This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

https://appointment.questdiagnostics.com/schedule-appointment/as-personal-information

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

Hi, y'all, I used to use the weather on new tab feature a lot until the latest update seems to have taken that feature away? Is this intentional or am I missing something? Here is an example of what it looks like: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_weather

Some troubleshooting I've tried so far:

• I clicked the gear icon to go to settings, but there is no settings for weather anymore.
• I turned off my VPN, because I heard it was available to U.S. and Canada users only, I am in the U.S.
• I closed firefox and reloaded.

Any tips/help is appreciated.

Hi, Up to the most recent update of Firefox I could preview PDFs within a cloud based software, but when I downloaded them they opened up in my default PDF Viewer.

Since the update the preview PDFs in the software just spin and never show, unless I have the setting in Firefox set to "open in Firefox" then I can see them. But if I have that set, then any PDF I try to open or download will open in a new Tab in Firefox, rather than the PDF viewer, and then I have to save it to be able to open it in the PDF viewer.

However, if I change the setting to be "Use Windows Default Application" they open up just fine in the PDF viewer, but the previews in the cloud based software go back to spinning and not opening.

How do I get back to having both things happen, rather than either / or please?

Many thanks for any help offered Best regards Jen

I've noticed that HDR content on YouTube plays at apparently maximum brightness, which is overwhelming. The same video using Google Chrome behaves as expected. For example:

https://www.youtube.com/watch?v=Xod2xiLA9CM

I'm running FF v135.0 and Chrome v133.0.6943.54. When using Chrome, the video brightness matches system brightness settings on my Macbook Pro (running Sequoia 15.3) but when I use FF, the video itself is incredibly bright, as if the white levels have been maxed out. It seems to be a problem with handling the HDR content. Even stranger, it's as if the browser is able to increase my screen brightness itself, but only in the video pane. I doubt that's actually happening, but that's what appears to happen. If I switch to another tab and then back to the video, it takes a few seconds for the video pane to increase extreme levels.

Also, I tried to take a screenshot of it but the screenshot doesn't show the extreme bright levels that I see when I'm using the browser.

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

a few months ago firefox started rendering images funky. I am not sure what changed, it seems to be a setting problem as other computers with FF 135 don't seem to do this. I have not been able to come up with the right search terms to describe the problem. here is a screen shot of the issue.

i am running windows 11

after windows updates, my firefox will open but the search bar does not open and i cannot use it

i uninstalled and reinstalled firefox

i went to settings to make it my default browser

no help

Long story short (as possible):

Windows 11 Home, Firefox version 135.0, File version 18.5.0.0, Product version 18.05

Opened Firefox first thing as soon as PC was turned on today. Immediately prompted for an update. It's Mozilla/Firefox. I didn't question it. I did the update and it asked me to download a file. "I trust Mozilla. OK". It downloaded a Firefox Installer.exe file. The same as the one I installed back in 2022 when I set up this PC. I noticed it was a duplicate because (1) followed the file name. "Odd, but okay...it's Mozilla/Firefox. I trust it"

Then I tried to use Firefox and no matter what website I tried to go to I got a "Gah. Your tab just crashed" on the page. It had "Restore crashed tabs" options but nothing worked. All led back to "Gah. Your tabs..." Thinking about the same Installer.exe file and its (1), I checked the Firefox update history. Nothing for today. I then opened the Properties of the original 2022 Installer.exe and the one today. All were the same except 1) - the 2022 file is 325KB and the (1) file from today is 364KB, and 2) - under Digital Signatures, the Digest algorithm is "sha1" in the 2022 file and "sha256" in the (2) file from today.

I didn't know this Ask a question/forum was here or I would have inquired here first. Instead I turned to Reddit's Firefox group using my phone before I did anything on my PC. I spec'd out the details of the day and was assured by two people to do a restart of Firefox. So I did. Yup, that seemed to fix the issue. And off I went with the stuff I'd originally had in store for my day. Until I had different/unrelated need to view my Downloads and I see a FireFox Installer(2) that must have crept in when I did the restart. There was no notification/prompt or request to allow. It just showed up and I wouldn't have known about it unless I checked my Downloads folder.

Until someone tells me otherwise, I'm staying off Firefox. Two .exe Installer files downloaded for a simple update? One which I authorized/allowed but the other sneaking in when I restarted Firefox? Not to mention the tabs not loading until I did the restart which if legit needed, Firefox didn't prompt me to do? That doesn't sound like normal Mozilla/Firefox behaviour. None of today's events do.

So...is this fishy like I think it is? Fishy or not, what's the best thing to do? I'm okay with computers but DEFINITELY NOT an expert. Hence me being here and asking what to do. Guidance needed. Help?

I wrote out the OS details and specs of the browser. I think that's all that anyone would need but if I'm wrong, don't hesitate to ask for more.

Thanks folks.

I could play Zynga poker yesterday. but today I get this message.Having issues? Try the following troubleshoot tips:

Enable WebGL:

  Type about:config into the address bar and press ENTER
  Search for webgl.disabled compatibility
  Ensure that its value is false (any changes take effect immediately without relaunching Firefox) 

I checked setting was false.

Having succesfully updated to the latest version of Firefox on a Linux System, how can I make this version my default browser? When I click on the icon in the panel (bottom of screen) it launches the old version, but if I click on a link in an email it launches the new version.
