AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

suddenly today the mic has stopped working in Chat GPT. I have changed nothing... checked all settings, everything is ok... why does it suddenly say "Enable Mic Access to Dictate"?

Im using Windows 10 Pro 64 bit on a Asus laptop with 32GB RAM in it and a i9-9980HK @ 2.40GHz. It has a GeForce RTX 2060 graphics card in it with 6GB memory. I use it for work and need to have multiple tabs open at a time as a result. I always have at least 4 tabs and can sometimes get up to around 10. I also have Zoom running as well.

I keep seeing a ton of Firefox processes open when I look at Task Manager. Attached is a screenshot I just took with 7 tabs open. It shows 34 processes in the first clump with more open outside of that one.

I unchecked Use recommended performance settings and checked Use hardware acceleration when available but all that did is lower the amount of RAM being used by 100MB. I have 2 extensions enabled in Firefox, AdBlocker for YouTube and AdBlocker Ultimate. They have never been a problem before. This lag and massive overusage of RAM has only started in the last couple of weeks.

Anyone know why this is happening or how to reduce how much RAM Firefox is using? I like this browser and would have to have to switch to another one. Thanks in advance.

Since the update to 142, on pretty much every site it keeps jumping back to the top of the page. Happens on a lot of sites. For some reason, if I select some text at the top of the page it seems to stop this. A lot of people may not have discovered this. Mozilla just needs to fix it. I am using Ubuntu 24.04. Been using Firefox for many years. Never seen this before.

How to disable the auto-adding of shortcuts feature from history to home page? It's really annoying, when I want to change my pinned shortcuts, I have to delete all auto added shorcuts (Even when the items on the screen are finished, they keep appearing in front of me, and this takes a long time). It is a must feature I think.

Many web pages that have a video header will launch the video in a popup window after you scroll past the header.

There are no user controls in the popup window, and clicking 'block popups' and turning off 'enable p-n-p controls' had no effect on them.

Is there a a setting that will stop these video popups from automatically launching? They eat up a lot of memory, and are a pain to turn off manually.

Thanks.

I am trying to set up a new computer. I have customized the homepage and new windows to a preferred page, however I cannot customize the new tab settings. The only options for a new tab are either Firefox homepage or blank page. I am trying to find a way to have my preferred homepage open when I open a new tab.

Description: We have encountered a significant performance issue with NativeMessaging API in Firefox when an extension communicates with a native application.

In scenarios where many objects must be enumerated (e.g., ~458 certificates), Firefox is dozens of times slower than Chromium-based browsers.

Environment:

Firefox (latest stable, reproduced in 2025)

Windows 11 x64

Same machine and same native plugin tested in Chrome, Edge, Yandex Browser

Steps to Reproduce:

Create a WebExtension that communicates with a native application via NativeMessaging.

Perform enumeration of a large number of objects (≈ 450–500).

Measure execution time in Firefox vs Chromium.

Actual results:

Firefox: enumeration of 458 objects takes ~2 min 30 sec

Chromium/Edge/Yandex Browser: enumeration of the same 458 objects takes ~5 sec

Additional tests: Round-trip time (RTT) for a single message:

Firefox: ~73.7 ms

Chromium: ~0.3 ms

Because the extension and the plugin exchange a large number of messages, this performance gap becomes critical.

Expected results: NativeMessaging API in Firefox should perform at a level comparable to Chromium browsers, so that extensions relying on heavy message exchange remain usable.

References: Bug 1288912 – Native messaging performance is extremely poor

Although this bug is marked as resolved, performance testing still shows a major discrepancy in the current versions of Firefox.

Question: Is there any ongoing work or plan to optimize the implementation of NativeMessaging API in Firefox to address this performance issue?

Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.
