Since updating to the new Firefox 150.0 (aarch64) - two of our client's websites are having issues with too big/distorted logos (png files).

Sites are A-OK in Sarfari and Chrome.

solarisiaq.com

Remade the images and re-uploaded (thinking the files were corrupt). Did not fix the situation. Cleared every cache available (object, builder, browser, hosting).

Could there be an issues with the browser?

Hello, I have multiple devices using Firefox on the same network, and whenever using them at the same time, I get an additional Firefox icon in my doc which will open whatever tab is up on the other device. I was not signed in to any account on either device, yet it is still sharing tab data across devices.

I then created an account and signed in on one device and disabled every Sync option I could find, but still the sharing is enabled over local network. How do I disable this so there is no communication between the two devices?

Device 1 - MacBook Pro (Retina, 13-inch, Early 2015) macOS Monterey 12.7.6 Firefox Version 149.0.2

Device 2 - MacBook Pro 14-inch, 2023 macOS Sequoia 15.4.1 Firefox Version 149.0.2 Local Network access disabled for Firefox in macOS settings

It doesn't seem like this should even be possible given that local network access is disabled for the one device, and neither device is logged into a mozilla account.

Can someone please help me disable this functionality?

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

• Settings > General > Startup > Open previous windows and tabs > TRUE (checked)

macos 26.5 (25F71) Tahoe:

• Settings > Desktop and Dock > Mission Control:
• ---> Automatically rearrange Spaces based on most recent use: FALSE
• ---> ...switch to a Space with open windows for that application: TRUE
• ---> Group windows by application: TRUE
• ---> Displays have separate Spaces: TRUE
• Dock > Firefox application icon > [Right Click] > Options > Assign To > This Desktop (i.e., Desktop 3)
• Apple Menu > Shutdown > Reopen windows when logging in: FALSE

This is the message I get when trying to login to my Costco account: Application error: a client-side exception has occurred (see the browser console for more information).

Running on a Macbook with Tahoe OS. Certain websites will not display my responses to a checkmark box. Certain websites will not permit changing a checkbox default setting. Specific example: https://cards.barclaycardus.com/ has a checkbox with remember user name defaulted to a check. Attempts to click to remove the check do not work. Also, on certain websites when entering login information that is incorrect, the message indicating to correct the item(s) in red or highlighted does not display the incorrect items in a highlighted condition. In fact at the bottom of this page, the response box labeled Email me when someone answers the thread does not display a response when I click on it, even though the "response" is accepted.

i used to be able to access Gemini by clicking an icon in the leftmost column of any Firfox screen. I nw get an error 502 message. How can restore access to Gemini

I followed the instructions to set a security and there is no option to do it. I need to be able to login to all of my gmail accounts. The correct password was used, and is shown when I click the key icon and is accepted on other browsers. What is the problem and how do I fix it?

Whenever I try to watch videos on websites such as onlyfans youtube, etc., the videos will not play since I installed firefox. I have to shut my computer down and start it all up for them to play. I googled how to fix this and I need to go to settings and scroll to performance and uncheck use recommended performance settings and uncheck use hardware acceleration when available but I can't find this to uncheck these items. Can anybody help me? TIA

My System Administrator upgraded my Macbook Pro laptop after upgrading from Sequoia to to Tahoe version 26.4. This was a JAMF migration. The reinstalled Firefox does not show my bookmarks, after logging in to Firefox with my username and password. I tried to restore bookmarks but it loaded only a few, from more than a decade ago.

My problem may not be from the same cause, but I'm experiencing the same issue. Ever since my MacBook M3 Max updated to Tahoe, Firefox has been draining my battery incredibly fast. Before Tahoe, I could count on 8-9 hours of constant work with mixed use of higher processing work. Now, I'm lucky to get 4 hours of light browsing. Before I totally blame Apple, has anyone else experienced a recent shift?

Since latest update when trying to view pages with artwork on them I get a message that the page is slowing down Firefox and asks me if I want to stop the page to speed up the browser. I do not want to stop the page so I click the X, but Firefox refuses to load the pages at all anyway! I can no longer view many sites due to this issue. Please get rid of this awful code! Thanks.

It is very frustrating that Firefox consistently does not recognize my email sign-in. When I click on "other ways to sign in" and put in my password, it tells me I've done too many attempts and I have to jump through other hoops to get into my email, even if it's just one attempt.

I have a Macbook Air and I have Tahoe version 26.4.1

What do I do?

Hi and thank you... This is about issues going on Google and using a few websites.

I have a Macbook Pro 16" updated (OS Tahoe) and Firefox updated 140.9. The latest OS Tahoe was installed a few days ago. I use Firefox as my browser and don't wish to bounce around to Safari or Google Chrome, etc.. Firefox always works well but right now I have issues like getting onto Google as a search engine:

I have been getting issues about the same time with Google (keep getting the reCAPTCHA page see attached file.)

We get the caption missing on a news artcle when we first open up AOL and the news comes up.

My husband has some of his video music lessons in a website he goes to daily not opening up to the correct size.

My Safari page does not show the grid it used to with all my apps. Instead I get an Apple ad and have to work around it. So I am missing the Safari grid I used to have.

I have checked with Apple (3 times), Spectrum (internet connection but they did not give me a new IP address. I don't know if they can), I also Sent a message to Google forum and still Google says they are blocking me until I do a reCAPTCHA and the problem disappears so that is not helping yet. We have also connected my husband's website but they don't seem to help in this case. So it must be Firefox mozilla and Google does not seem to help except to tell us something is not working on our end.

Apple noted the latest OS tahoe could be such that, google, Firefox , etc..has not updated to match Apple updates but they do not know this for sure as they are not dealing with third party. Apple did not suggest that clearing history would necessarily help with this particular problem. I also don't have any VPN connections. Can you help? We are frustrated and the only real person I can talk to is Apple. Thank You if you can help Barbara Lipa

The new built in VPN is not showing up on my laptop browser. I have version 150 so it should be on there if I'm not mistaken. I can not find any way to get it to show up. It has shown up on my work computer so I know what it looks like and how to activate it when I see it.

My Macbook wasn't responding, so I restarted it and force quit all applications. When I opened Firefox again, none of my bookmarks showed on my bookmarks bar. The bar itself is not hidden. I checked to make sure I have the same profile I always use open and I do. I also tried to go into Bookmarks, Manage Bookmarks, Import, but nothing is available to import.
