I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

Greetings from North-East of France, since a few weeks ago I'm seeing a (sort of) pop-up window suggesting to login with a Google account (see the screenshot attached). I've done some internet search to find out how to get rid of it, but the only suggestion I get is to modify an option in a Google account. However, I do not have a Google account! How to get rid of this disturbing pop-up? I already use Adblock Plus and uBlock Origin, yet Google passes through them! Thank you in advance for any help you may provide.

I have my Firefox Firefox Privacy & Security History settings set to 'Always Use Private Browsing Mode.' Yet every time I open Firefox and visit the History tab, 'Recently Closed Tabs' shows a history of the websites I've visited. How do I disable this feature?

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj

How to do

Hello, I can't access the home router. 192.168.1.1 results in "Secure Connection Failed" and nothing can be done. How can I solve the problem?

I am unable to de-select the "Ask to save logins and passwords for websites" setting. The option is checked and I cannot "uncheck" the box. The texted is grey and the check box is a light color denoting it's not able to be toggled.

I searched for a solution and it's not the same problem as others are having where they have the the "never remember history" option enabled. My setting is "remember history."

I am a personal user, and this is my personal computer. I have admin rights on my computer. Running Windows 10 Pro.

Screenshot attached.

Thank you for any help with this.

Firefox is set to remember history, but every time I close it and re-open it, links in websites that once had purple text is now back to white, so I don't know what link I'm on, Firefox remembers this through history saved, why does it reset back to white text? Does it have something to do with bitdefender or bitdefender VPN? Can anyone else test thie out with firefox and bitdefenders full security on? Firefox is set to save everything by the way. Only started happening after installing bitdefender.

Obviously Firefox/Mozilla makes ~80% of their incomse $ by shipping the browser with google as default search engine, which is a privacy nightmare but who cares, it's for the money... So my best bet would be that's also the reason the default mailto suggested by firefox is google, is that correct? Does that mean something of google ins injected into Firefox? Look i have no idea to be honest, i do hate google and now im woondering where is the gmail logo comming from, is it stored somewhere inside of firefox? Is it just the logo or might there be more google crap injected to firefox behind the scenes?

Hi,

No matter what I do, a google dialogue box encouraging me to use google for password management, pops up every time I go to a site, new or existant.

I've gone into my google account to disable such requests, and, indeed, otherwise use google for nothing....not even search............but they keep coming anyway.

am using ubuntu 20.04, and no other utility or code is giving me this trouble.

I want to stop this dialogue box and eliminate any code in firefox or ubuntu which supports it.....as I have no idea why this box showed up....one day it just started.

Many thanks!

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

So firefox dev edition makes connections after booting the pc, even when i did not open it. Now i dont think its a big deal because so far i can tell those connections to the adress 127.0.0.1 should be only local connections that dont leave my local network, right? Question is, why does it do that? The standard firefox browser doesnt ever behave like that, so why does the dev version? What i dont like here is the fact that a program does things on its own without me interacting with it, firefox is a browser and should only be active when i use it, not on its own. So what are these connections and why are they there? How do you disable the browser acting on its own? I did not install the maintenance service.

I am running Firefox 118.0.2 64 bit on windows 10 22H2. For one particular website I get a 403 error on Firefox, the site opens normally on Edge. I do not have any add ons or extensions that block websites. I have cleared cache and cookies and tried to open the site in troubleshooting mode, no luck. I have also disabled BitDefender, same results. Any suggestions are appreciated.

I've posted before but no answer as to why Firefox labels Paypal as an unsafe site. I don't know where to change settings to allow it without the warning. I've just ignored the warning and continued but it is annoying.

Hello, I have my privacy settings set to NOT save credit card information yet in this past week, on two different new to me websites, my credit card information was already there. Why would this be happening and how do I stop it? Thank you so much! Julie

Remember search and form history. This setting always resets to false after the latest two FireFox updates and I need to enable it again.

After logging out and back in the setting is disabled again. I've removed all plugins and extensions I've added and the issue persists.

I've tried Places Database : Verify Integrity but the issue persists on very Restart or loggin. In the past I've even removed FireFox with a 3rd party uninstaller to remove all remnants of FF but, as a very long term user of FF (right from the early Win XP days), this issue pops up from time to time and it's really starting to become extremely annoying.

Apart from Refreshing FF or the total nuke and reinstall option, what else can be done to stop this issue?

Thanks.

Apparently my firefox updated yesterday ( aug 9 2022), it now shows I'm running 91.12.0esr. However it now says I can't use my old profile, stating: "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile..." So, how do i go about retrieving all of my passwords and get them into the new profile?

Hi,

Since recent updates to Firefox I get a purple pop-up listing Trackers at the bottom right of my screen every time I open a new webpage. I'm happy with my PC security settings and have good protection software running - but this pop-up listing Trackers is becoming a nuisance.

Is there a way to stop Firefox displaying the Tracker notification pop-ups whilst still intercepting and blocking them in accordance with my security settings?

I see that other users have asked the same question, but it does not seem to have been answered yet.

Thanks,

Peter
