Firefox 技術支援討論區

first: thank you that there is no german support.

firefox seems no longer to be able to download complete websites: "download < fehlgeschlagen> = failed"

sometimes, "retry" button seems to work, but most of css is missing then when loaded offline.

ms edge is able to download complete websites, and they can offline be loaded with firefox completely and correctly then.

sometimes, "retry" seems to work in firefox, but most of css is missing then.

Dear all,

When trying to connect to https://webmail.chu-rennes.fr/ using Firefox 81.0 under OS Catalina 10.15.5 I receive the following message:

'The requested URL was rejected. Please consult with your administrator.

Your support ID is: 6577542328905707819'

I do not have the problem by moving to Safari, though.

Any insight from anyone?

Thanks a lot in advance

Best

I have a custom add-on that I'm working on for my team. It's hosted internally on a server signed by our company's internal CA. The add-on is signed by Mozilla, but not hosted on AMO.

I am on the latest version of Fedora running Firefox 81.0. In the browser console I get this error relating to the URL for the addon when I tell Firefox to check for updates: "Certificate issuer is not built-in".

I have the company CA installed and when I navigate to the site in the browser, Firefox recognizes the cert. I've done some reading on the subject and seen several threads about it. I've tried a few things already, but most of the threads where a couple of years old.

I'm asking the question here hoping to figure out what the current state of the problem is and which settings I should tweak to have it trust the company CA or what my options are.

Thank you in advance for any support on the issue.

I have been using FF for many Years and kept everything in my profile to retrieve history and bookmarks even if switching the Device. Now since I was forced to do some update I could not lunch the browser unless chosing create new profile. I logged in to my FF account, did password reset, and I have nothing in the browser, no history, no folders with bookmarks although I haven't even change the device. What's wrong>?

I am unable to display my username when trying to log into 'Udemy' website. Under Logins & Passwords my Username and Password is saved for this site. When I click login button, the username appears momentarily and then disappears from the login screen. I have to manually type the username each time. However, the password is retained and no issues there.

Could not find any help articles on this particular problem. Tried unclicking hardware acceleration. Still no change.

Other websites appear to function properly except 'udemy'. Is this due to settings in FireFox or something not right with 'udemy' website?

My laptop was supplied to me in Dutch-speaking Belgium but has a US-QWERTY keyboard. I have installed Firefox but every time Firefox is updated the language setting changes to Dutch and the English (UK) option disappears. Every upgrade means a reinstall and reset of the language. This does not happen with Chrome or Edge.

How can I fix the options so that English (UK) remains the default on this PC.

I have a couple questions about the New Tab page:

    I can't figure out a way, or if it's possible to make my homepage be what a new tab opens up to.  When I first launch Firefox, it goes to the page I specified in Options.  But when I open a new tab, I have to click the home (shaped) icon to get there.  Is there a way to do this in one click instead of two?  This isn't a huge problem, but I seem to remember that I had that working in the past.  Just wanted to see what the reality of this is.

  The main reason I'm here is because the New Tab page has finally gotten the better of me.  I have 8 X 4 tiles on the New Tab page and quite a few of them are sites I only visited once or twice in the distant past (6 months to 9 or 12 or more).  But my email site (which I visit far more frequently than all the others combined) comes and goes.  One time, I thought it might be "just below the surface" and if I started deleting tiles it would come to the top.  I spent a good 10 or 20 minutes deleting tiles but only even older sites would appear.  Even if it can't be fixed, it would help my mental health to know that this is an actual known occurrence and not some elaborate cloak-and-dagger conspiracy to make me nuts!  (am not actual conspiracy lunatic, just questionable sense of humor)

I've just set up a brand new profile and copied all my important user data across, including the bookmarks (places.sqlite).

But now my bookmarks have no icons?

I have over 25,000 bookmarks so I don't want to have to load them all in order to get the icons back!

Cannot load 4k and 1080p videos on firefox in youtube and other sites, this problem exists only in firefox. when im using other browser videos work fine. i tried to turn off all apps and its doesnt help. My internet connection is good.

Some sites are missing favicons making the toolbar useless if I have to use text to identify them. I quit using FF because of this about a year ago as all the solutions on here did not work. Seems as though FF could fix this internally as it is not a problem on Chrome, IE, Edge or any other browser I have used. Why can't FF fix what seems to be very simple problem? Came back and it is still a problem. Again all the listed fixes that I have to initiate, have not worked. Why can't FF fix this through an update. I am not the only one who has this issue and it is exclusively a FF problem. Not a computer expert but this seems to be a VERY easy fix via updates especially since it has been an issue for literally years. Don't want to go back to Chrome as I like all that FF stands for, but... Thanks for reading

When going to site using saved login message " View all saved Logins " can be seen. If sombody else is using the system other than myself this will allow all login and password to be viewed for all sites. Other person could be wife or hacker or other. I cannot see that my system is secure when using Firefox. For me to be able to view all logins is a bonus but should NOT be available to just anyone who may use the system. Any comment please?

Hello ,

I tried to solve a problem and in the process deleted all my Profiles from \AppData\Roaming\Mozilla\Firefox\Profiles. After this I managed to recover the data from this folder (I had 3 profiles, not sure which one was active). I can see the bookmarks but not the saved logins. Is there any way to recover this information ?

I have a dozen tabs opened in one window and would like to copy all of the url's and paste them into an email. I can do it one at a time but would rather do it all at once. Can it be done? Thanks

My understanding is when silent print is enabled by print.always_print_silent, browser will take default printer.here default printer value get from print_printer. if print_printer value is empty , it will take from system default printer. so if i change the default printer dynamically , browser will automatically detects the printer. Am I right?
