Forum d’assistance Firefox

As soon as i start my computor with firefox i get this message: Warning you have virus. You must install re-captha-version-3-49.top. What is that? I have norton and norton says no virus. What shall i do?

Many complex websites that had no problem till the latest version of Firefox don't load any more with the newest version. If this goes on like this I have to change my browser. I used Firefox now for many years but it looks like I have to change, as there are no problems with other web browsers (Opera, Edge, Chrome, etc).

Aren't there a lot of feedbacks like mine?

SIncerely, Franz

Recently Twitch and WarGaming, as well as other advertisers, collaborated on "Twitch drops" Somehow, Twitch is able to determine which tab is on top and being viewed by visitors to the website. It's one thing for Twitch to know I'm visiting the website, and quite another for them to determine if in fact the tab I have open is front and center. Seems to me this is a privacy issue that needs to be addressed.? (I have not yet determined if this Twitch snooping is working in private tabs yet, but I soon will)

I'm a hiker and backpacker. I have recently begun using AllTrails.com to record my hikes making them easier to share with others as well as to save them for my own records. Everything works fine except uploading photos. This aspect of the app does not work at all in Firefox. It does work with MS Edge and Google neither of which I want to use.

I signed into Firefox on a lab computer that has too little storage space to install plugins (<1MB storage space left.)

Naturally, plugins did not install. I wanted to ensure that Firefox would not even attempt to install them in the future, so I set the browser not to sync add-ons.

I don't know whether what follows is because of that setting, or because I set it too late. In either case, my dozen or so plugins on my main computer have now all been uninstalled. I don't know the names of all the plugins I was using anymore.

1. Can I recover my automatically uninstalled plugins? 2. Can this bug be patched?

My laptop died. I purchased a new one and pulled the SSD drive from the dead laptop and hooked it up to the new laptop with a SATA to USB cable and have access to the drive now. How do I pull all the information that was in Firefox (bookmarks, open tabs when laptop died, etc.) from the old drive to the new laptop?

I can no longer request further information on sites where it is possible to click and the result will be displayed. For example: I read a national newspaper on-line. After reading the article I then have the option of reading subscriber comments. When the button is pressed page says it is loading - but nothing happens. If I then switch to Edge - no problem. So I guess the problem does not lay with the newspaper. Many thanks for your help.

Hello Mozilla Support, I want to ask how to turn off suggested websites on my home shortcut. I searched on the internet, but everything I tried didn't work.

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

I would like to remain logged into google and youtube after i close firefox. After clearing my history once, i now get logged out every time i close firefox.

Please help :)

Kind regards,

Thomas Kunst

Hello, so I have some 4-5 add ons installed on my Windows computer and Linux machine. They both show up and sync well when I install or re-install Firefox when needed. But recently, I got a Mac and installed Firefox, logged in with my account and to my surprise it didn't sync all of the extensions. I waited, then quit and restarted the browser, still no luck. Even after shutting down the computer and then trying did nothing. I checked update despite having just downloaded but no luck yet. Must be some bug so please fix it

I am trying to go to ace hardware site. I get: Access Denied You don't have permission to access "http://www.acehardware.com/store-locator" on this server. Reference #18.26761cb8.1701661935.890df303 .

The search bar reads: https://www.acehardware.com. Why does my Firefox/Mozilla do this? How can I fix it? Help please, Wendyh

Hello fellow Firefox users, I sadly cannot use my Firefox (120.0.1, 64 bits, Windows 10) anymore as it is too slow to show a webpage... It's so slow, that I initially thought that I have no internet connexion at all on Firefox.

Can anyone help me figuring why my Firefox profile is so slow ?

Long story short:

- Until 2023-12-05, my Firefox was working normally.

 My parameters were "No HTTPS everywhere" and "No DNS over HTTPS (DoH)".

- On 2023-12-05, I was connected to an entreprise DNS (Mangling DNS).

 I cannot acces some website because of their local policy, so I changed my DNS parameters.
 I choose to use DoH with Cloudflare instead of the given DNS.
 Internet worked perfectly.

- On 2023-12-06 and 2023-12-07, same parameters, Internet worked perfectly on another network. - Since 2023-12-08, Internet is very slow. It need about 1.5 minute to get start.duckduckgo.com loading on any network.

 I thought it will not load at all (timeout ?).
 Others webrowsers (e.g. : Microsoft Edge) are correctly working.
 The "ping google.com" command is working normaly on windows with 2ms delay.
 The DNS on windows "Get-DnsClientServerAddress" are the normal DNS of the router.
 Even with reverting the DoH parameter to off, I do not get back my web browsing speed.

Troubleshooting :

- It's slow with "DoH and Cloudflare" activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me a list of Cloudflare DNS (IPv4) near me, different from the DNS (IPv6) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the same Cloudflare DNS.

- It's slow with "DoH and Cloudflare" NOT activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me one DNS from my ISP (IPv4), same value as the DNS (IPv4) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the Cloudflare DNS.

- In about:crashes there is not relevent crash (only old crash).

- I have not changed any about:config parameters in the 2023-12-05 to today (2023-12-12) period.

- I have run mozregression GUI with no problem.

 The program oppened succesfully start.duckduckgo.com .
 This website was choosen as it is an allowed website on every DNS.

- Firefox 120.0.1 is saying that it is up-to-date.

 And as of today, it is.

- I do have some extensions (12 activated) on my Firefox, so I try without extension.

 It worked but I do not understand why!
 * New profile. Using "firefox.exe -profile" I created another clean profile to see.
                It worked.
                According to https://www.dnsleaktest.com, my new empty profile uses both Cloudflare DNS (IPv4) and the router DNS from the ISP.
                Adding one-by-one most of extensions (6 now) to this new profile do not break yet my Firefox speed.
 * Safe Mode. Using "firefox.exe -safe-mode" I have started my corrupt profile without extension, JIT, etc...
              It worked.
              According to https://www.dnsleaktest.com, it uses only the router DNS (IPv4).

- I can send some result from about:support if needed, but it kills privacy...

Conclusion :

I do not understand why my main Firefox profile is not working correctly. I do not see strange things when troubleshooting. Nothing makes sense.

May someone help me figuring out?

Regards, eliotlencelot.

In the last week or so I am no longer able to log in to Ally bank when using Firefox. I contacted Ally Bank they indicated that the problem was with Firefox. I can login when using chrome or Edge with no problems. I use Windows 11

Recently I´ve encountered problems with (mostly) accessing nba.com. I don´t get the resultbar. Today klicking on one of the menue items (Schedule) Firefix refused to load the page claiming "Not safe". As you can see I´ve accessed the page a number of times. /Leif Arvidsson

And, apparently not even on this site (see "feilds" above)!

I have tried troubleshooting mode and a clean profile with no addons.

At least on YouTube, I've noticed this issue for several months.
