Firefox 技術支援討論區

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

A recent update to Firefox browser seems to have changed how caching works for websites. I've noticed it mainly with Reddit and their 'random' feature. I can only go to one random sub-reddit and then from that point forward it will only go to that same sub-reddit when I hit the Random link. For instance if I hit random and it takes me to say www.reddit.com/r/Ohio/ then from that point on I only get the Ohio sub-reddit when clicking the Random link. If I clear my cache and reopen Firefox I again get one click on Random and then any further clicks take me to the first, random sub-reddit.

This is not replicated in Microsoft Edge or with Firefox in private windows. I have disabled all of addons to see if one of them was causing this behaviour but it made no change.

Hi. In the past week, my Firefox has been giving me this message for many sites - all of which I've landed on before and I trust. Firefox wants me to contact the website owner which is not do-able. Any suggestions? Thx!

Here's the error msg I get: An error occurred during a connection to www.google.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.

Amazon "Returns & Orders" page will not load... Mac/Firefox computer even it trouble shoot mode. Page just continues to partially load and repeats until I stop it.

Background: I am on the Beta track, currently running 98.0b4 on Mac OSX 11.6.1, until kinks are worked out of Monterey.

Issue: One of the latest FF upgrades has killed my ability to login to Netflix. I get an orange popup field stating "Incorrect password. Please try again or you can reset your password." The password is fine, as I'm able to login using my backup browsers, Safari and Vivaldi. The issue persists when I try to log in using a private window that doesn't allow any add-ons, so I don't see that as the issue.

Firefox is still my preferred and default browser, so I'd like to see this resolved before.

Certain site show what looks to be Chinese writing in the menu and description. Videos for those site will not play. This just happen today. Is there something going on with firefox? what would be the best fix?

I have always ordered my groceries through HY Vee Aisles on line. The display is not the same on firefox as is previously was. I have to go to Chrome. I have cleared everything, restarted and gotten rid of cookies.

Firefox is steadily being unusable for me. On numerous occasions websites fail to show log in pop ups etc which work without issue in Chrome. Latest example : https://www.gog.com/en/games Clicking "Sign in" should show a pop up to allow me to sign in. In Firefox this does not show. I thought it may be a "pop-up" issue, so deselected "Block pop-up windows" in settings. Still the same. I added the website as an exception and still the same. Anyone have any ideas what is going on ? TIA, ZTB

After the most recent update to the browser, I am no longer able to successfully login to many websites. Example for me include: Xcel Energy, Aol Mail, my local City Utility website and no doubt others I have yet to discover.

I know this is a browser dependent issue because Google Chrome is still able to access these sites just fine, but after the latest update to Firefox it no longer can.

It's able to load the login page and the site, but login in specifically returns either an error that shows on the webpage, or the URL displays some form of error code. Or in AOLs case it simply says "Uh oh. Looks like something went wrong. Please try again later." with a length authorization error code in the URL.

Any help with this would be appreciated. I've cleared Cookies, Cache, Active Logins and every other History Clearing option set to "Everything" as the length of time back to clean-up.

Like I said, this is a Firefox dependent issue due to Chrome accessing these sites just fine. I'd rather stick with Firefox over moving to Chrome but if no one can solve this problem then I guess it'll finally be time to ditch Firefox sadly, even though I've been using it since the early 2010s.

I'm getting a blank/black screen when I try to signup for Disney Bundle....

I do not know why you keep having this problem. Please advise! Vicki F Konnecke

How can I fix this? Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to 4njbets.us.betfair.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.
