Firefox Support Forum

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

session is completely gone. I tried to restore it via various help articles and forum posts but without success.

I see a stg-backups-ff-126.0.1 fodler in my download folder which contains information about tabs that I had open. But I don't know how to use firefox to use that file.

I alos tried to the \sessionstore-backups folder with files named like "previous.jsonlz4" but I do not get the menu option for restoring a session.

from a file named "error-sessionrestore-1718212432477.txt": 1718212432149 SessionStore ERROR The session file is invalid: : TypeError: state.windows[0] is undefined(resource:///modules/sessionstore/SessionStore.sys.mjs:1163:11) JS Stack trace: initSession@SessionStore.sys.mjs:1163:11 onBeforeBrowserWindowShown/<@SessionStore.sys.mjs:2035:35

Hi,

I use ClassicPress (fork of WordPress) and I have a problem when requesting a password reset link for it.

When opening the email received to reset password in the firefox dev edition browser and click the reset link I receive an error stating that the link is invalid.

I discovered by trial and error that copying the same link and pasting it manually in a new tab of the same firefox dev edition browser solves the issue because then the link is recognised as valid.

This happened after the update I received last week.

I am a linux mint user if that helps in tracking down the issue.

If I open a second tab on the screen it says the connection has crashed and keeps doing it if you try again. If you reset it resets Firefox including the other tab.

FF just did an update and now I can barely use the browser. Its slow and then spins and crashes... it took me 6 minutes to just get this open and type this. All my links and sign ins are on it... ugh... How do I reverse the update? thanks

I receive e-mail from websites where I subscribe. Many times, the message from the sites (kelbyone.com, to name one) contain a graphic (jpg) that does not display in Outlook.com. Microsoft Tech Support is unresponsive. The sending websites refuse to help.

It seems to me that FF chokes on the length of the hyperlink. Here is a sample: https://kelbyone.acemlnb.com/lt.php?x=3DZy~GE2JaTN5XV.-wy5heOd~nAnuwAjluw2Z5PEIaOb5p8qy0y.0uJz2nRzit~yjvYwXncWJXCf657

If I paste the hyperlink into the search window, the page will load. When I forward the e-mail from Outlook to yahoo mail, the image displays.

I am running extensions Adblocker Ultimate and DuckDuckGo Privacy Essentials.

I would like help with this, at least, to identify where the problem is.

When I attempt login to store account, I get the error below. I have uninstalled/reinstalled Firefox to no avail; login works fine in MS Edge

{"sec-cp-challenge": "true","provider":"recaptcha","provider_secret_public":"6LfU2I4aAAAAABeLkTGHOItQ5XTtsv2BpEBonIj_","branding_url_content":"/_sec/cp_challenge/message-4-4.htm"}

I started having new tab crashes a couple of weeks ago on Firefox and Brave browsers. I have looked in the extensions settings and do not have any added extensions so that did not cause the problem. I also run Norton antivirus and Norton Ultimate utilities software and regularly clean out files and scan my computer for malware. Not sure if Ultimate Utilities is the problem since I have had other problems in the past with that program. Also, I wonder if Windows updates caused this problem? This has also caused problems in the past. To get around this problem I have to copy the link then right click on my mouse and open a new window the paste the link. Very annoying and time consuming. How do I fix the continual tabs crashing problem?

Greetings, every so often I'm having an issue loading pages for certain sites that aren't sketchy at all. The most recent one is TireRack.com. I'm shopping for tires for my car and Firefox is loading all the other sites I've visited but it won't load any page from TireRack. They are a legitimate shopping site. It happens from results of a Google search but I've also tried typing the main page of the site's address into the address bar, clicking various other links that display below the actual search result that go to other pages within the site, etc. The site loads fine in both Chrome and Edge. This happens every so often and it's always a legitimate site and the exact same behavior. I can't recall any other specific sites at the moment but it's enough to have me pretty irritated today as when I'm shopping I like to have multiple tabs open with all my options for comparison and price considerations and today I have to have one of them open in a different browser which makes it much more difficult to keep tabs on especially where I'm used to only having one browser open for all instead of having to remember that one of my options is open in another browser. I have glanced through my browser setting as well as my windows security settings but I could spend hours in there trying to figure out things and potentially breaking other things myself, which I don't like doing. Any suggestions or other info on what could be going on will be much appreciated, and thanks in advance.

Ray.

Hello,

I have been facing this issue when accessing Google Drive using Firefox, after selecting a file and clicking on "File information" option the "Details" and Activity" tabs simply don't load, as you can see in these screenshots.

Also, I found this thread also here on Mozilla Support from two years ago that reports the same issue. Apparently the bug was solved but ended up returning in most current versions.

I opened the current thread just to report this bug again. Thanks.

EDIT.: Another user reporting the same, his thread was archived: https://support.mozilla.org/en-US/questions/1422875

In early May I started having problems with Google on Firefox. Sometimes the Google home page won't load up at all. Once it does load up sometimes the searches work, sometimes the search just times out and goes back to the empty search bar, also when I click on links to websites they time out too. If I go straight to a bookmarked website, that seems to free things up and the next Google search I do will work. I've uninstalled and reinstalled Firefox but it doesn't make any difference. Google works fine on Chrome and Edge. Any advice would be gratefully received - please note I'm not technically minded! Thank you.

I can not log in to Outlook anymore on my computer when I use Firefox, but it is possible when I use Edge. But I prefer Firefox. What to do about this?

Lately, I have been getting a pop-up error when I start and close Firefox. The error reads: "XULRunner Could not determine any profile running in backgroundtask mode!"

I have found posts such as this one: https://support.mozilla.org/en-US/questions/1398228 and other posts suggesting to disable the scheduled task in Windows Task Scheduler, but none of the solutions have worked thus far. Anyone know of any other solutions?

I am trying to add an mp4 video to my website using the following code:

<video width="320" height="240" controls>
  <source src="images/###.mp4" type="video/mp4">
</video>

where ### is the name of the video file. I get the following error message:

"No video with supported format or MIME type found."

In the console the following is displayed:

"Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded. video.html All candidate resources failed to load. Media load paused. video.html Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)"

Runs just fine in Chrome and I have no pop-up blockers installed. Autoplay is set to be allowed for all websites.

Windows 11 version 23H2. Firefox version: 126.0 (64-bit)
