Firefox Community Forum

Moved from Windows to Mac and now facing this issue, so it seems to be a Firefox + Mac OS compatibility issue.

Have turned on screen recording permissions in Mac settings and some other accessibility permissions that have been suggested and nothing helps.

Will need to use a different browser just to screen share.

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).

Just the last couple of days I can no longer browse through the images of an ebay item. the first image loads but the arrows or the thumbnails yield no movement, and I can't use the contact seller button either. No other website is effected, I am using the latest Firefox with Ventura on an imac. It all works if I use Duck duck and go? All very strange. Tim

Recently the MS Q&A site displays outrageously small text. FF is fully updated as is Sequoia. I don't have the same problem when accessing the same site in Safari. I have tries various setting combinations in FF Preferences for Zoom & Font [including Advanced] but nothing provides a remedy. I really don't want to stop using FF but this is unbearable... I spend much time in Q&A supporting MS product. The image on the left ia how FF displays the page, the image on the right is from Safari.

I don't understand the reason Firefox is slowing down and making my emojis and GIFs on LinkedIn very difficult to access. This isn't a problem on other sites. Any solutions? Thank you for your consideration. marlem388

I have an Illustrator file save on Adobe's Creative Cloud. Tried to open it from Illustrator today and got this message (attached). I won't have any Google products on my computer and I'm not totally sure about how much MS Edge would follow me.

Can't figure out why Illustrator wouldn't open or download an Illustrator file. Or why Adobe would direct me to Chrome or Edge.

Not just Adobe products though - my local grocery store wants me to use Chrome to order groceries online.

What's up all of a sudden? Is it the new update??

My instagram does not open on my firefox browser. I have cleard all the cookies and cashes. I tried Incongnito, hot spot sharing. I have tried everything its still not working. Can you help me?

Running Firefox 149.0.2 (64-bit) on MacBook Pro (16-inch, 2019) with Catalina (10.15.9).

I was in the process of updating a non-profit's website and had opened the html file on my computer. I noticed that the "y" (lower case) was missing from the days of the week. I checked the RUNNING website and saw the same thing. Checked he same website with Safari and the "y" suddenly appeared. Okay, so I then tried to add another "y" somewhere else on that page and ... nothing, so on a whim I added a "Y" to my Mac's file and guess what? It upper case Y displayed. Also noticed that on some web pages instead of showing me the characters in some words, it substitutes "ddddddd" for some words. What's up?

Ever since the last update, I haven't been able to log into my yahoo account. I am able to access the account through other browsers and on my phone but not on my laptop.

All of a sudden, I cannot open my Comcast Xfinity email. After putting in my email address, I get an "access denied" message that reads: You don't have permission to access "http://login.xfinity.com/login on this server" Reference #18.8809c617.1777556475.511db42 https;//errors.edgesuite.net/18.8809c617.1777556475.511db42

I don't have the issue using Safari or Chrome. I have never had the issue with irefox until now.

Many URLs and hosts automatically reload pages. For example, when I am reading a multi-page article and am several pages in, the page often reloads and I have to start all over again and try find the place where I left off reading. "Stop Auto Reload" is a Firefox extension that is supposed to allow the user to stop the auto-reloading that many URLs and hosts execute, but it does not always work. It seems to work on some sites, but not on others. I have not found any other extensions so far that address this. Any assistance with this problem is greatly appreciated. -Neil

I can't sign into my RBS Digital Banking page using Firefox. The display flips back and forth uncontrollably from Login page to Are You still Here? page. Login via Safari is as normal .. but Firefox is my preferred browser.
