Hello,

I am reporting a performance issue specifically related to Google Search's AI features (AI Overviews) in Firefox 149.0.2 on macOS.

The Issue: When an AI-generated summary appears in Google Search results, GPU usage spikes significantly, reaching up to 212%. This causes the laptop to overheat and triggers high fan speeds.

Critical Comparison:

Firefox 149.0.2: Extreme GPU load and performance degradation when rendering Google AI elements.

Google Chrome 147.0.7727.56: Works perfectly with normal GPU usage under the same conditions.

Tested on two different MacBooks: MacBook Pro (A1502), 16GB RAM, i7 (2015) — OS: macOS Monterey. MacBook Pro (MMQX3), 64GB RAM, M1 Max (2021) — OS: macOS Sequoia (15.x/Tahoe).

I'm trying to e-file and can't because I'm being told the following: To display this page. Firefox must send information that will repeat any action (such as a search or order confirmation that was performed earlier

This website isn't working: "https://account.iheart.com/login/?redirectUrl=https%3A%2F%2Frealradio.iheart.com%2F". I am using FlashPeak Slim Browser, which uses Firefox.

Since last update...the reaction emojis on Facebook are blacked out. The entire bar of emojis are not visible. It is all black. Yet the words are visible when hovered over. There seems to be nothing wrong with the FB site and it has been suggested it could be the browser. So if you have any reports of glitches like this ...would be nice if you could fix. Screenshot Impossible to take. Thanks

cut and paste not working on one box on ebay listing page!

ebay sell an item. opened page appears with boxes of which one is called description. This week, the cut and paste will no longer work on that box. It works on every other box on that page! Ebay say its not them.

Firefox Image Display Problem with Grok / xAI ChatI'm using:Dell computer Windows 10 Firefox (latest version)

Problem: Grok-generated images (graphs, memes, translated election charts, etc.) do not appear at all in the chat. I only see blank spaces or broken image icons. Right-click → "Open Image in New Tab" and Ctrl+Shift+R (hard refresh) do not work.This issue started during a long conversation where Grok was creating multiple JPG versions of an election results graph with translated text.Note: The same images load fine in other sessions/browsers, but I prefer to stay with Firefox. Is this a known compatibility issue with Grok's image rendering system in Firefox? Any settings, extensions, or workarounds (without switching to Chrome or Edge) that can fix it?

Just started getting messages when I log into Schwab that my browser, Firefox 115.36 esr, is not fully compatible and that I may see some performance issues. Yes I do see issues such as misshapen popup windows when buying/selling shares.

i have tried to login via your mizilla browser, but not logged in. also when i am trying to browse linkedin and other websites, the web page not opening at first time, i am suffering in problem, but in my laptop i have other 3 browser, chrome, edge, brave, they work correctly and smoothly in the websites and all sites. only problem .

For the past few days when trying to use Google search on Firefox I get this message:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?"

Then it makes me jump through several hoops to do a search on google.

This is a Firefox specific message as I can switch to Safari and there is no roadblock.

Is this happening to anyone else?

Any way to resolve?

Why this is a Firefox issue and not other browsers?

certain sites ( like FedEx tracking ) say that I can't visit because my browser needs an update. but I checked and Mozilla says that I AM up to date . last update April 28 What can I do to fix this?

After successfully using an AI image generation site (OpenArt.ai) for numerous months, I suddenly stopped being able to successfully upload images from my local hard drive into its image editor. All attempts created an "NetworkError when attempting to fetch resource (storage.googleapis.com)" error. I had made no changes to settings or permissions of any kind, but out of nowhere I cannot use function of that website through Firefox. Onlines searches suggested setting up a local network with Python, which is not something I'm familiar with, or that there were browser extensions identified as "Web Server for Chrome" the "Local File System" extensions, neither of which seemed to come up in browser extension searches through Firefox using those terms. Anybody got a fix easy enough to be walked through without learning new software?

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

I sometimes sell items on sites such as eBay. When I try to copy and paste the picture (from my Photos) is just a weird symbol. If I go to a different computer it works! If I go to a different browser it works! When I open a weather App the radar is all washed out with different colors. What's the issue?

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.
