Firefox Support Forum

I've used gmail (with multiple email accounts) on Firefox for many, many years. I switch back and forth between my email accounts daily.

In the past few weeks, though, when I try to switch from my primary account to the others, it just defaults back to the primary. I've purged the cache, I've signed out and signed in. This does not happen on Chrome, just Firefox, which is why I've brought it here.

If I change the URL of the mailbox

https://mail.google.com/mail/u/0/#inbox

to

https://mail.google.com/mail/u/1/#inbox

It will take me to another mailbox. I can then change that number to get to the others. But it shouldn't be that way. So ... what is going on? How do I fix it?

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

Starting today, I cannot access my online bank account at Wells Fargo using Firefox (yesterday, I could). I can access this account using another browser and I can still access another online bank account using Firefox. I tried clearing the cookies cache, but no joy there. TIA for any help on this matter.

I want to be able to print my .docx files without saving them first. I went to General and Applications. .docx is not in the list, so I'm unable to select how it handles these files. How do I add .docx to the list of content types?

I've posted this problem before and did receive replies attempting to help. Unfortunately, the problem has continued for a long time (I think at least a year). I frequently can't access websites (e.g. Yahoo Mail) using Firefox but can using Edge or Brave. With Firefox, I get the following error message:

"Secure Connection Failed An error occurred during a connection to login.yahoo.com. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

I had hoped that the problem would be solved by a Firefox update but that has not happened.

I also regularly get the message "No Internet Connection" while using Firefox but, when I use Edge or Brave while the error message is displayed, there is Internet connection.

I'm using the latest versions of Firefox and Windows 10 Pro.

I've used Firefox for many years and really don't want to have to switch to, say, Brave.

It has recently come to my attention that Mozilla may not continue to support Firefox browsers installed on Windows 7 computers after Jan. 2023, when the extended support for Windows 7 ends. Is that correct?

Will Firefox continue to work, but not receive security updates after that date?

Will Firefox still work on a Windows 7 computer that gets patches from 0Patch?

Thanks!

Hi!

When Firefox 96.0 rolled out on my machine, I was surprised to see my old Firefox Quantum theme default to dark. I did not enjoy this new behavior, so I tried to downgrade to 95.0.2. After installing it, Firefox told me it couldn't load the user profile, as it was used on a newer version of Firefox.

I have no idea where exactly I read this, but some website contained an instruction to erase compatibility.ini and that would allow me to use the profile on older versions. Tried that and it actually worked. I did notice that, when Firefox tried to update, it would say it failed. I was hoping that, once I find a solution to the forced dark mode and I update Firefox, the problem would go away.

Fast forward a few weeks, I found AutoConfig and browser.theme.toolbar-theme option in about:config. So I updated Firefox manually and applied AutoConfig and my original problem was gone.

Fast forward more weeks, there is another update for Firefox. And Firefox was still unable to automatically update. So I tried reconstructing compatibility.ini, which I did fully. But Firefox still won't update.

At this point, it's been like 3 months with a crippled user profile and I must say I'm tired of updating Firefox manually.

Is there any way I can fix this profile? If not, what exactly should I copy over so all my preferences, cookies, addons and themes get carried over to a new one?

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

Hi, for the long time when I have opened an PDF with external application, it was downloaded into system %TEMP%, then deleted after ext. app was closed. Very fine and expected.

Since ca. few weeks such PDFs are now downloaded to Desktop - and not removed afterwards! It's quite annoying to clear them again and again. I've checked, my %TEMP% and %TMP% are set correctly and writeable.

Today, when I had turned on my pc, apparently Firefox had updated (?) my browser and ALL of my bookmarks are gone!?? I had copied my bookmarks from my other pc that had Windows 7 onto my new pc that has Windows 11 several months ago and haven't had any issues (with the bookmarks) - until today. Any help would be greatly appreciated!

I am unable to sign in to my Florida Retirement System (FRS) FRSOnline account at frs.fl.gov on my desktop or my laptop computer. I can log in on my cellphone Firefox app with no problem. I have checked and my username and password are correct on both my desktop and laptop. I can also log in with no problem using Microsoft Edge. Help! I don't want to have to switch to Edge! Thanks

Since the latest update the whole browser screen is messed up. Elements are moving as I move the mouse, even the Bookmark menu and site controls. Tried to reinstall, no luck.

~~~SOLVED~~~ Hello guys, this is about some..adults sites, i'm just getting loading error on the screen. Sorry if that's inappropriate. Also recently, youtube videos can't play at 1080p, only 720p, even tho i know the video it's 1080p.

Error message when accessing business websites which use Cloudflare: "ERROR 1005 ACCESS DENIED DUE TO ASN 9009". This seems to be because Firefox is using ip addresses which are blacklisted. This has been checked with blacklist services such as DroneBL. I am not using a VPN. I constantly clear cache & cookies from Firefox and then restart the computer. I am not ignorant or stupid. Why is Firefox using blacklisted ip addresses? Is it because of M247? Is there any way around this extremely annoying problem? Thank you for your response.

Firefox refuses to show my website correctly on my MacBook Pro M1 Pro, using OS 12.2. All other browsers on show it correctly. Firefox on my iPhone and iPad show it correctly too. I have tried all the obvious things... refresh, clear cache, deleted the application and reinstalled. However, I still get the same disjointed view of my website.

Please see the first image of how it looks and the second image of how it should look doesn't seem to want to upload here!

The site is bodymind-fit.com

I just installed Add-on "Search by Image" with "Tin Eye". When I try to launch the program I get the Error Message, "Content scripts are not allowed on this page."

How do I correct this so that it works as advertised?

Hello. I noticed that Firefox (98.0.2) doesn't even ask if the file should be saved or opened with a program when downloading some file types. Unfortunately, these file types (e.g. GPX) are not listed under Settings --> General --> Files and Applications, so that I could assign them to a program or specify that they should always be asked. And I can't add these files somehow... I have also deleted the file "handler.json" in the profile folder, hoping to be asked then. But that doesn't happen. GPX files, for example, are assigned to the GSAK program in the system - but Firefox just wants to save them and doesn't offer the option to open them directly in GSAK. Does anyone know advice how I can get Firefox to give me the choice? Thanks a lot.
