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?

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 cannot correct misspelled words when using Proton Mail. It has worked in the past, until recently. Perhaps the latest Mozzilla update? In the body of my email Proton email shows the words which are misspelled but I cannot right click to correct the spelling. Proton never seemed to support the "subject" field typos but did support spelling correction in the body of the email. The spelling correction works properly in Google docs.

Spelling correction is turn on in Firefox settings.

- Firefox 151.0.3 (aarch64)

- iOS Tahoe 26.2

Yesterday, Facebook started to take longer and longer to load a page. Whenever I tried to post something and it took forevahhhh for it to show up on the timeline. I had to reload and repost several times since yesterday. All other websites are loading up just fine, but Facebook has taken as long as 30 seconds, sometimes even more before it refreshes a page.

Then.. it got worse. All I could see was the Facebook logo in the middle of the screen and nothing else.

Then it got even worse. As of this morning, I can't even get any results when I google Facebook! I put Facebook into the search bar, click return -- and nothing happens, absolutely nothing.

I'm not seeing any problems with any other website. I have already restarted my modem. I have already cleared out the cache and the cookies. I have restarted my laptop three times. I even looked up Downdetector, but there aren't any problems with the website in general.

Those are all the solutions I've found when searching about this, but the problem is only becoming worse, with everything I try. If there's something I need to change in Facebook settings, I can't do that, because now Facebook is completely inaccessible.

This is only happening on my laptop. Mobile is fine.

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Bonjour Depuis un certain temps, je ne sais plus quelle mise à jour, j'ai des erreurs 406 à répétition avec Firefox. C'est très pénible!! ADBlock + is disabled Celà ne se passe pas, pour les mêmes pages avec Edge. Que faut-il faire? remettre Edge en navigateur par défaut? J'ai des exemples, mais je ne sais pas si je peux mettre les liens ici sans être censuré.

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 ?

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.

Lately I am noticing my browser takes a very long time to load certain websites (GitHub and Confluence mainly)

I don't experience the same issue on Google Chrome

When sites do load, they are often without stylesheets, and page elements do not work (possibly indicating scripts are not loading)

I am on iMac Tahoe 26.5.1. I cannot use Netflix, or HBO Max. Both say that my brower is out of date. My sofware indicates that my Firefox is the *latest version available. Please advise.

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?

I invoke Face Book but it FB page asks me to log in. Will not accept my user and password. Also You Tube is unstable. Only when in Firefox. Other browsers are OK, I can go straight in to site on other browsers.
