Hi everyone, I manage https://myphoneoffers.com, a website that lists mobile phone prices and SIM packages in Bangladesh. I’ve noticed that a few JavaScript-based components (such as floating offer banners and comparison tables) don’t always load properly in Firefox. In some cases, it looks like ad-blocking or strict tracking protection might be preventing the scripts from running. I’m using lightweight JavaScript with no third-party ads — just local scripts and analytics. Could anyone explain how Firefox’s Enhanced Tracking Protection or JavaScript settings might affect embedded scripts? And what’s the best practice to make sure essential scripts still load while maintaining user privacy? Any insights from web developers familiar with Firefox’s JS behavior would be really helpful. Thanks!

Environment - Device: Acer Neo 16 (PHN16-71), 2023 model - OS: Windows 11 23H2 (Build 22631.4974) - Browser: Firefox ESR 128.7.0esr (similar issue observed on 140esr) - Current version in use: Firefox ESR 143.0.4 (64-bit) - Graphics: Hybrid – Intel UMA + NVIDIA RTX 4060 - Drivers:

 - Intel UMA: 31.0.101.4146 (UMA-labeled)  
 - NVIDIA: 551.76 (GeForce Game Ready Driver)

Issue Description While using Firefox ESR (128.7.0esr and 140esr), the laptop’s built-in screen occasionally begins to flicker, and after prolonged usage—especially when browsing Facebook for tens of minutes—it gradually develops severe distortion, resembling water damage or ripple effects.

Key observations: - Screenshots appear completely normal, indicating the framebuffer is unaffected. - No external monitor has been tested yet; the issue is only observed on the built-in panel. - Rebooting temporarily resolves the issue, but it recurs unpredictably. - This issue never occurred on my older laptop (Acer V3-772G) using the same ESR versions.

Steps to Reproduce 1. Launch Firefox ESR (128.7.0esr or 140esr) 2. Browse Facebook continuously for tens of minutes 3. Screen begins to flicker, then gradually distorts 4. Take a screenshot → image is normal 5. Reboot → screen returns to normal

✅ Expected Behavior The screen should remain visually stable during browser usage, without flickering or distortion.

Actual Behavior The built-in screen flickers and eventually distorts, while screenshots remain unaffected. This suggests the issue may lie in the final stage of the display output pipeline, possibly involving the TCON (Timing Controller) reacting to GPU output or Firefox’s rendering behavior.

Additional Notes  

- Hardware acceleration was disabled in Firefox for testing — the issue still occurred (on older versions). - No similar behavior observed in Chrome or Edge. - BIOS screen appears normal, ruling out panel damage. - After upgrading to Firefox ESR 143.0.4 (64-bit), the distortion issue has not reappeared for two weeks, though minor flickering still occurs occasionally during browsing. - Interestingly, when distortion or flickering occurs while browsing Facebook, switching to another website immediately causes the screen to temporarily return to normal.

 This suggests the issue may be triggered by specific rendering patterns or GPU calls on certain web pages.

- This may indicate a rare interaction between Firefox ESR and specific hardware configurations (UMA → TCON → panel).

I generally always use Firefox on my PC for everything.

I also often chat with Amazon as they are never short when it comes to fucking my orders

I have not used Amazon for the past 2-3 months and when I finally placed a new order 3 days ago, to resolve the usual non delivery issue, I contacted them via Live Chat, however instead of seeing Chat window pop open as usual, all I got was ABOUT:BLANK in new tab, hmmm...

So far to fix this or at least ascertain cause:

- I contacted Amazon.fr (where I live) and guy at digital services said, "nah, no flies on us, it's Mozilla's fault" - Edge, on same PC (windows 10), works OK for chat - Launching in safe mode changes nothing - Nor does disabling NordVPN - I also added Amazon.fr as "exception" in pop-ups, to no avail - and when I unchecked block box to enable all pop-ups, no better luck - lastly, on my iphone via Safari, all is good, assuming one enjoys typing with 1-2 fingers

my version of Firefox is up to date: 144.0.2

voilà

suggestions?

thanks

Hello Firefox Community,

I’m facing an issue with my restaurant-related website Bojangles Menu with Prices—https://bojanglesmenuprices.us. .

When I search for my website in Firefox or share one of its pages through the browser (for example, by copying the link or sharing via email/social media), the preview doesn’t display correctly. Sometimes the image thumbnail is missing, and other times the meta title or description doesn’t appear.

Here’s what I’ve already tried:

Checked the Open Graph (OG) and meta tags on my site.

Cleared Firefox cache and cookies.

Verified that the site preview works fine on Chrome and Edge.

Updated all social and sharing metadata in my HTML.

Is there any Firefox-specific issue or setting that could affect how link previews or shared content are displayed? I’d really appreciate any help on how to make my Bojangles Menu website show up correctly when searched or shared via Firefox.

Thank you! Sonia

Hi everyone, I run a website, which provides information about mobile phone prices and SIM packages in Bangladesh. I’ve been working on improving page load speed using LiteSpeed Cache and Cloudflare CDN. While it works well in Chrome, I’ve noticed that Firefox doesn’t always cache pages or static assets (like images and CSS) as effectively. Does Firefox handle cache-control headers or service workers differently than other browsers? I’d also love any advice on best practices for implementing browser caching or service worker scripts that improve performance on Firefox without causing outdated content issues. Thanks for your time and any insights!
