Firefox Support Forum

Hi there, my name is Alvimutmex. Every time a webpage loads with the Mozilla browser, a "not supported" message appears. Upon examining the settings, I found that Mozilla has to be updated. Would you kindly assist me with updating Mozilla? For example, I receive an error notification when I try to open (https://pdfmedicalbooks.com/).

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

I've been noticing that when I click History > Clear Recent history, after clicking and going back to History, it hasn't removed everything. I have Firefox on my Android phone which is set to clear history upon close. For for unknown reasons, its leaving sites from both desktop and phone apps after clearing.

I'm running Firefox v 115.9.1esr on my Mac.

Any ideas?

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

Hi there! Every time i go onto a site like YouTube, Chess.com, ChatGPT etc, it asks for my login each time and i know there is a setting for it to remember me so i do not have to log into my account every time i use the site but I have looked everywhere and still fail to see it. Where about can i turn this setting on so i do not have to sign into my profile to use the relevant site. Thank you.

I have a NAS server, where I save all my data. When I type the local address 192.168.2.10:5001 I always get the warning That this is a malicious site. I havo enter I know the risk etc. which cost me time and is useless, since my NAS server is under my control.

I have tried to put the server address in several exceptions, but they disappear.

How to tell Firefox that my Nas srver is safe?

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

The 'add "outlook.live.com" as an application for mailto links' keeps popping up continuously after I click to X to delete the banner message. How do I disable it? Firefox should have a "don't remind me again" option. I do not want to add mailto links or make any changes. Thank You!

Hi I wish to have Firefox 125.0.2 and 124.02 'separate instances', not different profiles...

I already have 125.0.2 installed with various Profiles.

I found a 'few' links and they were quite 'cloudy' and also since Firefox (now) does not have the 'ask you WHERE to' install... I vaguely remember years ago, it was possible.

I do not mid doing tweaking, I also already have backups of profiles, just in case!

Thank you in advance M

PS it seems Mozilla does not want us to install multiple instances (perception)!

Since the 2 APR 2024 FF update, Washington Post articles are not displaying fully. When opened, the article flashes the full version, then only displays the top photo and the first two paragraphs. When opened in EDGE, all articles open fully as expected. This issue is only occurring in FF.

Actions taken: Cleared cache, same result.

Please advise.

I use Firefox as my browser but since yesterday I am unable to use it. Each time I click on the firefox icon I am directed to a French Microsoft browser - are you able to help?

Accidentally closed browser with many multiple tabs open. Tried to restore history but option was grayed out. Tried several times but was not able to get back to the original browsing window with the multiple open tabs.

Would really appreciate help on this, if possible, as the many multiple tabs contained family history research that will be difficult to impossible to duplicate.

Thank you.

Once updated Firefox all old tabs didn't open ( and it was not possible to restore them anymore). So I'd like to restore all old tabs of yesterday session. Really important for my work. Looking forward to hearing from you asap. Regards, Orlando.

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!
