any VPN's, I have tried working in a private window, adding the website to the privacy exceptions, block pop up windows is unchecked, I am out of ideas, what do I do??

GM,

An individual website keeps defaulting to, and loading in, the German (https://de.website name here) language version. This has never, ever occurred previously. I have had no success in resetting the website back to the setting(s) which would have it load the page(s) in English, NOT German.

Thanks.
