Using the browser Firefox when Claude is answering questions every 3-4 responses will hang and the response will consume up to 98% of the cpu as well as 600 to 700 MB of memory. The only recovery is to kill the tab. The CPU is : Intel(R) Core(TM) Ultra 9 185H 3.10 GHz With 64GB ram Using Firefox version 139.0.1 I had Claude switch to only respond with plain text and the issue continued. The issue also occurred during a discussion with Claude about this issue which confirmed it was a Firefox-specific problem with Claude's interface. It during his response, it's likely related to the real-time text streaming or DOM updates.

We use an external system for our general day to day business, which has links on the customer details for email. This launches Thunderbird, and puts the email add. in the to field. Is there a way I can get thunderbird to use a template when it receives this command from the external program? The address changes each time, but I want to use the same template to speed up a process.

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

hi Firefox 115.24.0esr (64-bit) do not allow my see this website .But Chrome works good.

Code 500 UPSSS! An error occurred while loading the page. Make sure you are connected to the internet and try again.

How to fix this .

I am having a problem with FireFox: using DuckDuckGo as a search engine I only get a white page with a search window at the top as a result. DuckDuckGo works fine in Safari as I am typing this. Other search engines work fine in FireFox.

I have tried running FireFox in troubleshoot mode and then manually disabling extensions one by one but the issue persists. It makes no difference whether I am using the URL box, the search box or the DuckDuckGo website: the result is always the same. I am not using Metamask and I have no VPN installed.

Any idea is greatly appreciated.

when I play a product video on amazon, I get the following error. I don't have a problem with another browser.

The media playback was aborted due to a corruption problem or because the media used features your browser did not support. this is a linux mint desktop.

thanks.

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

The "import bookmarks" doesn't work on my ubuntu 24.04.2 LTS running on an old macbook air. I exported bookmarks from my chrome. when i try the import from file, it says "bookmarks exported successfully", but the bookmarks don't show up anywhere. attached screenshots. what am i missing? thanks, Nilesh

I'm looking for a solution to an annoying bug in Firefox on Windows 11. The taskbar won't hide when I go into fullscreen on videos (e.g. YouTube).

The issue is directly tied to hardware acceleration.

This doesn't happen in Chrome, and I've already tried reinstalling Firefox and updating all my drivers and Windows. Does anyone know of a fix for this bug?

Hello, after the most recent Firefox update, and it doesn't happen with every web page but it seems to be most frequent on ones I have never visited, that I get a tab that says "Gah! Your tab just crashed". If I close the browser and reopen it, then reload the crashed tab from my recent History, it seems to work. Anyone else experiencing this (Win 10 Pro 64x desktop PC)?

First symptom: Lately, when I use Firefox on my desktop to attach a JPG or PNG screenshot to an online post, it shows up only as a black square. (The image looks normal while I'm creating the post, but it won't post - which I've confirmed by checking my feed on a different device.) This doesn't happen when I use the same version of Firefox (the latest one), also running Windows 10, on my laptop. It has nothing to do with the screenshot itself - the specific file or the file type; the same thing happens with anything I try to attach.

Second symptom: When I create a PDF with Firefox and then try to print it, a large rectangular portion at the top is blanked out, as if someone had placed a sheet of paper on top of it. This doesn't happen when I use Chrome to open and print the same document on the same computer.

My guess is that I've somehow changed one of the graphics or image settings in about:config, but I have no idea which one.

Any ideas would be greatly appreciated.

A few weeks ago I tried installing a Pi-Hole (hardware-based network level ad blocker), removed it shortly thereafter. Since then, I've been getting the "Our systems have detected unusual traffic from your computer network" screen whenever performing a Google search from Firefox in Private mode, either from the toolbar or from the website. It only happens on Firefox (nothing from Chrome incognito windows), only happens in Private windows, and recurs every hour or so within the same open private window.

I've tried everything to reset my system to baseline to root out the issue, but I'm getting nowhere. Things that haven't worked:

• setting all VPN and proxy settings to off
• ensured all DNS settings are set to automatic
• renewing IP (IPv4 and IPv6, via command window and leaving router/modem unplugged overnight and verifying new dynamic IP assigned)
• clearing all browser data (cache, history, cookies)
• disabling all extensions (Ad Block Plus is my only extension)
• refreshing Firefox (about:support > refresh Firefox...)
• hard router reset
• different network device
• multiple malware scans (all clean)

Is there anything specific to Firefox and how it handles Private connections that might be throwing a wrench here? I'm pulling my hair out.

I created a tab group and saved it. After saving I confirmed it was inn the toolbar location. I used it this morning successfully. Just now I closed all my tabs in order to shut down. Doing so eliminated the tab group. It is no longer available from the toolbar. What happened?

Sucessfully installed Firefox 139.0.3 armv7 nodpi on an Android 5.1 tablet device, but no matter what website I try to access (even Google), a plain black screen is always displayed. Homepage and Settings page works fine, even those history thumbnails are showing the website correctly. If I click on the address bar to type something, it then suddenly changes from black to the actual website for a blink of a second and then gets black again.

Is there a way to fix this? Firefox Focus, Beta and Nightly behaviors the same. I already tried to uninstall and clearing data/cache. It seems a bug with this specific tablet device I am using even though it shouldn't, since Android 5.1 is still supported, isn't?
