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.

On many pages which require a captcha to proceed, the button to proceed is non-responsive. In more polite pages, I get a message e.g. "couldn't confirm captcha". Why does this happen and how can I get around it??? Tnx, Nir

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.

Since the update to 135.0 64bit when I open a new tab and try to search something in the search bar, nothing happens. I have to type in a full website URL.

When I go into Settings, Search, the Default Search Engine dropdown is blank and when I click it nothing shows up.

File type-Action settings: For PDFs, the save and ask actions result in a spinning wheel & no other result. Seems to have happened recently, either with latest Firefox or the latest Mac OS update.

When i start Firefox, Avast reports a 'threat secured'. Something is trying to connect to 'addons.mysafe-search.net. I also have a problem whenever i receive an update for firefox, my system has a freeze and needs to be force quit and restarted, sometimes more than once.

About 3 days ago, none of my passwords are being saved in Firefox. Several times a day I have to put in my username and password for various sites, even if I don't shut down my computer. I have save passwords selected in my security settings in Firefox, but still does not save. This all started when I went into my Firefox settings 3 days ago to clear the cache, and that's when it started not to save passwords.

Mac mini late 2012 running OS 10.15.7 Downloaded most recent Firefox update (135.0). Since then have experienced streaming site (Netflix, Amazon Prime Video, Max) freezing during watching film and then whole computer freezing and crashing so that I need to reboot the computer. Has anyone else reported this problem? What can I do to solve the problem?

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

Firefox is not allowing me to save bookmarks into my toolbar folders. Is there a limit as to how many can be saved into a toolbar folder? This has been going on for over a month now. I use a VPN. Is the VPN causing an issue?

Every time I start Firefox after closing it, I get a screen saying "Your Firefox has been updated" plus an announcement about editing PDFs in Firefox. My degault home screen does not appear unless I click the "home" icon. This is frustrating, because the update message just won't go away.

The URL for that irritating message is: https://www.mozilla.org/en-US/firefox/135.0/whatsnew/?oldversion=134.0.2&utm_medium=firefox-desktop&utm_source=update&utm_campaign=135

I've attached a screenshot to show this, hoping you can suggest a way to fix the issue.

Hi, I have used Firefox regularly for years to login to my sjsu university account (google workspace) with the DUO security software. But for several days now I have been unable to login: I get "Unable to sign in" error message. At first I thought the system was down, but it's been days now and I can use other browsers to login just fine. I have cleared my cache completely and restarted the computer several times (Dell XPS laptop with Win10). Even weirder, I can login fine with Firefox on my other PC laptop (Win 11).

Can you please help?

I have used Firefox as my primary browser for many years, and have always used autofill for my passwords, credit cards, and addresses. Suddenly, about two weeks ago, my credit card data stopped autofilling. When I go to Settings > Privacy & Security, there is nothing regarding autofill anywhere (or anywhere in any Settings). I have attached screenshots of my entire Provacy & Security page, as well as Settings searches for "autofill," "payment," and "credit card." Please help me figure this out ASAP, or I will have to switch to Safari as my primary browser, which I don't want to do. Thank you!
