Firefox Support Forum

I am using the extension request control on nightly(https://addons.mozilla.org/en-US/firefox/addon/requestcontrol/). I want to know if there is a rule which removes the amp part from the urls. Example:

Amp link : https://www.republicworld.com/amp/entertainment-news/hollywood-news/spider-man-no-way-home-second-trailer-release-date-revealed-all-you-need-to-know.html Original link: https://www.republicworld.com/entertainment-news/hollywood-news/spider-man-no-way-home-second-trailer-release-date-revealed-all-you-need-to-know.html

This morning I noticed new bookmarks on my desktop were no longer syncing to my Android phone. When I tried logging out and in again, I could no longer login on my desktop. Each attempt generates an "Unexpected error" message.

I have already tried the Refresh option from the troubleshooting menu. I also tried uninstalling and reinstalling. After both I am still getting an "Unexpected error" message.

I have also attempted to create a new profile, but attempting to enter an email address produces a 500 error.

Any ideas?

Bit of a niche question hope someone can help.

I’m running some website testing and have a script set up to open Firefox at regular intervals using Selenium in python, run tests and exit. Running it in a MacBook using Catalina and have the latest versions of Firefox. I tried a different MacBook as well.

Randomly, after running enough tests, it will fail to launch, throwing and error code “can’t quit and exited process”.

Once this happens, I can’t open Firefox at all, even manually. The icon just bounces and fails to launch. Oddly enough, I can’t launch Chrome either, even if I haven’t launched it since restart. Restarting my computer will fix the problem always.

I’ve tried running in headless mode to, no avail. Any ideas here?

I have files on desktop have sent pictures to Firefox. I'm afraid to hook my PC up to Ethernet because I saw it in the files. Networks 26282d. 26282_5g. Qualcomm Atheros AR8152 PCI-E Fast Ethernet Controller (6.30) is on my desktop files. I can access View all Events. I need someone to get files or show me how. I cannot move my cursor off this because tis is the only file I can access. I was in files and when I click on one it turns white can't get access my cursor picks up folder or file and puts it in another place. What can I do?

I have a corruption of a “search” link in my bookmarks. I would like to learn how to , through software or other means, remove these thousands of bookmarks on the computer and then sync the good copy to the cloud. There is a special file Firefox produces on windows 10 machines that is large - due to this corruption? I would not like to delete the computer file since I would lose the good bookmarks also.

I recently got a new computer and could not download Firefox. I have tried several different ways and keep getting the same results. On Microsoft Edge when I’d click download it would say the page can’t be reached. So, I tried Chrome, and it says that it isn’t connected to Internet. It is only when trying to download Firefox when I encounter this issue.

My Mac desktop won’t sync. I have the correct ID and the correct password and generated a recovery key from my iPhone do use on the desktop. I keep getting a message failed to connect to the server. I then re-generated a recovery key and tried again. No luck. I’m scratching my head on this one. Any help is appreciated.

While updating FF on my Windows 10 laptop, I received an error from XULRunner. Platform version '75.0' is not compatible with minVersion > = 74.0.1, maxVersion < = 74.0.1. Now FF will not open. Help?

I am in another time in short time with same problems. Firefox don´t want to start any downloads. It can be small file in pdf, install files or larger files. In all cases it failed. I can not hear any sound in Firefox as printing is impossible. Exactly same operations in Edge browser working just normal. There I can dowload, listen music or hearing other sounds, as downloading is working normal.

I restored PC to early date but improvment isn´t done, so I am same trouble

I keep getting a message that a web page is slowing my browser down. And it is terribly slow. How can I get rid of this frustrating issue? I think I even know the web page that it is.

My Canon Printer TS55055, refuse to work with my PC ASUS Intel Inside Core13 Window 7, Nvidia. Each times, when I want to print something I get this message "Your printer is not connected" Each times, I try to to connecte it, very rarely I succed, but the day after It starts again and again. It's stressing, because when I need to print, it's always a mess ! ! ! What can I do Please ! an answer in french will be appreciatable for me.

Thanks a lot...

W10 and newest update are not compatible. I seek help using Android, because firefox is no longer usable on Windows 10. It started with the tab toolbar using up a large part of the screen and fonts being huge. When I tried to adjust fonts they became too small too read. Dwngrades threaten my profiles, a real low blow. What do I do?

I'm using FF 89.0.2 on MacOS and I want to authenticate my user with a certificate. To that purpose, I imported the certificate (Certificate Manager / Import / ) and I can see it. However, when I make my request to the site, the authentication fails as if the certificate is not transferred in the request. Any suggestion of what is going wrong? Thanks - C

I have installed browser and I'm trying to request for data to some websites like social media but from my browser no one serves are responding and I have stable internet connection to my laptop please can anyone help me with this issue..

There seem to be an issue support for glibc 2.34 planed to be added in Firefox 91, any chance to issue a 90.3 hot fix to include support even if it's a few days early?

 This is an issue affecting this Distro:

Hello, since one week it is impossible for me to login at amazon.de from my Windows Laptop with WLAN Connection. After entering my Username and password, i do not come it at amazon.de. I have to connect my laptop via network cable with the router. Then it works. What can i do, that it works again with WLAN ? I have an Apple Tablet to and from there the login works. So i think the reason for my problem is not at amazon.de ? Sorry for my unprofessional english :-) Is there anyone who has an idea? V.
