Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

No way to ASK a question in the Monitor section, there is no GET HELP button.

Application error: a client-side exception has occurred (see the browser console for more information).

In general, getting to the "ask a question" button in the support website is like finding hens teeth.

Didn't there used to be a Discussions forum, where you could see all of the questions being asked?

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

  • Rebooted my computer several times
  • Deleted my history/cache
  • Disabled my extensions
  • Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
  • Updated my computer
  • Updated my graphics drivers
  • Refreshed firefox
  • Uninstalled and reinstalled firefox (and rebooted my computer)
  • Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.
