Firefox Community Forum

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 there, after turning on my computer in the morning, Firefox has been suddenly rendered utterly inoperable and pulls up a PR_CONNECT_RESET_ERROR for all websites. No matter what I do, including all other fixes previously suggested on the Mozilla forums and elsewhere, nothing seems to work.

Things that I've already tried and did not work include: - Pausing Kaspersky Internet Security - Resetting WiFi router - Switching to a different WiFi - Turning on troubleshooting mode - Resetting Firefox entirely - Creating a new profile - Reinstalling Firefox (several times) - Installing Firefox for Developers - Flushing DNS - Turning off proxy settings

I really don't want to be forced to use Google Chrome. Is there anything else that I can possibly do that can fix this?

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

I'm having this exact problem from here , but browser.taskbar.lists.tasks.enabled has always been set to true. Toggling it does nothing in itself in between restarting my machine. I am certain it's not a jump menu thing because this isn't about shortcuts (and besides the point, enabling the jump shortcuts from my OS side of things does not display it either way). I just want the stuff that the user in the above link listed.

Coincidentally, I had this exact problem a short while before, and I think it may have had to do with an update, because I remember Firefox updating at least twice fairly recently and it is in this time I've noticed this issue. The first time around it resolved itself, but this time it has not and I do not know the cause.

Unpinning/pinning the icon on the task bar does not resolve this either. It seems none of the conventional solutions in the past work, so unless I am missing something, something broke.

Hi, I can't use Firefox because a captcha won't complete loading. I have uninstalled and reinstalled, cleared cache and disabled add ons. I am using a vpn (PIA). Chrome and Edge both load and operate OK. Thanks in advance.

Captchas are an ongoing issue. Firefox seems to have a LOT more captchas than other browsers. Is there a problem between Mozilla and Google?

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

Hello, maybe someone else seen the same issue.

Why Firefox could respond with VP8 to the H264 request?

I'm trying to use the built-in PDF Editor features after finding out about it but every PDF file I open with Firefox has the options grayed out (as shown in the screenshot). What should I do to re-enable the features?

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

My computer (Windows 11) crashed while I was using Firefox--for the first time that I've seen, it did a full disk check. When booting back up, I was unable to use Firefox, since it said that my profiles.ini file was lost/corrupted.

After renaming the old file, I went back to the folder. It was easy enough to reinstall the add-ons that I needed, but I'm trying to get my bookmarks back. However, I can't seem to find them--the "bookmarkbackups" folders that come up are too new, and only one (the current one) has a file in it.

Any help will be appreciated! I'm not sure what I can do.

I use Protonmail - a web-based email app. They do not provide spellchecking, but say that the Firefox spellchecker should work in their email composer (it used to work so for me!) but, despite having Settings/General/Spellchecker ticked, and a dictionary (GB) selected (and, I see, the spellchecker working in this dialogue box) it is not working in the Protonmail composer.

Help!!

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

Before today, my 1Password 8 password manager worked just fine with Firefox browser on Windows 11. I updated my Firefox browser to 106.0.1 (64 bits) today and all of a sudden my 1Password manager stopped filling in my usernames and passwords for me into my logins. How do I get this functionality back so my 1Password manager works with Firefox again? Is there some setting that I failed to update in Firefox? Thanks. MR

Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

Firefox is, without a doubt, the best browser I have ever used, and I mean it. It's privacy oriented, great GUI, and is overall customizable. But, there are definitely some things which need improvement ASAP, such as the following: When I mouse over the top of my screen, Firefox semi-exits full screen mode and displays the toolbar. It is extremely annoying. Please make this an option somewhere; for me, even a hacky fix will do. Please, just help me get rid of it. Thanks :)

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]
