While playing chess at lichess.org, browser power management inhibit messaging to the system gets stuck on its current status. That is, if power management is inhibited by media playing on another tab while I play a game, it will get stuck in the inhibited state. If power management is uninhibited while I play (no media playing), it will get stuck in the uninhibited state. This persists until the browser is restarted even if all tabs are closed.

I don't believe it to be a system issue, as the problem clears as soon as the browser is closed. Chrome based browsers do not exhibit the behavior for me, but I tried a Firefox fork (LibreWolf) and it has the same issue. I don't experience this issue at any other website I visit.

Only certain areas of lichess.org cause this behavior, primarily playing a game against a human opponent. I tried progressively blocking media and script requests to narrow down offenders, but I always break site functionality before I can pinpoint anything.

I'm not so much looking for a solution (although that would be great) as I am troubleshooting advice. Is there any way to narrow down exactly what it is about this specific website that is causing the issue?

How do you avoid/deal with Firefox website incompatibilities? This happened on consecutive visits to two different websites today before I posted here.

In the first one, I disabled Ublock, cleared cache and cookies, and the site loaded, I then enabled Ublock with no error prompted.

Then I got a tab crash on Youtube. I wouldn't call tab crashes a daily occurrence for me, but I'm accustomed to them

Gmail tab crash just now. It just happened now with another website tab crash. i'm reverting back to 147.01

Is there any way to get the root of this. The only recent changes I can think of are browser (147.0.2 yesterday) and addon updates. Should I post my list of addons?

Dans free.tv pourquoi la suppression des sous-titres ne fonctionne pas problème Mozilla ou Free.tv ?

There was nothing wrong everything was running perfect and smooth but then out of nowhere my youtube froze and I couldn't press anything on youtube tab, I could still close it or press the buttons on the sides/corners but on the youtube, it also doesn't refresh, this only happens on youtube and only on firefox when on other browsers, yes I unchecked hardware acceleration, I restarted my firefox many times, I cleared the cache, today I turned my adblockers too, i thought it turned into how it was before but then it froze again and now I couldn't even see youtube it was just black screen on that tab, like what do I do here, do I switch browsers? It eventually starts playing again after I wait for some minutes but I don't want that, I want it to work like how it did before this happened. Why did it even happen?!

a web site continues to say mozilla browser need update to correctly access web page. I have downloaded latest update ESR for Firebox (using windows 7 OS) But web site still says I need update! Is it me or the web site that has the problem?

I want to be able to make voice and video calls via facebook messenger using my PC camera and microphone but, the message I get is that "voice and video are not supported on this browser (Firefox/Mozilla) . It is supported on other browsers. I really don't want to switch browsers, I love firefox. I did find a couple possible fixes via advanced WebRTC settings but everything seems fine, i.e. it is clicked on true not false. I need this soon, can we get settings changed?

Hi everyone, my website YouTube Thumbnail Downloader

is not loading properly on Firefox, while it seems to work on other browsers. Sometimes the page loads partially or shows styling issues. Has anyone faced a similar problem, and what could be causing it? Any help or troubleshooting suggestions would be appreciated.

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

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.

firefox is keeping me from accessing certain sites. why. do i need to switch to safari to access the sites. they do load on safari. can it be fixed or do i need to change?

I am unable to log into my Microsoft account normally. After entering my username and password, when I should be prompted to enter the two-step verification code, the webpage only displays the message: "Please retry with a different device or other authentication method to sign in. For more details, please see this link."

To resolve this issue, I launched Firefox using the -P command to access the Profile Manager, deleted my existing profile, and created a new blank profile. After logging into the new profile, I first signed into my Mozilla Firefox account to reload all my bookmarks. Without waiting for the synchronization of bookmarks and extensions to complete, I immediately visited account.microsoft.com and attempted to log into my Microsoft account, but the issue persisted.

Strangely, I opened a new private window and was able to successfully log into my Microsoft account through it.

Hello, I do not know if others have this problem, but when I try to access an Microsoft email account, using Firefox, it loads and then immediately logs me out. When I use a Firefox Private Window, this not occur. What might be causing this?

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

Hallo Firefox Community, ich habe seit 2 Wochen das Problem, dass ich mich mit Firefox nicht mehr auf bestimmten Seiten einloggen kann bzw. die Seiten sich bei der Anmeldung nicht mehr laden. Z.B. bei Klarna komme ich nicht mehr in meinen Account. Mein PC läuft mit Win7 Prof. SP1, das letzte Update von Mozilla lautet: Firefox 115.36.0esr (20260514164700) Details Installiert am: 20. Mai 2026 um 13:41:44 Status: Das Update wurde erfolgreich installiert

Hoffe hier hat jemand eine Erklärung dafür. Ich bin auf mein Firefox angewiesen, verwende den Browser schon eine halbe Ewigkeit. Möchte ungern auf einen anderen Browser wechseln.

Danke an alle!

Cant you help? I have no problems while using other browser. Thank you

I’m seeing a layout and font spacing issue in Firefox that doesn’t appear in Chrome or Edge. The page loads, but some elements shift after render and text spacing looks off.

I’ve tested in a private window, disabled extensions, and cleared cache, so it doesn’t seem profile-related. Any suggestions on what Firefox settings or DevTools checks might help?

Page where the issue is reproducible: dbrosmenu.com Thanks.

I have been unable to log into my email provider from their home page https://mailbox.org/en/ using Firefox. There is a progressive web app that "goes with" Firefox (if that is the right term) and that does not seem to work either. I get blank screens. I have succeeded in logging into mailbox.org in Microsoft Edge and in Brave. Can you please give me any clues as to what settings or whatever I need to configure in Firefox to be able to log into mailbox.org ?
