Firefox Community Forum

Hi, since some weeks I'm unable to access some websites with Firefox, cause I get 403 errors, for instance https://www.bexley.fr/. It works well with Chrome on the same computer+same OS, or with a newer version of Firefox on W10 (same computer, dual boot), but with my W7 and Firefox 115.35.1esr I can't access them because of that error. Any idea how I could fix that ? All my computers on W7 and the same version of Firefox are concerned. Thank you.

After the last Firefox Update, I can no longer log into my healthcare website. It loads login screen, enter information and it fails to redirect, returning to login screen. mymercy.net works fine with Edge and Chrome. But I have Firefox set as my default to switching is a pain! I have cleared everything.. reloaded firefox and it still does the same. Tried it with 3 different computers with the same result, so there is something about the new update that mymercy.net doesn't like. any suggestions?

Using Firefox, when I try to sign into Walmart.com I get a 'we are having technical issues, please try later' message. I tried using the Microsoft Edge browser and I logged in just fine. This issue just started. I cleared the cookies and cache data thinking this might help, but it did not.

Any suggestions will be appreciated.

Contributor note: The OP has also stated that the Private Browsing Mode resolves the issue. See /questions/1579683.

A radio station https://www.wfmt.com/schedule/ that has run successfully until today in Firefox no longer does, There is momentary blip of sound but then silence. It runs fine in Chrome. Another station continues to run successfully in Firefox

Since the latest Firefox update, I cannot load my primary banking account, and one of my work websites won't load. I can access both of these sites on other browsers.

Unfortunately the paste is broke once again, but differently! When I copy text from another website (e.g. Wikipedia articles or YouTube video titles) and try to paste the values only (ctrl + shift + v), nothing happens except for a little black box appears that says "paste." Doing a normal paste works and pasting (whether values or otherwise) within the google sheet works as well, only between sheets and another website.

can no longer upload photos to iCloud. Doesn't matter if I am on my laptop mac or at work on a iMac. I can use the same two computers and upload the photos to iCloud if I go thru Google instead. Is this a Firefox issue? How to fix?

Atttachment: I get the same "There was a problem...." pop up on my laptop and iMac, doesn't matter if I am uploading one photo or 100. Thanks

'bold text YouTube is "acting insane, sound plays/picture is frozen. Can't pause it. Also can't start it! Ads play on without option to skip. I got some notice that YT was changing something, I think it is broken. I managed to get a video to play on MS Edge, but I normally do not use that. I cleared cache and ALL of that, rebooted computer, etc. connection is good. Searches are fine on firefox, Other sites are fine on firefox. . IT IS YOUTUBE! It is SO bad that now with my mouse, the arrow and hand are NOT showing up on the actual screen where video plays. Right now on here it is fine. but on youtube? no.

Some faces of a 3d box are now invisible. The HTML is correct and the Inspector shows the faces in pale blue correctly. This worked for many months before the latest update to Firefox. I tried it in Safari and it worked, but I am used to Firefox. I tried Firefox for Developers and it worked until the update today, 5/1/26. Please help.

Issue persists on Incognito Mode and it goes away if I use different browser.

Since 2 days issue like this happened and it is retroactive meaning all previous conversations are also blank, all replies of chatgpt are blank except replies with image generation, those are fine.

Before you recommend me to do something please keep in mind that Incognito itself does not help.

I am able to share that chat, paste it in my firefox and page is blank. https://chatgpt.com/s/t_69f4b354cc188191a7959c2d443fed9d

I can use this adress on different browser and it works fine

I have been quite unable to view comments on www.telegraph.co.uk. The page simply does not appear when I click 'comments'. I have done a Firefox back to defaults refresh which was successful but no joy. After a look around the internet for solutions I installed Chrome which worked first time and has continued to. Why does Firefox fail? Thanks

Why do a number of familiar functions in familysearch.org in a tab in Firefox in Windows 10 in a laptop computer fail in the last few weeks with the message: Oops, something went wrong. Please refresh the page. topped by a triangle with an exclamation point inside? Question 1.

Is this message generated by Firefox? Question 2.

Could this failure be caused by a timing out of some impatient wait loop? Question 3.

When I start familysearch.org in a tab in the Edge browser all these familiar functions work. I have noticed that my whole system seems to be running slower in the last few months. I have been running familysearch.org in a tab in Firefox for years without this failure. Refreshing the page as advised by the message never works to accomplish the function. The functions in familysearch are Details for a person, Sources for a person, or the Tree for a person. There were even cases a week or more ago when the Details for a person were visible only down to the display of family where the error message would appear in place of the family information without affecting the earlier data.

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

I can't sign into my RBS Digital Banking page using Firefox. The display flips back and forth uncontrollably from Login page to Are You still Here? page. Login via Safari is as normal .. but Firefox is my preferred browser.

I was able to use Firefox for Animoto then for some unknown reason my project disappeared. I can access on Safari. When I try to open Animoto.com in Firefox a page comes up with My Projects page plus Animoto's Create a video and that is all that shows, the page is inactive. Same when I try to log in to my account. My computer is MacBook Pro Tahoe 26.3. I would be very grateful for a solution.

Hello, I am facing a strange issue while using Firefox browser. When I try to play LetterBoxed NYT, the game sometimes gets stuck on the loading screen or loads very slowly. The same website works fine on other browsers like Chrome and also on Android devices, so I’m not sure if this is a browser compatibility issue or something related to caching, cookies, or browser settings.

I have already tried clearing cache, disabling extensions, and updating Firefox to the latest version, but the issue still appears occasionally. Could this be related to browser security settings, DNS resolution, or performance optimization? Please guide me on what settings I should check or change in Firefox to make this web game run smoothly.
