Firefox Community Forum

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

I usually want spellchecks "English (United kingdom, large)" and "German (Germany)" active. Every few days to weeks it changes to a (single) random other language instead, like "German (Luxembourg)". Posts I've found elsewhere suggest changing display language (which should be unrelated and is already set to UK English), uninstalling all other dictionaries system-wide (which should not be necessary and is not acceptable), reinstalling Firefox entirely (but that's for cases where the correct dictionary was never selectable, I can select it, it just doesn't stay for long) or issues with syncing with other devices (but I don't change that setting on other devices, either). How do I stop spellcheck from changing and why does this even happen?

I am getting sick and tired of ytube video 153 error messages on the latest releases of Firefox when trying to access a ytube video. I use Firefox on Linux (Ubuntu and Mint) with multiple profiles and it didn't used to be this way!!

Even clearing the profile cache and history has unpredictable effect. The web is full of questions to this very issue with no definitive fix. It appears Firefox is not clearing things out properly even though the profile settings are set to delete everything upon exit.

What is the fix?? (or is there one?) A very frustrated longtime user.

Hello,

I have a question regarding automatic updates for Firefox.

I sometimes use a Linux live system (with pre-installed Firefox 140), and Firefox updates flawlessly through the „Help --> About Firefox“-setting.

Is the connection with the Mozilla-server encrypted (https:) during this update?

Are the updated files also checked for integrity?

thank you in advance

Hi,

I tried to edit my autofill to eliminate the +1 from my phone number i.e. (123) 456-7890 and clicked "save" but it just reverts back to +1(123)456-7890 forcing me to go in and manually enter it. Kind of defeats the purpose of autofill slightly.

Not sure if anyone can fix this but didn't know where to make a suggestion.

Why there is no option to use/configure a local running ai chatbot in the "Choose an AI chatbot to use in the Firefox" sidebar? Or does it exists and I didnt see it?

Wenn ich mich auf meinem Linux Rechner im Firefox anmelden möchte um alle meine Lesezeichen und Passwörter zu importieren bekomme ich die E-Mail mit dem Bestätigungscode viel zu spät! Es dauert ca. 20 bis 30 Minuten. Woran liegt das?

I have a firefox account that I use for work, which was created with my personal email address - "email"@"personalDomain".co.uk. When I try to log in using it I get a message saying that "personalDomain.co.uk" is not a valid email address. How can I log into my account which was created using this email address? The email address is valid and active, and I do have access to it.

Hello! Correctly saved passwords don't work when logging in. I either cut them directly from the login screen and paste them back into the same screen, or I have to type them in manually, and then it works. I've encountered this problem several times now, even on different computers. I can absolutely rule out incorrect password entry. This is a very big problem!

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?
