Issue: Critical Rendering Failure and Script Latency on Polybuzz.ai I am reporting a consistent issue where modern AI platforms, specifically Polybuzz.ai, fail to function correctly on Firefox (both Android and Linux). Despite being a loyal user since 2004, the current performance gap compared to Chromium browsers is making daily tasks impossible. Core Technical Problems: Layout Corruption: Even in Desktop Mode, the UI breaks, elements overlap, and CSS grids do not render properly. High Input Lag: Massive delays in JavaScript execution, causing the browser to become unresponsive during site interaction. Engine-Level Issues: The problem persists on both Android (latest stable) and Linux (Zorin OS/Linux Mint), suggesting a fundamental issue with the Gecko engine's handling of heavy AI frameworks. Troubleshooting Done: Tested with Enhanced Tracking Protection both ON (Standard) and OFF. Cleared all site data and cache. Verified that the same site runs smoothly on Chromium-based browsers on the same network/device. Please investigate Gecko’s compatibility with these modern web standards. Screenshots of the broken UI are attached for reference.

I set up a new account last week and need instructions on how to navigate and use this forum. I cannot find the question I posted. I got no email saying it was answered. I also need information about these codes I keep getting in my inbox after I've already logged in. I don't know what to do with them. I'm a newbie and need an instruction pdf if there is one. Thanks.

I assume Mozilla developers are working on this?

Quote from the article

"Its capabilities are a step change from the previous best models. Given the challenge of attacking the Firefox web browser’s JavaScript engine, Anthropic’s previous most powerful model Opus 4.6 succeeded just twice, compared to 181 times for Mythos. Most worryingly, the team found that engineers with no security background could use it to develop successful attacks overnight."

Installing the latest version of Firefox and Debian 13.

Following the instructions in the Mozilla Support document Install Firefox on Linux https://support.mozilla.org/en-US/kb/install-firefox-linux

Operating as Super User.

Chose the option Install Firefox .deb package for Debian-based distributions (recommended)

Steps 1, 2, and 3 worked exactly as expected with in a terminal and using bash.

Step 4 and 5, following the For Debian Trixie and Newer choice does not work. A lot of digging on the internet and found that the command beginning with cat <<eof needs to be cat <<’eof’. the second part of this process has same issue. appling new information solved problem both statements now work. < p></eof>

At this point you have a directory /etc/apt/keyrings. In this directory you have the file packages.mozilla.org.asc Step 3 returns success. You have also successfully applied steps 4 and 5. In directory /etc/apr/souces.list.d you have the file mozilla.sources.

It contains the instruction “Signed-By: /usr/share/keyrings/packages.mozilla.org.gpg”

No where in the previous stepd was the file Signed-By: packages.mozilla.org.gpg ever created.

Why is the deb package looking in /usr/share/keyrings when step 2 puts a similarly named file Signed-By: /usr/share/keyrings/packages.mozilla.org.asc in /etc/apt/keyrings

Step 6

Running apt update returns

Err:4 https://packages.mozilla.org/apt mozilla InRelease  Sub-process /usr/bin/sqv returned an error code (1), error message is: Error: Failed to parse keyr ing "/usr/share/keyrings/packages.mozilla.org.gpg"  Caused by:     0: Reading "/usr/share/keyrings/p ackages.mozilla.org.gpg": No such file or directory (os error 2)     1: No such file or directory (o s error 2) Warning: OpenPGP signature verification failed: https://packages.mozilla.org/apt mozilla InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Error: Failed to parse keyrin g "/usr/share/keyrings/packages.mozilla.org.gpg"  Caused by:     0: Reading "/usr/share/keyrings/pac kages.mozilla.org.gpg": No such file or directory (os error 2)     1: No such file or directory (os error 2) Error: The repository 'https://packages.mozilla.org/apt mozilla InRelease' is not signed.

Hi. Since the Thunderbird update in March/2026, my Bell sympatico.ca email is no longer able to send emails out through Thunderbird. No error messages but emails never get to destination (I tried sending to myself on both gmail and sympatico accounts). I receive emails without issue. I tested the sympatico from the web or my iPhone and it works. Seems something changed in T-bird back in March?

I validated the Outgoing SMTP server settings and all seems OK (See attached file for screenshot of settings). Any idea why and what changed to cause this?

Tx, Robert Ziwani

I've been trying to connect for over an hour and I always get the answer; " Connection to the server impossible. The configuration, username or password are probably incorrect. My access provider is “Orange” and I made the mistake of accepting “Unlimited Emails”, I have 650,000… I work on a MacBook Pro Apple M1 Pro 26.3.1 (a) and the Mail app is very saturated and Tchat Gpt advised me to use your “Thunderbird” app I changed my Orange access password about 4 hours ago. Please guide me towards making your application work properly.

Yesterday, I had a trusted Firefox browser with bookmarks going back many years. Today, I have a Firefox browser which has zero bookmarks and no import capabilities. For the first time since Firefox, Edge is starting to look better.

I'm signed in on both the mobile and desktop app with the same account, sync is on for both of these, but the sync is not actually happening. None of my passwords or history is accessible in the mobile app. It also seems to not save any history at all because I keep having to type in whole web addresses instead of the app filling in the rest itself, even though I've visited these websites many times. There's no error in the settings or anything, it's just not working properly.

I am not a computer nerd I can only describe what is happening. I am addicted to puzzles and do them every day but am encountering problems nearly every day this week of the puzzle pieces not responding to mouse and have to shut down the computer. At other times I am kicked out of the site and returned to my desk top. No amount of trying to then get back into firefox is useless until much later on. Why is this happening?

Les liens dans les collections sont trop trop sensibles à l'effacement sur mon mobile Samsung A25 5G. Je perd facilement les liens en navigant d'un lien à l'autre.

I've turned all Search SETTINGS to OFF. The Firefox Suggestion show up as soon as ANY characters are entered into the browser's search box.

According to the help pages, I should see Firefox Updates in the General section of the Settings tab. I found this out because Firefox is not being covered by my (independent) tracker protection programme. The fix, according to the independent tracker, involves accessing the 'Firefox Updates'
