Firefox Community Forum

In Firefox Desktop 151.0 Beta 1, I'm experiencing a severe DNS leak even with DNS-over-HTTPS (DoH) set to "Max Protection". I've tried all available troubleshooting steps (including resetting `network.trr.*` preferences, disabling extensions, and testing in a clean profile), but the issue persists. > The same configuration works correctly in the previous version (150.x). Has anyone else encountered this regression?

"I am a dedicated open-source supporter who has helped 19 new users switch to Zorin OS and Firefox to ensure their privacy. Recently, on the official Zorin OS forum, I was silenced and threatened with a ban by a 'Community Leader' for defending Firefox's Gecko engine.

They accused me of 'advertising' and 'spamming' simply because I shared how many people I’ve converted to Firefox to show the impact of digital freedom. I am reporting this because it’s discouraging to see major Linux communities treat Firefox supporters as spammers. I hope Mozilla looks into how their advocates are being treated in other OS ecosystems."

Using Firefox browser 126.0.1 via Steam Deck desktop running SteamOS 3.6.22; I am unable to download any extensions. I tried to download uBlock Origin and ProtonVPN through addons.mozilla.org, but recieved an error message:

"Installation aborted because the add-onn appears to be corrupt."

I then checked other extensions I found on the front page recommendations, like "Dark Reader" and "Image Search Options" and they gave me the same error.

Could not find anything that helped my situation upon searching for solutions, any help would be appreciated.

I reported an issue with Firefox 143.0.2 where History would not stay deleted. Same problem as reported by Bojan Nesic 5days ago. It looks like the bug is fixed/closed. (Sorry- this is first time I've reported a bug). I updated to 143.0.3 but bug remains. Is there another update? Thanks

What is the cause and remediation of my constant Firefox notification about the geolocation database being updated?

Firefox 16:35

"Geolocation databases updated

The IP geolocation databases were successfully updated in 2 seconds.

I use Nordpass password manager. If I try and open a site from Nordpass , Firefox Relay overlays the page , preventing the use of Nordpass. How can I disable this Firefox Relay?

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

After entering verification code from email i receive an error every time i try to login into this account on my PC, i fully cleared browser data several times but it didn't help

Hello,

I am experiencing a recurring issue with Firefox on Kali Linux.

Environment:

- OS: Kali Linux (running inside Termux on Android) - Connection: VNC (RealVNC) - Device: Android phone (low RAM) - Desktop: XFCE

Problem: Whenever I open Firefox, tabs frequently crash with the message: “Gah. Your tab just crashed.”

What I already tried:

- Disabled hardware acceleration - Disabled recommended performance settings - Ran Firefox in safe mode - Created a new Firefox profile - Lowered VNC resolution - Restarted the system

The problem still persists.

I believe this may be related to graphics rendering or memory limitations under VNC/Termux.

Please advise if there is a workaround or configuration that can prevent this crash.

Thank you for your support.
